l-Glutamate activates salicylic acid signaling to promote stomatal closure and PR1 expression in Arabidopsis.

Physiologia plantarum - 1 Jan 2023

Tsuruda Toshihiko, Yoshida Riichiro

Abstract excerpt

Glutamate (l-Glu), an animal neurotransmitter, plays an essential role in plant signaling and regulates various plant physiological responses. We previously showed that l-Glu regulates stomatal closure in Arabidopsis via the glutamate receptor-like 3.5 gene (GLR3.5). Here, we showed that l-Glu activates salicylic acid (SA) signaling in Arabidopsis. l-Glu not only promoted stomatal closure but also triggered the...
