It becomes one of important research directions on crop genetics and breeding to investigate crop heterosis through gene expression when biology enters a era of functional genomics. The cDNAchip as a new molecular technique has provided a powerful tool to study heterosis under the gene expression level. The purpose of this study is to get the gene expression profile of the hybrid and its parents using cDNA chips in order to explore the molecular basis of heterosis.
In this study, an e...
