This chapter aims to review the biology of grafting and the factors influencing graft compatibility, focusing on the molecular and physiological aspects affecting graft development and success in herbaceous and woody plants. Recently, genes known to be involved in wounding/healing, vascular differentiation, programmed cell death, reactive oxygen species production/elimination, phenylpropanoid pathways and cell-wall biosynthesis, have been identified during graft union development and graft incompatibility reactions. More research is needed to investigate how to overcome graft incompatibility. The use of auxins, ethylene blockers, abscisic acid or its analogues, gibberellins and compounds with antioxidation properties, as well as inhibitors of enzymes involved in the phenylpropanoid pathway, are all candidates of interest.Read less <
