Abstract: Abutilon mosaic virus (AbMV - genus Begomovirus, family Geminiviridae) represents historically one of the first viruses studied by plant virologists. It is transmitted in a persistent manner by Bemisia tabaci. The present study concerns the molecular characterisation of the AV1 gene, coding the coat protein, of an AbMV strain (named AbMV-PG) identified on symptomatic plants of Abutilon sellovianum var. marmorata, growing in some nurseries of Apulia (southern Italy). The whole amino acid sequence and the nucleotide sequence corresponding to the core region of 575 nt of the AV1 gene of AbMV-PG, have been used for phylogenetic analysis with those comparable sequences from other Begomovirus available to EMBL and SWISSPROT. The phylogenetic analysis showed that the Apulian isolate belongs to the western isolate of Begomovirus and is more related to the English and to the Indian strains of AbMV than to the Hawaiian strain. Moreover, amino acid changes in the coat protein, involved in the lost of vector transmissibility of the AbMV Indian strain, were identified in the CP sequence of AbMV-PG. For this reason, transmissibility of AbMV-PG by Bemisia tabaci is considered improbable.
