Molecular characterization of a CONSTANS gene from Sapium sebiferum (L.) Rxob
چکیده انگلیسی
Sapium sebiferum (L.) Roxb [S. sebiferum L.] is not only one of the most important economic woody oil trees, but is also a significant traditional herbal medicine in China. The CONSTANS (CO) gene is a key regulator of the long day-dependent flowering pathway in Arabidopsis and other plants. To gain insight into the role of CO in woody oil trees, SsCO from S. sebiferum L. was isolated and characterized in this study. The corresponding SsCO protein, with 340 amino acid residues, included two putative zinc finger motifs B-Box1 and B-Box2 in the N-terminal region and a conserved CCT domain in the C-terminal region. SsCO expression was high in flowers and exhibited distinct circadian regulation. In addition, SsCO had a transcriptional activation effect in yeast strains. Moreover, heterologous expression of SsCO complemented the late-flowering phenotype of the Arabidopsis CO mutant co-1. These results indicate that SsCO is a transcription factor and may regulate the photoperiodic flowering time and SsCO is regulated by circadian rhythms in Sapium sebiferum L.
