WebbThe exerted stigma of rice seems to improve the outcrossing rate of the sterile lines [ 9, 10, 11 ]. The outcrossing in CMS lines is significantly increased by improving the floral traits, such as a longer duration of the floret opening, a longer stigma, a wider angle of the floret opening, and an exertion of higher stigma [ 8 ]. WebbDownloadable! Understanding and exploiting genetic diversity is a key factor for the productive and stable production of rice. Here, we utilize 73 high-quality genomes that encompass the subpopulation structure of Asian rice (Oryza sativa), plus the genomes of two wild relatives (O. rufipogon and O. punctata), to build a pan-genome inversion index …
