| 摘要: |
| 优良砧木或接穗可以显著促进嫁接植物生长，提高其抗逆性及果实产量和品质，是一种绿色安全可持续的方法。文章综述了植物嫁接后砧木与接穗在养分和水分吸收、激素调节、应激响应、嫁接亲和性以及RNA长距离运输、DNA甲基化等方面的相互作用及基因表达的响应机制，可为后续深入研究砧穗互作机制提供借鉴。 |

| Abstract: |
| As a green,safe and sustainable method in agricultural and horticultural practices,superior rootstocks or scions can significantly improve stress resistance and yield,fruit quality of grafted plants.This article reviews rootstock scion interactions including nutrient and water absorption,hormone regulation,stress response graft compatibility and RNA long-distance transport,DNA methylation and response mechanism of gene expression in grafted plants,aiming to provide basis for future research on rootstock scion interaction of grafted plants. |
| Key words: grafting interaction between rootstock and scion DNA methylation interactive mechanism |
