表型组学在水稻研究中的应用

水稻作为重要粮食作物,其重要农艺性状的功能基因组研究是植物生物学研究的热点。植物基因型、表型和环境三者构成了遗传学研究的铁三角。随着高通量测序技术的快速发展,基因型的研究更加简单快速。然而表型研究严重滞后于基因型研究。目前传统的表型信息的获取存在所需劳动量巨大、成本高,所获取表型数据受人工主观因素影响大等诸多难题。高通量表型组学可无损、高通量、精准获取表型信息,对解决以上难题具有关键作用。本文对表型组学在水稻中的研究应用情况进行整理,为今后水稻基因组学和表型组学等多学科相结合的现代研究手段提供理论支撑。

Application of Phenomics in Rice Research

As the staple crop throughout the world, rice functional genomic research for the important agronomic traits is a hotspot in plant biology research area. The genotype, phenotype, and environmental factors are three critical components of the genetic research in plant. The development of high-throughput sequencing technology makes plant genotyping easier. However, phenomics research has trailed the genotype research. Being labor-intensive, high-cost, and susceptible to artificial subjectivity, the conventional phenotyping techniques could not obtain adequate genetic information. Phenomics technique, which is non-invasive and high-throughput to obtain accurate phenotypes, plays a key role in solving the above problems existing in traditional phenotyping techniques. In this review, the application of plant phenomics in rice research is summarized, which provides theoretical support for the modern rice research methods that combines genomics with phenomics.
