ABA signalling manipulation suppresses senescence of a leafy vegetable stored at room temperature

New article published in the Plant Biotechnology Journal about the important role of abscisic acid (ABA) in the control of postharvest senescence of a leafy vegetable like green cabbage (Brassica oleracea var. capitata). With the transcriptome analysis of cabbage leaves trated with ABA and a partial agonist of ABA (pyrabactin), this article shows a suppression of senescence of stored leaves, changes in the transcriptional regulation of glucosinolates metabolism and down‐regulations on biotic stress defence mechanisms. Thus, authors suggest a potential for manipulating ABA signalling for improving postharvest quality of leafy vegetables stored at ambient temperature.
