The Dark Side of Stress Response: Night Temperature Regimes Drive Distinct Abiotic Pathways in Legumes.

ABSTRACT: Global warming increases night temperatures more strongly than day temperatures. Recent evidence indicates that the effect of night temperature on plant physiology is independent of daytime conditions, suggesting distinct stress tolerance mechanisms. Legume crops, vital to sustainable agriculture, are particularly vulnerable to abiotic stresses, resulting in yield instability. Developing cultivars with round-the-clock stress tolerance requires an understanding of the mechanisms for nighttime abiotic stress tolerance. Unfortunately, data on nighttime abiotic stress response remain limited, particularly for legumes. This review examines the current understanding of nighttime versus daytime abiotic stress response in major crop legumes. Our analysis reveals that high night temperatures primar
