Fleming, Michael. "Cosmic Lotus, Rising". Thesis, University of Oregon, 2019. http://hdl.handle.net/1794/24555.
Testo completoAbstract (sommario):
Cosmic Lotus, Rising is a seventeen-minute, multi-movement experimental intercultural work for North Indian tabla and a fourteen-instrument chamber ensemble. This piece integrates playing styles from cosmopolitan classical music of European origin (US tradition), North Indian classical music (Lucknow lineage) and South Indian classical music. In this piece, I focus on the poignant image of the lotus flower, which ascends from the murky depths of desire and attachment to bloom in the light of realization. As one of India’s most recognizable flowers, the lotus is a symbol of creation and spiritual enlightenment. Its long stalk symbolizes the connection with its origins while the flower represents the enlightenment that human beings seek. In each movement, I utilize and integrate taal rhythm cycle structures to inform orchestration, melody, and harmony. This piece explores the concept of a lotus flower emerging, rising, and dancing, as love, growth, and cosmic energy make manifest.

Testo completoAbstract (sommario):
Une surface hydrophobe peut être rendue hyperhydrophobe si on la rend rugueuse. Cet effet, que l'on appelle souvent l'effet "fakir", est dû au piégeage d'air dans la structure. Une goutte repose alors sur une surface composite faite de solide et d'air. Nous montrons cet effet sur des surfaces constituées de forêts de micropiliers que nous avons réalisées grâce à des techniques de microfabrication. La situation où la goutte repose sur le sommet des micropiliers n'est pas toujours la plus stable : le liquide peut préférer plutôt remplir la micro-texture. Nous avons étudié la transition de l'état "fakir" à l'état "planté" de différentes manières : par des expériences de presse, d'évaporation et d'impact. Nous avons également réalisé des surfaces à gradient de densité de plots et discuté la possibilité d'observer des mouvements spontanés de gouttes. Enfin, nous avons étudié l'imprégnation de liquides mouillants et en avons tiré des lois dynamiques de l'imprégnation à deux dimensions.

Um estudo fitoquímico de L. corniculatus foi realizado e biomonitorado através de bioensaios de atividade antioxidante, antibacteriana e anti-inflamatória. O estudo fitoquimico foi efetivado através de sucessivas cromatografias em coluna de sílica gel e monitoradas por cromatografia em camada delgada, sendo as estruturas elucidadas através de técnicas de IV, RMN de 1H e 13C e COSY. A atividade antioxidante in vitro foi avaliada nos modelos como a capacidade sequestrante DPPH, potencial redutor e peroxidação lipídica. O efeito antibacteriano foi avaliado através do método de microdiluição o qual produz a Concentração Inibitória Mínima e a Concentração Bactericida Mínima. Finalmente, o efeito anti-inflamatório de Lotus corniculatus foi analisado no modelo in vivo da pleurisia induzida pela carragenina em camundongos, que é um modelo de inflamação aguda. Foram isolados três compostos: dois terpenos, o ?-sitosterol e o ácido oleanólico e um flavonóide glicosilado canferitrina. Após realizados os ensaios de atividades biológicas, nossos resultados demonstraram que Lotus corniculatus cv. São Gabriel possui importante propriedade antibacteriana e anti-inflamatória. Estes efeitos podem ser atribuídos aos compostos isolados como o ácido oleanolico, ?-sitosterol e principalmente ao canferitrina o qual demonstrou o melhor efeito farmacológico.

Testo completoAbstract (sommario):
Leguminosas forrageiras como espécies de Lotus., adaptadas às condições ambientais nos estados do sul do Brasil, podem ser uma alternativa importante para aumentar o fornecimento de forragem de alto teor protéico para o gado além de ter boa adaptabilidade a solos de baixa fertilidade. Uma das vantagens do uso de leguminosas forrageiras é a obtenção de nitrogênio a partir da simbiose com bactérias diazotróficas como os rizóbios. Este trabalho objetivou a seleção de rizóbios nativos a partir de amostras de solo de oito localidades do Rio Grande do Sul. Foram obtidos 259 isolados de rizóbios em plantas de Lotus glaber e 68 em Lotus subbiflorus. Estes foram avaliados quanto à eficiência na fixação de nitrogênio em simbiose com plantas, em cultivo em casa de vegetação, e quanto à morfologia colonial, produção de melanina e caracterizados geneticamente por comparação do perfil eletroforético dos produtos de amplificação do DNA genômico, pela reação em cadeia da polimerase com os oligonucleotídeos iniciadores BOX e ERIC. Apenas cinco isolados produziram melanina. Foram selecionados nove isolados para L. glaber que foram mais eficientes na fixação de nitrogênio do que as estirpes SEMIA 830 e U510, com índice de eficiência relativa de 88 a 132% e dois isolados para L. subbiflorus que foram mais eficientes do que as estirpes SEMIA 849 e SEMIA 850, com Índice de eficiência relativa de 128 a 159%. Na caracterização genética, observou-se que nenhum isolado apresentou identidade com as estirpes recomendadas, o que demonstra que nos solos do Rio Grande do Sul existem rizóbios autóctones capazes de fixar nitrogênio eficientemente em simbiose com Lotus glaber e Lotus subbiflorus, podendo ser recomendados para estudos a campo e para a produção de inoculantes para estas leguminosas no Brasil.Forage legume species such as Lotus., adapted to the local environmental conditions of South Brazilian States can be an important alternative to increase the supply of high protein content forage to the cattle besides the good adaptability to low-fertility soils. One of the advantages of using forage legumes relays on the acquisition of nitrogen from the symbiosis with diazothrophic bacteria such as Rhizobia. This work aimed the selection of native Rhizobia from soil samples of eight localities of Rio Grande do Sul. It was obtained 259 Rhizobia isolates from plants of Lotus glaber and 68 from Lotus subbiflorus. These isolates were evaluated on the efficiency of symbiotic nitrogen fixation with plants, grown in greenhouse conditions, on colonial morphology, capability of melanin production and genetically characterized by PCR genomic DNA fingerprinting using primers BOX and ERIC. Only five isolates produced melanin. It was selected nine isolates for L. glaber that were more efficient on nitrogen fixation than strains SEMIA 830 and U510, with relative efficiency index ranging from 88 to 132%, and two isolates for L. subbiflorus that were more efficient than strains SEMIA 849 and SEMIA 850, with relative efficiency index of 128 and 159%. Related to the genetic characterization, it was observed that isolates have no identity to the recommended strains, which shows that in the soils of Rio Grande do Sul there are autochthonous Rhizobia capable of efficient symbiotic nitrogen fixation with Lotus glaber and Lotus subbiflorus, which may be recommended to field evaluations and to the production of inoculants to these legume in Brazil.

How many times have you been dreaming as a child that you run and after a few steps your body detaches off the ground and floats into the air? Most of the leisure activities we cultivate today have deep roots into humankind`s history and are still confined to land. The history of hovering has been inspired by the great comic books sci-fi stories and was illustrated through Star Wars flying vehicles, which have been later translated into jetpacks and hovering bikes. What if you would be stuck somewhere in the middle way between dream and reality? What if this vehicle would be at first available to you in a virtual platform, so that you could train to fly it, and when you would master the art or flying it, you could try the real experience?

Testo completoAbstract (sommario):
The usefulness of RAPDs (Random Amplified Polymorphic DNA) to distinguish among different taxa of Lotus was evaluated. The following species were included: L. corniculatus, L. tenuis, L. alpinus, L. japonicus, and L. uliginosus. Several accessions for each species were studied. Following DNA extraction, amplification reactions were performed in a Hybaid DNA Thermal Cycler, and the product visualized according to a standard procedure. Twenty primers were used for each species/accession. Clear bands and several polymorphisms were obtained for all primers. A phenogram was drawn based on the genetic distance among the species. L. alpinus appears as the most distant species from L. corniculatus, followed by L. uliginosus, L. tenuis, and L. japonicus. With the exception of L. alpinus, these findings are in agreement with previous experimental studies in the L. corniculatus group. The use of a greater number of primers and increased number of species may provide a greater resolution of the systematics of these taxa.

Testo completoAbstract (sommario):
Post-anthesis colour change (PACC) is widely thought to be an adaptation to signal floral viability to pollinators, and may be a developmental pre-pattern for bird pollination in Lotus. Lotus filicaulis and Lotus sessilifolius are insect-pollinated herbaceous legumes with flowers that open yellow, shift to orange and finally, red. This thesis examines the ecological and molecular basis for floral colour change in these Lotus species. L. filicaulis was cultivated in a glasshouse from which pollinating insects (bees) were excluded, and the rate of colour change was recorded in both unpollinated and manually pollinated flowers. Unpollinated flowers from both the yellow stage and red stage were sampled for sequencing. The transcriptomes of L. filicaulis and L. sessilifolius of both colour stages were analyzed for differentially expressed genes and enriched ontologies. Pollination significantly accelerates PACC in L. filicaulis, consistent with the hypothesis that PACC increases pollination efficiency by directing pollinators to unpollinated flowers. RNA-seq results show the synchronized upregulation of the entire cyanidin biosynthesis pathway in the red stage of PACC of both Lotus species – possibly at the expense of adjacent pathways competing for the same substrate. This thesis is the foundation for understanding the molecular evolution of PACC in Lotus and will be useful in testing the hypothesis that PACC is a preadaptation to bird pollination in Lotus.Science, Faculty of

Testo completoAbstract (sommario):
An isoenzyme survey of several taxa within the genus Lotus was undertaken to provide markers for genetic research and to test hypotheses concerning the phylogenetic origin of Lotus corniculatus L. A preliminary study identified seven enzyme systems PGI, TPI, PGM, MDH, IDH, 6-PGDH and ME, that produced consistent clear phenotypes in L. uliginosus Schkuhr. Variation in phenotype with tissue type and stage of development suggested the presence of several isozyme zones in the phenotypes. Enzyme phenotype was constant for shoot tissue of plants older than six weeks. A second study examined recombination and segregation of isoenzyme phenotypes in interspecific hybrids, allo- and autopolyploids, and in L. corniculatus. Duplication and quadruplication of pgi2 loci in hybrids, amphidiploids, and in L. corniculatus was used as evidence that the latter is a segmental allotetraploid. A third study surveyed the occurrence of various isoenzyme alleles in L. alpinus Schleich., L. japonicus (Regel) Larsen, L. tenuis Waldst. & Kit., L. uliginosus and L. corniculatus. Lotus uliginosus had unique distinct alleles for several enzymes that did not occur in the other species. This evidence argues against the involvement of L. uliginosus in the origin of L. corniculatus.

Testo completoAbstract (sommario):
A utilização de pastagens capazes de tolerar o alumínio em níveis elevados apresenta-se como uma alternativa viável para contornar um dos principais problemas existentes em áreas de cultivo com solos ácidos. Entre as leguminosas forrageiras, o cornichão (Lotus corniculatus L.) destaca-se pela sua qualidade nutricional e versatilidade de adaptação. Em função disso, esse trabalho foi desenvolvido com o objetivo de selecionar plantas de L. corniculatus tolerantes ao alumínio, bem como analisar a diversidade genética existente entre estes materiais com o auxílio de marcadores moleculares do tipo microssatélites. Foram utilizados três genótipos de cornichão (Draco, São Gabriel e UFRGS) em solução nutritiva, contendo 200µmol/L de cálcio (CaCl2.2H2O), 100 µmol/L de alumínio (AlCl3) e pH controlado em uma faixa de 4,1 - 4,3. Realizaram-se dois ciclos de seleção, sendo as plântulas selecionadas pelo comprimento final das radículas. Posteriormente, testou-se o progresso alcançado pelos ciclos de seleção através de um experimento em solução nutritiva, semelhante ao utilizado nas seleções, com as populações originais e melhoradas, em quatro concentrações de alumínio (0, 50, 100 e 150 µmol/L) (AlCl3). Foram avaliados o comprimento inicial, final e o crescimento das radículas. Após o término do segundo ciclo de seleção, realizou-se a análise da diversidade genética existente entre os genótipos de cornichão estudados. Foram utilizados 18 pares de primers desenvolvidos para Lotus japonicus (Regel) Larsen e Trifolium repens L. As similaridades genéticas, com base no coeficiente de Jaccard, foram utilizadas para fazer o agrupamento dos genótipos pelo método UPGMA, através do programa NTSYS pc 2.1. O número de alelos e o conteúdo de informação de polimorfismo (PIC) também foram calculados para cada loco. A seleção em solução nutritiva mostra-se eficiente na seleção de plântulas de cornichão tolerantes ao alumínio. Os materiais analisados apresentam diferenças em relação a esta característica, destacando-se como o genótipo mais tolerante UFRGS F2, proveniente de dois ciclos de seleção. Os marcadores microssatélites revelam-se adequados para acessar a variabilidade genética entre os genótipos de L. corniculatus.The use of grasslands capable to tolerate high levels of aluminum is a viable alternative to bypass one of the main problems existing in cultivated areas with acid soils. Among the forage legumes, the birdsfoot trefoil (Lotus corniculatus L.) stands out for its nutritional quality and versatility of adaptation. Given the importance, this work was carried out to select plants of L. corniculatus tolerant to aluminum, and analyze the genetic diversity between these materials with the aid of microsatellite molecular markers. Three genotypes of birdsfoot trefoil were used (Draco, São Gabriel and UFRGS) in nutrient solution containing 200 µmol/L of calcium (CaCl2.2H2O), 100 µmol/L of aluminum (AlCl3) and controlled in a pH range of 4.1 - 4.3. Two selection cycles were made, where the seedlings were selected by the root length. Subsequently, the progress achieved by cycles of selection was tested in an experiment in nutrient solution, similar to that used in the selections, with the original and improved populations, in four concentrations of aluminum (0, 50, 100 and 150 µmol/L) (AlCl3). The initial, final and the growth of the radicle were evaluated. After the end of the second cycle of selection it was carried out the analysis of genetic diversity among genotypes of birdsfoot trefoil studied. Eighteen pairs of primers developed for Lotus japonicus (Regel) Larsen and Trifolium repens L. were used. The genetic similarities based on Jaccard coefficient was used to make the grouping of genotypes by the UPGMA method, using the program NTSYS pc 2.1. The number of alleles and the polymorphism information content (PIC) were calculated for each locus. The selection in nutrient solution was efficient in the selection of seedlings of birdsfoot trefoil tolerant to aluminum. The materials analyzed differ for this characteristic, with the genotype UFRGS F2, being the most tolerant. The microsatellite markers are suitable for accessing the genetic variability among genotypes of L. corniculatus.

Testo completoAbstract (sommario):
Les légumineuses sont capables d'assimiler le N2 atmosphérique par le processus de la Fixation Symbiotique d'Azote (SNF). Les petits ARNs (sRNAs) sont des molécules de 18-25nt qui régulent l'expression génique par similarité de séquence dans le cadre du mécanisme du RNA silencing. Parmi les différents types de sRNAs, les microRNAs (miRNAs) sont des régulateurs post-transcriptionnels qui jouent un rôle clé dans les interactions plante-bactérie. Nous avons choisi l'espèce modèle Lotus japonicus pour l'étude de la contribution des miRNAs dans la SNF. Premièrement, nous avons identifié les gènes principaux du RNA silencing dans cette espèce. Nous avons ensuite créé des lignées transgéniques exprimant le suppresseur viral P19 qui interfére avec l'activité des miRNAs. Ensuite, nous avons entrepris une stratégie de séquençage de sRNAs de racines et nodules, avec l'objectif d'identifier des miRNA impliqués dans la symbiose. Les données obtenues ont été employées pour l'identification de miRNAs: 16 familles conservées et 27 nouveaux miRNAs potentiels. Une analyse comparative des sRNAs a révélé que l'expression d'un groupe spécifique de miRNA conservés est induite dans les nodules développés: miR167, miR171c, miR172, miR390 et miR397. Des analyses génétiques ont révélé que miR167 et miR172 sont indépendants de l'infection par Rhizobium, ce qui suggère son implication dans le développement du nodule. En revanche, miR397 est non seulement surexprimé lors de l'infection bactérienne, mais aussi suite à la fixation effective de l'azote. En conclusion, ce travail confirme que les miRNAs sont des régulateurs géniques impliqués dans des différentes étapes de la SNFLegumes assimilate N2 through the establishment of Root Nodule Symbiosis (RNS) with bacteria from the genus Rhizobia. Small RNAs are 18-25nt molecules that regulate gene expression in a sequence-specific manner via a mechanism known as ‘RNA silencing’. Among the different types of smRNAs, microRNAs (miRNAs) are post-transcriptional gene regulators that, in plants, play key regulatory roles in plant-microbe interactions. In this context, we chose the model legume Lotus japonicus to assess the contribution of microRNAs to RNS. First, we identified the main RNA silencing effectors in Lotus japonicus, with emphasis on miRNA-related pathways, and generated L. Japonicus transgenic lines expressing the tombusviral silencing suppressor P19, which interferes with miRNA action. We then embarked on a smRNA cloning/sequencing strategy. The pooled sequenced data served as basis for the identification of miRNA genes in Lotus japonicus: 16 conserved and 27 potentially novel miRNA families. Comparative analysis of cloned smRNAs from root and nodules revealed that a discrete number of conserved miRNAs, miR167, miR172, miR390 and miR397, are highly expressed in mature nodules, as opposed to roots. Genetic analysis showed that the accumulation of miR167 and miR172 is Rhizobium-independent, as opposed to miR397. Further genetic studies showed that miR397 induction is also reproduced at the systemic level but dependent on the establishment of a successful N2 fixation, rather than on the infection by Rhizobium per se. Thus, our findings confirm that miRNA are important gene regulators at different stages of the establishment of Symbiotic Nitrogen Fixation

Traditionally recognized as the first of the great Buddhist treasure revealers, Nyang-rel Nyima Özer (1124-1192) historiographically reconstructed the Imperium into a golden age of Tibetan Buddhism. An analysis of his two early biographies demonstrates that he was among the first to recall an unbroken series of preincarnations in real historical time, which was a crucial link that led to the ascension of concatenated reincarnates like the Karmapas and Dalai Lamas. For Nyang-rel, his past life as emperor Tri Song-détsen (d. 800) provided the teleological karmic basis for his life as a finder of the old texts and relics deemed "treasure." According to his biographies and the two narratives that are attributed to him, Nyang-rel’s treasures were uniformly material objects extracted via quite mundane methods, though the discovery of old manuscripts seems to have been only an initial step in a process of compilation, redaction and composition that resulted in their reintroduction. Allegedly among these treasures was the first complete biography of the eighth-century Tantrika, Padmasambhava, which later became renowned as The Copper Palace. Much of this narrative was incorporated into the history of Buddhism entitled Flower Nectar: The Essence of Honey that is also attributed to Nyang-rel. Based on a comparative analysis of available recensions, however, I propose three hypotheses as equally viable alternatives to what has been asserted concerning the composition of these two texts. First, Nyang-rel did not consider his biography of Padmasambhava to be a treasure, but the tradition later manufactured a recovery narrative and accompanying title that promoted it as such. Second, Nyang-rel did not compile the Flower Nectar history. Third, based on oral, textual and mnemonic fragments, Nyang-rel produced a narrative of Tri Song-détsen and Padmasambhava that others developed into The Copper Palace and Flower Nectar. In sum, Nyang-rel was a progenitor of some of the most definitive aspects of Tibetan Buddhism, yet these very innovations ensured that he would be eclipsed by later adepts who, in adopting his claims and methods, revealed new iterations of his scriptures and narratives. He thus remains one of the most influential yet unsung figures of the Tibetan renaissance.

Gustin, Melissa L. "Eating the lotus : new critical approaches to neoclassical sculpture". Thesis, University of York, 2018. http://etheses.whiterose.ac.uk/20534/.
Testo completoAbstract (sommario):
This dissertation uses object-based case studies to explore how works by Emma Stebbins and Harriet Hosmer—and by extension, the broader field of American neoclassical sculptors—were influenced by the complex visual and historical field of Rome, 1852–1878. This project models different ways of reading and responding to sculptures which are complex works of classical translation, reference, and response, through an object-first and experience-based approach. I discuss four sculptures in three case studies: Hosmer’s Daphne and Medusa (1853, 1853/4), Stebbins’s The Lotus-Eater (1857/60), and Hosmer’s Pompeian Sentinel (1876/8). These case studies have been chosen for their rich, multivalent relationships to previous artistic models, texts, and visual spaces in Rome (both the modern city and the ancient empire). I bring together methodological and critical approaches that have not been previously used for American neoclassical scholarship, especially Eve Kosofsky Sedgwick’s definition of ‘camp’ and weak theory. I utilize literary models of classical reception, allusion, and intertext, theories of objects in relation to time and to other objects, ecological models, and archaeological theories. My object-first approach draws heavily on first-hand observation of sites in Rome and its surrounding areas, especially Pompeii. Within this thesis, I emphasize this first-hand experience along with the importance of travel to these sites as part of my research method through the strategic use of the first person and an emphasis on the intellectual, emotional responses to sites that I had. This reinforces my dissertation’s aim of enlivening the scholarly discourse around neoclassical scholarship as well as engaging in academic honesty, rather than upholding a dispassionate empiricism that does not reflect the methodological and critical approach of this project. These will be theoretically rich, chronologically complex, and emotionally engaged readings of these works, that embrace the multivalent, anachronic potentials of neoclassical sculpture.

Testo completoAbstract (sommario):
Lotus corniculatus L. (Legtuninosae), is a perennial herb common throughout Britain. Its main pollinators are bumblebees (Bombus spp., Apidae: Hymenoptera). This is a study of the ecological factors which are important to flowering and fruiting in the species, and some of their evolutionary implications. The work was carried out at Wytham Estate, Oxfordshire, U.K., mainly in an ex-arable field (Upper Seeds) and a more established grassland (Lower Seeds Reserve). The literature on self-incompatibility in L. corniculatus is reviewed; there are conflicting reports, but wild material is fundamentally self-incompatible. Plants in Upper Seeds are larger than in Lower Seeds Reserve. Comparative data on soil nutrients in the two sites suggests that the cause is the persistence of phosphorus from inorganic fertiliser. There is a positive, linear relationship between plant size, flower production and fruit production. The species regulates investment in flowers mainly at the level of the whole inflorescence, rather than altering number of flowers per inflorescence. Within individuals, there are no consistent trade-offs between number of fruit per infructescence, numbers of seeds per fruit and seed weight. Weather patterns only partially explain the flowering phenology of L. corniculatus. Timing of first flowering and peak flowering are correlated but are variable between individuals, and between years for the same individuals. They are not correlated with flowering synchrony. An individual's flowering pattern does not consistently affect fruit-set; the overriding determinant of fruit production is plant size. Selection is therefore unlikely to be acting on flowering time in this species. The production of large numbers of self-incompatible flowers does not seem to reduce fruit-set; pollinators do not visit enough flowers per foraging trip (perhaps because nectar production is low) for geitonogamy to become a problem. Seed predation by larvae of a chalcid wasp, a weevil and a moth differs between individual plants, but not consistently so between years. Seed predation is not consistently correlated with plant size, mean flowers per inflorescence, number of seeds per fruit or seed size. There is no evidence for selection acting on these traits through seed predation. Partially predated seeds are often viable, which may have implications for seedling demography. Seed predation and flowering phenology are not defmitively linked, strengthening the argument that flowering time is not adaptive in this species.

Resumo: O presente trabalho analisa a produção litográfica de Darel Valença Lins (1924 -) e Lotus Lobo (1948 - ) das décadas de 1970 e 1980. Estes artistas desempenharam papeis de destaque na produção e no fomento da litografia artística no Brasil a partir de contextos e referenciais distintos, no Rio de Janeiro e em Minas Gerais, respectivamente. Suas produções autorais apresentam novas direções ao passo que incorporam imagens apropriadas em suas gravuras e, ao mesmo tempo trabalham com novas soluções processuais para as impressões, de forma que suas obras enquadrem-se dentro do grupo de artistas que investigam a gravura como meio expressivo ambivalente, caracterizado pela reprodução e pela multiplicação da imagem. Suas litografias se apresentam de tal forma, que reajustam e recompõem as imagens apropriadas recodificando-as, gerando uma nova construção na qual o registro original não mais as representa, mas também não se apaga por completo, semelhantemente ao que fazem os processos cognitivos de memória

O trabalho propõe uma análise da produção artística desenvolvida pela artista e litógrafa mineira Lotus Lobo desde o final da década de 1960 até os dias de hoje, com matrizes de rótulos de embalagens descartadas pelas estamparias mineiras (especialmente de Juiz de Fora), em um momento de substituição de tecnologias de impressão. Destaco sua aproximação com a Pop Art — cuja produção, em geral, também dialoga com as artes gráficas ligadas ao contexto sócioindustrial —, mostrando as influências e as disparidades que impedem seu trabalho de ser meramente caracterizado como tal. Procuro refletir sobre duas direções de seu trabalho: a produção da artista plástica, por meio da apropriação das imagens dessas matrizes e de materiais de refugo industrial, como as maculaturas; e a pesquisadora que tenta manter viva a memória do design gráfico mineiro do início do século XX, seja por projetos acadêmicos ou iniciativas individuais, independentes, demonstrando a alta criatividade de sua produção artística e o lastro de suas contribuições.
This paper proposes an analysis of the artistic production developed by the artist and lithographer Lotus Lobo from the late 1960s to the present day, with matrices of packaging labels discarded by the printmakers of Minas Gerais (especially from Juiz de Fora), at a time when printing technologies were being replaced. I highlighted her proximity to Pop Art — whose works also dialogue with the graphic arts linked to the industrial context — showing the influences and the disparities that prevent her work from being characterized as Pop. I try to reflect on two directions of her work: the production of the plastic artist, through the appropriation of the images of these matrices and materials refused by the industry, as the stained printings (maculaturas); and the researcher who tries to keep alive the memory of the graphic design of Minas Gerais of the early twentieth century, either by academic projects or through independent initiatives, demonstrating the high creativity of her artistic production and the wide range of her contributions.

Testo completoAbstract (sommario):
Mestrado em MicrobiologiaO género Lotus engloba espécies com interesse agrícola, como é o caso de L. uliginosus, que possui capacidade de se adaptar a condições adversas e é utilizada em pastagens melhoradas. Este género compreende também espécies silvestres, muito pouco estudadas ao nível dos respetivos microssimbiontes, como é o caso de Lotus parviflorus. Neste estudo, fez-se a caraterização fenotípica e molecular de estirpes de bactérias isoladas dos nódulos radiculares de Lotus parviflorus e de Lotus uliginosus. Os isolados de L. parviflorus mostraram-se bastante heterógenos em relação à velocidade de crescimento, absorção de vermelho de congo e diversidade. Apenas um (isolado Lp11), de crescimento lento, revelou a capacidade para nodular espécies de Lotus. Taxonomicamente foi incluído na espécie Bradyrhizobium canariense, e obteve maior homologia nos genes simbióticos, com isolados de leguminosas da tribo Genisteae. Os restantes isolados não revelaram capacidade para nodular espécies de Lotus, e, taxonomicamente, muitos destes isolados não pertencem à família Rhizobiaceae. Para além da fixação de azoto, alguns isolados de L. parviflorus, revelaram a capacidade de produzir sideróforos (Lp6), de hidrolisar polissacáridos da parede celular das plantas e de inibir o crescimento de fitopatogénios como Phytophthora cinnamomi e Botryosphaeria corticola (Lp7a e Lp7b). Nos isolados de L. uliginosus estudados, apenas um (Lu13) foi incapaz de nodular plantas de Lotus spp., tendo sido classificado fora da família das Rhizobiaceae. Foi também o único de crescimento rápido e com absorção intensa do corante vermelho do congo. Os restantes isolados nodularam de forma eficaz L. uliginosus e L. parviflorus. Nodularam também, mas ineficazmente, L. tenuis e L. corniculatus. Os isolados com capacidade simbiótica foram identificados como pertencentes ao género Bradyrhizobium, com maior similaridade com as estirpes de Bradyrhizobium sp. isoladas de L. uliginosus de estudos anteriores e com estirpes de Bradyrhizobium japonicum bv. genistearum. Possuíram maior homologia nos genes simbióticos, com estirpes isoladas de L. uliginosus, em estudos anteriores, e também, mas com menor similaridade, com estirpes isoladas dos nódulos de plantas da tribo Genisteae.
Lotus spp. comprises species with a high agronomic value, like L. uliginosus, that can tolerate adverse conditions. It also includes wild species that have been little explored in terms of their microsymbionts. In this study a phenotypic and molecular characterization of bacteria isolated from the root nodules of Lotus parviflorus and from Lotus uliginosus was performed. L. parviflorus isolates were very heterogenous regarding the growing type, congo red absorption and genetic diversity. Only the isolate Lp11 was able to induce nodules on Lotus plants. This isolate is a slow grower and was classified as belonging to the Bradyrhizobium canariense specie. On the basis of the symbiotic genes it was close related with strains isolated from plants of the Genisteae tribe. The remaining isolates didn’t nodulate Lotus plants, and a lot of them don’t belong to the Rhizobiaceae family. Besides nitrogen fixation, some strains isolated from L. parviflorus, could produce siderophores (Lp6), hydrolyze cellulose and inhibit the growth of fitopathogens like Phytophthora cinnamomi and Botryosphaeria corticola (Lp7a and Lp7b). In the isolates of L. uliginosus studied, only one isolate (Lu13) couldn’t nodulate Lotus plants and was classified outside of the Rhizobiaceae family. It was the only one that strongly absorbed congo red and revealed a fast growing type. The remaining isolates of the root nodules of L. uliginosus could effectively nodulate L. uliginosus and L. parviflorus plants. These isolates also nodulated L. corniculatus and L. tenuis, however, they were ineffective. These isolates belong to the Bradyrhizobium genus, with high similarities with Bradyrhizobium sp. strains isolated from L. uliginosus, in previous studies, and also with some strains of Bradyrhizobium japonicum bv. genistearum. The symbiotic genes were identical to the isolates of L. uliginosus from previous studies, and to a lower degree to some isolates from plants of the Genisteae tribe.

Testo completoAbstract (sommario):
Birdsfoot Trefoil (Lotus corniculatus L. cv. Leo), is a perennial forage legume that has difficulty in establishing stands due to slow seedling growth, weed competition and herbicide sensitivity. The development of herbicide resistant cultivars would be of economic importance. Resistant lines were isolated after sequential selection at the callus, shoot and whole plant levels to the sulfonylurea (SU) herbicides Harmony (DPX-M6316, code name for methyl 3- ( ( ((4-methoxy-6-methyl-1,3,5,triazine-2-yl)amino) carbonyl) amino) sulfonyl-2-thiophenecarboxylate), or Classic (DPX-F6025, code name for 2(( (4-chloro-6-methoxypyrimidine-yl)amino carbonyl) aminosulfonyl)benzoic acid ethyl ester. In field and growth chamber tests the Harmony regenerant lines displayed an increased tolerance as compared to control plants from tissue culture, and from seed. Results of the evaluation of callus cultures of regenerated mutant lines signify stability of the resistance. Outcrossed seeds collected from field trials, and tested in vitro for herbicide resistance, indicate that the trait is heritable and that resistance may be due to reduced sensitivity of acetolactate synthase to SU inhibition. It is concluded that herbicide resistant birdsfoot trefoil cultivars can be isolated using in vitro selection.

Testo completoAbstract (sommario):
BACKGROUND:Sacred lotus is a basal eudicot with agricultural, medicinal, cultural and religious importance. It was domesticated in Asia about 7,000 years ago, and cultivated for its rhizomes and seeds as a food crop. It is particularly noted for its 1,300-year seed longevity and exceptional water repellency, known as the lotus effect. The latter property is due to the nanoscopic closely packed protuberances of its self-cleaning leaf surface, which have been adapted for the manufacture of a self-cleaning industrial paint, Lotusan.RESULTS:The genome of the China Antique variety of the sacred lotus was sequenced with Illumina and 454 technologies, at respective depths of 101x and 5.2x. The final assembly has a contig N50 of 38.8 kbp and a scaffold N50 of 3.4 Mbp, and covers 86.5% of the estimated 929 Mbp total genome size. The genome notably lacks the paleo-triplication observed in other eudicots, but reveals a lineage-specific duplication. The genome has evidence of slow evolution, with a 30% slower nucleotide mutation rate than observed in grape. Comparisons of the available sequenced genomes suggest a minimum gene set for vascular plants of 4,223 genes. Strikingly, the sacred lotus has 16 COG2132 multi-copper oxidase family proteins with root-specific expressionthese are involved in root meristem phosphate starvation, reflecting adaptation to limited nutrient availability in an aquatic environment.CONCLUSIONS:The slow nucleotide substitution rate makes the sacred lotus a better resource than the current standard, grape, for reconstructing the pan-eudicot genome, and should therefore accelerate comparative analysis between eudicots and monocots.

Testo completoAbstract (sommario):
Em áreas de várzeas, os rizóbios podem formar nódulos em leguminosas hibernais, adaptadas a condições de estresse hídrico, fixar nitrogênio, e colonizar as plantas de arroz, em sistema de rotação. Recentes estudos têm mostrado que os rizóbios podem colonizar raízes, caules e folhas de gramíneas, como o arroz, promovendo o crescimento da planta. A produção de fito-hormônios, principalmente ácido indol acético (AIA), é possivelmente o principal mecanismo de promoção de crescimento de arroz por rizóbios. Os objetivos deste trabalho foram estudar a resistência da simbiose entre rizóbios e Lotus a alagamento e deficiência hídrica; verificar a resposta de diferentes cultivares de arroz à inoculação com rizóbios; avaliar a interação entre a adubação nitrogenada e a promoção de crescimento por rizóbios em arroz; estudar o padrão de colonização de plantas de arroz e leguminosas por rizóbios e estudar geneticamente a biossíntese de auxinas por rizóbios. Foram realizados vários experimentos, em casa de vegetação e em laboratório, com plantas das espécies de leguminosas L. corniculatus (variedade São Gabriel) e L.uliginosus (variedade Maku) e com plantas arroz, inoculadas com diferentes rizóbios. As plantas de L.uliginosus toleraram o alagamento, mostrando potencial para utilização em áreas de várzea, em rotação com arroz. Entre as cultivares de arroz testadas, IRGA 424 mostrou-se mais responsiva à inoculação com rizóbios. A inoculação estimulou o crescimento das plantas e este incremento foi proporcional às doses de nitrogênio aplicado. Além disso, a inoculação com rizóbios permitiu maior eficiência no uso do nitrogênio absorvido do solo. A marcação dos rizóbios com o gene Gus permitiu confirmar a colonização em arroz. Os rizóbios testados são capazes de produzir AIA e há indícios de que a biosíntese ocorra pela rota do indol-3-acetonitrilo (IAN).In lowland areas, the rhizobia can form nodules in legumes, when adapted to conditions of water stress, fix nitrogen and colonize the rice plants in rotation. Recent studies have shown that rhizobia can colonize roots, stems and leaves of grasses, such as rice, promoting plant growth. The production of phytohormones, mainly indole acetic acid (IAA) is possibly the main mechanism of growth promotion of rice by rhizobia. The objectives were to study the resistance of the symbiosis between rhizobia and Lotus to flooding and drought; check the response of different rice cultivars to inoculation with rhizobia and to evaluate the interaction between nitrogen and the promotion of growth by indigenous rice; to study the colonization pattern of rice plants by rhizobia and legumes and to study genetically the biosynthesis of auxin by rhizobia. Several experiments were conducted in the greenhouse and laboratory, with plants of the legume species L. corniculatus (var. São Gabriel) and L.uliginosus (var. Maku) and rice plants inoculated with different rhizobia. L.uliginosus plants tolerate flooding, showing potential for their use in floodplain areas, in rotation with rice. Among the rice cultivars tested, IRGA424 proved to be more responsive to inoculation with rhizobia. Inoculation with rhizobia tested stimulated the growth of plants, and this increase was proportional to the doses of nitrogen applied. Furthermore, inoculation with rhizobia allowed more efficient use of nitrogen absorbed from the soil. The marking of rhizobia with the Gus gene, confirmed the colonization of rice. The rhizobia tested are able to produce IAA, and there is evidence that the biosynthesis occurs by the route of indole-3- acetonitrile (IAN).
