Molecular Mechanism of Oryza sativa L. Under Long Day Regime Based on Transcriptome Analysis

The growth of rice (Oryza sativa L.) is affected by long days, which occur throughout the year in southern China, leading to a sharp decline in rice varieties and yields. In order to conduct adaptive genetic breeding research on rice, it is urgent to understand the long days response mechanism of rice. This study used RNA-seq technology to analyze rice under long day conditions and found that RNA, Ehd1, chlorophyll a/b binding protein, were identified as key genes or proteins under long day conditions. MAPK is closely related to long day conditions. This study provides a unique theoretical basis for long-term research and genetic breeding of rice by screening key genes related to the photoperiod.
