TL;DR: In this study, 229 DNA sequences of cytochrome oxidase subunit I gene (COI) from 158 marine fishes of Japan were employed to test the efficacy of species identification by DNA barcoding and provided a new way for fish identification.

TL;DR: The results indicated that the SCoT analysis better represents the actual relationships than ISSR analysis, although both analyses give similar results.

TL;DR: A new secondary metabolite, 8-hydroxy-4 E ,6 E -octadien-3-one, was isolated from the seaweed Gracilaria lemaneiformis together with previously uncharacterized loliolide, which showed moderate allelopahic effect on the growth of the red tide alga Skeletonema costatum.

TL;DR: From the culture of an endophyte Chaetomium globosum found in Ginkgo biloba, twelve metabolites, including three diketopiperazines, two cytochalasins, two sterols, two simple phenolic compounds, one complex aromatic compound, a nonprotein amino acid and a linear triterpene were isolated.

TL;DR: Higher alkaloid levels were recorded for plants under salt or drought stress, with levels of ergonovine being higher than those of ergine, which increased over the plant growing period.

TL;DR: Genetic drift played a more important role than gene flow in the current population genetic structure of M .

TL;DR: The chemical composition and biological activity of wild Lavandula luisieri (Rozeira) Rivas-Martinez populations from the south Beira interior region in central eastern Portugal are described and one of these populations has been adapted to experimental field cultivation.

TL;DR: The essential oils and phenolic constituents from the aerial parts of Hypericum triquetrifolium Turra, were analyzed at three developmental stages (vegetative, flowering and fruiting stages) and rutin, hyperoside, quercitrin and quercetin were reported as the main components.

TL;DR: The essential oils of P. dilatatum presented in this paper, containing only mono- and sesquiterpenes as its major components, is further chemotaxonomic evidence of this dichotomy in the Piper genus.

TL;DR: A phylogeographical study of L. ilicifolius with 168 individuals from 14 populations was performed to assess geographical patterns and genetic variation in relation to past climate change, suggesting Climatic oscillation, aridification, and desert expansion within these regions have molded current distribution and biodiversity of the species.

TL;DR: Results indicated significant interaction between NH 3 –N and MC-LR on glutathione (GSH) and malondialdehyde (MDA) levels in newly-hatched larvae and 21-day-old larvae of silver carp Hypophthalmichthys molitrix.

TL;DR: The results strengthen the theory that these secretions of Acanthodactylus boskianus are used as semiochemicals, and lays the foundations to test in future the role of chemical cues in mate choice and dominance hierarchies in lizards.

TL;DR: The high genetic connectivity found among populations of A. nitidiflorus is an evidence of a recent habitat fragmentation and a bottleneck event in the past has been revealed, with a subsequent reduction of population size and a loss of genetic variation.

TL;DR: Wang et al. as discussed by the authors analyzed population genetic diversity of Scylla paramamosain in Hainan Island of China based on COI gene sequence, which revealed a potential population expansion event for this crab species.

TL;DR: Leaf essential oils of Pimenta pseudocaryophyllus from the central Brazilian Cerrado were obtained by hydrodistillation and investigated by GC and GC-MS as mentioned in this paper.

TL;DR: Punus dulcis L. ‘Mamaei’ is grown widely in souhtwest of Iran and blooms in early spring when temperatures are still low, but the possible factors for low germination percentage in this cultivar have not been reported.

TL;DR: It is demonstrated that the T. dealbata roots aqueous extract can significantly inhibit the growth of A. flos-aquae and M. aeruginosa and can induce a decrease in chlorophyll a content and an inhibition in total dehydrogenase activity of the phytoplankton assemblages.

TL;DR: A significant correlation between chemical and genetic data was observed and a high genetic differentiation among populations was observed, and the conservation strategies of populations should be made for each morph according to its level of diversity and bioclimate.

TL;DR: Allelopathic effect of saturated aqueous solution of the volatile oil from Descurainia sophia on seedling growth of test wheat cultivar and the effect on the microbial populations of the soil underneath wheat cultivars are studied.

TL;DR: The high variability indices calculated on M. cephalus individuals pooled together and the very low variability indices detected at some geographic sampling sites suggest that gray mullet populations have undergone a long-term reproductive isolation characterized by events of population abundance reductions which may have favored genetic differentiation among populations.

TL;DR: These newly developed EST-SSR markers will be useful for further studies such as taxonomy and molecular breeding studies and will further enhance the scientific understanding of the population genetic and conservation of Liriope and Ophiopogon.

TL;DR: Endophytic fungus Penicillium chrysogenum, a new source of hypocrellins Liyuan Meng, Peng Sun, Hua Tang, Ling Li, Siegfried Draeger, Barbara Schulz, Karsten Krohn, Hidayat Hussain, Wen Zhang and Yanghua Yi.

TL;DR: AFLP results indicated that O. basilicum had the greatest variation, while O. ciliatum showed the least variation, and minimum should be considered as a variety of O. Basilicum.

TL;DR: Using amplified fragment length polymorphism (AFLP), analyses revealed significant genetic differentiation among the six samples, indicating at least six separate populations of silver pomfret in the Southern Yellow and East China Seas.

TL;DR: Tests of neutral evolution and analysis of mismatch distribution suggested that miiuy croaker might have undergone a population expansion, and the knowledge on genetic diversity and genetic structure will be crucial to establish appropriate fishery management stocks for the species.

TL;DR: Comparison between molecular markers revealed that SRAP methods were considered more efficient than EST-SSR for screening Panicum accessions and Panicum amarum was found to be the closest species to switchgrass.

TL;DR: The results indicate that the ISSR method is sufficiently informative and powerful to estimate the genetic diversity in M. koenigii populations, and information on genetic variability might be a potential source as breeding material for development of commercially valuable traits in the plants.

TL;DR: Gene flow in Chinese populations of the dioecious Ficus tikoua, a prostrate shrub with figs partially buried in the soil, suggests that growth form may determine differences in gene flow between fig species.
