Functional Characterization of OsCSN1 in the Agronomic Trait Control of Rice Seedlings Under Far-Red Light.

ABSTRACT: The COP9 signalosome (CSN) is a highly conserved multi-subunit protein complex, with CSN1 being its largest and most conserved subunit. The N-terminal function of CSN1 plays a pivotal and intricate role in plant photomorphogenesis and seedling development. Moreover, CSN is essential for far-red light-mediated photomorphogenesis in seedlings, but the function of OsCSN1 in seedling growth and development under far-red light conditions has not been determined. This study investigates the function of OsCSN1 under far-red light through phenotypic analysis of wild type and OsCSN1 mutant seedlings. Additionally, the effect of the N-terminal region of OsCSN1 on rice seedling growth and development was examined. The addition of exogenous hormone gibberellin (GA₃) and gibberellin s
