[Ab] Resumo:Wild plants of the family Convolvulaceae are hosts for a few New World begomoviruses (genus Begomovirus, family Geminiviridae). In this work, we report the complete genome sequence of a new begomovirus infecting the wild convolvulaceous plant Jacquemontia tamnifolia in Venezuela. The cloned bipartite genome showed the organization of typical New World begomoviruses and was found to be phylogenetically related to those of begomoviruses from Venezuela and other Caribbean countries. Several recombination events have been shown to have occurred involving genome fragment exchange with related begomoviruses infecting crops such as tomato and cucurbits and wild plants, including Jacquemontia sp. We propose the name jacquemontia yellow vein virus (JacYVV) for this new begomovirus.

[Ab] Resumo:ETHNOPHARMACOLOGICAL RELEVANCE: Ipomoea pes-caprae is known as bayhops, beach morning glory or goat's foot, and in Brazil as salsa-de-praia. Its leaves are used in worldwide folk medicine for the relief of jellyfish-stings symptoms. The literature only reports the neutralizing effects of nonpolar plant derived over jellyfish venoms, without validating the popular use or exploring the mechanism of action. AIM OF THE STUDY: This study aimed to evaluate and validate the topical effects of a semisolid containing hydroethanolic extract obtained from the aerial parts of I. pes-caprae using different models of paw- and ear-oedema and spontaneous nociception in mice, attempting to better understand the mechanism involved in its effect. MATERIALS AND METHODS: Leaf and stem of I. pes-caprae were extracted by ethanol 50% (v/v) and the soft-extract was incorporated in Hostacerin® cream base at 0.5%, 1.0% and 2% (w/w). The anti-hypersensitivity effects were evaluated by injecting the Physalia physalis venom into the right mice's hindpaw pre-treated either with the semisolid containing the I. pes-caprae extract or with the isolated majority compound 3,5-Di-O-caffeoylquinic acid (ISA). The topical anti-inflammatory activity was investigated using both preclinical models: paw oedema induced by trypsin, bradykinin (BK), histamine and carrageenan, and ear oedema induced by capsaicin. Additionally, the model of spontaneous nociception induced by trypsin and capsaicin were used to verify the topical antinociceptive activity. RESULTS: The animals pre-treated with the semisolid containing I. pes-caprae extract or with the intraplantar injection of the major component (ISA) had the mechanical hypersensitivity induced by P. physalis venom significantly reduced. Significant inhibition was also observed in paw-oedema induced by trypsin, histamine and BK, and in a less extent in carrageenan-induced paw oedema. Similar effect was observed in mice challenged to the capsaicin-induced ear-oedema. Besides the vascular effects, the extract interfered with leukocyte migration induced by histamine injection. Finally, the semisolid presented significant inhibition in trypsin- and capsaicin-induced spontaneous nociception. CONCLUSIONS: The hydroethanolic extract of I. pes-caprae showed compliance with the topical popular use of the herbal product to relieve the symptoms evoked by the cnidarian venom-skin contact, such as neurogenic oedema and nociception. The extract components seem to interfere with the effects resulting from the TRPV1, B R and PAR-2 activation, once it interfered with painful-behaviour and oedema induced by capsaicin, BK and trypsin, pointing the histaminergic system as the main target, once it is an important mediator in the signalling pathway of the aforementioned receptors.

[Ab] Resumo:BACKGROUND: The superior genus Jacquemontia belongs to Convolvulaceae, with around 120 species, and is also considered taxonomically difficult. The aim of this experiment was to assess the sedative and hypnotic activities of methanol extract from the leaves of Jacquemontia paniculata (Burm.f.) Hallier f. METHODS: The sedative and hypnotic activities were evaluated by hole-cross, open field, hole-board, elevated plus maze (EPM), and thiopental sodium-induced sleeping time determination tests in mice at doses of 200 and 400 mg/kg. RESULTS: In this investigation, we found that methanol extract of Jacquemontia paniculata (MEJP) produced a significant dose-dependent inhibition of spontaneous activity of mice both in hole-cross and open field tests. In addition, it also decreased the number of head dips in hole-board test. In the case of EPM test, this crude extract induced an anxiogenic-like effect rather than anxiolytic effect in mice. Moreover, MEJP significantly decreased the induction time to sleep and prolonged the duration of sleeping, induced by thiopental sodium. CONCLUSIONS: To conclude, these results suggest that the MEJP leaves possess potent sedative and hypnotic activities, which supported its therapeutic use for sleep disorders like insomnia.

[Ab] Resumo:Three new phenolic compounds, acutacoside C (1), acutacoside D (2) and acutacoside E (3) were isolated from the aerial part of Argyreia acuta. The oligosaccharide chain was composed of two glucoses and three rhamnoses, and the aglycone was (11S)-hydroxyhexadecanoic acid (jalapinolic acid). The core of the three compounds was operculinic acid B, which was rare in resin glycosides. Their structures were established by a combination of spectroscopic and chemical methods. Compounds 1-3 have been evaluated for inhibitory activity against α-glucosidase, which all showed weak inhibitory activities.

[Ab] Resumo:A facile and green strategy is reported here to synthesize gold (Au), silver (Ag) and gold-silver (Au-Ag) alloy nanoparticles (NPs) through bio-reduction reactions of aqueous corresponding metal precursors mediated by extracts of aerial parts of R. hypocrateriformis, which act as both reducing and stabilizing agents, under microwave irradiation. UV-vis spectrophotometer, XRD, FT-IR, FESEM/TEM, TGA and EDAX analysis were used to characterize the obtained NPs. The formation of NPs is evident from their surface plasmon resonance peak observed at λ =∼550, 450 and 500nm for Au, Ag and Au-Ag alloy NPs respectively. XRD pattern revealed that fcc structure, while FT-IR spectra signify the presence of phytochemicals adsorbed on NPs. Such a biofunctionalized NPs were characterized by their weight loss, 30% due to thermal degradation of plant phytochemicals observed in TG analysis. The spherical shape of Au, Ag and Au-Ag alloy NPs (∼10-50nm) is observed by FE-SEM/TEM images. EDAX analysis confirms the expected elemental composition. Moreover, these NPs showed enhanced antimicrobial, antioxidant, and anticancer activities, though it is more pronounced for Au-Ag alloy NPs, which is due to the combining effect of phytochemicals, Au and Ag metals. Thus, the biosynthesized NPs could be applied as effective growth inhibitors for various biomedical applications.

[Ab] Resumo:Parasitic plants thrive by infecting other plants. Flowering plants evolved parasitism independently at least 12 times, in all cases developing a unique multicellular organ called the haustorium that forms upon detection of haustorium-inducing factors derived from the host plant. This organ penetrates into the host stem or root and connects to its vasculature, allowing exchange of materials such as water, nutrients, proteins, nucleotides, pathogens, and retrotransposons between the host and the parasite. In this review, we focus on the formation and function of the haustorium in parasitic plants, with a specific emphasis on recent advances in molecular studies of root parasites in the Orobanchaceae and stem parasites in the Convolvulaceae.

[Ti] Título:How the temperate world was colonised by bindweeds: biogeography of the Convolvuleae (Convolvulaceae).
[So] Source:BMC Evol Biol;16:16, 2016 Jan 19.
[Is] ISSN:1471-2148
[Cp] País de publicação:England
[La] Idioma:eng
[Ab] Resumo:BACKGROUND: At a global scale, the temperate zone is highly fragmented both between and within hemispheres. This paper aims to investigate how the world's disjunct temperate zones have been colonised by the pan-temperate plant group Convolvuleae, sampling 148 of the c. 225 known species. We specifically determine the number and timing of amphitropical and transoceanic disjunctions, investigate the extent to which disjunctions in Convolvuleae are spatio-temporally congruent with those in other temperate plant groups and determine the impact of long-distance dispersal events on diversification rates. RESULTS: Eight major disjunctions are observed in Convolvuleae: two Northern Hemisphere, two Southern Hemisphere and four amphitropical. Diversity in the Southern Hemisphere is largely the result of a single colonisation of Africa 3.1-6.4 Ma, and subsequent dispersals from Africa to both Australasia and South America. Speciation rates within this monophyletic, largely Southern Hemisphere group (1.38 species Myr(-1)) are found to be over twice those of the tribe as a whole (0.64 species Myr(-1)). Increased speciation rates are also observed in Calystegia (1.65 species Myr(-1)). CONCLUSIONS: The Convolvuleae has colonised every continent of the world with a temperate biome in c. 18 Myr and eight major range disjunctions underlie this broad distribution. In keeping with other temperate lineages exhibiting disjunct distributions, long-distance dispersal is inferred as the main process explaining the patterns observed although for one American-Eurasian disjunction we cannot exclude vicariance. The colonisation of the temperate zones of the three southern continents within the last c. 4 Myr is likely to have stimulated high rates of diversification recovered in this group, with lineage accumulation rates comparable to those reported for adaptive radiations.

[Ti] Título:In vitro propagation and cell cultures of memory tonic herb Evolvulus alsinoides: a best source for elicited production of scopoletin.

[Ab] Resumo:Evolvulus alsinoides L. is used for preparation of 'Shankhapushpi', an important popular ayurvedic drug that contributes considerably to the improvement of memory power. The improvement is attributed to the presence of furanocoumarin scopoletin, a metabolite with a wide range of biological activities. This report describes, for the first time, an in vitro culture system for propagation and enhanced production of scopoletin. Different concentrations of auxins and cytokinins individually and in combination were used in Murashige and Skoog (MS) medium to induce shoot regeneration in cotyledonary nodal explants and callus formation in leaf explants. The best response was achieved in MS medium fortified with 5.0 µM 6-benzyladenine (BA) in which 96 % of cultures produced 7.6 ± 0.6 shoots per explant. Regenerated shoots were rooted on MS medium with 5.0 µM indole-3-acetic acid (IAA). Plantlets were successfully acclimatized and established in soil. MS medium fortified with 10 µM BA + 5.0 µM IAA showed maximum growth and accumulation of scopoletin in cell cultures. Cell cultures could be maintained over 24 months. The influences of auxins, cytokinins, organic acids, amino acids, and fungal-derived elicitors on production of scopoletin were studied. Presence of either L-arginine, sodium pyruvate, or yeast extract highly promoted scopoletin production as compared with control and achieved 75.02-, 72.13-, and 57.98-fold higher accumulation, respectively. The results presented herein have laid solid foundation for large-scale production of scopoletin and further investigation of its purification and utilization as a novel pharmaceutical drug.

[Ab] Resumo:Two new compounds of acutacosides 1 and 2, pentasaccharide resin glycosides were isolated from the aerial parts of Argyreia acuta. The core of the two compounds was operculinic acid A, and they were esterfied at the same position, just one substituent group was linked at C-2 of Rha. The absolute configuration of the aglycone in the two compounds was established by Mosher's method, which was (11S)-hydroxyhexadecanoic acid (jalapinolic acid). Their structures were established by a combination of spectroscopic and chemical methods.
