Rootstock secrets: how engineered walnuts combat drought through grafting
Chinese Academy of SciencesA cutting-edge study has revealed how genetic signals from rootstocks influence drought resistance in grafted walnut trees. Researchers found that by modifying the JrGA20ox1 gene in rootstocks, they could significantly enhance the trees' ability to cope with water scarcity. The study demonstrates a powerful new method for improving agricultural resilience to climate change, offering hope for sustaining walnut production under increasingly challenging environmental conditions.
