| 中文摘要:植物寄生线虫是一类专性活体营养寄生物，在植物根部维管束细胞附近诱导形成取食位点，与植物形成稳定的寄生关系，严重影响植物的生长发育，最终导致植物大幅度减产，甚至绝收。为长期、有效地防控植物寄生线虫，对线虫寄生、致病机制及其与植物的相互作用模式进行研究显得尤为重要。效应子在线虫整个寄生阶段中起着关键作用。近些年，线虫效应子的鉴定、功能、线虫效应子与植物相互作用模式等方面的研究取得了重要进展。本文主要针对病原物与寄主植物的相互作用模型、植物寄生线虫效应子鉴定、功能及线虫效应子与寄主植物的相互作用等方面的研究进展进行简单概述。 |

| Abstract:Plant parasitic nematodes are a group of obligate biotrophic pathogens, which establish the stable parasitic relationships with the host plants following induction and formation of the feeding sites close to the vascular bundle in the roots of host plants. This parasitism fairly influences the growth and development of plants, finally resulting in considerable losses of yield, even no harvests. For long-term and effective prevention and control of plant parasitic nematodes, it is necessary to study the mechanisms of parasitism and pathogenesis and interaction models. The nematode effectors play key roles in entire parasitism of nematodes. To date, many important progresses have been made in the areas relevant to the effectors of plant parasitic nematodes, including identification, functional analysis and interaction models. In this review, the progresses in interaction models between pathogens and host plants, identification and functions of plant parasitic nematode effectors and their interactions with host plants were briefly summarized. |
