Abstract

Abstract: 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 heterosis-associated 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.

Key words: proteomics, maize, heterosis, differentially expressed
