Abstract:
O mutualismo entre formigas e plantas está entre as interações mais bem estudadas. Seu estudo vem sugerindo e testando hipóteses ecológicas e evolucionárias aplicáveis a muitas outras formas de mutualismo. A cada ano relações mais especializadas entre formigas e plantas são descobertas. Entre estas relações podemos mencionar a obtenção de abrigo e/ou alimento pela formiga, que implica no fornecimento de proteção a planta contra herbivoria, dispersão de suas sementes e, até, polinização de suas flores. Nesta revisão são discutidos os tipos de interações mutualísticas entre formigas e plantas existentes. Mutualistics interactions between ants and plants Abstract. The mutualism between ant and plants is the one of the more studied ecological relationships, and these studies have been suggesting and testing ecological and evolutionary hypothesis that can be applied to many other kinds of mutualism. Each year more specialized mutualism relationships between ants and plants are discovered. Among these relations we can mention the obtaining of shelter and / or food by the ant, witch implies in providing plant protection against herbivory, dispersal of seeds and even pollination of their flowers. In this review are discussed mutualistics types of interactions between ants and existing plants.

Abstract:
A utilização das plantas para fins medicinais remota à antiguidade, entretanto com o avanço da medicina e da indústria farmacêutica, acentuou-se o uso de medicamentos industrializados, fato este que pode refletir na diminuição do conhecimento e uso das plantas medicinais na atualidade. E buscando-se compreender as percepções de estudantes sobre as plantas medicinais, o objetivo principal deste trabalho foi realizar um levantamento de dados sobre a diversidade de conhecimento de plantas medicinais dos alunos do Ensino Médio de uma escola pública do estado do Amapá. Realizando no referido processo intervenções pedagógicas para que os estudantes aprendessem aspectos etnobotânicos e a sua importância para a sociedade, através da criação de murais e manuseio de jogos didáticos. E para a avaliação da diversidade de saberes sobre plantas medicinais, foi utilizado um questionário semiestruturado com questões abertas e fechadas. Dentre as espécies de plantas citadas, as famílias botânicas mais presentes foram Lamiaceae, Asteraceae, Fabaceae, Malvaceae, Myrtaceae, Rutaceae. Os resultados obtidos apontam que 61,19% (N=41) das famílias dos alunos fazem uso de pelo menos alguma planta medicinal, e que 78,33% (N=47) dos estudantes afirmaram que os seus conhecimentos sobre as plantas medicinais são oriundos do conhecimento tradicional familiar. Através do presente estudo, foi possível constatar que mesmo com a expressiva utilização dos medicamentos industrializados, as plantas medicinais ainda são empregadas no tratamento de diversas enfermidades. Também pode-se inferir que para os alunos pesquisados, a tradicionalidade é um fator relevante para o repasse dos saberes sobre as plantas medicinais. Palavras-chave: Botânica. Plantas Medicinais. Tradição. AbstractUsing plants to medicinal goals recalls antiquity, however, combined to medicine and pharmaceutical industry advance, the use of industrialized drugs has accentuated, this fact may reverberate in actually knowledge and use of the medicinal plants’ decrement. When searching to comprehend the students’ perception around medicinal plants, this research’s main objective was to provide a data survey about students’ medicinal plants knowledge diversity, the work was made in a public high school in state of Amapá. Accomplished in the referred pedagogical intervention’s process to facilitate students’ ethnobotanical learning aspects and its relevance to society by creating murals and handling didactic games. To evaluate medicinal plants’ knowledge diversity, a semi-structured questionnaire with open and closed questions was applied. Among the cited plants species, the more present botanical families were Lamiaceae, Asteraceae, Fabaceae, Malvaceae, Myrtaceae, Rutaceae. The obtained results point that 61,19% (N=41) of the students’ families uses at least one medicinal plant, and 78,33% (N=47) of the students affirmed that their knowledge about plants comes from familiar traditional knowledge. Athwart this work, it was possible to verify that even with expressive industrialized drugs using, the medicinal plants are still used in the treatment of various diseases. As well, it can be inferred that to the researched students, traditionally is an important factor in passing along medicinal plants’ knowledge. Keywords: Botanical. Medicinal Plants. Tradition.

Abstract:
Flora of Turkey, which constitutes an important part of Turkey of biological diversity, ranks first among European countries. Flora of Turkey first among other countries in the world in terms of its endemism rate. Mersin province, which is located in the Mediterranean region, which is the richest region of Turkey concerning endemism, forms an important part of our country's flora and the Mediterranean in terms of floristic. The endemism rate of flora of Mersin province is approximately 23%. Today, when urbanization is increasing and the concentration in rural areas decreases, natural ingredients and plants are increasingly included in city life. For this reason, big cities and cities such as Mersin are trying to be integrated with nature or to include nature and its ingredients in city life. Unfortunately, most of the plants that are tried to be included in city life are not natural plants of our country but are mainly exotic dicotyledon ornamental plants of foreign origin. Some of these species are invasive and appear to threaten the natural ecosystem. For this reason, it is important in many aspects to include the species with natural distribution in Mersin to the landscape areas and urban ecosystem. Therefore, the natural ecosystem will not be damaged therewithal aesthetically valuable species can be considered ornamental plants. In this context, the spread of the species suggested in our study only in our country (and some only in Mersin) is of great importance in bringing these species to the ornamental plant sector. In this study, some of the dicotyl endemic plant taxa with ornamental plant potential were identified, and photographs of these taxa were presented. Thirty different endemic taxa belonging to 13 different dicotyl families identified are listed. It is seen that the endemic taxa we propose are not very aesthetically different from the taxa currently used in the landscape, and even some taxa are more striking than some exotic taxa evaluated in the landscape. In addition, the proposed list includes taxa with medical importance in the landscape and endemic taxa that can also be considered as honey plants, as well as ground cover and hedge plants. We anticipate that these taxa, which are the elements of the natural vegetation of Mersin, can be transferred to urban areas by taking inspiration from nature and prevent biological, ecological, economic, and even pathological problems caused by a significant part of exotic species.

Whether you are beginning a new landscape or renovating an existing one, planning ahead can prevent many problems. The majority of maintenance requirements and plant problems result from either selecting the wrong kind of plant for a location or planting an inferior specimen of the selected plant type. In other words, there are two decisions to be made: ▪ What species, or kind, of tree are you going to buy — an oak, pine, mesquite, or acacia? ▪ Assuming you decide on an oak, which one in the row of oaks at the nursery are you going to buy? The first decision is called Plant Selection and the second is Selecting Plants. Our goal is to install the right plant in the right place. This publication will cover the factors involved in making good decisions to achieve this goal.

Geographically, Arizona can be divided roughly into four areas, southwest, central, southeast, and northern. These regions correspond with four climatic zones, allowing a large and diverse number of plants to be grown for landscaping purposes. But, interestingly, in this desert environment many of the parasitic diseases in landscape plants are caused by a limited number of plant pathogens. This publication discusses some of those diseases that are sufficiently important to the urban plants in all areas Arizona.

Resumo: O presente trabalho teve como objetivo estudar ontogenética e morfologicamente a flor e o fruto em representantes de Bignoniaceae no intuito de verificar se ocorrem padrões no desenvolvimento do ovário bem como o modo de formação do septo e placentas e a forma de compressão do fruto nesta família. Foram realizados estudos ontogenéticos com abordagens anatômicas e de Microscopia Eletrônica de Varredura em gemas florais, botões florais, flores e frutos de representantes selecionados de acordo com atributos morfológicos de interesse taxonômico como o tipo de fruto (indeiscente/deiscente), deiscência deste em relação à coluna seminífera (paralela/perpendicular), tipo de coluna seminífera e em Jacaranda, um representante de cada seção. As espécies estudadas foram: Cybistax antisyphilitica (Mart.) Mart., Jacaranda mimosifolia D. Don (seção Jacaranda) e Jacaranda simplicifolia K. Schum. ex Bureau & K. Schum. (seção Dilobos), Digomphia laurifolia Benth. (Tecomeae), Arrabidaea brachypoda Bureau (Bignonieae) e Parmentiera cereifera Seem. (Crescentieae). Efetuou-se o estudo morfológico das espécies de Jacaranda e de Digomphia nativas do Brasil, com intuito de obter caracteres diagnósticos com enfoque em Jacaranda que apresenta espécies muito parecidas, de difícil posicionamento taxonômico. Verificou-se que o surgimento dos primórdios de filomas florais ocorre centripetamente, de forma sincrônica ou assincrônica. Os dois carpelos são ascidiados e originam-se na região central do domo, podendo esta se tornar côncava antes da iniciação dos carpelos. O septo pode estar presente desde os estádios iniciais do desenvolvimento ou surgir posteriormente. Através do estudo anatômico, verificou-se que em todas as espécies analisadas os primeiros feixes vasculares a se formarem no ovário são os dorsais, seguidos dos ventrais. Ocorrem quatro placentas, nas quais os óvulos se desenvolvem da região central próxima ao tecido transmissor para as regiões periféricas do septo, de forma basípeta ou acrópeta, variando em número de fileiras e óvulos conforme as espécies. Os óvulos são unitegumentados e anátropos. O estaminódio, mesmo que vestigial, desenvolve-se mais rapidamente que as anteras nos estádios ontogenéticos iniciais. No desenvolvimento do fruto, as maiores modificações ocorrem na região mediana do pericarpo jovem, junto aos feixes vasculares laterais, onde surgem novos feixes e fibras orientadas em vários sentidos. Registrou-se a presença de um replo em A. brachypoda, constituído por um feixe vascular lateral no pericarpo, rico em fibras e adjacências da coluna seminífera. Em Jacaranda, pode-se fazer as seguintes inferências: a Seção Dilobos apresenta plantas com hábito arbustivo ou arbóreo, com as folhas são bipinadas na maioria das árvores e pinadas nos arbustos, exceto em J. simplicifolia, que é um arbusto com folhas simples. Na Seção Jacaranda, a maioria das espécies é arbórea, com folhas bipinadas e as inflorescências são mais complexas. As espécies arbóreas de Jacaranda com folhas bipinadas e anteras monotecas possuem os frutos lenhosos, enquanto que os frutos sublenhosos a cartáceos estão dentre as espécies arbustivas e xilopodíferas deste gênero. Digomphia compartilha com Jacaranda caracteres morfológicos como a forma de compressão do fruto, deiscência perpendicular ao septo e estaminódio alongado com tricomas glandulares. A disposição dos feixes vasculares no ovário e no fruto é característica destes dois gêneros diferindo dos demais gêneros de Bignoniaceae aqui estudados
Abstract: This contribution involves the study on both, morphological and ontogenetic grounds of flower and fruit early development within representative species of Bignoniaceae. Emphasis is given to possible patterns of ovary, placentae, and septum development, as well as on fruit shape and compression. Anatomical and SEM studies were performed on floral primordia, floral buds, flowers and fruits of morphologically and taxonomically representative species. Morphological features of taxonomic relevance (type of fruits and dehiscence; type of seminal axis, etc). The studied species were Cybistax antisyphilitica (Mart.) Mart., Jacaranda mimosifolia D. Don (section Jacaranda), J. simplicifolia K. Schum. ex Bureau & K. Schum. (section Dilobos), Digomphia laurifolia Benth. (Tecomeae), Arrabidaea brachypoda Bureau (Bignonieae) and Parmentiera cereifera Seem. (Crescentieae). Complementary morphological studies were performed on native Brazilian species of Jacaranda and Digomphia. These studies were mainly focused on Jacaranda, a genus with remarkable taxonomic problems and were aimed to assemble sets of diagnostic characters for species of difficult identification. The arising of floral primordia is centripetal, the development of the primordia being synchronic or asynchronic. The two ascidiate carpels arise at the dome¿s center. This dome¿s central region may turn concave prior to carpel initiation. The septum may or may not be present at earliest developmental stages. At the ovary, the dorsal vascular bundles develop first, followed by the ventral ones. There are four placentae and the ovules develop from the central region next to the transmitting tissue, toward septum¿s peripheral region; in a basipetal to acropetal way. The number of ovules and series varies according to the species. The ovules are unitegmic and anatropous. The staminode, even in species where it is vestigial, develops faster than functional anthers during the earlier developmental stages. During fruit development, most significant modifications involve the median region of the young pericarp; where a number of variously arranged vascular bundles and fibers appear near the vascular bundles. The tissue originating the line of fruit dehiscence appears soon after the ovules are fertilized. A replum was recorded in A. brachypoda. This replum consists of a fiber-rich central vascular bundle, part of the pericarp and part of the seminal axis. Considering Jacaranda, the following inferences can be done: In its current delimitation, section Dilobos includes shrubs or trees. Most trees display bipinnate leaves. Conversely, shrubs show pinnate leaves. Remarkably, one species within this section (J. simplicifolia) is a shrub with simple leaves. Within the section Jacaranda, most species are trees with bipinnate leaves. The inflorescences are more complex in this section. Arboreal, monotecic species with bipinnate leaves display lignified fruits. Conversely, coriaceous fruits are restricted to the shrubby or xylopodiferous species. Digomphia shares a number of morphological features with Jacaranda, such as fruit shape, compression type and dehiscence, presence of an elongate staminodium covered with glandular trichomes and a characteristic arrangement of ovary and fruit vascular bundles. This latter feature is quite different in the other studied Bignoniaceae genera

AbstractThe ecosystem of the earth is fascinating and intricate. The interactions that occur in the soil affect its characteristics as a substrate for development and activity of soil microorganisms and plants. The majority of terrestrial plants have a symbiotic, mutually beneficial interaction with the soil fungi known as arbuscular mycorrhizal fungi (AMF). These microorganisms expand the root’s absorption region, which improves the plant’s ability to absorb nutrients. The symbiont gets plant carbohydrates in return for accomplishing its life cycle. Additionally, AMF aids in the adaptation of plants to biotic and abiotic challenges including salt, drought, extremely high or low temperatures, heavy metals, diseases and infections. AMF are constantly interacting with ample variety of microbes, including endo-bacteria, rhizobacteria that encourage plant growth and mycorrhiza helper bacteria, plant parasitic nematodes, fungi and other microbes inhabiting the rhizosphere and hyphosphere. Their interactions may be of utmost significance and might affect agriculture. The present chapter summarizes the main microbial community groups and their interaction with AMF in the rhizosphere and hyphosphere along with the advantageous effects of AMF on plants.

Abstract:
While much of contemporary architectural discourse around plants tends to focus on their aesthetic aspects, origins, and potential uses—such as to provide ornament, drought- resistance and/or cooling, etc.—self-seeded plants, weeds and other undesirables tend to be less of a direct subject of interest and object of study within the discipline.This paper proposes an alternative relationship between architecture and plants, in which urban and self-seeded flora are used as forensic material and studied as evidence of urban change, spatial politics and movements of people, ideas, and construction materials. For example, it looks at seeds traveling with construction materials, or under trains, as well as plants resurfacing as a consequence of bulldozed or demolished sites. The research argues that plants, rather than simply a soft landscape material counterpoint to the concrete reality of building, can be used to study the resilience of landscapes and uncover site-specific histories. Specifically, the paper introduces a series of case studies by describing participatory workshops hosted in Canada, the United States, and Germany developing a methodology for fieldwork, community engagement, and oral history through carefully investigating a chosen site and its weeds. The methodology also serves to question the so-called“vacant” and “abandoned” nature of the chosen site within the larger context & discourse about public revitalization and other gentrification endeavors. By reframing weeds as valid and worthy of interest, this paper contests the devitalized or under-vitalized nature of chosen sites by opening conversations around social, public, and environmental interactions at large. Ultimately, this presentation also explores a range of discursive models to complexify revitalization discourse, articulating a nascent model for public engagement with architecture and site-specific histories through urban botany.

Lindow, Steven, Isaac Barash, and Shulamit Manulis. Relationship of Genes Conferring Epiphytic Fitness and Internal Multiplication in Plants in Erwinia herbicola. United States Department of Agriculture, July 2000. http://dx.doi.org/10.32747/2000.7573065.bard.

Full text
Abstract:
Most bacterial plant pathogens colonize the surface of healthy plants as epiphytes before colonizing internally and initiating disease. The epiphytic phase of these pathogens is thus an important aspect of their epidemiology and a stage at which chemical and biological control is aimed. However, little is known of the genes and phenotypes that contribute to the ability of bacteria to grow on leaves and survive the variable physical environment in this habitat. In addition, while genes such as hrp awr and others which confer pathogenicity and in planta growth ability have been described, their contribution to other aspects of bacterial epidemiology such as epiphytic fitness have not been addressed. We hypothesized that bacterial genes conferring virulence or pathogenicity to plants also contribute to the epiphytic fitness of these bacteria and that many of these genes are preferentially located on plasmids. We addressed these hypotheses by independently identifying genes that contribute to epiphytic fitness, in planta growth, virulence and pathogenicity in the phytopathogenic bacterium Erwinia herbicola pv gypsophilae which causes gall formation on gypsophila. This species is highly epiphytically fit and has acquired a plasmid (pPATH) that contains numerous pathogenicity and virulence determinants, which we have found to also contribute to epiphytic fitness. We performed saturation transposon mutagenesis on pPATH as well as of the chromosome of E.h. gypsophilae, and identified mutants with reduced ability to grow in plants and/or cause disease symptoms, and through a novel competition assay, identified mutants less able to grow or survive on leaves. The number and identity of plasmid-borne hrp genes required for virulence was determined from an analysis of pPATH mutants, and the functional role of these genes in virulence was demonstrated. Likewise, other pPATH-encoded genes involved in IAA and cytokinin biosynthesis were characterized and their pattern of transcriptional activity was determined in planta. In both cases these genes involved in virulence were found to be induced in plant apoplasts. About half of avirulent mutants in pPATH were also epiphytically unfit whereas only about 10% of chromosomal mutants that were avirulent also had reduced epiphytic fitness. About 18% of random mutants in pPATH were avirulent in contrast to only 2.5% of random chromosomal mutants. Importantly, as many as 28% of pPATH mutants had lower epiphytic fitness while only about 10% of random chromosomal mutants had lower epiphytic fitness. These results support both of our original hypotheses, and indicate that genes important in a variety of interactions with plant have been enriched on mobile plasmids such as pPATH. The results also suggest that the ability of bacteria to colonize the surface of plants and to initiate infections in the interior of plants involves many of the same traits. These traits also appear to be under strong regulatory control, being expressed in response to the plant environment in many cases. It may be possible to alter the pattern of expression of such genes by altering the chemical environment of plants either by genetic means or by additional or chemical antagonists of the plant signals. The many novel bacterial genes identified in this study that are involved in plant interactions should be useful in further understanding of bacterial plant interactions.

Full text
Abstract:
Transgenic plants expressing viral genes offer novel means of engendering resistance to those viruses. However, some viruses interact synergistically with other viruses and it is now known that transgenic plants expressing particular genes of one virus may also mediate synergy with a second virus. Thus, our specific objectives were to (1) determine if transgenic plants resistant to one virus showed synergy with another virus; (2) determine what viral sequences were essential for synergy; and (3) determine whether one of more mechanisms were involved i synergy. This project would also enable an evaluation of the risks of synergism associated with the use of such transgenic plants. The conclusion deriving from this project are as follows: - There is more than one mechanism of synergy. - The CMV 2b gene is required for synergistic interactions. - Synergy between a potyvirus and CMV can break natural resistance limiting CMV movement. - Synergy operates at two levels - increase in virus accumulation and increase in pathology - independently of each other. - Various sequences of CMV can interact with the host to alter pathogenicity and affect virus accumulation. - The effect of synergy on CMV satellite RNA accumulatio varies in different systems. - The HC-Pro gene may only function in host plant species to induce synergy. - The HC-Pro is a host range determinant of potyviruses. - Transgenic plants expressing some viral sequences showed synergy with one or more viruses. Transgenic plants expressing CMV RNA 1, PVY NIb and the TMV 30K gene all showed synergy with at least one unrelated virus. - Transgenic plants expressing some viral sequences showed interference with the infection of unrelated viruses. Transgenic plants expressing the TMV 30K, 54K and 126K genes, the PVY NIb gene, or the CMV 3a gene all showed some level of interference with the accumulation (and in some cases the pathology) of unrelated viruses. From our observations, there are agricultural implications to the above conclusions. It is apparent that before they are released commercially, transgenic plants expressing viral sequences for resistance to one virus need to be evaluated fro two properties: - Synergism to unrelated viruses that infect the same plant. Most of these evaluations can be made in the greenhouse, and many can be predicted from the known literature of viruses known to interact with each other. In other cases, where transgenic plants are being generated from new plant species, the main corresponding viruses from the same known interacting genera (e.g., potexviruses and cucumoviruses, potyviruses and cucumoviruses, tobamoviruses and potexviruses, etc.) should be evaluated. - Inhibition or enhancement of other resistance genes. Although it is unlikely that plants to be released would be transformed with HC-Pro or 2b genes, there may be other viral genes that can affect the expression of plant genes encoding resistance to other pathogens. Therefore, transgenic plants expressing viral genes to engender pathogen-derived resistance should be evaluated against a spectrum of other pathogens, to determine whether those resistance activities are still present, have been lost, or have been enhanced!

Full text
Abstract:
The possibility of extensive SCC in natural gas treatment plants is of obvious concern to the gas transmission industry. As a result, PRCI initiated a research project at Southwest Research Institute (SwRI) to investigate the SCC susceptibility of carbon steels in MEA and DEA solutions typical of amine solutions used in natural gas treatment plants. The primary objectives of the project were: to determine the parameters responsible for cracking; and to determine modifications to plant equipment an and or process chemistry that might be used to control SCC in natural gas treatment plants. This report describes the factors responsible for stress corrosion cracking (SCC) of steels in natural gas treatment plants using ethanolamine solutions to remove acid gases from natural gases; and to determine modifications to plant equipment and/or process equipment that might be used to control SCC in natural gas treatment plants.

Full text
Abstract:
The function of the 30-kilodalton movement protein (MP) of tobacco mosaic virus (TMV) is to facilitate cell-to-cell movement of viral progeny in infected plants. Our earlier findings have indicated that this protein has a direct effect on plasmodesmal function. In addition, these studies demonstrated that constitutive expression of the TMV MP gene (under the control of the CaMV 35S promoter) in transgenic tobacco plants significantly affects carbon metabolism in source leaves and alters the biomass distribution between the various plant organs. The long-term goal of the proposed research was to better understand the factors controlling carbon translocation in plants. The specific objectives were: A) To introduce into tobacco and potato plants a virally-encoded (TMV-MP) gene that affects plasmodesmal functioning and photosynthate partitioning under tissue-specific promoters. B) To introduce into tobacco and potato plants the TMV-MP gene under the control of promoters which are tightly repressed by the Tn10-encoded Tet repressor, to enable the expression of the protein by external application of tetracycline. C) To explore the mechanism by which the TMV-MP interacts with the endogenous control o~ carbon allocation. Data obtained in our previous project together with the results of this current study established that the TMV-MP has pleiotropic effects when expressed in transgenic tobacco plants. In addition to its ability to increase the plasmodesmal size exclusion limit, it alters carbohydrate metabolism in source leaves and dry matter partitioning between the various plant organs, Expression of the TMV-MP in various tissues of transgenic potato plants indicated that sugars and starch levels in source leaves are reduced below those of control plants when the TMV-MP is expressed in green tissue only. However, when the TMV-MP was expressed predominantly in PP and CC, sugar and starch levels were raised above those of control plants. Perhaps the most significant result obtained from experiments performed on transgenic potato plants was the discovery that the influence of the TMV-MP on carbohydrate allocation within source leaves was under developmental control and was exerted only during tuber development. The complexity of the mode by which the TMV-MP exerts its effect on the process of carbohydrate allocation was further demonstrated when transgenic tobacco plants were subjected to environmental stresses such as drought stress and nutrients deficiencies, Collectively, these studies indicated that the influence of the TMV-MP on carbon allocation L the result of protein-protein interaction within the source tissue. Based on these results, together with the findings that plasmodesmata potentiate the cell-to-cell trafficking of viral and endogenous proteins and nucleoproteins complexes, we developed the theme that at the whole plant level, the phloem serves as an information superhighway. Such a long-distance communication system may utilize a new class of signaling molecules (proteins and/or RNA) to co-ordinate photosynthesis and carbon/nitrogen metabolism in source leaves with the complex growth requirements of the plant under the prevailing environmental conditions. The discovery that expression of viral MP in plants can induce precise changes in carbon metabolism and photoassimilate allocation, now provide a conceptual foundation for future studies aimed at elucidating the communication network responsible for integrating photosynthetic productivity with resource allocation at the whole-plant level. Such information will surely provide an understanding of how plants coordinate the essential physiological functions performed by distantly-separated organs. Identification of the proteins involved in mediating and controlling cell-to-cell transport, especially at the companion cell-sieve element boundary, will provide an important first step towards achieving this goal.

Marinkovic, Catalina, and Adrien Vogt-Schilb. Is Energy Planning Consistent with Climate Goals? Assessing Future Emissions from Power Plants in Latin America and the Caribbean. Inter-American Development Bank, October 2023. http://dx.doi.org/10.18235/0005183.

Full text
Abstract:
At least ten Latin American and Caribbean countries have pledged to achieve carbon neutrality. Has electricity planning in the region evolved towards reaching these goals? We compare power generation capacity in 2023 to announced plans in 2019. We then estimate committed emissions from existing and planned power plants that is emissions that would result from the normal operations of these plants during their typical lifetime and compare them to emissions from power generation in published IPCC scenarios. We find that fossil fuel planned capacity has decreased by 47% since 2019, mainly due to the cancellation of 50% of coal and 40% of gas projects, compared to only 32% of renewable energy projects. But existing plants in the region will emit 6.7 GtCO2 during their lifespan, and if all planned plants are built, they will add 4.9 GtCO2, totaling 11.6 GtCO2, exceeding median carbon budgets for 1.5 and 2C-consistent IPCC pathways (2.3 and 4.3 GtCO2). Natural gas power plants are the largest contributor to existing (62%) and planned (75%) emissions (versus 24% and 23% for coal). We evaluate emissions reduction strategies to achieve carbon budgets. Assuming no new coal plants comes into operation, announced gas and oil projects are canceled at the same rate as in the past four years, all fossil fueled plant lifetimes are reduced by 10 years, and all new natural gas displaces existing coal, committed emissions fall by 59%, almost meeting the 2C budget, but still twice as large as the median 1.5C budget. Our results suggest that while progress is being made, energy planning in the region is not yet consistent with global climate goals as reflected by the IPCC scenario database.

Full text
Abstract:
While the United States has roughly doubled its investments in clean energy over the past 10 years, the power grid is still predominantly reliant on natural gas; gas plants provided 43 percent of generating capacity in 2022. This heavy reliance on gas plants, coupled with an assumption that gas plants are more reliable than they actually are, is a vulnerability for the power grid and for consumers. As recent evidence has shown, the US fleet of gas plants is susceptible to large-scale failures during extreme weather. For example, recent winter storms in Texas and the Southeast knocked unprecedented portions of the fleet offline, ultimately leading to rolling blackouts for millions of people. Heat waves and droughts have also significantly interfered with gas plant operations. As the impacts of climate change intensify, extreme weather events are becoming more frequent and more severe, increasing the threat to gas plants and, in turn, to the reliability of the power grid. Given these growing challenges, we must reassess the role of this resource in ensuring grid reliability.

Full text
Abstract:
Repair of DNA breaks is an essential function in plant cells as well as a crucial step in addition of modified DNA to plant cells. In addition, our inability to introduce modified DNA to its appropriate locus in the plant genome remains an important hurdle in genetically engineering crop species.We have taken a combined forward and reverse genetics approach to examining DNA double strand break repair in plants, focusing primarily on nonhomologous DNA end-joining. The forward approach utilizes a gamma-plantlet assay (miniature plants that are metabolically active but do not undergo cell division, due to cell cycle arrest) and has resulted in identification of five Arabidopsis mutants, including a new one defective in the homolog of the yeast RAD10 gene. The reverse genetics approach has identified knockouts of the Arabidopsis homologs for Ku80, DNA ligase 4 and Rad54 (one gene in what proves to be a gene family involved in DNA repair as well as chromatin remodeling and gene silencing)). All these mutants have phenotypic defects in DNA repair but are otherwise healthy and fertile. Additional PCR based screens are in progress to find knockouts of Ku70, Rad50, and Mre11, among others. Two DNA end-joining assays have been developed to further our screens and our ability to test candidate genes. One of these involves recovering linearized plasmids that have been added to and then rejoined in plant cells; plasmids are either recovered directly or transformed into E. coli and recovered. The products recovered from various mutant lines are then compared. The other assay involves using plant transposon excision to create DNA breaks in yeast cells and then uses the yeast cell as a system to examine those genes involved in the repair and to screen plant genes that might be involved as well. This award supported three graduate students, one in Israel and two in the U.S., as well as a technician in the U.S., and is ultimately expected to result directly in five publications and one Masters thesis.
