[Ti] Título:The relationship between cell division and elongation during development of the nectar-yielding petal spur in Centranthus ruber (Valerianaceae).

[Ab] Resumo:BACKGROUND AND AIMS: Floral spurs are hollow, tubular outgrowths that typically conceal nectar. By their involvement in specialized pollinator interactions, spurs have ecological and evolutionary significance, often leading to speciation. Despite their importance and diversity in shape and size among angiosperm taxa, detailed investigations of the mechanism of spur development have been conducted only recently. METHODS: Initiation and growth of the nectar-yielding petal spur of Centranthus ruber 'Snowcloud' was investigated throughout seven stages, based on bud size and developmental events. The determination of the frequency of cell division, quantified for the first time in spurs, was conducted by confocal microscopy following 4',6-diamidino-2-phenylindole (DAPI) staining of mitotic figures. Moreover, using scanning electron microscospy of the outer petal spur surface unobstructed by trichomes, morphometry of epidermal cells was determined throughout development in order to understand the ontogeny of this elongate, hollow tube. KEY RESULTS: Spur growth from the corolla base initially included diffuse cell divisions identified among epidermal cells as the spur progressed through its early stages. However, cell divisions clearly diminished before a petal spur attained 30 % of its final length of 4·5 mm. Thereafter until anthesis, elongation of individual cells was primarily responsible for the spur's own extension. Consequently, a prolonged period of anisotropy, wherein epidermal cells elongated almost uniformly in all regions along the petal spur's longitudinal axis, contributed principally to the spur's mature length. CONCLUSIONS: This research demonstrates that anisotropic growth of epidermal cells - in the same orientation as spur elongation - chiefly explains petal spur extension in C. ruber. Representing the inaugural investigation of the cellular basis for spur ontogeny within the Euasterids II clade, this study complements the patterns in Aquilegia species (order Ranunculales, Eudicots) and Linaria vulgaris (order Lamiales, Euasterids I), thereby suggesting the existence of a common underlying mechanism for petal spur ontogeny in disparate dicot lineages.

[Ti] Título:Rapid isolation and cross-amplification of microsatellite markers in Plectritis congesta (Valerianaceae) with 454 sequencing.

[Ab] Resumo:PREMISE OF THE STUDY: Microsatellite markers were isolated and characterized in Plectritis congesta for studying the evolution of this highly variable species. METHODS AND RESULTS: We used 454 sequencing of DNA enriched for microsatellite repeats to develop microsatellite markers. This produced 262079 reads with an average length of 324 bp, representing approximately 800 microsatellite regions from which 48 primers were tested. Eleven markers reliably amplified without optimization. These primer pairs showed a high degree of heterozygosity and allelic diversity. Unexpectedly, half of the markers contained multiple peaks, with up to four alleles per individual, which suggests that either polyploidy or isolated gene duplication has occurred within this clade. These primers successfully cross-amplified in P. macrocera, indicating the utility of these markers for the genus. CONCLUSIONS: With variation in mating system and habitat, a mix of duplicated and nonduplicated markers, and high genetic variance, Plectritis is an ideal candidate model genus for studying the ecological and evolutionary consequences of gene duplication.

[Ab] Resumo:To explore the diversity in the essential oil yield and composition of Valeriana jatamansi Jones (syn. V. wallichii DC) growing wild in Uttarakhand (Western Himalaya), 17 populations were collected from different locations and grown under similar conditions. Comparative results showed considerable variations in the essential oil yield and composition. The essential oil yield varied from 0.21 to 0.46% in the fresh roots and rhizomes of different populations of V. jatamansi. Analysis of the essential oils by GC (RI) and GC/MS and the subsequent classification by principal component analysis (PCA) resulted in six clusters with significant variations in their terpenoid composition. Major components in the essential oils of the different populations were patchouli alcohol (1; 13.4-66.7%), α-bulnesene (3; <0.05-23.5%), α-guaiene (4; 0.2-13.3%), guaiol (5; <0.05-12.2%), seychellene (6; 0.2-9.9%) viridiflorol (<0.05-7.3%), and ß-gurjunene (7; 0.0-7.1%). V. jatamansi populations with contents of 1 higher than 60% may be utilized commercially in perfumery.

[Ab] Resumo:Quorum sensing is an important gene regulatory mechanism in Pseudomonas aeruginosa and controls the expression of numerous virulence factors. We designed and constructed a screening system for quorum-sensing inhibitors. We developed the system by using the lasI and rhlA promoters fused with promoterless sacB as reporters. Using this system we screened a number of Chinese herb extracts, and identified three herb extracts containing inhibitors to the quorum-sensing system and to its regulated genes. The screening system developed was highly efficient and sensitive. It could serve as a useful tool to identify herb compounds that block infections but unlikely render antibiotic resistance in pathogens.

[Ti] Título:Correlates of diversification in the plant clade Dipsacales: geographic movement and evolutionary innovations.
[So] Source:Am Nat;170 Suppl 2:S28-55, 2007 Aug.
[Is] ISSN:1537-5323

[La] Idioma:eng
[Ab] Resumo:We explore patterns of diversification in the plant clades Adoxaceae and Valerianaceae (within Dipsacales), evaluating correlations between biogeographic change (i.e., movements into new areas), morphological change (e.g., the origin of putative key innovations associated with vegetative and reproductive characters), and shifts in rates of diversification. Our findings indicate that rates of diversification in these plants tend to be less tightly correlated with the evolution of morphological innovations but instead exhibit a pronounced correlation with movement into new geographic areas, particularly the dispersal of lineages into new mountainous regions. The interdependence among apparent novelties (arising from their nested phylogenetic distribution) and the correlation between morphological and biogeographic change suggests a complex history of diversification in Dipsacales. Overall, these findings highlight the importance of incorporating biogeographic history in studies of diversification rates and in the study of geographic gradients in species richness. Furthermore, these results argue against a simple deterministic relationship between dispersal and diversification: like other factors that may influence the probability of speciation and/or extinction, the impact of dispersal on diversification rates depends on being in the right place at the right time.

[Ab] Resumo:Sedative effect of the aqueous extract of Centranthus longiflorus ssp. longiflorus (Cle-1) on intact and adrenalectomized rats was investigated using a thiopental sleeping test to clarify the relationship of this effect on adrenal gland hormones, particularly glucocorticoids. Adrenal gland hormones were found to play an important role in inhibiting the sedative effect of the investigated drugs. It is clear, however, that these hormones are not glucocorticoids. Glucocorticoids were not responsible for shortening the sleep period.

[Ab] Resumo:The aim of the study was to demonstrate competition between caffeine and a fixed valerian/hop extract combination (Ze91019) by the central adenosine mechanism. EEG was used to describe the action of caffeine on the central nervous system after oral administration (200 mg) in healthy volunteers. In addition to caffeine, the volunteers (16 in each group) received either placebo or verum (2 and 6 tablets containing the valerian/hop extract). The EEG responses were recorded every 30 min thereafter. The verum medication was capable of reducing (2 tablets) or inhibiting (6 tablets) the arousal induced by caffeine. This pharmacodynamic action was observed 60 minutes after oral administration, indicating not only competition between the antagonist caffeine and the partial agonist, i. e., the valerian/hop extract but also bio-availability of the compound(s) responsible for the agonistic action. In conclusion, the valerian/hop extract acts via a central adenosine mechanism which is possibly the reason for its sleep-inducing and -maintaining activity.

[Ab] Resumo:Antitubercular bioassay-guided fractionation of the n-hexane- and CH (2)Cl (2)-soluble extracts of the above-ground biomass and roots of Valeriana laxiflora led to the isolation of a new iridolactone, (4R,5R,7S,8S,9S)-7-hydroxy-8-hydroxymethyl-4-methyl-perhydrocyclopenta[ c]pyran-1-one ( 1), and a new lignan, (+)-1-hydroxy-2,6-bis- epi-pinoresinol ( 2), along with eleven known compounds, betulin ( 3), betulinic acid ( 4), 5,7-dihydroxy-3,6,4'-trimethoxyflavone ( 5), 23-hydroxyursolic acid ( 6), oleanolic acid ( 7), tricin ( 8), ursolic acid ( 9), ferulic acid, (+)-1-hydroxypinoresinol, prinsepiol, and 5,7,3'-trihydroxy-4'-methoxyflavone. The structures of compounds 1 and 2 were elucidated on the basis of spectroscopic evidence. The absolute stereochemistry of 1 was determined by chemical transformations and Mosher ester procedures. In a microplate alamar blue assay against Mycobacterium tuberculosis, compounds 2 - 9 exhibited minimum inhibitory concentrations (MIC) of 15.5 - 127 microg/mL, while the other isolates were regarded as inactive (MIC > 128 microg/mL). In addition, all the isolates were tested for cytotoxicity against African green monkey Vero cells in order to evaluate their selectivity potential.

[Ti] Título:Preliminary phylogeny of Valerianaceae (Dipsacales) inferred from nuclear and chloroplast DNA sequence data.

[Ab] Resumo:Valerianaceae is a relatively small (ca. 350 species), but morphologically diverse angiosperm clade. Sequence data from the entire ndhF gene, the trnL-F intergenic spacer region, the trnL intron, the matK region, the rbcL-atpB intergenic spacer region and internal transcribed spacer (ITS) region of nuclear ribosomal DNA were collected for 21 taxa within Dipsacaceae and Valerianaceae (1 and 20, respectively). These data were included in several phylogenetic analyses with previously published sequences from Dipsacales. Results from these analyses (maximum parsimony, maximum likelihood, and Bayesian analysis) are in strong agreement with many of the conclusions from previous studies, most importantly: (1) Valerianaceae is sister to Dipsacaceae; (2) Triplostegia is more closely related to species of Dipsacaceae than to Valerianaceae; and (3) Valeriana appears not to be monophyletic, with Valeriana celtica falling outside the remainder of the species of Valeriana sampled here (with very strong support). With the exception of V. celtica, these data support two major clades within Valeriana; one that is exclusively New World and another that is distributed in both the Old and New World. Although the species of Valerianaceae and its sister group Dipsacaceae plus Triplostegia, are widely distributed in the Northern Hemisphere, and the data imply that Valerianaceae diversified initially in Asia (the Himalayan Patrinia and Nardostachys falling at the base of the clade), the center of modern species diversity for the group is in the Andes of South America with as many as 175 species restricted to that region. Although the exclusively South American taxa form a clade in the chloroplast and combined ITS and chloroplast analyses, support values tend to be low. Future studies will need to include additional data, in the form of both characters and taxa, before any strong conclusions about the character evolution, diversification, and biogeography of the South American valerians can be made.
