cord-335155-x9az3twa	Qi, Zhen	Phylogeny of SARS-CoV as inferred from complete genome comparison	2003		.txt	text/plain	1616	97	59	SARS-CoV, as the pathogeny of severe acute respiratory syndrome (SARS), is a mystery that the origin of the virus is still unknown even a few isolates of the virus were completely sequenced. To explore the genesis of SARS-CoV, the FDOD method previously developed by us was applied to comparing complete genomes from 12 SARS-CoV isolates to those from 12 previously identified coronaviruses and an unrooted phylogenetic tree was constructed. Differently, from the topology of the phylogenetic tree we found that SARS-CoV is more close to group 1 within genus coronavirus. To date, genomes from 12 SARS-CoV isolates and 12 previously identified coronaviruses have been completely sequenced. The unrooted phylogenetic tree was constructed for genomes from 12 SARS-CoV isolates and that from 12 previously identified coronviruses (Fig. 1) .
