Research progress on molecular mechanism of rootstock-scion interaction in plant grafting
Grafting is an artificial breeding technology with high research values.To improve the survival rate of grafted seedlings and grafting technology,the molecular mechanisms of rootstock-scion interac-tion were studied by many researchers.In this paper,we reviewed the regulatory mechanisms of signal molecule transport in plant grafting,summarized the genetic effects(including epigenetics and differential expression of genes between rootstock and scion)after plant grafting and introduced research progress on the molecular mechanism of rootstock-scion interaction.At the same time,we also proposed the re-search fields on the molecular mechanism of rootstock-scion interaction in the future.The paper provided new ideas for further research on the molecular mechanism of Dlant araftina.
