| Abstract: | Degenerate primers were designed according to the conserved regions of chalcone isomerase (CHI) from higher plants,and were used to amplify the cDNA fragment of CHI gene from Canna generalis Bailey. The 3' and 5' end of CHI gene were obtained by 3' RACE and TAIL-PCR respectively. The results showed that the cDNA of CHI gene from C. generalis was 678 bp encoding 226 amino acids,and high homology to CHI from other higher plants. |
