2.5　Analysis of repetitive sequences

Local BLASTn search of mtDNA against itself was performed using a cut-off e-value of 10—7(Altschul，1990).Repetitive sequences were analyzed by several programs，including REPuter，Tandem Repeats Finder and MIcroSAtellite(Benson，1999；Kurtz et al.，2001；Thiel et al.，2003).REPuter was applied to identify the forward，reverse，complement and palindromic sequences.Tandem Repeats Finder was used to find tandem repeats while MIcroSAtellite detected the microsatellite DNA(1～6bp).(https://www.daowen.com)
