New Rice Gene 'Chilling Phoenix' Enhances Cold Tolerance and Nitrogen Efficiency
Global climate change has increased the frequency of regional cold spells, causing substantial yield losses and even crop failure. Meanwhile, excessive nitrogen fertilizer use in agriculture has increased non-point-source pollution. Improving both stress resilience and nitrogen use efficiency has therefore become a major challenge for sustainable crop production.
Scientists have identified a novel rice gene module, dubbed 'Chilling Phoenix' (CHPO), that significantly improves the plant's resilience to cold spells and its efficiency in utilizing nitrogen. This discovery is crucial for sustainable agriculture, especially in the context of increasing global climate change and the environmental impact of excessive nitrogen fertilizer use. CHPO dynamically adjusts its function based on environmental conditions: it enhances cold tolerance during chilling stress and promotes nitrogen uptake and growth during recovery periods. The research team utilized advanced genetic mapping techniques to identify CHPO and its superior allele, CHPOjap, which originated from wild rice and was selected during domestication. This gene offers a promising solution for reducing crop yield losses due to cold weather and minimizing agricultural pollution.
The discovery of the CHPO gene offers a potential breakthrough for improving rice crop resilience to climate change and reducing the environmental impact of agriculture.
