ABSTRACT
According to ObgC gene sequences from Cyathula officinalis genomic data, the specific primers were designed, and a full-length CoObgC cDNA (2 226 bp) was obtained by polymerase chain reaction (PCR) and rapid amplification of cDNA ends (RACE) methord. Sequence alignment showed that CoObgC gene contained a 1 818 bp open reading frame (ORF) encoding 605 amino acids. Sequence analysis predicted that molecular weight of CoObgC protein was about 66.39 kDa, the academic isoelectric point was 5.35, and the protein was stable protein. Then multiple sequence alignment was applied to construct phylogenetic tree. The real-time fluorescence quantification PCR (RT-qPCR) demonstrated that a high expression level in leaf, followed by root and flower, the low transcription was in stem. The recombinant vector pCABIA2300-CoObgC was constructed and introduced into tobacco epidermal cells by agrobacterium-mediated transformation, green fluorescence was tested and targeted to chloroplast under a laser scanning confocal microscope. These findings will be helpful to lay a foundation for studying the structure and function of CoObgC gene, and elucidating C. officinalis molecular biology experiment.
