Abstract:
Ready-to-eat fresh cut produce are exposed to pre- and postharvest abiotic stresses during the production
chain. Our work aimed to identify stress responsive genes as new molecular markers of quality that
can be widely applied to leaves and fruits and easily determined at any stage of the production chain.
Stress responsive genes associated with quality losses were isolated in rocket and melon fresh-cut produce
and their expression levels analyzed by quantitative real time PCR (qRT-PCR) at different time
points after harvest at 20 C and 4 C. qRT-PCR results were supported by correlation analysis with physiological
and biochemical determinations evaluated at the same conditions such as chlorophyll a fluorescence
indices, total, reducing sugars, sucrose, ethylene, ascorbic acid, lipid peroxidation and reactive
oxygen species. In both species the putative molecular markers increased their expression soon after
harvest suggesting a possible use as novel and objective quality markers of fresh-cut produces.
