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。
嫁接誘導植物變異是一種普遍存在的現象，已被廣汎應用于物質運輸、花期調節和信號的長距離傳導機製等方麵的研究。本文分析嫁接誘導變異的原因，併重點總結嫁接植物體內長距離傳遞的3類 RNA(外源類病毒或 RNA病毒、非編碼的小 RNA、植物內源 mRNA)；繫統綜述 RNA在嫁接植物體中傳遞機製方麵的國內外最新研究進展，對今後利用嫁接技術開展育種研究及存在的問題進行探討。

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.
