Phosphorylated AtNRT1.1 confers early flowering and high reproductive yield in Arabidopsis.

Plant physiology and biochemistry : PPB - 1 Apr 2026

Yu Jianyuan, Wu Zheng, Shan Xiaoyi

Abstract excerpt

Nitrate, the predominant form of nitrogen in the soil, functions as a nutrient and signal to modulate the reproductive growth of plants such as flowering and grain yield. The nitrate transceptor ARABIDOPSIS THALIANA NITRATE TRANSPORTER 1.1 (AtNRT1.1) has two modes of nitrate transport and signaling that are governed by Thr-101 (T101) phosphorylation. Here, we used WT, chl1-5, T101A, and T101D Arabidopsis plants...
