Schematic representation of the physiological and molecular mechanisms of nitrogen alleviating drought stress. Parts with a red background indicate upregulated genes, while those with a blue background indicate downregulated genes. Arrows represent regulatory relationships, with dashed arrows signifying that the relationship lacks direct evidence in this study and is considered speculative.
