水稻细菌性条斑病和抗性育种研究进展

Research Progress on Rice Resistance to Bacterial Leaf Streak

水稻细菌性条斑病(简称细条病)是由Xanthom onas oryzae pv. oryzicola侵染引起的全球性病害,对水稻生产构成严重威胁。发掘和利用新抗源、定位克隆抗性基因及深入了解病原菌—水稻之间的相互作用机理等对于水稻抗细条病研究有重要意义。本文主要介绍了细条病的抗性鉴定与抗源筛选、抗性基因遗传分析与分子标记定位、抗性基因的克隆、抗性育种的研究现状,提出了加快抗细条病育种研究进程的建议。

Rice bacterial leaf streak（BLS） caused by Xanthomonas oryzae pv. oryzicola is one of the most widespread and destructive diseases, It is very important for us to explore and utilize novel resistance resources, map and clone resistant genes and elucidate the interaction mechanism between the pathogen and rice. In this review the re- cent research advances on resistant resources screening, inheritance analysis, mapping and cloning of resistant genes and breeding of rice with resistance to BLS were mainly summarized . Moreover,the suggestion for accelerating the breeding of rice with resistance to BLS was made.
