Understanding the mechanisms of chilling injury in bell pepper fruits using the proteomic approach

► The proteome profile of chilled bell pepper fruits was determined. ► Microscopic, physiological and metabolic changes induced by CI were studied. ► The main alterations are linked to redox homeostasis and carbohydrate metabolism. ► Enolase and GAPDH are revealed as possible key proteins in the CI development. ► First evidence at protein level is provided that cyMDH is involved in abiotic stress.
