High crop yields require adequate nutrients, particularly nitrate (N) and phosphorus (P). Identifying regulators for efficient N-P utilization is critical in wheat. To explore interactions, we analyze root transcriptomes under varying supplies identify TaTCP6 as a potential regulator. Nitrate-stimulated directly triggers the expression of genes related to nitrogen utilization. competes with TaSPX1/4 release TaPHR2, also interacts TaPHR2 enhance transactivation capacity downstream genes. Thus, through dual roles TaTCP6, TCP6-SPX-PHR2 module activates starvation response (PSR) Inhibiting reduces N P absorption, negatively impacting yield, while overexpressing increases grain yield. Notably, overexpression TaSPX1 suppresses genes, especially low conditions. In conclusion, our findings highlight role coordinating propose strategy reduce fertilizer inputs sustainable agriculture.
