Characterization of OsCAF1 Protein Function in Rice Response to Thermal Stress.

ABSTRACT: Heat stress is a critical environmental challenge that disrupts rice growth, development, and productivity and poses a significant threat to global food security. The CCR4-NOT protein complex, particularly its CCR4-associated factor 1 (CAF1) subunit, plays a crucial role in the dynamic regulation of gene expression by mediating mRNA de-adenylation, a key step in mRNA degradation and turnover. However, the specific function of OsCAF1 proteins under heat stress in rice remains poorly understood. In this study, we investigated the dynamic subcellular localization of OsCAF1A in response to elevated temperatures and its role in heat stress tolerance. Under normal conditions, OsCAF1A is diffusely localized to the cytoplasm. However, OsCAF1A predominantly localizes to processing bodies (PBs) unde
