摘 要:摘 要:高等植物细胞内囊泡运输介导了膜结构之间的物质运输和信号转导,其中,胞吐调控了运输囊泡向质膜的转运,参与了植物细胞壁形成、细胞分泌和环境响应等多种生物学过程。胞吐可以通过重构及强化细胞壁阻止病原体定殖、分泌抗微生物因子抵御病原体的入侵以及调控植物激素载体蛋白和受体蛋白的极性运输等参与抗病应答。遗传学证据表明胞吐是调控植物生物胁迫响应的重要机制。该文综述胞吐参与植物生物胁迫应答分子机制的研究进展,以期为本领域研究提供参考。
Abstract: Abstract: Membrane trafficking in eukaryotic cells mediates the transport of molecules between membrane structures. Exocytosis is the process of cargo delivery from trans-Golgi network (TGN) to plasma membrane, which is involved in a variety of biological processes, such as cell wall formation, cell secretion and environmental responses. Exocytosis mediates plant resistance response to pathogen attack through cell wall remodeling and enhancement, secretion of antimicrobial factors and recycling of plasma membrane localized receptors for antipathogen signaling. More and more genetic evidences indicated that exocytosis is an important mechanism regulating the response of plant immunity. Here, we summarizes research progress on the exocytosis in biotic stress responses, providing references for the further research in this field.
