[Ming-Hsiun Hsieh] Glutamate triggers defense responses and promotes root hair elongation in Arabidopsis
POST:
A hypothetical model of Glu–induced defense responses and root hair elongation. When glutamate (Glu) is supplied as the sole nitrogen source, it not only functions as a growth-promoting metabolite upon entering the cell but also acts as a signaling molecule to activate defense responses and root hair elongation.
Recent research from Dr. Ming-Hsiun Hsieh’s laboratory has revealed that exogenous glutamate (Glu) serves dual functions as both a nitrogen source and a danger signal, and can influence plant growth, immune responses, and root hair development in Arabidopsis through distinct hormonal and transcriptional regulatory pathways.
This study was primarily conducted by Ms. Yi-Jie Hung, a master’s student in the collaborative graduate program between IPMB and National Central University, under the joint supervision of Professors Ming-Hsiun Hsieh and Ching-Hui Yeh. The findings have been published in the journal Plant Physiology.
