Abstract Background Plant growth-promoting bacteria (PGPB) can be used as a safe and sustainable agricultural measure to increase plant yield. In this study, cultivable rhizospheric, endophytic, epiphytic associated with canola were isolated on nutrient agar medium. The SDS-PAGE method was for grouping the bacterial strains. Bacterial strains more than 80% similarity in their protein patterns p...
Nutrients shape the growth, maturation, and aging of plants and animals. In plants, the juvenile to adult transition (vegetative phase change) is initiated by a decrease in miR156. In Arabidopsis, we found that exogenous sugar decreased the abundance of miR156, whereas reduced photosynthesis increased the level of this miRNA. This effect was correlated with a change in the timing of vegetative ...
Plant diversity has evolved and is evolving on the earth today according to the processes of natural selection. All basic "body plans" of vascular plants were in existence by the Early Carboniferous, approximately 340 million years ago, and each major radiation occupied a particular habitat type, for example, wetland versus terra firma, pristine versus disturbed environments. Today the great sp...
مقدمه: سندرم متابولیک یک فنوتیپ مرکب است که 32 درصد از افراد ایرانی به آن مبتلا می باشند. این بیماری با افزایش ریسک ابتلا به بیماری های قلبی- عروقی همراه می باشد. فراوانترین فنوتیپ این بیماری کاهش میزان hdl-c می باشد. برای شناسایی دلیل کاهشhdl-c نیاز به شناسایی ژنهای اثر گذار بر متابولیسم آن می باشد . مواد و روش ها: در مطالعه حاضر 107 خانواده با الگوی سندرم متابولیک و کاهش میزان hdl-c جهت بررس...
The Mi gene in tomato (Solanum lycopersicum) is a single, dominant resistance (R) gene that confers resistance against several species of insects and root-knot nematodes. This study examined the impact of root-knot nematode infestation and the plant growth and reproduction of near-isogenic tomato cultivars with and without Mi. The objectives of this experiment were to examine the potential fitn...
Conspicuous asymmetries in forms that are polymorphic within a species can be genetically or environmentally determined. Here, we present a genetic analysis of the inheritance of dimorphic enantiostyly, a sexual polymorphism in which all owers on a plant have styles that are consistently de ected either to the left or the right side of the oral axis. Using Heteranthera multi ora (Ponteder...
