A begomovirus was isolated from a Pyrenacantha sp. plant with yellow mosaic symptoms collected in a maize production field in Mozambique. The complete DNA-A and DNA-B components have a genomic organization typical of Old World, bipartite begomoviruses. Based on the current ICTV species demarcation criteria for the genus Begomovirus, the virus isolate, named Pyrenacantha yellow mosaic virus (PyYMV), is a member of a new species, for which the name "Begomovirus pyrenacanthae" is proposed. Alignment of their common regions (CR) indicated a 35-nt insertion in the DNA-A CR. The nt sequence identity between the CRs is only 83% but increases to 96% when the 35-nt insertion is removed from the alignment. This is the first report of a begomovirus naturally infecting Pyrenacantha spp. © 2021. The Author(s), under exclusive licence to Springer-Verlag GmbH Austria, part of Springer Nature.
