ABA influences color initiation timing in P. avium L. fruits by sequentially modulating the transcript levels of ABA and anthocyanin-related genes

In sweet cherry, as in most non-climacteric species, abscisic acid (ABA) plays a major role the control of fruit ripening and color development. Although ABA treatment cherry fruits has been reported to upregulate anthocyanin pathway-related genes or genes, temporality molecular physiological events occurring during development these initiation are lacking this species. work, we analyzed variations Index Absorbance Difference (IAD), maturity index, total anthocyanins along with changes transcript abundance from light green red stages. PavNCED1 signaling upregulated when transitioned pink stage, whereas transcripts increased together increases content IAD, suggesting sequentiality Additionally, applied at planta advanced content, yielded darker harvest. These were accompanied by accumulation genes. This confirms that is central player cherries, associated involved homeostasis signaling, which followed up-regulation
