In this study, we analyzed GABA shunt-related amino acids [glutamate (Glu), alanine (Ala), and GABA] and tricarboxylic acid (TCA)-cycle-related organic acids (pyruvate, citrate, α-ketoglutarate, succinate, fumarate, and malate) in rice, under dark and anaerobic conditions, to investigate the role of GABA in rice germination. The change in the GABA content before and after germination was compared using 2 cultivars selected from 18 varieties of Korean rice. Correlation anal. indicated that the metabolism of GABA in germinating rice might be related to Ala metabolism In a two-way stress study, GABA content was found to be pos. related to TCA-cycle organic acid contents (α-ketoglutarate, succinate, fumarate, and malate) but show a neg. relation with GABA shunt-related amino acid contents (Glu, Ala). In the dark, accumulation of TCA-cycle organic acids was observed, but Glu and Ala levels were reduced. GABA treatment (1 mM) in dark conditions produced TCA-cycle organic acids at levels similar to those in light conditions. In anaerobic conditions, TCA-cycle-related compounds accumulated at a high level, but Glu and Ala were remarkably reduced compared with normal conditions. As a result, GABA shunt is connected with TCA-cycle organic acids, but not amino acids. In conclusion, the present research suggests that GABA, accumulated in certain stress conditions, supplies organic acids such as succinate to the TCA cycle.
