Petals, defined as the showy laminar floral organs in the second floral whorl, have been shown to be under similar genetic control in distantly related core eudicot model organisms. On the basis of these findings, it is commonly assumed that the petal identity program regulated by B-class MADS-box gene homologs is invariant across the core eudicot clade. However, the core eudicots, which compri...
after the soviet union dissolution, a chaotic period was begun in the russia. russia lost its glory and felt disgrace. the first group of elites came to power under yeltsin; they tried to re-define russia’s identity as a european country and build a foreign policy on this baseline. therefore russia tried to become closer with the west especially with the u.s. according to their view the sovie...
به کارگیری روشهای بهینه سازی در تحلیل سیستم های عمران، همانند شبکه های توزیع آب و جمع آوری فاضلاب، منابع آب، سازه و... در چند دهه اخیر مورد توجه متخصصین این رشته واقع شده است. با توجه به هزینه بری فراوان طرحهای آب و فاضلاب (شبکه های توزیع آب و جمع آوری فاضلاب) لزوم به کارگیری روشهای نو و به صرفه برای طراحی و اجرای سیستم های مذکور احساس می شود. روشهای سنتی و مرسوم طراحی شبکه های توزیع آب و جمع آ...
Habitat degradation and loss can result in population decline and genetic erosion, limiting the ability of organisms to cope with environmental change, whether this is through evolutionary genetic response (requiring genetic variation) or through phenotypic plasticity (i.e., the ability of a given genotype to express a variable phenotype across environments). Here we address the question whethe...
The study of continuously varying, quantitative traits is important in evolutionary biology, agriculture, and medicine. Variation in such traits is attributable to many, possibly interacting, genes whose expression may be sensitive to the environment, which makes their dissection into underlying causative factors difficult. An important population parameter for quantitative traits is heritabili...
