Abstract:

Variation induced by plant grafting is universal phenomenon, which has been widely used in studies on material transport and flowering regulation and signal transmission mechanism of long distance. In this paper, the reasons of graft-induced genetic variation were analyzed, and three kinds of RNA molecules with long-distance transportability in the grafted plants were emphatically summarized, including exogenous viriods or virus RNA, small non-protein-coding RNA (snRNA) and plant endogenous mRNA. This article systematically reviewed the latest research progress in transfer mechanisms of RNA in grafted plants at home and abroad. This review discussed the future breeding researches by using grafting and the existing problems.

Key words: grafting, variation, RNA, long-distance transport, breeding
