“…The initial genome naming and annotation of PRV proposed that L1, L2, L3, M1, M2, M3, S1, S2, S3 and S4 segments code for the λ1, λ2, λ3, μ2, μ1, μNS, σ3/p13, σ2, σNS and σ1 proteins, respectively (Palacios et al., 2010). This scheme was followed by Kibenge et al (2013) when establishing the first PRV genome in GenBank (GCA_002829625.1) and has been followed by a number of subsequent researchers (Di Cicco et al., 2017; Kibenge et al., 2019; Polinski, Marty, Snyman, & Garver, 2019; Takano et al., 2016). However, one early study reversed the naming of L1 and L3 so that the term L1 would be used to identify the segment that codes λ3, similar to the terminology applied to an analog, mammalian orthoreovirus (MRV) (Markussen et al., 2013).…”
