CO₂ Elevation Accelerates Phenology and Alters Carbon/Nitrogen Metabolism vis-a-vis ROS Abundance in Bread Wheat.

ABSTRACT: Wheat is an important staple food crop of the world and it accounts for 18-20% of human dietary protein. Recent reports suggest that CO₂ elevation (CE) reduces grain protein and micronutrient content. In our earlier study, it was found that the enhanced production of nitric oxide (NO) and the concomitant decrease in transcript abundance as well as activity of nitrate reductase (NR) and high affinity nitrate transporters (HATS) resulted in CE-mediated decrease in N metabolites in wheat seedlings. In the current study, two bread wheat genotypes Gluyas Early and B.T. Schomburgk differing in nitrate uptake and assimilation properties were evaluated for their response to CE. To understand the impact of low (LN), optimal (ON) and high (HN) nitrogen supply on plant growth, phenology, N
