摘要
高等植物在应对复杂环境变化时,需要整合和协调不同器官与组织感知的信息,并通过一套精细且复杂的机制经维管系统向受体组织或器官传递,进而系统性协调植物整体的生长发育和环境响应。在维管系统中移动的信号物质称为长距离信号。近年来研究发现,能够长距离移动的信号分子主要有小RNA、mRNA、小肽、激素、第二信使以及蛋白质等几类,这些信号分子能够将细胞外刺激从感知组织传递到靶器官,从而系统性地调控植物发育进程和环境响应。本文重点总结了植物体内长距离移动的RNA、小肽和蛋白质这3类长距离信号分子在调控植物器官发育、养分吸收以及环境响应等方面的研究进展,并对该领域在作物育种方面的应用潜力进行了探讨和展望,以期为作物遗传育种应用提供理论基础。
The vascular system is responsible for the communication of information between different organs and the environment as a whole,so that it can coordinate the development of plants and respond to the changes of the environment.The signal substances moving in the vascular system are called long-distance signals.In recent years,it has been found that some long-distance molecular signals,such as microRNA,mRNA,small peptides,hormones,second messengers and proteins,can transmit extracellular stimuli from sensing tissues to target organs,so as to systematically regulate plant development process and environmental response.In this review,we summarize the molecular mechanisms of long-distance moving RNA,small peptides and proteins in plants to regulate plant organ development,nutrient uptake and stress resistance.The application potential of this field in crop breeding was discussed and prospected,in order to provide a theoretical basis for the application of genetics and breeding in crops.
