In contrast, the four SpDCoV strains share a significantly lower identity to sparrow CoV HKU17 (58.2-58.6%) than to three PDCoV strains (82.7-87.7%) in their S protein (Fig. 1b and Supplementary Table S2 ). In addition, they share a relatively lower identity (90.7-91.5% and 93.5-95.5%) to sparrow CoV HKU17 than the PDCoV strains (94.9-95.8% and 96.1-98.1%) in their E and M proteins, respectively (Supplementary Table S2 ). These findings were also confirmed by phylogenetic tree analysis of amino-acid sequences in which the four SpDCoV strains clustered together and were closely related to PDCoV and sparrow CoV HKU17 strains in ORF1ab, E, M, and N trees ( Fig. 1c and Supplementary Figure S1 ).	./cache/cord-315355-a25ba7dz.txt	./txt/cord-315355-a25ba7dz.txt
