Identification and Characterization of AUXIN Response Factor Gene Family Reveals Their Regulatory Network to Respond the Multi-Hormones Crosstalk during GA-Induced Grape Parthenocarpic Berry.

ABSTRACT: Exogenous gibberellin (GA) was widely used to improve berry quality through inducing parthenocarpic seedless berries in grapes. We revealed that auxin response factors (ARFs), the key transcription factors in response to auxin, might respond to GA involving modulation of grape parthenocarpy. However, the underlying molecular mechanism in this process remains yet unclear. Here, a total of 19 VvARF members were identified in the ovaries during GA-induced grapes' parthenocarpy. Interestingly, almost all members were GA-responsive factors, of which 9 could be classified in plant hormone signal transduction (KO04075) and involved in the tryptophan metabolic pathway (K14486). Moreover, VvARFs were predicted to have 310 interacted proteins involved in 19 KEGG pathways. Of them, 32 interacted prot
