Asian cultivated rice is grown worldwide and comprises the staple food for half of the global population.
Asian cultivated rice (O. sativa L). is generally considered to have been domesticated from Oryza rufipogon several thousands of years ago (Cheng et al. 2003; Huang et al. 2012; Khush 1997; Oka 1988).
Asian cultivated rice (Oryza sativa L). originated from common wild rice (Oryza rufipogon Griff)., and their morphological, biochemical and genetic relationships have been analyzed in many studies (Sun et al., 2001; Cai & Morishima 2002).
Asian cultivated rice, Oryza sativa, is thought to have originated from the Asian wild rice Oryza rufipogon only about 10,000 years ago, although the place and time of its domestication are still debated [8, 18, 22, 28].
Asian cultivated rice (O. sativa) originated from the wild ancestors (O.
Asian cultivated rice (Oryza sativa type indica and Oryza sativa. type japonica) has phenotypically divergent ecotypes [ 1].
Asian cultivated rice, Oryza sativa L., is divided into several genetically distinct groups, including indica, aus, aromatic, temperate, and tropical japonica (Garris et al. 2005).
Assessments of these calculations in whole collection and different subgroups (Asian cultivated and wild, African cultivated and wild) were performed using VCFtools with a sliding window 1000 bp in length and a 500-bp step size.
Our comparative analyses between cultivated and wild rice species revealed that Asian cultivated rice species have accumulated genomic deletions since their divergence from their wild ancestors.
There are two cultivated species in Oryza, O. glaberrima (African cultivated rice) and O. sativa (Asian cultivated rice).
