玉米抗虫分子标记研究进展

Molecular Markers of Insect Resistance in Maize

玉米螟是危害玉米的主要害虫之一,总结玉米对咀嚼式口器害虫的抗虫机制。玉米的抗虫性与丁布含量、蛋白质种类及含量、蛋白酶抑制剂、植物组织或器官硬化程度等多种因素相关。综述玉米对4种主要害虫抗虫数量性状位点QTL的研究进展,将这些QTL与目前已知的抗虫相关基因和经过全基因组关联分析(GWAS)获得的候选基因进行对比,并对重叠基因进行分析介绍。

Maize boreris is one of the major pests in maize production. The maize insect resistant mechanism ofchewing pest was summarized. The insect resistance is related to DIMBOA content, defense proteins, protease inhib-itors, the hardness of plant tissue or organ, and so on. The known quantitative trait loci（QTL） to control different typemaize borers were further summarized and analyzed, especially the overlap region with insect-resistant QTLs andcandidate genes was paid more attention. The candidate genes with insect-resistance in maize were further de-scribed briefly.
