Synergistic Effect of Composite Chitosan/Phenylalanine Edible Coating on the Postharvest Bioactive Composition of Mandarin Fruit

Food Science &Nutrition, Volume 13, Issue 12, December 2025.
Chitosan/Phenylalanine (Chitosan/Phe) composite coating markedly enhanced the postharvest stability and biochemical integrity of mandarin fruit. This treatment effectively extended shelf life to 12 days at ambient conditions and 35 days under cold storage, while significantly increasing polyphenolic and flavonoid content and sustaining antioxidant ...

Targeting the “bitterness gene” by genome editing abolishes synthesis of bitter flavanones in citrus; prospects for new varieties and extended climates for cultivation

The Plant Journal, Volume 124, Issue 6, December 2025.
SUMMARY Bitterness in citrus fruit is conferred by flavanone‐neohesperidosides, whose accumulation is catalyzed by a single enzyme flavanone‐7‐O‐glucosides‐1,2‐rhamnosyltransferase (1,2RhaT), expressed in both leaves and fruit. To eliminate citrus bitterness, we used CRISPR/Cas9 genome editing to inactivate the 1,2RhaT gene in grapefruit (Citrus ...
