Abstract:

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.

Key words: long distance signal, long distance movement, vascular, systematic regulation
