L-Met activates Arabidopsis GLR Ca2+ channels upstream of ROS production and regulates stomatal movement.

January 13, 2017

Okuma, Munemasa, and Murata collaborated with Dr. Kwak (DGIST, Korea) and Dr. Pei (Duke, NC) to clarify that plant glutamate receptor homologs formed Ca2+ channels activated by L-methionine at physiological concentrations and regulate stomatal apertures and plant growth.
The findings suggest that administration of methionine easily improves drought stress tolerance of plants. The administration of methionine is useful because methionine is a cheap amino acids, meaning it is economical and harmless.
