Arabidopsis HT1 kinase controls stomatal movements in response to CO2.

Nature cell biology - 1 Apr 2006

Hashimoto Mimi, Negi Juntaro, Young Jared, Israelsson Maria, Schroeder Julian I, Iba Koh

Abstract excerpt

Guard cells, which form stomata in leaf epidermes, sense a multitude of environmental signals and integrate this information to regulate stomatal movements. Compared with the advanced understanding of light and water stress responses in guard cells, the molecular mechanisms that underlie stomatal CO(2) signalling have remained relatively obscure. With a high-throughput leaf thermal imaging CO(2) screen, we report...
