Rootstock-scion exchanging mRNAs participate in the pathways of amino acids and fatty acid metabolism in cucumber under early chilling stress.

ABSTRACT: Cucumber (Cucumis sativus L.) often experiences chilling stress that limits their growth and productivity. Grafting is widely used to improve abiotic stress resistance by alternating a vigorous root system, suggesting there exists systemic signals communication between distant organs. mRNAs are reported to be evolving in fortification strategies by long-distance signaling when plants suffering from chilling stress. However, the potential function of mobile mRNAs alleviating chilling stress in grafted cucumber is still unknown. Here, the physiological changes, mobile mRNAs profiling, transcriptomic and metabolomic changes in above- and underground tissues of all graft combinations of cucumber and pumpkin responding to chilling stress were established and analyzed comprehensively.
