Population Genomics of Yams: Evolution and Domestication of Dioscorea Species

چکیده
Abstract Yam is a collective name of tuber crops belonging to the genus Dioscorea . important not only as staple food crop but also an integral component society and culture millions people who depend on it. However, due its regional importance, yam has long been regarded “orphan crop” lacking global attention. Although this perception changing with recent advances in genomics technologies, domestication processes most species are still ambiguous. This mainly complicated evolutionary history caused by frequent hybridization polyploidization, which possibly dioecy that imposed obligate outcrossing In chapter, we provide overview evolution address from population perspectives focusing polyploidization. A review given studies hybrid origin D. rotundata West Central Africa, dispersion alata through human migrations, whole-genome duplication South America trifida end, give summary current understanding sex-determination system

15 صفحه اولEvolutionary Genomics of Peach and Almond Domestication
The domesticated almond [Prunus dulcis (L.) Batsch] and peach [P. persica (Mill.) D. A. Webb] originated on opposite sides of Asia and were independently domesticated ∼5000 yr ago. While interfertile, they possess alternate mating systems and differ in a number of morphological and physiological traits. Here, we evaluated patterns of genome-wide diversity in both almond and peach to better unde...
