Research Progress on Molecular Regulation Mechanism in Plant Grafting
As one of the common artificial propagation methods of plants,grafting has been widely used in the research of breeding improved varieties,improving Crop Agronomic Characters and enhancing plant stress resistance in recent years.There exists complex interactions in the process of plant grafting,whether it is the gene expression change at the scion healing area,or the absorption and regulation of the mineral ions by grafted plants,or the long-distance transportation of the genetic material between the rootstock and scion,revealing its regulatory mechanism is of great significance for improving the success rate of grafting techniques and selecting suitable anvil and ear combinations.The study reviews recent advances in molecular regulation mechanism of plant grafting,and summarized the mainstream viewpoints.The study mainly analyzes and summarizes the regulatory factors from three aspects:plant hormones,mineral elements and gene molecules,and looks forward to the direction of this field in the future,so as to provide some references and suggestions for the research of grafting mechanism.
