Transcriptome analysis of flowering regulation by sowing date in Japonica Rice (Oryza sativa L.)

Abstract Hybrid japonica cultivars, such as the Yongyou series, have shown high yield potential in the field in both the early and late growing seasons. Moreover, understanding the responses of rice flowering dates to temperature and light is critical for improving yield performance. However, few st...
