Glycolysis dominates over photorespiration in governing oxalate accumulation in rice.

Plant physiology - 2 Jul 2026

Abstract excerpt

Oxalate is widely distributed and serves various functional roles in plants. However, its biosynthetic pathway and regulatory mechanisms remain poorly defined. In this study, we further investigated the mechanism of oxalate accumulation using rice (Oryza sativa) CRISPR-Cas9-generated nitrate reductase (NR) and nitrite reductase (NiR) mutants, combined with different treatments. Both NR and NiR mutants exhibited...
