Abstract

Hairy roots were induced from Korean ginseng (Panax ginseng C. A. Meyer) root explants and studied for their gene expression. A total of 3,000 ESTs (expressed sequence tags) from ginseng hairy root were determined and about 2,700 ESTs have a length of readable sequence, which result in 1,352 unique ESTs sequences. The 879 ESTs showed significant similarities to known nucleotide or amino acid sequences in other plant species, which were divided into eleven categories depending upon gene function. The remaining 473 sequences showed no significant matches, which are likely to be transcripts or to be matched to other organisms. The results indicated that the analysis of the ginseng hairy root ESTs by partial sequencing of random cDNA clones may be an efficient approach to isolate genes that are functional in ginseng root in a large scale. Our extensive EST analysis of genes expressed in ginseng hairy root not only contributes to the understanding of the dynamics of genome expression patterns in root organ but also adds data to the repertoire of all genomic genes.
