摘要： Copper is an essential trace element in grapevine growth, and lack of it will cause damage to grapevines. However, there are few studies on the physiological changes and regulatory mechanisms of chronic copper deficiency stress in grapevines. The 'Shine Muscat' ('SM') seedlings were treated with Hoagland nutrient solution without copper ions to explore the adaptive response and regulatory mechanism for 35 days. Firstly, it was found that 'SM' grapevines were indeed affected by copper deficiency stress through the leaf symptoms and physiological data. Then, 657 up-regulated and 527 down-regulated differentially expressed genes (DEGs) and 72 differentially accumulated metabolites (DAMs, 31 up-regulated and 41 down-regulated) were identified between control and copper deficiency treatment. Copper ion transportation, photosynthetic pathway, antioxidant system, flavonoid metabolism, and phytohormone metabolism were identified as the primary response systems in 'SM' grapevines. Several genes, including FRO4, ABCs, CHLP, APX, GPX, and PK played a crucial role in the response of 'SM' grapevine to copper deficiency stress. Furthermore, there were notable differences in copper uptake and transportation, chlorophyll degradation, flavonoid synthesis and metabolites, and ABA content between copper deficiency and excess stress. These results will be beneficial to gain insights with copper deficiency regulation and stress-responsive strategies in grapevines.
