SHTEIN, RONEN, DAVID-PAUL KLEIN et GIDEON F. SMITH. « A new status for two varieties previously included in the southern Malagasy Kalanchoe rosei, now included in K. variifolia (Crassulaceae subfam.

Résumé :
Kalanchoe rosei (Crassulaceae subfam. Kalanchooideae) is a phyllo-bulbiliferous species endemic to southern Madagascar. Historically, two varieties, K. rosei var. seyrigii and K. rosei var. variifolia, have been recognised in K. rosei. One of the two specimens cited when K. rosei var. seyrigii was described bears much resemblance to K. peltigera. However, regardless of how K. rosei var. seyrigii was originally described, the type of the name K. rosei var. seyrigii, which determines its application, is that of the synonym it replaced, i.e., K. rosei subsp. serratifolia. The two varieties, K. rosei var. seyrigii and K. rosei var. variifolia, were originally described as subspecies and are sometimes treated at that rank, as K. rosei subsp. serratifolia and K. rosei subsp. variifolia. Kalanchoe rosei var. seyrigii and K. rosei var. variifolia are morphologically very similar and, based on reproductive morphology alone, can hardly be distinguished, which reaffirms the close relationship between them. Kalanchoe rosei is most closely related to K. peltigera, as well as to K. daigremontiana, K. laetivirens, and K. sanctula, a group of pink-flowered constitutively phyllo-bulbiliferous species from Madagascar. In contrast, K. rosei var. seyrigii and K. rosei var. variifolia rather share several morphological similarities with orange-flowered representatives included in the informal group “Suffrutescentes”, and frequently hybridise with them. Kalanchoe rosei var. variifolia is here elevated to species rank, as K. variifolia, for material hitherto treated as belonging to K. rosei var. seyrigii and K. rosei var. variifolia. Two varieties, the autonymic one and K. variifolia var. seyrigii, are recognised in K. variifolia. The typification of K. rosei subsp. variifolia and K. rosei var. seyrigii, the basionyms of K. variifolia var. variifolia and K. variifolia var. seyrigii, respectively, is clarified.

Résumé :
The identity of the Malagasy Kalanchoe rosei (Crassulaceae subfam. Kalanchooideae) is resolved, inter alia through a rigorous review and interpretation of the type of the name, as well as associated preserved and living material. Apart from the autonymic variety, K. rosei var. rosei, two further varieties were at times often recognised, i.e., K. rosei var. seyrigii and K. rosei var. variifolia, both of which are now treated in K. variifolia. However, based on a comprehensive morphological investigation, even within K. rosei var. rosei, the autonymic variety therefore, we conclude that two distinct species can be identified. The one that does not include the type of the name K. rosei is here described as K. perrieri. In addition, as shown here, K. rosei is more closely related to K. peltigera, rather than to the material here described as K. perrieri, while material of K. variifolia is more distantly related. The typification of the names K. rosei and K. bouvieri is clarified.

Résumé :
The taxonomy and nomenclature of Kalanchoe peltigera (Crassulaceae subfam. Kalanchooideae) and K. rosei var. seyrigii, a long-overlooked name published in the 1940s, are evaluated with an aim to resolve the taxonomic status and affinities of K. peltigera, which was described in the mid-2000s. In particular, the taxonomic status of K. peltigera as an accepted species is examined in detail and verified based on a comparison with other known phyllo-bulbiliferous species of Kalanchoe i.e., those species that produce bulbils on the margins of their leaf blades typically between crenations, as opposed to flori-bulbiliferous, or stoloniferous species. We show that both K. peltigera and the original description of K. rosei var. seyrigii are based on collections made of a single species from locations in close proximity in southern Madagascar. Based on an examination of living material and type specimens, as well as other herbarium accessions, of which only a limited number exist, we conclude that K. peltigera and one of the two specimens cited when K. rosei var. seyrigii was described apply to the same species. However, despite its original description, the type of the name K. rosei var. seyrigii is that of the synonym it replaced, i.e., K. rosei subsp. serratifolia, a taxon less closely related to K. peltigera, and therefore the two names are not synonymous. A morphological evaluation suggests that K. rosei is likely to be sister to K. peltigera. The name K. peltigera is neotypified as its holotype is no longer extant.

Kalanchoe torrejacqii (Crassulaceae subfam. Kalanchooideae) is described as a new phyllo-bulbiliferous species. It occurs in the Namorona River valley, near Ranomafana, southern Madagascar. Differences between K. torrejacqii and the partially sympatric K. laxiflora are discussed and the new species is contrasted with representatives of the K. rosei complex with which it shares some similarities. Kalanchoe torrejacqii is the most northern pink-flowered species among other such species that belong to the recently described K. sect. Invasores, to which K. laxiflora and representatives of the K. rosei complex also belong.

Résumé :
AbstractOur floristic work in British ancient forests resulted in a description of a frequently reported but misidentified species, Coenogonium nimisii. Its thallus is very similar to Porina rosei, but the apothecia and pycnidia correspond with C. luteum. Sterile collections are not easy to distinguish but the new species differs from P. rosei in several microscopic characters of the isidia. Coenogonium nimisii is so far known from bark and epiphytic bryophytes, rarely mossy rocks, in ancient humid forests of Great Britain and Ireland. The genus Coenogonium is poorly represented by molecular data in the GenBank database. Our preliminary results revealed distinct genetic lineages within two traditionally circumscribed species, C. luteum and C. pineti, which may represent cryptic species.

Based on morphological study and corroborated by unpublished molecular phylogenetic analyses, five grass species of high-mountain grasslands in Mexico, Central and South America, Agrostis bacillata, A. exserta, A. liebmannii, A. rosei, and A. trichodes, are transferred to Podagrostis and bring the number of species of this genus recognized in the New World to ten. The name Apera liebmannii is lectotypified and epitypified. We provide an updated genus description for Podagrostis, and updated species descriptions, images, and notes on the new combinations. The diagnostic characteristics differentiating Podagrostis from Agrostis are: a) palea that reaches from (2/3) ¾ to almost the apex of the lemma; b) florets that usually almost equal the length of the glumes or are at least ¾ the length of the glumes; c) rachilla extension present and emerging from under the base of the palea as a slender short stub (rudimentary or up to 1.4 mm long, sometimes obscure in most florets in P. rosei), smooth or scaberulous, glabrous or distally pilulose (hairs < 0.3 mm long); d) lemmas usually awnless, sometimes with a short straight awn 0.2–0.6 mm long, inserted medially or in the upper 1/3 of the lemma, not surpassing the glumes (awn well-developed, straight or geniculate and inserted in lower 1/3 of lemma, not or briefly surpassing glumes in P. rosei). We include a generic key to distinguish the species of Podagrostis from other similar genera in Latin America and a key to distinguish the species of Podagrostis now accepted as occurring in these areas.

Résumé :
AbstractRose's mountain toad Capensibufo rosei survives in a few isolated montane populations in the south-western Cape of South Africa. It comprises several cryptic species but it is uncertain whether the lineage on the Cape Peninsula is distinct. We tested the hypothesis that toads from the Peninsula form a single genetic lineage but that different breeding sites are divergent at a population level as a result of limited dispersal abilities. Directed surveys were carried out to locate breeding sites and samples obtained were analysed in a phylogenetic and population genetic framework, using two mitochondrial markers. We found toads breeding at only one of five known historical breeding sites, although one new breeding site was also recorded. No toads were observed at 15 other non-breeding localities where they were historically observed. Toads from the two active breeding sites formed a single lineage that was sufficiently distinct to be given species status. However, these were discrete at a population level, with no shared haplotypes, suggesting no gene flow between sites. One site was particularly low in genetic diversity, implying increased vulnerability to stochastic events and elevated risk of extinction. These results, coupled with the failure to locate historically known sites on the Cape Peninsula, make this newly recognized Peninsula endemic a conservation priority. Efforts should focus on the protection and expansion of the two known surviving populations and the patches of habitat upon which they rely.

Ecological, coenotic and floristic analysis of broadleaved-coniferous forests mostly corresponding to association Rhodobryo rosei – Piceetum abietis Korotkov 1986 was conducted with these bases. Releves (305) from South taiga and broadleaved-coniferous subzone were used. The analysis revealed complex syntaxonomy, bo­real-nemoral character and wide distribution ass. Rhodobryo-Piceetum from central European Russia. Ecolo­gical comparison of this association with some no­men­clature types of broadleaved-coniferous communities in East Europe was carried out. Preliminary prodromus for Euro­pean Russian mixed forests is suggested. Role of ecologi­cal, succession and regional factors was shown for dif­ferentiation of syntaxa.

Our objectives were to assess the efficacy of various plant growth regulators (PGRs) on stem elongation and branching of 11 kalanchoe (Kalanchoe) species with ornamental characteristics: beauvard’s widow’s-thrill (K. beauvardii), K. glaucescens, lavender scallops or red-leaved kalanchoe (K. fedtschenkoi), K. longiflora, chandelier plant (K. manginii), marnier’s kalanchoe (K. marnieriana), K. millotii, flower dust plant (K. pumila), K. rosei, common kalanchoe or nentabos (K. rotundifolia), and K. streptantha. Foliar spray applications of deionized water, ancymidol (15−60 ppm), benzyladenine (75−300 ppm), chlormequat chloride (750−3000 ppm), daminozide (1250−5000 ppm), ethephon (250−1000 ppm), paclobutrazol (10−40 ppm), or uniconazole (5−20 ppm) were applied 2 weeks after plants were pinched. Stem length at the time of application and 4 weeks after applications and branch number were recorded. While effective chemicals and concentrations varied widely among species, paclobutrazol and uniconazole were identified as providing broad efficacy with respect to inhibition of stem elongation across all 11 species in this study. Additionally, benzyladenine and ethephon increased the number of branches for several species.

Résumé :
The boll weevil (Anthonomus grandis Boheman) reproduces on a reported 13 species of wild host plants in North America, two in the United States and 12 in Mexico. The distributions of these plants are of economic importance to pest management and provide insight into the evolutionary history and origin of the BW. However, detailed information regarding the distributions of many of these species is lacking. In this article, we present distribution models for all of the reported significant BW host plants from Mexico and the United States using spatial distribution modelling software. Host plant distributions were divided into two groups: “eastern” and “western.” In Mexico, Hampea nutricia along the Gulf Coast was the most important of the eastern group, and the wild cottons, Gossypium aridum and Gossypium thurberi were most important in the western group. Other species of Hampea, Gossypium, and Cienfuegosia rosei have relatively restricted distributions and are of apparent minimal economic importance. Cienfuegosia drummondii is the only truly wild host in the southern United States, east of New Mexico. Factors determining potential distributions were variable and indicated that species were present in five vegetation types. Ecological and economic considerations of host plant distributions are discussed, as well as threats to host plant conservation.

Résumé :
Review of recently collected material of Eohiodon from North America suggests that there are two valid species, E. rosei (Hussakof) and E. woodroffi Wilson. Eohiodon falcatus Grande is identical to E. woodruffi in known skeletal features and nearly all meristic features and is treated as a junior synonym of the latter. The fossil genus Eohiodon Cavender differs from Hiodon Lesueur, which is known from both fossil and extant species, in numerous meristic and osteological features. The caudal skeleton in Eohiodon is nearly identical to that in Hiodon.The traditionally accepted Notopteroidei, containing Lycopteridae, Hiodontidae, and Notopteridae, is a polypheletic group. The Asian fossil family Lycopteridae is not more closely related to Hiodontidae than it is to other taxa in the Osteoglossomorpha, but is sister to all other Osteoglossomorpha. The Hiodontiformes sensu stricto, including only the family Hiodontidae, is the sister-group of the Osteoglossiformes. This family is not more closely related to notopterids than to other taxa in Osteoglossiformes. The Notopteridae are most closely related to the Mormyroidea; together they and the fossil family Ostariostomidae constitute the sister-group of the Osteoglossoidei.Fossil records of Hiodontiformes sensu stricto and Notopteroidei indicate a widespread pre-Neogene biogeographic range of these freshwater teleosts, suggesting that extinction must have been involved in the Cenozoic evolution of these two osteoglossomorph sublineages.

Three new species, Miacis rosei, Uintacyon gingerichi, and Vassacyon bowni, collected from the base of the Wasatchian North American Land Mammal Age (Wa-0), are the smallest and possibly most basal members of their respective genera, and increase from one to four the number of miacids known from this faunal zone. An upper dentition of Miacis deutschi from slightly younger (Wa-2) deposits is also described. Previously known only from lower teeth and a single M1, the specimen of M. deutschi includes the left P3-M2, alveoli for the canine, first two premolars and the last molar, as well as most of the maxilla. the new material helps fill gaps in our knowledge of the dental morphology of basal Miacidae and provides insight into the functional differences of the carnassial teeth in the diverging Uintacyon and Miacis lineages. It also provides an opportunity to further assess the hypothesis that climactic warming in the earliest Eocene resulted in evolutionary dwarfing of mammalian species; based on three criteria for identifying dwarfed species at least one of the new taxa, U. gingerichi, is consistent with this hypothesis.

Résumé :
Late Mississippian and earliest Pennsylvanian trilobite faunas of North America are dominated by the Paladin and Kaskia clades. Phylogenetic analysis of middle Carboniferous species of these clades demonstrates the close ancestral relationship between these groups. The Kaskia clade consists of eight species: K. chesterensis Weller, 1936, K. osagensis (Cisne, 1967), K. longispina (Strong, 1872), K. wilsoni (Walter, 1924), K. genevievensis (Walter, 1924), K. rosei (Cisne, 1967), K. gersnai n. sp., and K. rollinsi n. sp. Kaskia Weller, 1936 ranges from late Osagean to middle Chesterian (early Visean-early Serpukhovian) and is restricted to cyclothemic shelf and nearshore deposits. Species of Kaskia appear to have evolved in areas of shallow water and high environmental stress. The Paladin clade consists of 12 species including previously named species P. morrowensis (Mather, 1915), P. girtyianus Hahn and Hahn, 1970, P. rarus Whittington, 1954, P. helmsensis Whittington, 1954, and P. moorei (Branson, 1937). New species belonging to this clade are Paladin moorefieldensis n. sp., P. pleisiomorphus n. sp., P. imoensis n. sp., P. mangeri n. sp., and P. wapanukaensis n. sp. This group ranges from the early Chesterian to early Morrowan (late Viseanlate Bashkirian). Species of Paladin appear to be confined to outer shelf shelf-edge and off-shelf facies where presumably deeper water environments existed. This is manifested in their paleogeographic distribution, which is paleoenvironmentally controlled.

Résumé :
Without a doubt, roses have been and continue to be an important landscape and greenhouse plant. From the early records, dating back to Egyptian, Roman, and Greek times, roses have played an important societal role. Early attempts at growing roses in Prairie Canada were frequently unsuccessful. The extreme cold in winter, where temperatures of –30 to –40 °C are common, and droughts and heat in the summer greatly reduced the range of plant material, including roses that could be grown. As a result, the Morden Research Centre, part of Agriculture and Agri-Food Canada's Research Branch in southern Manitoba, initiated a series of projects on the development of hardy landscape plants including roses. Since1929, we have introduced over 130 new landscape plant cultivars to the nursery trade, including 18 cultivars of roses. One of the keys to the success of the program was the incorporation of cold tolerance originally obtained from Rosa arkansana, a prairie native. This has led to the development of the `Parkland' rose series. This group of plants flowers repeatedly, are hardy to USDA zone 3, root from softwood cuttings, and are available in a variety of colors. Highlights of these will be presented. More recently, emphasis has been placed on developing breeding strategies to improve disease resistance. Major diseases affecting roses include black spot (Diplocarpon rosea), powdery mildew (Sphaerotheca pannosa), and rust (Phragmidium sp.). Details of the current breeding protocols will be outlined as well as results from a series of trials established to elucidate the influence of environment and genotype on disease expression. Cooperative disease monitoring trials (Canada and Sweden) were established and results will be presented.

Résumé :
Our objectives in this study were to identify the flowering response of Kalanchoe spp. to photoperiodic treatments and characterize flowering and vegetative characteristics of flowering plants. Twenty vegetatively propagated Kalanchoe spp. were grown under one of four photoperiodic treatments: 1) short days (SD; 8-h photoperiod) for 16 weeks; 2) night interruption lighting (NI; 2000 to 0200 hr) for 16 weeks; 3) SD for 8 weeks then transferred to NI for 8 weeks; or 4) NI for 8 weeks then transferred to SD for 8 weeks. Kalanchoe beauvardii, K. behariensis, K. fedtschenkoi, K. longiflora, K. marmorata, K. marnieriana, K. streptantha, K. tomentosa, and K. vigueridoi did not flower under any treatment. Kalanchoe laetivirens and K. rosei had minimal flowering when exposed to NI followed by SD, whereas K. pumila had minimal flowering when exposed to SD followed by NI. Kalanchoe glaucescens, K. laciniata, K. manginii, K. nyikae, K. rotundifolia, K. uniflora, and K. velutina flowered when exposed to SD for 8 or 16 weeks, and node number below the inflorescence and days to first open flower for these species increased when NI preceded SD. Kalanchoe millotii flowered under a 16-week SD treatment only. No plants flowered when grown under only NI. We classified K. glaucescens, K. laciniata, K. manginii, K. millotii, K. nyikae, K. rotundifolia, K. uniflora, and K. velutina as obligate SD plants. Flower diameter, total flower number, total color index, shoot length, branch number, and leaf length and width varied among species. Based on these ornamental characteristics, we identified K. glaucescens, K. laciniata, K. manginii, K. nyikae, K. uniflora, and K. velutina as potential ornamental flowering potted plants.

Résumé :
Although roses have long been an important landscape plant, there is a growing interest in the use of low-maintenance roses that do not require heavy pruning or spraying. Poulsen Roser Pacific, Inc. of Central Point, Oregon, provided three plants of 48 cultivars for a trial in Stillwater, Oklahoma. The plants were produced in Oregon by grafting cultivars on seedling Rosa multiflora rootstock. Two-year-old plants were shipped bare-root to Stillwater, Oklahoma where they were planted in the field in early April, 2001. The plants were placed in three randomized complete blocks (rows) with 90 cm spacing between plants and 240 cm spacing between rows. The plants were drip irrigated as needed. During the 2002 growing season the roses were evaluated weekly for flower number, black spot, and overall quality. Four rose cultivars from Poulsen's Town and Country® series of landscape roses, Martha's Vineyard™ (`Poulans'), followed by Madison™ (`Poulrijk'), Kent™ (`Poulcov'), and Tumbling Waters™ (`Poultumb'), had the highest average flower number. Martha's Vineyard™, Kent™, and Tumbling Waters™ also rated highest among the cultivars tested for overall plant quality and black spot resistance. Other roses in the top grouping (Waller-Duncan K-ratio t test) for black spot resistance and overall quality were: Ragtime™ (`Poultieme', a climber from the Courtyard® series), Sophia Renaissance® (`Poulen002', Renaissance® series), Nashville™ (`Poulbico', Town and Country® series), Redwood™ (`Poultry', National Parks® series), Julia Renaissance® (`Poulheart', Renaissance® series), Santa Barbara™ (`Pouloesy', Town and Country® series), and Everglades™ (`Poulege', National Parks® series).

If one can still recognize elements of (literary) fairy tales in the original agitative text, these are largely obliterated in the translation. The fairy tales lose the elements that marked them as fairy tales. In East Germany, the early Soviet fairy tale criticism, which had lost its sharpness at the Soviet Writers’ Congress in 1934, is taken over, while in Czechoslovakia it is still represented only by orthodox criticism.

Résumé :
Introduction. Longitudinal studies of human activity and metabolism revealed various anti-inflammatory, immunomodulatory, antistress, antioxidant, and adaptogenic properties of such secondary plant metabolites as phenolic compounds and pigments. Human cells cannot synthesize these compounds. Therefore, food biotechnology requires new data on the photosynthetic potential of plants with good functional prospects. The research objective was to study the qualitative and quantitative profile of biologically active compounds of Rhodiola rosea L. harvested from various plant communities in order to define the potential of their extracts and minor compounds for food technologies. Study objects and methods. The research featured three communities of Rhodiola rosea L. originally located in ecologically and geographically different habitats. They were introduced into Kuzbass from the Kuznetsk Alatau, Gorny Altai, and the Tunka alpine tundra belt in Buryatia. The experiment began in 2018, when the rhizomes were dissected into equal shares of 40–42 g and placed in a medicinal plant nursery. The methods of high-performance liquid (HPLC) and thin-layer (TLC) chromatography were used to study the biologically active substances in the plant biomass. The photosynthetic pigments were detected using the spectrophotometric method. The obtained data underwent a statistical analysis based on Statistica 6.0 software. Results and discussion. The sample from the Gorny Altai community revealed twelve biologically active substances. Its rhizomes appeared rich in gallic acid with the maximum content (mg/g) of 10.26 ± 2.31, rosein (20.45 ± 3.46), daphneticin (13.80 ± 2.30), and salidroside (28.16 ± 2.27). The tops demonstrated the maximum content (mg/g) of astragaline (38.94 ± 2.21), tricine (13.07 ± 0.72), tricine-5-O-β-D-glucopyranoside (35.25 ± 1.66), tricine-7-O-β-D-glucopyranoside (30.23 ± 1.45), and tyrosol (21.80 ± 1.21). The Kuznetsk Alatau sample proved to possess five biologically active substances. Its rhizomes had the maximum content (mg/g) of rosavin (16.89 ± 2.11) and salidroside (14.35 ± 2.52). The sample obtained from the Tunka ridge in Buryatia had six biologically active substances with the maximum content (mg/g) of rosavin (20.72 ± 2.11), methylgalate (39.00 ± 1.05), and cinnamaldehyde (10.15 ± 1.93) in the rhizomes. The top biomass of Rhodiola rosea L. accumulated about 0.333 mg/g of chlorophylls and synthesized 0.109 mg/g of carotenoids on average. The research established the correlation coefficients between the content of photosynthetic components with morphometric characteristics, including two positive dependences between the content of carotenoids and the number of leaves (r = 0.89 ± 0.09) and the content of carotenoids and shoot length (r = 0.96 ± 0.22). Conclusion. The samples of Rhodiola rosea L. demonstrated a good biotechnological potential for medicine and food industry. The Kuznetsk Alatau plant community proved rich in rosavin, salidroside, and methyl gallate. The Gorny Altai samples revealed high content of salidroside, gallic acid, daphnetitsin, and rosein. The Tunka samples appeared to synthesize a lot of methyl gallate, rosavin, and cinnamaldehyde. In addition, the top biomass of the Altai sample proved rich in tricine and its derivatives, astragaline and tyrosol. The research also established the possibility of commercial extraction of photosynthetic pigments from the top biomass of Rhodiola rosea L. for functional food production.

Résumé :
The ipê belongs to the Bignoniaceae Family, which has approximately 120 genera and 800 species, the largest genus belonging to this family is Tabebuia, found with great diversity in South America, due to its tropical and subtropical climate. Due to the enormous variety of plants of this genus, it was necessary to create a division based on their specific characteristics: Tabebuia, Handroanthus (exclusive to represent the species existing in Brazil) and Roseodendron. This work sought to gather information on the antimicrobial and phytochemical activity of substances found in the Bignoniaceae family, respectively, in the genera: Tabebuia rosea-ipê rosa; Handroanthus impetiginosus- purple ipe; Handroanthus albus-ipe yellow; Tabebuia roseo-alba-ipê (white) through the extraction of lapachol. With the present study, it is possible to evidence the great benefits arising from the extracts of ipês. However, the scarcity of studies of this type is clear, this fact makes it difficult to disseminate proof of the beneficial effects of ipês.

Résumé :
Abstract Background Primary pituitary lymphoma (PPL) in immunocompetent individuals represents a distinct and rare clinical entity. Clinical Case A 49-year-old menopausal woman with past medical history of hypertension and obesity who presented to the emergency room with sudden onset loss of vision in her right eye with blurriness on the left. She had been having intermittent headaches and flu-like symptoms over the 2 days preceding her presentation. Her BP was 179/116 mmHg, initial basic metabolic profile was normal, and head CT showed hemorrhage into a bilobed sellar and suprasellar mass measuring 2.2×2.2×3.3 cm. On ophthalmic exam, the right eye showed near-complete visual field loss with some residual island of vision superotemporally while left eye showed temporal hemianopsia. Initial endocrine workup was notable for a normal cortisol 15.9 (ref 2-20) ug/dL and normal prolactin; low-normal TSH 0.73 (ref 0.2-4.2) uIU/mL; low free T4 0.3 (ref 0.9-1.7) ng/dL; low FSH, LH, and IGF-1. She received a pituitary MRI showing hemorrhagic pituitary macroadenoma with significant upward bowing of the optic chiasm and infiltration into the cavernous sinuses. The patient developed diabetes insipidus (DI) before being taken to the operating room for transsphenoidal surgery with debulking and biopsy. Postoperatively and while waiting for pathology results, she developed panhypopituitarism and was being treated with hydrocortisone, levothyroxine, and desmopressin. Her pathology was consistent with diffuse large B-cell lymphoma (DLBCL) of non-germinal center type. She had a complete hematologic workup including whole body PET-CT showing sellar and suprasellar fluorodeoxyglucose avid disease without evidence of disease elsewhere in the head, neck, and torso which confirmed the diagnosis of PPL. The patient was started on chemotherapy using R-CHOP (rituximab, cyclophosphamide, hydroxyadriamycine, vincristine, and prednisone) with high-dose methotrexate. Following the first chemotherapy treatment cycle, she had a modest improvement in her vision; however, her DI was permanent. Conclusion This case demonstrates that PPL can present with pituitary apoplexy and can result in panhypopituitarism and permanent DI. Individuals with this condition require a multidisciplinary care team including endocrinology, neurosurgery, hematology, and ophthalmology. References A Giustina, M Gola, M Doga, E A Rosei.

Roses have an indisputable leading role in private gardens. They also appear in public areas. They are very interesting plants for public urban areas because they represent aesthetic, ecological, tehnical and sociological potential. In public areas varietes are selected according to various criteria such as resistance to heat, low temperatures an drought, repetitive flowering and ease of maintenance. The aim of our study is to present preferences in the selection of groups of roses, their colors, types of plantings, the abudance of roses in planting and the height of individual roses on difrent subtypes of public ans semi-public green areas of the Bežigrad community, Ljubljana. The results of the study showed that the most comomn roses in urban public areas are floribundas. Dominated type of planting is a few plants together in a group. In neighborhoods and block settlements are dominated individual plants. The most common color of roses is red. In urban public areas are planted only roses up to 1 m height. In semi-public areas are also higher roses. The abudance of roses in semi-urban areas varies from 1 to over 30 roses in planting. In urban public areas are most common planting with 10 to 20 roses and those with more than 30 roses.

The Sapuangin Merapi area, Klaten Regency is a buffer village. The Sapuangin area is under the supervision of the Mount Merapi National Park Office. The Sapuangin area includes the Tegalmulyo Village area, Kemalang District, Klaten Regency. Tegalmulyo Village is located close to Mount Merapi, so this village has good natural resources, fertile soil and cool air. Local village people plant roses in fields. Every day, roses are harvested with a yield of 50 kg. Roses are sold to collectors every day. The price of roses sold is adjusted to the price of roses on the market on that day. The price of roses can change at any time according to market mechanisms. In certain months it is related to the tradition of visiting graves. The price of roses can be very high due to high demand. On the other hand, in normal months the market demand for roses is very low, while the rose harvest remains abundant, so the price of roses becomes very cheap, and sellers find it difficult to market them. To increase/maintain the economic value of roses, the Atma Jaya Yogyakarta University (UAJY) community service team provide training and provide equipment for processing rose flowers into rose water. Processing rose flowers into rose water uses a distillation process. The UAJY Faculty of Industrial Technology community service team designed the distillation equipment. The result of distilling rose water has many benefits and higher economic value, so it can increase the income of local people when the price of roses is cheap.

IntroductionKocuria rosea (K. rosea) is a gram-positive, aerobic, coagulase-negative coccoid that is generally considered as a non-pathogenic commensal. Infection from K. rosea is rare, and only limited number of case reports have been described. We aimed to investigate the clinical course and outcome of bacteremia caused by Kocuria rosea.Material and methodsWe reviewed and analyzed two cases of K. rosea bacteremia occurred at Istanbul Florence Nightingale Hospital and cases of this infection in published reports. The National Library of Medicine MEDLINE database was queried using the key terms “kocuria rosea, and kocuria rosea bacteremia" to identify published cases of K. rosea bacteremia.ResultsIn addition to our two cases, three cases of K. rosea bacteremia have been reported in the literature. The two infections occurred in our instutition were ICU-acquired. The first patient was that of a 89-year-old man, who was admitted to the ICU due to respiratory distress and pulmonary edema. The second patient was 64-year-old women with chronic renal failure, who was admitted to the ICU due to respiratory failure and hemodynamic instability. All five patients had succesful outcome.ConclusionsAlthough bacteremia due to K. rosea remains rare, and the organism is generally considered to be nonpathogen, it should be considered pathogen in both nosocomial and community acquired infections.

Résumé :
Clonostachys rosea is an excellent biocontrol fungus against numerous fungal plant pathogens. The cAMP signaling pathway is a crucial signal transduction pathway in fungi. To date, the role of the cAMP signaling pathway in C. rosea mycoparasitism remains unknown. An adenylate cyclase-encoding gene, crac (an important component of the cAMP signaling pathway), was previously screened from C. rosea 67-1, and its expression level was dramatically upregulated during the C. rosea mycoparasitization of the sclerotia of Sclerotinia sclerotiorum. In this study, the function of crac in C. rosea mycoparasitism was explored through gene knockout and complementation. The obtained results show that the deletion of crac influenced the growth rate and colony morphology of C. rosea, as well as the tolerance to NaCl and H2O2 stress. The mycoparasitic effects on the sclerotia of S. sclerotiorum and the biocontrol capacity on soybean Sclerotinia stem rot in ∆crac-6 and ∆crac-13 were both attenuated compared with that of the wild-type strain and complementation transformants. To understand the regulatory mechanism of crac during C. rosea mycoparasitism, transcriptomic analysis was conducted between the wild-type strain and knockout mutant. A number of biocontrol-related genes, including genes encoding cell wall-degrading enzymes and transporters, were significantly differentially expressed during C. rosea mycoparasitism, suggesting that crac may be involved in C. rosea mycoparasitism by regulating the expression of these DEGs. These findings provide insight for further exploring the molecular mechanism of C. rosea mycoparasitism.
