Model of VaPAT1 TF action during grape cold stress identified in this work. The model indicates that the cold stress-induced increase of VaPAT1 upregulates VaLOX3 expression (by forming a complex with IDD3) and increases JA accumulation, resulting in the transcriptional activation of stress-inducible genes and enhanced cold tolerance of grapevine. MeJA, methyl jasmonate.
