New approaches to the biology of stomatal guard cells.

Plant & cell physiology - 1 Feb 2014

Negi Juntaro, Hashimoto-Sugimoto Mimi, Kusumi Kensuke, Iba Koh

Abstract excerpt

CO2 acts as an environmental signal that regulates stomatal movements. High CO2 concentrations reduce stomatal aperture, whereas low concentrations trigger stomatal opening. In contrast to our advanced understanding of light and drought stress responses in guard cells, the molecular mechanisms underlying stomatal CO2 sensing and signaling are largely unknown. Leaf temperature provides a convenient indicator of...
