Genome research promises to promote continued and enhanced plant genetic improvement. As a world's leading crop and a model system for studies of many biological processes, genomics research of cottons has advanced rapidly in the past few years. This article presents a comprehensive review on the recent advances of cotton genomics research. The reviewed areas include DNA markers, genetic maps, mapped genes and QTLs, ESTs, microarrays, gene expression profiling, BAC and BIBAC libraries, physical mapping, genome sequencing, and applications of genomic tools in cotton breeding. Analysis of the current status of each of the genome research areas suggests that the areas of physical mapping, QTL fine mapping, genome sequencing, nonfiber and nonovule EST development, gene expression profiling, and association studies between gene expression and fiber trait performance should be emphasized currently and in near future to accelerate utilization of the genomics research achievements for enhancing cotton genetic improvement.
基因组研究有望推动植物遗传改良的持续发展与提升。棉花作为全球主要作物以及众多生物学过程研究的模式系统，在过去几年中其基因组学研究进展迅速。本文对棉花基因组学研究的最新进展进行了全面综述。综述领域包括DNA标记、遗传图谱、定位基因与数量性状位点（QTL）、表达序列标签（EST）、微阵列、基因表达谱分析、细菌人工染色体（BAC）和双元细菌人工染色体（BIBAC）文库、物理图谱构建、基因组测序以及基因组工具在棉花育种中的应用。对每个基因组研究领域的现状分析表明，目前及不久的将来应着重关注物理图谱构建、QTL精细定位、基因组测序、非纤维和非胚珠EST开发、基因表达谱分析以及基因表达与纤维性状表现之间的关联研究，以加速利用基因组学研究成果来加强棉花遗传改良。
