Overexpression of cytosolic glutamine synthetase. Relation to nitrogen, light, and photorespiration.

Plant physiology - 1 Jul 2002

Oliveira Igor C, Brears Timothy, Knight Thomas J, Clark Alexandra, Coruzzi Gloria M

Abstract excerpt

In plants, ammonium released during photorespiration exceeds primary nitrogen assimilation by as much as 10-fold. Analysis of photorespiratory mutants indicates that photorespiratory ammonium released in mitochondria is reassimilated in the chloroplast by a chloroplastic isoenzyme of glutamine synthetase (GS2), the predominant GS isoform in leaves of Solanaceous species including tobacco (Nicotiana tabacum). By...
