Molecular advances in rootstock-scion interaction in grapevine
In grapevine, grafting is a worldwide used technique employed to confer resistance to pests and diseases, to improve abiotic stress tolerance and to control plant vigour and some qualitative traits. Despite the relevance of rootstock, knowledge of the molecular mechanisms implicated in the rootstock-scion interaction still has many gaps. Only, recently, some experiments have been performed to investigate the effects of grafting technique, different soils and rootstocks on scion at transcriptomic level. This work reviews the most relevant findings in this field. These recent advances open a new perspective for a molecular interpretation about the interaction between scion and rootstock as well soil substrates.
