Evolutionary history of the grasses.
While some scientists have been working to sequence and describe the human genome, with increasingly dramatic results, another set of scientists has been quietly providing a map of evolutionary history, a time line that shows how life has evolved. Unlike the genome projects, which accumulate megabases of sequence from many genes in one organism, evolutionary projects accumulate megabases of seq...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
Evolutionary history and complementary selective relaxation of the duplicated PI genes in grasses.
Gene duplication plays an important role in the evolution of organisms by allowing functional innovation and the divergence of duplicate genes. Previous studies found two PI-like genes in grass species, suggesting functional divergence between the paralogous copies. Here, we reconstructed the evolutionary history of two PI genes from major lineages of grasses and other monocot species, and demo...
متن کاملReconstructing the evolutionary history of paralogous APETALA1/FRUITFULL-like genes in grasses (Poaceae).
Gene duplication is an important mechanism for the generation of evolutionary novelty. Paralogous genes that are not silenced may evolve new functions (neofunctionalization) that will alter the developmental outcome of preexisting genetic pathways, partition ancestral functions (subfunctionalization) into divergent developmental modules, or function redundantly. Functional divergence can occur ...
