Phosphorus Alters the Metabolism of Sugars and Amino Acids in Elite Wheat Grains.

ABSTRACT: Phosphorus supply significantly influences starch and amino acid accumulation in wheat grains, yet the mechanisms coordinating sugar-amino acid metabolic crosstalk under differential phosphorus availability remain elusive. To address this knowledge gap, we conducted a controlled trial on phosphorus supplementation using wheat (Triticum aestivum L. cv. Xindong 20) with three treatments: P0 (0 kg·ha^-1, phosphorus deficiency), LP (105 kg·ha^-1, normal phosphorus), and HP (210 kg·ha^-1, phosphorus excess). Seed samples were collected at 7, 14, and 21 days post-anthesis (DPA). This design enabled a systematic analysis of how phosphorus availability modulates the metabolic relationship between amino acids and sugars during grain development. Proteomic profiling of
