摘要：

以高密度遗传图IBM2Neighbors整合公开发表的、控制68个性状的1201个玉米QTL,构建了用于分子标记发掘、QTL定位、基因克隆及分子标记辅助选择的综合图谱,并将结果融入本地化数据库CMap软件.利用CMap比较玉米QTL综合图和水稻QTL图谱发现,玉米和水稻QTL成簇分布具有普遍性;22个玉米株高QTL与64个水稻株高QTL位于标记水平上的共线性区域,43个玉米产量QTL与7个水稻QTL位于标记水平上的共线性区域.以控制玉米株高的QTL为例,利用overview的分析方法对127个QTL进行优化,定位了40个“真实”QTL,提高了QTL定位的准确性和有效性,发现了玉米和水稻株高相关QTG(quantitativetraitgene)的候选基因.本研究为大量玉米QTL信息的有效利用搭建了重要的生物信息学平台.
