Since, the curve contains the information carried by the given sequence, DNA sequences could be analyzed systematically. In this study, the Foot and Mouth Disease Virus (FMDV) was analyzed by the Z-curve Method. This research concludes that all serotypes FMDV have a close consanguinity but each has its own characteristic by contrast, the three South African serotypes have a much closer affinity. FMDV have three A + T-rich regions and two G + C-rich regions. The most variable regions of FMDV lie in protein coding areas. And the non-coding region is very conservative. O serotype FMDV is most variable compared with A and Asia1 serotype. Those O serotype FMDV in buffalo and goat have a mutation trend. Compared with host, geographic location have a grater influence on FMDV mutation. The A serotype FMDV strains occurred in India after 2002 are more stable and have a closer phylogenetic relationships compared with the Asia1 strains which were prevalent before 2002. In general, Z-curve Method shows a widely application prospect in the areas of life sciences. Such as gene sequence, molecular epidemiology, homology, evolution, phylogenetic relationships and genetic diversity analysis. ER -
