中文摘要:昆虫介体(如粉虱)与其所传播病毒(如菜豆金黄花叶病毒属病毒)之间经由寄主植物的间接交互作用可能会产生一系列结果(取决于所涉及到的三个生物的物种/种类),而这种变化下潜在的机制尚不清楚。本研究观察了烟粉虱在三种番茄(茉莉酸相关的抗性水平有差异,并且未感染或已感染菜豆金黄花叶病毒)上的行为表现,探究JA相关的抗性在调节烟粉虱-菜豆金黄花叶病毒之间互作中的作用。研究结果表明,JA相关的抗性在烟粉虱、菜豆金黄花叶病毒与番茄植株的三重互作中起着重要的作用。
外文摘要:The indirect interactions between insect vectors, such as whiteflies, and the viruses they transmit, such as begomoviruses, via host plants may produce a range of outcome depending on the species/strain of each of the three organisms involved, and the mechanisms underlying the variations are not well understood. Here, we observed the performance of whiteflies on three types of tomato, which vary in level of jasmonic acid (JA)-related resistance and were either uninfected or infected by a begomovirus, to investigate the role of JA-related resistance in mediating whitefly-begomovirus interactions. Compared to the performance of whiteflies on plants of the wild type, the performance was elevated on plants deficient in JA-related resistance but reduced on plants with a high level of JA-related resistance. Further, on plants with a high level of JA-related resistance, the whitefly performed better on virus-infected than on uninfected plants; however, on tomato plants deficient in JA-related resistance, whitefly performance was less affected by the virus-infection of plants. Additionally, the expression of the JA-regulated defense gene PI-II in tomato plants was repressed by virus infection. These findings suggest that JA-related resistance plays an important role in the tripartite interactions between whitefly, begomovirus and tomato plant.
