作物数量性状基因图位克隆研究进展

对数量性状基因(QTL)的鉴定和克隆不仅有利于从分子水平上阐明作物重要农艺性状的形成机理,而且对于有效开展这些性状的分子育种,进一步提高作物增产潜力具有重要意义.近年来作物QTL图位克隆取得了重要突破,一批QTL被成功克隆,而模式植物基因组研究的快速发展则为作物QTL图位克隆技术带来了新的策略和方法.本文就相关研究的主要进展和发展趋势进行了综述.

Advances in Map-based Cloning for Crop Quantitative Trait Loci

The identification of QTL facilitates may reveal the molecular base of many important agronomic traits and conduct efficient molecular breeding for these traits in order to increase crop productivity. In recent years, the breakthrough was made in the map-based cloning for QTLs of crops and a batch of QTLs were successfully isolated. The rapid progresses in the genomics of model plants have provided the new strategies and methods for the map-based cloning for crop QTLs. This presentation reviews the status and trend in relative researches.
