Baiyan 2
cultivar
We take Baiyan 2, a light-sensitive variety, as the research object to investigate the molecular mechanism of flowering regulation under long-day photoperiod inducement. Morphological observation of SAM showed that induction of long-day photoperiod was necessary for flowering of oat. By transcriptome sequencing analysis, we found that a number of DEGs were identified at different stages of oat photoperiod induction, indicating that the long-day photoperiod affects many metabolic processes and signaling pathways in oat, in particular, at the late flowering stage of oat, thus producing flowering signals to promote flowering. By GO enrichement analysis, various hormone pathways, including CK, ABA, AUXIN, et, ja and GA, are the main flowering regulatory pathways in oat response to photoperiod inducement. The KEGG analysis indicate the importance the circadian clock-plant and Photosynthesis-antenna proteins pathways. In addition, some genes involved in sucrose synthesis and metabolism and circadian rhythm, and transcription factors particaped in various flowering pathways are associated with long-day-induced flowering. This study laid a foundation for further research on the mechanism of oat flowering, and also provided an important reference for oat molecular breeding.
