Abstract/OtherAbstract:
One 1.2 kbp long sequence was cloned by using PCR with primers that were designed from cDNA sequence of CsH1 gene (Genbank: EU716314) from tea plant (Camellia sinensis). According to the 1.2 kbp sequence, a 0.6 kbp sequence was isolated from tea plant genomic DNA using DNA Walking Method. Sequence analysis revealed that the 1.2 kbp sequence is a CsH1 gene consisting of 1 exon and 2 introns, the border of exton and intron sequences conforming to the GT-AG rule, and the 0.6 kbp sequence was found to be the promoter of CsH1 gene which contains basic promoter elements, TATA-box and CAAT-box. Abscisic acid responsiveness cis-acting element, elictor-responsive element, GA response element, light response cis-acting element and TC-rich repeats were also represented. To further study the activity of this promoter, the sequence was used to drive a GUS fusion gene in Agrobacterium-mediated transformation of tea plant somatic embryos, leaf discs and calli of tobacco (Nicotiana tabacum L.) where a high level of GUS expression was both observed in the tobacco calli and tea plant somatic embryos. These results suggest that the CsH1 gene promoter isolated is capable of conferring nuclear gene expression.
