BACKGROUND Habitat fragmentation, water resources and biological characteristics are important factors that shape the genetic structure and geographical distribution of desert plants. Analysis of the relationships between these factors and population genetic variation should help to determine the evolutionary potential and conservation strategies for genetic resources for desert plant populatio...

The genus Stachys belongs to Lamiaceae family with about 300 species and worldwide distribution. In the present study, the cytotoxic activity of four fractions of different Satchys species (S. byzatina C. Koch., S. inflata Benth., S. setifera Ten. and S. persica Gmel.), has been investigated against HT-29 (colon carcinoma), Caco-2 (colorectal adenocarcinoma), T-47D (breast ductal carcinoma) and...

arshadchamani rangelands are placed in the north foothill of sahandmountain and near kandovan village. therefore, it has plant diversity andeconomical values. in this region, medicinal plants are cut and sold by the storeswith non-standard packaging without scientific name. regarding the economicalvalue of medicinal plants and thereby the investment necessity on these valuableresources for usin...

The phenomenon of polyploidy and hybridization usually results in novel genetic combinations, leading to complex, reticulate evolution and incongruence among gene trees, which in turn may show different phylogenetic histories than the inherent species tree. The largest tribe within the subfamily Lamioideae (Lamiaceae), Stachydeae, which includes the globally distributed Stachys, and one of the ...

Hairy roots were induced by infecting stems and leaves of Glycyrrhiza inflata with Agrobacterium rhizogenes ATCC 15834. The optimization of growth and glycyrrhizin accumulation of G. inflata hairy roots was studied. Sucrose (6%, w/v) was optimal for growth and glycyrrhizin accumulation in G. inflata hairy roots. Effects of elicitors like chitosan, methyl jasmonate, and yeast extract on glycyrrh...
