The nitrate transporter AtNRT1.1 (CHL1) functions in stomatal opening and contributes to drought susceptibility in Arabidopsis.

The Plant cell - 1 Jan 2003

Guo Fang-Qing, Young Jared, Crawford Nigel M

Abstract excerpt

The movement of guard cells in stomatal complexes controls water loss and CO(2) uptake in plants. Examination of the dual-affinity nitrate transporter gene AtNRT1.1 (CHL1) revealed that it is expressed and functions in Arabidopsis guard cells. CHL1 promoter-beta-glucuronidase and CHL1 promoter-green fluorescent protein constructs showed strong expression in guard cells, and immunolocalization experiments with...
