Nitrite, as well as the nitric oxide (NO) donor S-nitroso-N-acethylpenisilamine (SNAP), was found to increase the aperture of stoma on Vicia faba leaf peels. The results demonstrated here suggest that the nitrite-dependent NO production pathway would be involved in the signal transduction for stomatal movements.
