A multi-layered regulatory model uncovers the central role of OsPRR37 in coordinating multiple agronomic traits.

ABSTRACT:

Background

The plant circadian clock is crucial for regulating developmental and metabolic processes, enabling crops to adapt to environmental changes and maintain high productivity. In rice, the clock gene OsPRR37 plays a pivotal role in photoperiod sensitivity and the regulation of yield-related traits. However, the complete regulatory network of OsPRR37 remains largely unexplored.

Results

This study utilized an integrated multi-omics approach, combining transcriptome profiling, DNA affinity purification sequencing (DAP-seq), and protein-protein interaction (PPI) mapping to construct a multi-layered regulatory model of OsPRR37. CRISPR/Cas9 knockout lines showed significant changes in flowering time, plant height, panicle architecture, and spikelet number. Transcriptome ana
