Progress in Studies on Rice Stigma Exposure
摘要
Abstract
In hybrid rice production,increasing the exposure of rice stigmas plays a crucial role in enhancing the outcrossing seed setting and boosting the yield of breeding and seed production in rice sterile lines.With the continuous progress in molecular biology and genetics,we have gained a deeper understanding of the mechanisms regulating the exposure of the rice stigmas.This study reviews the latest research progress on the exposure of the rice stigmas.The article discusses in detail how genetic and environmental factors af-fect the stigma exposure,and analyzes the molecular regulation mechanisms of this process,and summarizes the research progress in improving stigma traits of the rice using breeding strategies of the molecular marker-assisted selection.By comprehensively summarizing these research findings,this article aims to provide theoretical basis and practical references for improving stigma exposure and out-crossing habits of male sterile lines in hybrid rice.关键词
