石蒜LrCMO基因的克隆及表達(dá)分析
[Abstract]:The full-length cDNA, of LrCMO gene was cloned from Lycoris (Lycoris radiata) by homologous cloning and RACE assay and its gene expression was analyzed. The results showed that the total length of LrCMO gene was 1 472 bp, and the open reading frame (ORF) encoded 427 amino acid residues. The predicted molecular weight of the encoded protein was 47.92 kD, and the theoretical isoelectric point was 5.72 kD, which was a stable hydrophobic protein with no transmembrane structure. The amino acids encoded by LrCMO gene were consistent with other plant CMO proteins and had the highest relationship with PdCMO, banana MaCMO and oil palm EgCMO. Real-time fluorescence quantitative PCR analysis showed that LrCMO was expressed in roots, bulbs and leaves, and the highest expression level was found in bulbs, and the relative expression of LrCMO was the highest in 12 h after treatment with polyethylene glycol (PEG). With the extension of treatment time, the relative expression of LrCMO gene decreased gradually to the control level.
