Gall-inducing insects and nematodes engage in sophisticated interactions with their host plants. These parasites can induce major morphological and physiological changes in host roots, leaves, and other tissues. Sedentary endoparasitic nematodes, root-knot and cyst nematodes in particular, as well as gall-inducing and leaf-mining insects, manipulate plant development to form unique organs that provide them with food from feeding cells. Sometimes, infected tissues may undergo a developmental switch resulting in the formation of aberrant and spectacular structures (clubs or galls). We describe here the complex interactions between these plant-reprogramming sedentary endoparasites and their infected hosts, focusing on similarities between strategies of plant manipulation. We highlight progress in our understanding of the host plant response to infection and focus on the nematode and insect molecules secreted in planta. We suggest thatlooking at similarities may identify convergent and conserved strategies and shed light on the promise they hold for the development of new management strategies in agriculture and forestry.
诱导昆虫和线虫与宿主植物进行复杂的相互作用。这些寄生虫可以诱导宿主根、叶和其他组织发生重大的形态和生理变化。特别是固着内寄生线虫、根结线虫和胞囊线虫，以及诱导瘿和潜叶的昆虫，操纵植物发育形成独特的器官，为它们提供来自食细胞的食物。有时，感染组织可能发生发育开关，导致异常和壮观结构（棒状或瘿瘤）的形成。我们在这里描述了这些植物重编程固着内寄生虫与其感染宿主之间的复杂相互作用，重点是植物操纵策略之间的相似性。我们强调了对宿主植物对感染反应的理解的进展，并重点关注在植物体内分泌的线虫和昆虫分子。我们认为，观察相似性可能会确定趋同和保守的策略，并阐明它们在农业和林业中开发新管理策略的潜力。
