Transcriptomic analysis elaborates the resistance mechanism of grapevine rootstocks against salt stress

In this study, we selected 6 varieties with large differences in salt stress tolerance to analyze the global expression of response genes through RNA sequencing (RNA-seq) in an attempt to identify the key genes as well as response pathways under salt stress, including salt-tolerant varieties 3309C (3309C, 3309C-P1, 3309C-P2), 520A (520A, 520A-P1, 520A-P2), 1103P (1103P, 1103P-P1, 1103P- P2), and non-salt-tolerant varieties 5BB (5BB, 5BB-P1), 101-14 (101-14, 101-14-P1), Beta (Beta, Beta-P1). These results provide genetic information related to salt stress, which can provide a basis for the further development and evaluation of comprehensive stress-resistant grape rootstock varieties.
