Although NDH function has been extensively characterized under controlled conditions, NDH\u2010deficient mutants often show only subtle phenotypes in such environments, leaving its physiological importance to photosynthesis in plants grown under naturally fluctuating field conditions poorly understood. Here, we evaluated growth, yield, and photosynthetic performance of NDH\u2010deficient rice cultivated in outdoor fields. Mutant plants exhibited reduced biomass accumulation and grain yield compared with wild type (WT). Detailed physiological analyses in field\u2010grown plants revealed that NDH deficiency markedly decreased PSI electron transport and CO\n                    <jats:sub>2<\/jats:sub>\n                    assimilation, particularly under low temperature and sub\u2010saturating irradiance.

These findings demonstrate that NDH\u2010dependent CET plays a crucial role in sustaining crop productivity in field environments by stabilizing photosynthetic efficiency under sub\u2010optimal conditions through maintaining PSI redox balance.\n
