中文摘要：韧皮部取食性刺吸类昆虫是全球农业生产中危害最为严重的害虫类群之一，蚜虫等以韧皮部为主要取食部位的刺吸类昆虫通常在植物叶背、嫩茎以及花内等幼嫩组织取食为害，以特化的口针刺入植物韧皮部持续吸取汁液，导致植物营养成分流失，严重时可直接导致植株死亡。鉴于韧皮部是韧皮部取食性刺吸类昆虫最重要的取食部位，研究植物韧皮部防卫反应在抵御该类昆虫取食过程的作用机制则尤为重要。基于此，本文梳理了韧皮部防卫反应的作用方式（胼胝质沉积、韧皮部蛋白凝集）、调控机制（激素信号传导、转录调控、防卫相关基因表达等）、以及害虫唾液蛋白（激发子与效应子）在调控韧皮部防卫反应中的作用，系统性的从植物韧皮部防御激活、昆虫反防御两个方面，归纳了韧皮部防卫反应调控植物——韧皮部取食性刺吸类昆虫的互作过程，旨在为深入解析植物韧皮部抗虫机制，为基于韧皮部防卫反应的绿色防控技术研发提供理论参考，也为作物抗虫品种的分子设计与培育提供新思路
英文摘要：Phloem-feeding, piercing-sucking insects are one of the most destructive pests in global agricultural production. These insects, such as aphids, generally feed on tender plant tissues, including leaf undersides, young stems, and flowers. By penetrating the plant phloem and continuously ingesting phloem sap via specialized stylets, these pests consume plant nutrients and can even cause plant death. Given that plant phloem is the primary feeding site for phloem-feeding, piercing-sucking insects, it is important to investigate the mechanisms underlying the phloem-based defense (PBD) of plants against these pests. This review summarizes the functional modes of PBD (callose deposition and P protein plugging), their regulatory mechanisms (hormone signaling, transcriptional regulation, and the expression of defense-related genes), as well as the role of insect salivary proteins (elicitors and effectors) in modulating PBD. We elaborate on the interaction between plants and phloem-feeding, piercing-sucking insects from the perspective of PBD activation and insect counter-defense. This review aims to provide a theoretical basis for further understanding the defense mechanisms of plants against piercing-sucking insects, and for developing green pest management strategies based on PBD. It also offers new insights for the molecular design and breeding of insect-resistant crop varieties.
