摘　　要：植物寄生线虫是农作物主要病原物之一,每年造成作物大幅度减产和严重的经济损失。植物寄生线虫基因组学研究在揭示植物线虫与寄主互作分子机制和作物抗线虫品种的培育中发挥着不可替代的作用。随着高通量测序技术的广泛应用,多种重要的植物寄生线虫的基因组被破解和报道。在此基础上,通过比较基因组学进一步揭示了植物寄生线虫的起源和进化,功能基因组学的研究也取得了一系列重要的进展。本文对目前已报道的植物寄生线虫基因组的研究进展进行总结,在各基因组的基本特征、染色体组变异、串联重复序列、基因表达调控与基因协同表达、水平基因转移、效应蛋白发现和功能研究及基因家族扩张等方面进行综述,以期为植物线虫致病分子机制研究及防控新策略制定提供参考。Plant-parasitic nematodes parasitize various plants,resulting in crop yield reduction and serious economic losses.Genomics study of plant parasitic nematode play an irreplaceable role in revealing the molecular mechanism of interaction between parasitic nematodes and plants,as well as breeding nematode-resistant varieties.With the continuous development of high-throughput sequencing technology,the genome of multiple important plant parasitic nematodes has been revealed and reported.The evolution and origin of plant-parasitic nematodes have been more clearly defined by the development of comparative genomics,and some progress has been made in functional genomics of plant parasitic nematodes.This paper gives a brief review on the major research advances of plant-parasitic nematode genomes,including general features,genome variation,sequences of tandem repeat genes,gene regulation and gene co-expression,horizontal gene transfer,effectors discovery and gene family expansions,aiming at providing a reference for the research on the pathogenic molecular mechanism of plant nematodes and the development of new control strategies.
