中國水仙NtSOC1基因克隆及亞細胞定位
[Abstract]:The cDNA of the homologous gene NtSOC1.NtSOC1 of anthesis related transcription factor (SOC1) was obtained by RACE and RT-PCR from Narcissus chinensis (Narcissus chinensis) as experimental material. The cDNA contained an open reading frame of 687bp encoding 228 amino acids. Bioinformatics analysis showed that the amino acid sequence of SOC1 homologous gene of NtSOC1 and Monocotyledonous plants was similar, and a highly conserved SOC1motif sequence was also found at the C-terminal, indicating that NtSOC1 belongs to the SOC1/TM3 subfamily gene. Fluorescence quantitative PCR analysis showed that the expression of NtSOC1 increased with flower bud differentiation and decreased at the end of flower bud differentiation, suggesting that NtSOC1 gene might be involved in flower bud differentiation of Narcissus chinensis. The NtSOC1 gene expression vector pCAMBIA1302-NtSOC1, was successfully constructed and transformed into onion epidermis by Agrobacterium tumefaciens for subcellular localization of the encoded protein. The results showed that the encoded protein of NtSOC1 gene was located in the nucleus and accorded with the subcellular localization characteristics of transcription factors. The results laid a foundation for further study of the biological function of NtSOC1 gene.
