Integrated multiomics analysis reveals the molecular mechanism of light intensity-enhanced healing in cotyledon-less splice grafted watermelon.

ABSTRACT: Grafting in watermelon using traditional methods often causes rootstock regrowth, increasing labor demand and production costs. Although cotyledon-less splice grafting eliminates regrowth by excising meristem tissue, its success rate has consistently been lower. Here, we developed a novel cotyledon-less splice grafting methodology that achieved high survival rates by modulating pre-grafting light intensities from 100 to 300 μmol·m^-2·s^-1 for scion and rootstock, generating four experimental groups: high-light intensity scion/high-light intensity rootstock (HS/HR), high-light intensity scion/low-light intensity rootstock (HS/LR), low-light intensity scion/high-light intensity rootstock (LS/HR), and low-light intensity scion/low-light intensity rootstock (LS/LR).
