Fig. 4.

Presence and distribution of AOFs in the γ- and δ-CoVs. Each column in the matrix represents a certain AOF. Red color (within the matrix cells) denotes the (TblastN) presence of AOFs that is also verified by a predicted ORF with length ≥30 aa, whereas if the length of the predicted ORF is <30 aa, then it is denoted with orange color. Inverted triangles denote AOFs that are present in both γ- and δ-CoV members. Downward arrows denote AOFs that have homologs in non-CoV genomes, together with their best PSI-BLAST hit e-value. Horizontal orange bars (above the matrices) denote the genomic region where the AOF is located, that is, M-N denotes the region between the Membrane and Nucleocapsid ORFs.
