嫁接是一种长期存在的技术，用于提高作物产量，提供对生物胁迫(包括土传病原体)的耐受性，以及对非生物胁迫(如寒冷、盐碱、干旱和重金属)的耐受性。目前，除了在园艺生产中的应用外，嫁接作为一种重要的研究工具已经得到了极大的重视，主要是关于根冠通讯的信号机制。最近的研究大多侧重于检测分子和信号因子的长距离运输，特别是植物激素、RNA、多肽和蛋白质。通过这些研究，在整个植物水平上对调控发育和逆境反应的潜在机制已经有了重大突破。正因为如此，本文的目的是概述嫁接作为植物科学的重要工具。因此，在接下来的部分中，我们将总结在植物研究中嫁接使用的最新和最相关的内容。
Grafting has been a long-standing technique used to improve crop production and provide tolerance to biotic stresses, including soil-borne pathogens, as well as tolerance to abiotic stresses, such as cold, salinity, drought, and heavy metals. Currently, beyond its use in horticultural production, grafting has received great prominence as an important research tool, mainly regarding signaling mechanisms related to root-shoot communication. Most of the emphasis from recent studies has been on detection of the long-distance transport of molecules and signaling factors, especially phytohormones, RNAs, peptides, and proteins. Through these studies, there have been significant breakthroughs about the underlying mechanisms implicated in the regulation of developmental and stress responses at the whole plant level. Because of this, the aim of this paper is to provide an overview of grafting as an important tool for plant science. Thus, in the following sections, we will summarize what is most recent and relevant in the use of grafting in plant research.
