Gynmema sylvestre - A Potentional Medicinal Herb

Gymnema sylvestre (Gs) is a well proven anti diabetic plant and used in Indian system of medicine for long period. A new variant of Gs was identified having hairy leaf. This Gs hairy variant species was subjected for pharmacognostical studies and screened for phytochemical analysis and correlated with the previous work done normal non hairy species. The leaves were analyzed for macroscopic and microscopic characteristics by taking microtome sectioning and stained for viewing in slides. The dried powdered leaf was subjected to fluorescent study using chemical reagents and viewed under visible and UV light to study the coloring pattern of the powdered particles interacting with the reagents. The powder was subjected for physicochemical studies using Indian Ayurvedic Pharamacopoeia procedure. The different extractions were done by using 100%, 50% ethanol and water. These extracts were subjected for preliminary qualitative analysis, quantitative estimation of terpenoides, alkaloids and marker compound Glycemnic acid.

Integrative systematic revision of a new genus of Eumolpinae (Coleoptera: Chrysomelidae) endemic to New Caledonia: Dematotrichus gen. nov. and its numerous new hairy species

The monophyletic group of species around Dematochroma pilosa Jolivet, Verma & Mille is identified in this work by combining information from mitochondrial DNA data and morphological features. A series of defining traits diagnosing this species assemblage from its closest phylogenetic relatives, including the genera Thasycles Chapuis and Atrichatus Sharp, is used to argue for its taxonomic separation and propose a new genus, named Dematotrichus gen. nov. Both Dematochroma pilosa and Montrouzierella hispida Jolivet, Verma & Mille are transferred to the new genus as D. pilosus (Jolivet, Verma & Mille) comb. nov. and D. hispidus (Jolivet, Verma & Mille) comb. nov., and 11 new species are described: D. capillaris sp. nov., D. capillosus sp. nov., D. comans sp. nov., D. crinitus sp. nov., D. comatulus sp. nov., D. hirtus sp. nov., D. hirsutus sp. nov., D. horridus sp. nov., D. pubescens sp. nov., D. setosus sp. nov. and D. villosus sp. nov. The work includes an identification key for all the species in the new genus. http://zoobank.org/urn:lsid:zoobank.org:urn:lsid:zoobank.org:pub:0A3640A2-28B4-4592-9883-0DDB82BE4DB2

Can stress turn trees hair white? Hair covering of stems improves resilience of corticular photosynthesis against heat-stress

The hypothesis was tested that hair covering of stems improves resilience of corticular photosynthesis against heat stress. Hairy and non-hairy outer bark of Quercus ilex L. and Quercus robur L. trees was removed and optical properties measured. Additionally, structural bark traits and chlorophyll fluorescence parameters during heat stress treatment were studied. Optical analysis revealed a protective role of hairy outer bark (OB) against overheating of the underlying cortex of the stems. Hairiness decreased OB transmittance and increased thermal insulation of stems by an increased absorptance and reflectance of OB in the visible (380–720 nm) and an increased reflectance in the infrared part of the spectrum (720–900 nm). Simple linear regression analysis revealed no significant effect of stem structural traits (OB thickness (OBT), cortex density (Dcortex), cortex water content (Wcortex)) on corticular photochemistry (PScort), while optical traits of outer bark were significantly (P < 0.01) correlated with PScort. OB reflectance explained up to 91% of the variation in PSII quantum yield under heat stress. At high temperatures (> 45 °C) PScort of the hairy species showed a higher resilience and a better post-stress-recovery as compared to the non-hairy one. It is concluded that stem hairs play a physiologically significant role in modulating the stem energy balance due to a close interaction between optical characteristics of hairy OB and stem photochemical processes.

&lt;p&gt;&lt;strong&gt;Revision of &lt;em&gt;Begonia&lt;/em&gt; (Begoniaceae) in Bidoup-Nui Ba National Park, Southern Vietnam, including two new species&lt;/strong&gt;&lt;/p&gt;

The Begonia species occurring in Bidoup-Nui Ba National Park (Lam Dong Province, southern Vietnam) are reviewed based on recent floristic field surveys. Five species were recognized from the montane forests, and two of which are new to science. The new species belong to Begonia sect. Platycentrum and are named as B. hongiaoensis C.W.Lin, T.C.Hsu &amp; Luu and B. lamdongiana C.W.Lin, T.C.Hsu &amp; Luu, repectively. Begonia hongiaoensis most closely resembles B. siamensis Gagnep from northern Thailand. Both species have a rhizomatous habit and bear ovate leaves. However, the new species differs by its stoloniferous habit, shallowly cordate leaf base and 5-tepaled pistillate flowers. Begonia lamdongiana is similar to B. coelocentroides Y.M.Shui &amp; Z.D.Wei, a hairy leaf species of the same section in Yunnan of China, but is markedly distinct in its glabrous petioles, inflorescences, pedicels and ovaries, and larger bracts.

Stemona fimbritepala (Stemonaceae), a new species from northern Laos

Stemona fimbritepala (Stemonaceae), a new species from northern Laos, is described and illustrated. It is morphologically similar to S. hirtella and S. kerrii but clearly differs in longer peduncle, longer tepals, longer petaloid outgrowth of the connective and fimbriate margin of inner tepals. A detailed description, distribution, ecology, etymology, preliminary conservation status and photographs of this species are provided. A key to discriminate between the three hairy species is presented.

Psoroma spinuliferum(Pannariaceae),a new corticolous lichen species from Alaska with two different types of cephalodia

The species Psoroma spinuliferum is described here as new to science. It is only known from the holotype on a Picea sitchensis trunk near a sea-shore in southern, coastal Alaska. The species is distinct in having short, brittle, spinule-like hairs on both apothecium margins, thalline squamules and on pulvinate to coarsely coralloid cephalodia with emerald-colored Nostoc photobionts. These spinules are unique within Pannariaceae as they are developed on both the chlorobiont and on one of two cyanobionts, but it is uncertain whether they can act as vegetative propagules. The presence of two types of cephalodia is also unique within Pannariaceae. The second type consists of glabrous, small-foliose, geotropically arranged cephalodia, containing a Nostoc strain with cells of an intense ultramarine color, when observed after long storage. The species also has shorter ascospores than Psoroma paleaceum, another hairy species. The hair types of Psoroma hypnorum and P. paleaceum are here by contrast referred to as tomentum and scales, respectively.

Agro-economic performance of the association of beet with green cowpea in different amounts of hairy woodrose

ABSTRACT Intercropping systems of beet and green cowpea are beginning to be implemented in the northeastern semi-arid region in Brazil. The great challenge is to know if there is agro-economic efficiency in these systems when fertilized with organic matter produced by spontaneous species of the Caatinga biome. Thus, the objective of this research was to evaluate the effect of green manuring using different amounts of hairy woodrose (Merremia aegyptia) in the association of beet with green cowpea under the semi-arid conditions. The experiment was carried out at the Rafael Fernandes Experimental Farm, rural area of Mossoró, RN, Brazil, in the period of September-December 2015, in a randomized complete block design with four treatments and five replicates. The treatments consisted of hairy woodrose amounts incorporated into the soil (10, 25, 40, 55 t ha-1 on a dry basis). The cultivars of beet and green cowpea planted were ‘Early Wonder’ and ‘BRS Itaim’, recommended for the semi-arid conditions of the Brazilian Northeast. The best agro-economic performance for intercropping system of beet and green cowpea was obtained with 55 t ha-1 of hairy woodrose incorporated in the soil. The use of the hairy woodrose species as green manure is agronomically viable in intercropped systems with beet and green cowpea.

Genome-Wide Identification of the Mutation Underlying Fleece Variation and Discriminating Ancestral Hairy Species from Modern Woolly Sheep.

The composition and structure of fleece variation observed in mammals is a consequence of a strong selective pressure for fiber production after domestication. In sheep, fleece variation discriminates ancestral species carrying a long and hairy fleece from modern domestic sheep (Ovis aries) owning a short and woolly fleece. Here, we report that the “woolly” allele results from the insertion of an antisense EIF2S2 retrogene (called asEIF2S2) into the 3′ UTR of the IRF2BP2 gene leading to an abnormal IRF2BP2 transcript. We provide evidence that this chimeric IRF2BP2/asEIF2S2 messenger 1) targets the genuine sense EIF2S2 RNA and 2) creates a long endogenous double-stranded RNA which alters the expression of both EIF2S2 and IRF2BP2 mRNA. This represents a unique example of a phenotype arising via a RNA-RNA hybrid, itself generated through a retroposition mechanism. Our results bring new insights on the sheep population history thanks to the identification of the molecular origin of an evolutionary phenotypic variation.

Phaeophyscia esslingeri sp. nov. (Physciaceae, lichen-forming Ascomycota) – a new lichen species from Eastern Asia, with a world-wide key to the hairy species of the genus

Phaeophyscia esslingeri, a new species for science, is described from South Korea, Eastern Asia, compared with closely related taxa and illustrated with photographs. It is similar to Phaeophyscia hirtella, but diff ers by larger and light grey thallus, wider lobes, apothecia without a corona of dark rhizines around the base, shorter cortical hairs, and wider ascospores. Status of the hairy taxa of the genus Phaeophyscia from Eastern Asia is discussed. A world-wide key to hairy species of the genus Phaeophyscia is also included.

Sporormiella octomegaspora, a new hairy species with eight – celled ascospores from Spain

An ascolocular ascomycete with semi–immersed, hairy and pyriform pseudothecia, abundant pseudoparaphyses, fissitunicate 8-spored asci, and dark, very large 8-celled ascospores has been isolated from deer dung in Andalusia (Spain). Based on morphological features, a new species is erected and accommodated in Sporormiella, which the authors regard as a genus independent of Preussia. The new species is discussed and placed in a key, and a previous worldwide key to Sporormiella species with 8-celled spores is updated.

A new hairy species of Leptogium (Collemataceae) from China

This paper describes Leptogium weii sp. nov., a new hairy species from Sichuan, southwestern China. Leptogium weii has dense white tomentum on apothecial stalks and thalline margins. It closely resembles L. burnetiae in external morphology but differs in having globose isidia on the upper surface and dense tomentum on the apothecial stalk and thalline margin. A key is given to hairy species with tomentose apothecia.

Review of hairy species ofSelaginella (Selaginellaceae)of the West Indies, with description of two new species from Cuba

Abstract Caluff M. G. & Shelton G.: Review of hairy species of Selaginella (Selaginellaceae) of the West Indies, with description of two new species from Cuba [Novitiae florae cubensis 30]. — Willdenowia 39: 107–119. — Online ISSN 1868-6397; © 2009 BGBM Berlin-Dahlem. doi:10.3372/wi.39.39113 (available via http://dx.doi.org/) Five species of Selaginella growing in the West Indies present hairs on their leaves. They are here revised, with full descriptions, illustrations, specimen citations and an identification key. Two of them, both endemic to Cuba, are described as new to science: S. epipubens, an acidophilous species from W Cuba (Pinar del Rio province and Isla de la Juventud), and S. urquiolae, a calcicolous species from W Cuba (Pinar del Rio province).

Effects of variation in shade level, shade duration and light quality on perennial pastures

Two experiments examining the effect of artificial shade on pasture net herbage accumulation (NHA), botanical composition and soil characteristics were conducted between 1994 and 1999 at Whatawhata Research Centre. Both experiments included a range of shade levels (0–94%) and shade durations (3–12 months per year). Experiment 1 also included a light quality treatment, incorporating a range in the red:far red ratio (0.49–1.00). All three shading factors decreased annual NHA, with the most influential being the level of shade, which accounted for 68% of the variation and reduced NHA by 20–80% compared with open pasture. The second most influential factor was shade duration, which accounted for only 6% of the variation in NHA. Shading also led to changes in pasture botanical composition, most notably a decline in legume content in both experiments. There was no evidence that hairy pasture species (grasses or legumes) had any advantage over glabrous species under shade. At shade levels >60%, herbage nitrogen concentrations were elevated by 0.2 percentage points on a per unit dry weight basis, although reduced pasture NHA under higher shading meant lower demand for soil nitrogen. Potential nitrogen mineralisation measurements also indicated that nitrogen cycling is likely to be reduced under shading.

More, new Asian species in the lichen genus Fuscopannaria

In newly collected material from high altitudes in China and India three new species in the genus Fuscopannaria have been discovered: F. albomaculata, F. granulifera and F. hirsuta, all with unusual characters for the genus. The first one has remarkable tube-like structures exposing the white medulla above, the thallus thus appearing to be white-dotted. The second contains green algae, and the last one is the first regularly hairy species to be discovered in the genus.

TWO NEW HAIRY SPECIES OF CAPRELLA (AMPHIPODA) FROM THE STRAIT OF GIBRALTAR, WITH A REDESCRIPTION OF CAPRELLA GRANDIMANA

Abstract Two new hairy species of caprellid amphipod, Caprella monai and Caprella takeuchii, are described based on specimens from the Strait of Gibraltar. Caprella takeuchii was found on algae and intertidal sediment under rocks from Tarifa, Southern Spain, while Caprella monai was collected clinging to the hydroid Nemertesia antennina and living on sediments from Ceuta, northern Africa. The most outstanding characteristic for both species is the presence of dense setae along the body. Caprella takeuchii is very similar to Caprella acanthifera Leach, 1814, except for the presence of dense setae in the male and the differences in upper and lower lips. Caprella monai is closely related to the poorly known Caprella grandimana Mayer, 1882. In the present paper we also redescribe C. grandimana on the basis of specimens from the Strait of Gibraltar.
