OsBADH1-OsBADH2 Double Mutants Increase 2-Acetyl-1-Pyrroline Accumulation and Alter GABA-Associated Abiotic Stress Responses in Rice.

Genes - 18 May 2026

Abstract excerpt

BACKGROUND/OBJECTIVES: Rice fragrance is mainly determined by 2-acetyl-1-pyrroline (2-AP), which is negatively regulated by OsBADH2. However, the contribution of its paralog OsBADH1 to aroma-associated metabolism and GABA-linked abiotic stress responses remains unclear. This study investigated whether simultaneous disruption of OsBADH1 and OsBADH2 further enhances 2-AP accumulation while affecting stress...
