Boosting lemon immunity: a gene unlocks resistance against viral threats
Chinese Academy of SciencesResearchers have uncovered how the gene ClGDPD1 strengthens Eureka lemon's defense against citrus yellow vein clearing virus (CYVCV). By facilitating the accumulation of sn-glycerol-3-phosphate (G3P), ClGDPD1 triggers systemic immune responses that significantly reduce viral load and disease symptoms. This study demonstrates that boosting G3P levels, either genetically or through external treatment, improves plant resistance. Understanding this mechanism offers promising strategies for protecting citrus crops from devastating viral infections, ensuring agricultural productivity and fruit quality. The findings also provide insights into how lipid metabolism pathways contribute to plant immunity, paving the way for broader applications in developing disease-resistant crops.
