植物病原-媒介昆虫互作:研究进展与展望

Plant pathogen-insect vector interactions: research progress and prospects

大多数植物病毒及一些植物病原细菌由介体昆虫传播。植物病原与介体昆虫关系的研究有助于找到防控介体传播病原的关键环节,因此植物病原与介体昆虫的互作关系是植物病原传播机理研究中的核心问题。本文概述了国内外在植物病原与介体昆虫互作研究的最新进展,推介了本专辑论文的主要内容,并在此基础上,从生态和进化的角度提出了在植物病原-媒介昆虫互作研究中以下3个值得关注的研究方向:(1)植物病原与介体昆虫互作对生态系统的影响;(2)昆虫介体传播植物病毒的不同方式之间的关联性以及病毒、介体和植物之间的协同进化关系;(3)自然条件下植物病原-媒介昆虫互作的机理。植物病原与媒介昆虫互作的研究,既是生态和进化的理论问题,也和植物病原及其介体昆虫的绿色防控密切相关。

Most plant viruses and some plant pathogenic bacteria are transmitted by insect vectors.Understandings on plant pathogen-insect vector interactions can facilitate the recognition of key issues in effective management of plant pathogens and their vectors.Therefore,pathogen-vector interaction has become one of the core topics in the studies of pathogen transmission mechanisms.This article reviewed the recent research progress in plant pathogen-insect vector interactions,introduced the main contents of papers in this issue,and based on them proposed the following three directions for future research from ecological and evolutionary perspectives:(1)the roles of the interactions between plant pathogens and insect vectors in reshaping ecological systems;(2)the inter-relationships between different modes of plant virus transmission by insect vectors,and issues related to co-evolution among viruses,vectors and plants;and(3)the mechanisms of interactions between plant pathogens and insect vectors in nature.Studies on plant pathogen-insect vector interactions are not only fundamentals in ecology and evolutionary biology,but closely related to effective management of plant pathogens and their insect vectors as well.
