Root-to-shoot mobile mRNA CmoKARI1 promotes JA-Ile biosynthesis to confer chilling tolerance in grafted cucumbers

Abstract Pumpkin rootstock is commonly used to graft cucurbit crops, improving their ability to withstand stress. While the significance of systemic signals from rootstocks to scions is recognized, the role of root-to-shoot transported mRNAs remains understudied. Cucumber plants often face growth an...
