γ‑Aminobutyric Acid Alleviates Discoloration of Or Mutant Cauliflower via BoMYB24-Mediated Transcriptional Regulation of BoLCYB

Orange (<i>Or</i>) mutant cauliflower is prone to discoloration during storage, which affects its commercial value. γ-Aminobutyric acid (GABA) treatment can effectively delay the discoloration of <i>Or</i> mutant cauliflower during storage; however, its mechanism of action remains unclear.
Description
Here, we aimed to identify key genes and candidate transcription factors associated with discoloration in <i>Or</i> cauliflower treated with GABA during storage.
Transcriptome analysis revealed that GABA regulated <i>BoLCYB</i>, with BoMYB24 identified as the candidate transcription factor in this pathway. BoMYB24 binds the <i>BoLCYB</i> promoter through the MBS-1 motif. Additionally, under GABA treatment, the transcriptional activation effect of BoMYB24 on <i>BoLCYB</i> is further enhanced. <i>BoMYB24</i> overexpression increases <i>BoLCYB</i> expression, leading to a large accumulation of β-carotene in chromoplasts and promoting the accumulation of auxin and abscisic acid.

Furthermore, under GABA treatment, the transcription level of BoMYB24 was markedly upregulated, thus delaying the postharvest discoloration of <i>Or</i> mutant cauliflower by positively regulating <i>BoLCYB</i>.
