Multi-omics analysis unveils crucial networks underlying jasmonate-regulated diurnal floret opening and closure in rice

Diurnal floret opening and closure (DFOC) is essential for rice reproductive development and hybrid breeding, yet transcriptional dynamics and underlying regulatory networks remain poorly characterized. Here, we conducted high-temporal-resolution transcriptomic analyses of lodicules to dissect DFOC regulatory networks in two japonica rice cultivars. Through multi-omics analysis, genetic and molecular validation, we uncovered OsMYC2-centric networks and novel regulators in DFOC control.
