“…The genetic evidence showed that VvMYBPA1 not only activates PA branch genes, including VvLAR1 and VvANR , but also positively regulates the expression of VvCHI and VvF3’H at the upstream of flavonoid pathway ( Terrier et al., 2009 ). Consistent with the similar expression pattern as VvMYBPA1 in response to the high salt stress, VvMYBA1 , VvMYBA2 and VvNAC17 also positively target to the general flavonoid pathway ( Badim et al., 2022 ) - this might be a strategy to compensate the absence of the functions of VvMYB5a and VvMYB5b in grape suspension cells under salinity stress. Moreover, based on homology, we identified a number of potential flavonoid transcription factors whose expressions were NaCl dose-dependent in grape suspension cells, including MYB, RAV, NAC, LBD, ERF and WRKY family proteins.…”
