摘要
嫁接诱导植物变异是一种普遍存在的现象,已被广泛应用于物质运输、花期调节和信号的长距离传导机制等方面的研究。本文分析嫁接诱导变异的原因,并重点总结嫁接植物体内长距离传递的3类RNA(外源类病毒或RNA病毒、非编码的小RNA、植物内源mRNA);系统综述RNA在嫁接植物体中传递机制方面的国内外最新研究进展,对今后利用嫁接技术开展育种研究及存在的问题进行探讨。
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.
