RT Journal Article T1 Geminivirus-Encoded Proteins: Not All Positional Homologs Are Made Equal T2 Geminiviruses: Positional vs. Functional Homology A1 Pérez-Luna, Ana Isabel A1 Lozano-Durán, Rosa K1 Virus fitopatógenos AB Geminiviruses are insect-transmitted plant viruses with circular, single-stranded (ss)DNA genomesthat cause devastating diseases in major crops worldwide. The family Geminiviridae comprisesmore than 450 species divided in nine genera, based on genome organization, host range, andinsect vector: Begomovirus, Mastrevirus, Curtovirus, Becurtovirus, Topocuvirus, Turncurtovirus,Capulavirus, Gablovirus, and Eragrovirus (Zerbini et al., 2017). The most diverse genus in thisfamily is Begomovirus, which to date includes 409 different species (reviewed in Zhao et al.,2019). Begomoviruses can be further subdivided in monopartite, with one-molecule genomes,and bipartite, with two-molecule genomes (Figure 1A). Regardless of whether they are mono- orbi-partite, the size of each genomic DNA molecule is ∼3 kb.Apart from the obvious economic and practical interest PB Frontiers YR 2020 FD 2020-05-05 LK https://hdl.handle.net/10630/34089 UL https://hdl.handle.net/10630/34089 LA eng NO Luna AP and Lozano-Durán R (2020) Geminivirus-Encoded Proteins: Not All Positional Homologs Are Made Equal.
