Bromus auleticus is a winter wild species with promissory characteristics for domestication as forage that inhabits temperate-warm grasslands from wide region South America. Populations regions different environmental conditions are considered ecotypes and associated seedborne Epichloë fungal endophytes. Association provides B. increased growth capacity resistance against pathogens. The seeds m...

background herbal extracts have recently received the greatest attention in the path of finding naturally occurring chemicals with antibacterial and therapeutic value; however, each type of herbal remedy may have its own side effects. objectives the aim of the current experiment was to study the antibacterial effect of myrtle, parsley, mint, henna and chamomile extracts on escherichia coli and ...

a laboratory experiment was conducted to determine the allelopathic effect of residues aqueous extract of two ecotype of swallowwort (cynanchum acutum l.) on germination traits of wheat (triticum aestivum l.). a factorial experiment based on a completely randomized design with four replications was conducted at islamic azad university of karaj in 2012. factors were two swallowwort ecotype (ghaz...

Based on the Stable Ecotype Model, evolution leads to the divergence of ecologically distinct populations (e.g., with different niches and/or behaviors) of ecologically interchangeable membership. In this study, pyrosequencing was used to provide deep sequence coverage of Synechococcus psaA genes and transcripts over a large number of habitat types in the Mushroom Spring microbial mat. Putative...

Coexistence of two or more populations by frequency-dependent selection is common in nature, and it often arises even in well-mixed experiments with microbes. If ecology is to be incorporated into models of population genetics, then it is important to represent accurately the functional form of frequency-dependent interactions. However, measuring this functional form is problematic for traditio...

The immunomodulatory bioassay-guided fractionation of the methanolic extract of henna (Lawsonia inermis L.; syn. Lawsonia alba L.) leaves resulted in the isolation of seven compounds; three have been isolated for the first time from the genus, namely p-coumaric acid, 2-methoxy-3-methyl-1,4-naphthoquinone and apiin, along with the previously isolated compounds: lawsone, apigenin, luteolin, and c...

BACKGROUND Among the most important factors in wound healing pathways are transforming growth factor beta1 and vascular endothelial growth factor. Fibroblasts are the main cell in all phases wound closure. In this study, the extracts of plant materials such as Adiantum capillus-veneris, Commiphora molmol, Aloe vera, and henna and one mixture of them were used to treatment of normal mouse skin f...
