To uncover the molecular processes related to the ability of early varieties to withstand mealiness, postharvest and genome\u2010wide RNA\u2010seq assessments were performed in two early and two late varieties. Differences in juice content and ethylene biosynthesis were detected among early and late season fruits that became mealy after exposed to prolonged chilling. Principal component and data distribution analysis revealed that cold\u2010stored late variety fruit displayed an exacerbated and unique transcriptome profile when compared to any other postharvest condition. A differential expression analysis performed using an empirical Bayes mixture modeling approach followed by co\u2010expression and functional enrichment analysis uncover processes related to ethylene, lipids, cell wall, carotenoids and DNA metabolism, light response, and plastid homeostasis associated to the susceptibility or resistance of <jats:styled-content style=\"fixed-case\"><jats:italic>P. persica<\/jats:italic><\/jats:styled-content> varieties to chilling stress.
