我们的研究发现,水稻条纹病毒(RSV)的运动蛋白NSvc4可以定位于肌动蛋白丝、内质网、间连丝和叶绿体,但其在叶绿体中的作用不明确。在这里,我们证实了NSvc4在叶绿体中的积累,并且NSvc4的n端1-73氨基酸足以定位到叶绿体。我们提供的证据表明,叶绿体定位的NSvc4可以损害叶绿体介导的免疫。在烟叶中表达NSvc4可导致防御相关基因NbPR1、NbPR2和NbWRKY12的表达降低,并抑制叶绿体源性ROS的产生。此外,携带NSvc4的马铃薯病毒X (PVX)的传染性克隆的产生有助于PVX在N. benthamiana植物中感染。此外,我们还发现了两个与叶绿体相关的宿主因子NbGAPDH-A和NbPsbQ1,它们都可以与NSvc4相互作用。敲低NbGAPDH-A或NbPsbQ1均可促进RSV感染。我们的研究结果揭示了NSvc4在叶绿体中的详细功能。
Our previous research found that NSvc4, the movement protein of rice stripe virus (RSV), could localize to the actin filaments, endoplasmic reticulum, plasmodesmata, and chloroplast, but the roles of NSvc4 played in the chloroplast were opaque. Here, we confirm the accumulation of NSvc4 in the chloroplasts and the N-terminal 1–73 amino acids of NSvc4 are sufficient to localize to chloroplasts. We provide evidence to show that chloroplast-localized NSvc4 can impair the chloroplast-mediated immunity. Expressing NSvc4 in Nicotiana benthamiana leaves results in the decreased expression of defense-related genes NbPR1, NbPR2, and NbWRKY12 and the inhibition of chloroplast-derived ROS production. In addition, generation of an infectious clone of potato virus X (PVX) carrying NSvc4 facilitates PVX infection in N. benthamiana plants. Moreover, we identify two chloroplast-related host factors, named NbGAPDH-A and NbPsbQ1, both of which can interact with NSvc4. Knockdown of NbGAPDH-A or NbPsbQ1 can both promote RSV infection. Our results decipher a detailed function of NSvc4 in the chloroplast.
