Discovery of a rich gene pool of bat SARS-related coronaviruses provides new insights into the origin of SARS coronavirus

Phylogenetic trees based on nucleotide sequences of ORF1a (A) and ORF1b (B). The trees were constructed by the maximum likelihood method using the LG model with bootstrap values determined by 1000 replicates. Only bootstraps > 50% are shown. The scale bars represent 0.03 (A) and 0.02 (B) substitutions per nucleotide position. Rs, Rhinolophus sinicus; Rf, Rhinolophus ferremequinum; Rm, Rhinolophus macrotis; Ra, Rhinolophus affinis; Rp, Rhinolophus pusillus; As, Aselliscus stoliczkanus; Cp, Chaerephon plicata. SARSr-CoVs detected in bats from the single cave surveyed in this study are in bold. Sequences detected in southwestern China are indicated in red.
