ABA mediates seasonal drought-induced citrate accumulation in citrus fruit through transcriptional and post-translational regulation of CsMADS1
Abstract Seasonal drought at fruit enlargement stage increases citrus fruit acidity, but the underlying mechanism remains incompletely understood. Here, CsMADS1, a MADS-box transcription factor, was identified as a positive regulator of abscisic acid (ABA)-induced citrate accumulation associated with seasonal drought in citrus fruit. CsMADS1 was upregulated by drought and ABA…
