Substitution Mapping and Allelic Variations of the Domestication Genes from O. rufipogon and O. nivara.

ABSTRACT:

Background

Domestication from wild rice species to cultivated rice is a key milestone, which involved changes of many specific traits and the variations of the genetic systems. Among the AA-genome wild rice species, O. rufipogon and O. nivara, have many favorable genes and thought to be progenitors of O. sativa.

Results

In the present study, by using O. rufipogon and O. nivara as donors, the single segment substitution lines (SSSLs) have been developed in the background of the elite indica cultivar, HJX74. In the SSSLs population, 11 genes for 5 domestication traits, including tiller angle, spreading panicle, awn, seed shattering, and red pericarp, were identified and mapped on 5 chromosomes through substitution mapping. Herein, allelic variations of 7 genes were found throu
