| 摘 要： | The outbreak of SARS sets an urgent task to reveal the origin of human SARS-CoV, i.e. its relation to other known species of coronavirus, and to trace the genetic variation in the spreading process of SARS. Partial answer to the problem may be obtained from phylogenetic analy-sis of available genomes. We call a phylogenetic tree of different species of coronavirus including the human SARS-Cov a CoV Tree and that of different isolates of SARS-CoV a SARS Tree. CoV trees have been c…

| Abstract: | Phylogenetic tree of coronaviruses (CoVs) in-cluding the human SARS-associated virus is reconstructed from complete genomes by using our newly developed K- string composition approach. The relation of the human SARS-CoV to other coronaviruses, i.e. the rooting of the tree is suggested by choosing an appropriate outgroup. SARS-CoV makes a separate group closer but still distant from G2 (CoVs in mammalian host). The relation between different isolates of the human SARS virus is inferred by first constructing an ultrametric distance matrix from counting sequence variations in the genomes. The resulting tree is consistent with clinic relations between the SARS-CoV isolates. In addition to a larger variety of coronavirus ge-nomes these results provide phylogenetic knowledge based on independent novel methodology as compared to recent phylogenetic studies on SARS-CoV. |
