Postharvest decay in fruits, primarily caused by pathogenic fungi, remains a major obstacle to agricultural sustainability and food security. Despite advances in fungicides and storage technologies, losses remain substantial, especially in developing countries. The challenge is exacerbated by the limitations of fungicides, including pathogen resistance and environmental concerns, which underscore the pressing need for sustainable solutions.
Researchers from Tianjin University of Science and Technology have directed their efforts towards finding such solutions. They published a study in Horticulture Research on June 19, 2024, focusing on an innovative approach to bolster fruit defenses against decay. The study is a significant step forward in the quest for sustainable agricultural practices.
Titled "Chemical induction of DNA demethylation by 5-Azacytidine enhances tomato fruit defense against gray mold," the study delves into how inhibiting DNA methylation can trigger defense mechanisms in tomatoes. This approach represents a groundbreaking method to combat postharvest fungal infections, offering a potential alternative to traditional fungicides.
By examining the effects of DNA demethylation, the researchers present a novel strategy to enhance tomato fruit defense against gray mold. This method not only addresses the issue of pathogen resistance but also aligns with environmental conservation efforts, marking a promising advancement in the field of agricultural science.
