摘要Since the completion of the rice genome sequencing project in 2005,we have entered the era of rice geno-mics,which is still in its ascendancy.Rice genomics studies can be classified into three stages:structural genomics,functional genomics,and quantitative genomics.Structural genomics refers primarily to genome sequencing for the construction of a complete map of rice genome sequence.This is fundamental for rice genetics and molecular biology research.Functional genomics aims to decode the functions of rice genes.Quantitative genomics is large-scale sequence-and statistics-based research to define the quan-titative traits and genetic features of rice populations.Rice genomics has been a transformative influence on rice biological research and contributes significantly to rice breeding,making rice a good model plant for studying crop sciences.
