摘要
由土传病原体引起的植物病害是作物生产的主要限制因素。青萎病是由青枯菌群(Ralstonia solanacearum Species Complex)中的土壤细菌引起的,在世界各地造成了严重的作物损失。Ralstonia侵入根系并定植于植物木质部,改变植物生理,最终导致易感品种的植物枯萎。阐明雷氏菌如何入侵和定植植物是制定作物保护战略的核心。在这里,我们从根的检测和附着、早期根定殖、木质部入侵和随后的萎蔫等方面综述了Ralstonia的发病机制。我们主要关注过去5-10年的番茄研究。最近的工作已经确定了Ralstonia适应植物木质部的优雅机制,并发现了新的基因,这些基因在植物中起到了Ralstone适应性的作用。一种用途惊人的病原体正在出现,它使用多种策略使周围环境更加适宜,并能够适应新的环境。
Plant diseases caused by soilborne pathogens are a major limiting factor in crop production. Bacterial wilt disease, caused by soilborne bacteria in the Ralstonia solanacearum Species Complex (Ralstonia), results in significant crop loss throughout the world. Ralstonia invades root systems and colonizes plant xylem, changing plant physiology and ultimately causing plant wilting in susceptible varieties. Elucidating how Ralstonia invades and colonizes plants is central to developing strategies for crop protection. Here we review Ralstonia pathogenesis from root detection and attachment, early root colonization, xylem invasion and subsequent wilting. We focus primarily on studies in tomato from the last 5–10 years. Recent work has identified elegant mechanisms Ralstonia uses to adapt to the plant xylem, and has discovered new genes that function in Ralstonia fitness in planta. A picture is emerging of an amazingly versatile pathogen that uses multiple strategies to make its surrounding environment more hospitable and can adapt to new environments.
期刊介绍:
Seminars in Cell and Developmental Biology is a review journal dedicated to keeping scientists informed of developments in the field of molecular cell and developmental biology, on a topic by topic basis. Each issue is thematic in approach, devoted to an important topic of interest to cell and developmental biologists, focusing on the latest advances and their specific implications.
The aim of each issue is to provide a coordinated, readable, and lively review of a selected area, published rapidly to ensure currency.
