Dissecting postharvest chilling injury through biotechnology.

Area of Science:

• Plant physiology
• Postharvest biology
• Biotechnology

Background:

• Refrigeration is commonly used to extend the shelf life of fruits and vegetables.
• However, low temperatures can damage produce from tropical and subtropical regions, a phenomenon called postharvest chilling injury (PCI).
• PCI leads to accelerated spoilage and significant economic losses.

Purpose of the Study:

• To review the current understanding of the cellular and molecular mechanisms underlying PCI.
• To highlight advances in biotechnological strategies for mitigating PCI symptoms.
• To identify knowledge gaps for developing effective solutions to PCI.

Main Methods:

• Literature review of scientific studies on postharvest chilling injury.
• Analysis of cellular and molecular processes involved in PCI.
• Evaluation of biotechnological approaches for ameliorating PCI.

Main Results:

• Identified key cellular and molecular pathways affected by chilling temperatures.
• Summarized progress in biotechnological interventions to reduce PCI.
• Highlighted the paradoxical effect of refrigeration on certain produce quality.

Conclusions:

• Understanding PCI mechanisms is crucial for reducing postharvest loss.
• Biotechnological approaches show promise in preserving chilling-sensitive produce.
• Further research is needed to bridge knowledge gaps and develop comprehensive solutions for PCI.
