The complete nucleotide sequence and genomic organization of Citrus Leprosis associated Virus, Cytoplasmatic type (CiLV-C)

The Citrus leprosis disease (CiL) is associated to a virus (CiLV) transmitted by Brevipalpus spp. mites (Acari: Tenuipalpidae). CiL is endemic in Brazil and its recently spreading to Central America represents a threat to citrus industry in the USA. Electron microscopy images show two forms of CiLV:...

Description
Summary:	The Citrus leprosis disease (CiL) is associated to a virus (CiLV) transmitted by Brevipalpus spp. mites (Acari: Tenuipalpidae). CiL is endemic in Brazil and its recently spreading to Central America represents a threat to citrus industry in the USA. Electron microscopy images show two forms of CiLV: a rare nuclear form, characterized by rod-shaped naked particle (CiLV-N) and a common cytoplasmic form (CiLV-C) associated with bacilliform-enveloped particle and cytoplasmic viroplasm. Due to this morphological feature, CiLV-C has been treated as Rhabdovirus-like. In this paper we present the complete nucleotide sequence and genomic organization of CiLV-C. It is a bipartite virus with sequence similarity to ssRNA positive plant virus. RNA1 encodes a putative replicase polyprotein and an ORF with no known function. RNA2 encodes 4 ORFs. pl5, p24 and p61 have no significant similarity to any known proteins and p32 encodes a protein with similarity to a viral movement protein. The CiLV-C sequences are associated with typical symptoms of CiL by RT-PCR. Phylogenetic analysis suggests that CiLV-C is probably a member of a new family of plant virus evolutionarily related to Tobamovirus.
