cord-252910-7qvnj6c8	Li, Xin	The discovery of a recombinant SARS2-like CoV strain provides insights into SARS and COVID-19 pandemics	2020-09-21		.txt	text/plain	4180	223	54	In the present study, we identified key recombination regions and mutation sites cross the SARS-CoV-2, SARS-CoV and SARS-like CoV clusters of betacoronavirus subgroup B. Different from these studies, we previously reported several other findings on SARS-CoV-2 for the first time, including the following in particular: (1) the alternative translation of Nankai coding sequence (CDS) that characterize the rapid mutation rate of betacoronavirus at the nucleotide level [2] ; (2) a furin cleavage site (FCS) "RRAR" in the junction region between S1 and S2 subunits (junction FCS) of SARS-CoV-2 that may increase the efficiency of viral entry into cells [3] ; and (3) the use of 5' untranslated-region (UTR) barcoding for the detection, identification, classification and phylogenetic analysis of-though not limited to-CoVs [4] . Using the insertions and deletions (InDels) at six sites, we identified two recently detected betacoronavirus strains RmYN01 and RmYN02 from a bat [6] and discovered that RmYN02 was a recombinant SARS2-like CoV strain.	./cache/cord-252910-7qvnj6c8.txt	./txt/cord-252910-7qvnj6c8.txt
