The origin, evolution, and distribution of cultivated barley provides powerful insights into the historic origin and early spread of agrarian culture. Here, population-based genetic diversity and phylogenetic analyses were performed to determine the evolution and origin of barley and how domestication and subsequent introgression have affected the genetic diversity and changes in cultivated bar...

BACKGROUND Knowledge about how frugivory and seed deposition are spatially distributed is valuable to understand the role of dispersers on the structure and dynamics of plant populations. This may be particularly important within anthropogenic areas, where either the patchy distribution of wild plants or the presence of cultivated fleshy-fruits may influence plant-disperser interactions. METH...

The bacterial endophytic communities residing within roots of maize (Zea mays L.) plants cultivated by a sustainable management in soils from the Quechua maize belt (Peruvian Andes) were examined using tags pyrosequencing spanning the V4 and V5 hypervariable regions of the 16S rRNA. Across four replicate libraries, two corresponding to sequences of endophytic bacteria from long time maize-culti...

identification and transfer of desirable genes from wild relatives to crop species is one of the breeding solutions for producing resistance to pathogens and pests. this study was conducted to evaluate crossability and the response to pythium ultimum in three species of the genus carthamus. to assess response to the pathogen, eight safflower (carthamus tinctorius l) genotypes, two ecotypes of c...

The appropriate temperature and growth supplementary factors such as fetal bovine serum (FBS) are the necessities needed for cell growth in culture medium. In this regards, the effect of Leibovitz-15 (L-15) medium containing different concentrations of fetal bovine serum (FBS) was assessed on growth and proliferation of cultivated liver cells of klunzingerchr('39')s mullet, Liza klunzingeri, in...

Background: Lemon verbena (Lippia citriodora H.B.K.) is an aromatic and medicinal plant of family Verbenaceae, which cultivated in North region of Iran. Objective: Evaluation of phytochemical characters in Lippia citriodora H.B.K. plantlets affected by propagation methods (micro-propagation and stem cutting) cultivated in different soil type (peat moss and mixture soil). Methods: This study w...

although wild safflower (c.oxyacantha, 2n=24) has not been studied to a very large extent, yet it is believed that it can be used as an important source of biotic and abiotic stress resistance genes for improvement of cultivated safflower (c.tinctorius l., 2n=2x=24). in this study, the crossability between these two (cultivated and wild safflower) species was evaluated as based upon morphology ...

The object of this study is to evaluate the influence of silymarins from cultivated and wild Silybum marianum L. plants with different content of flavonolignans, especially silibinin on serum lipids levels and on the experimental atherosclerosis development in rabbits fed on high cholesterol-diet (HCD). Forty eight male six-months-old white New Zealand rabbits (1.8-2 kg) were randomly assigne...

Variability in the cultivated germplasm for economic traits such as resistance to rice tungro virus, sheathblight, yellow stem borer, drought and salt tolerance is limited. This necessitated search for the genes in secondary and tertiary gene pool of genus Oryza. Fortunately, wild species are an important reservoir ofuseful genes for resistance to major disease, pest and tolerance t...
