几千年来，人们通过一种被称为嫁接的过程将不同的植物切割并连接在一起。当两个基因不同的生物体合二为一时，通过一个非凡的再生过程，被切断的组织粘附在一起，细胞分裂，脉管系统分化。嫁接在园艺中变得越来越重要，它为无性繁殖提供了一种有效的手段。嫁接还结合了理想的根和芽，以产生更有活力、更抗病原体和更抗非生物胁迫的嵌合体。因此，它提供了一种优雅而有效的方法，可以使用传统技术提高蔬菜和树木的植物生产力。尽管这在园艺上很重要，但我们才刚刚开始了解植物如何在嫁接点再生组织。通过更好地理解嫁接，我们可以阐明基本的再生途径和自我/非自我识别的基础。我们也可以更好地理解为什么许多植物有效地嫁接，而其他植物不能，目的是改进嫁接，以扩大嫁接植物的范围，创造更理想的嵌合体。在这里，我回顾了最新的研究结果，描述了植物如何嫁接，并为这一新兴领域的未来发展方向提供了见解。
For millennia, people have cut and joined different plants together through a process known as grafting. The severed tissues adhere, the cells divide and the vasculature differentiates through a remarkable process of regeneration between two genetically distinct organisms as they become one. Grafting is becoming increasingly important in horticulture where it provides an efficient means for asexual propagation. Grafting also combines desirable roots and shoots to generate chimeras that are more vigorous, more pathogen resistant and more abiotic stress resistant. Thus, it presents an elegant and efficient way to improve plant productivity in vegetables and trees using traditional techniques. Despite this horticultural importance, we are only beginning to understand how plants regenerate tissues at the graft junction. By understanding grafting better, we can shed light on fundamental regeneration pathways and the basis for self/non‐self recognition. We can also better understand why many plants efficiently graft whereas others cannot, with the goal of improving grafting so as to broaden the range of grafted plants to create even more desirable chimeras. Here, I review the latest findings describing how plants graft and provide insight into future directions in this emerging field.
