Analysis of the possible homologous recombination in the alignment sequences of SARS-CoV-2 and Rattus coronaviruses containing spike, E, and N genes. A plot display graphically illustrating recombination event at 3863–4254 position in alignment sequences (Pink region). Yellow line: KF294371- KM349742. Purple line: KM349742-MT049951. Green line: KF294371-MT049951. A schematic structure of the SARS-CoV-2 genome has been exhibited in the above plot. B Phylogenetic tree based on the ignore of recombination events, and C Phylogenetic tree based on the recombination event, (square) putative recombinant, (circle) potential minor parent, (triangle) potential major parent. The phylogenetic trees were constructed by the neighbor-joining (NJ) method with the bootstrap value (1000 replicates)
