摘要
杂种优势是生物界普遍存在的一种现象,在玉米中已经广泛应用,但其形成的分子机理仍不清楚。蛋白质组学技术是一种高通量筛选重要功能蛋白的研究手段,在玉米杂种优势的形成上进行蛋白质组学研究有利于深入解析杂种优势形成的分子机制。简单介绍了玉米杂种优势的表现,并对玉米种子胚、苗期根系、叶片和雌穗等性状上有关杂种优势形成的分子机理的蛋白质组学研究进行了综述。
Heterosis results in the phenotypic superiority of a hybrid over its parents with respect to traits such as growth rate, reproductive success and yield. Heterosis has immense agronomic value and for decades has been utilized in maize breeding to produce superior high-yielding hybrids. However, the molecular mechanisms underlying this event are still not completely understood. One of the approaches to study heterosis at the molecular level is to compare the gene expression of hybrids and their parental inbred lines in order to identify heterosisassociated genes and gain insight into the processes governing this phenomenon. In this review, we outlined the heterosis behaviors in maize and proteomics researches on maize heterosis.
