摘要
株高作为玉米的重要农艺性状,对产量、耐肥性、抗倒伏影响显著。随着分子生物学的发展,针对玉米株高性状开展了大量研究工作。总结玉米株高相关的QTL定位和基因克隆研究进展,并采用元分析技术对187个信息完整的玉米株高QTL定位结果进行整合分析,获得10个一致性QTL,并在一致性QTL置信区间内发掘可能参与玉米株高调控的候选基因。
Plant height is an important agronomic trait that significantly effects grain yield,fertilizer tolerance and lodging resistance in maize. With the development of molecular biology,numbers of studies on QTL mapping of plant height have been carried out in maize. In this research,QTL mapping and gene cloning of plant height were summarized in mazie. With the meta-analysis,187 QTL underlying plant height were integrated and analyzed,and 10 ＂consensus＂ QTL were obtained. In the ＂consistency＂ QTL confidence interval,candidate genes involving in the regulation of plant height were explored.
