DNA barcoding analysis and phylogenetic relationships of tree species in tropical cloud forests.

ABSTRACT: DNA barcoding is a useful tool for species identification and phylogenetic construction. But present studies have far reached a consistent result on the universality of DNA barcoding. We tested the universality of tree species DNA barcodes including rbcL, matK, trnH-psbA and ITS, and examined their abilities of species identification and phylogenetic construction in three tropical cloud forests. Results showed that the success rates of PCR amplification of rbcL, matK, trnH-psbA and ITS were 75.26% ± 3.65%, 57.24% ± 4.42%, 79.28% ± 7.08%, 50.31% ± 6.64%, and the rates of DNA sequencing were 63.84% ± 4.32%, 50.82% ± 4.36%, 72.87% ± 11.37%, 45.15% ± 8.91% respectively, suggesting that both rbcL and trnH-psbA are universal for tree species in the tropical cloud forests. The success rates of sp
