Intercellular communication in plants coordinates cellular functions during growth and development, and in response to environmental cues. RNAs figure prominently among the mobile signaling molecules used. Many hundreds of RNA species move over short and long distances, and can be mutually exchanged in biotic interactions. Understanding the specificity determinants of RNA mobility and the physiological relevance of this phenomenon are areas of active research. Here, we highlight the recent progress in our knowledge of small RNA and messenger RNA movement. Particular emphasis is given to novel insight into the specificity determinants of messenger RNA mobility, the role of small RNA movement in development, and the specificity of RNA exchange in plant-plant and plant-microbe interactions.
植物细胞间通讯在生长和发育过程中协调细胞功能，并对环境信号做出响应。RNA 是其中重要的一类可移动的信号分子。成百上千种 RNA 可以在短距离和长距离内移动，并在生物相互作用中相互交换。了解 RNA 迁移的特异性决定因素以及这种现象的生理相关性是当前研究的热点。本文重点介绍我们在小 RNA 和信使 RNA 迁移方面的最新认识。特别强调了信使 RNA 迁移特异性决定因素、小 RNA 迁移在发育中的作用以及植物-植物和植物-微生物相互作用中 RNA 交换的特异性等方面的新见解。
