The apical growth of about 20% of young tomato plants in observed fields near Campinas, State of São Paulo, Brazil, had yellow streaking of veins. Leaf symptoms developed into patches of yellow mosaic and the leaves became wavy. The whitefly Bemisia tabaci Genn. transmitted a pathogen from the infected tomato plants to healthy tomato and potato plants, reproducing the original symptoms in tomato. The apical leaves of infected potatoes showed yellow or green mottle that developed into leaf distortion with yellow blotches, symptoms indistinguishable from potato-deforming mosaic disease (2). DNA was extracted from these tomato and potato plants (1). Using DNA from the infected tomato plant, polymerase chain reaction (PCR) with the degenerate primer pair PAC1v1978/ PAV1c715 (1), which amplifies part of the rep gene (AC1 ORF), the common region (CR), and part of the cp gene (AV1 ORF), and with the primer pair PBC1v2039/PBV1c800, which amplifies part of BC1 ORF, CR, and part of BV1 ORF, gave virus-specific DNA fragments of the sizes expected from a whitefly-transmitted geminivirus. These were cloned and the complete nucleotide (sequences for DNA-A (pToYA, GenBank accession no. U79998) and DNA-B (pToYB, GenBank accession no. U80042) fragments obtained. Nucleotide identity between the CRs (184 nucleotides) was 90%, strongly indicating that those fragments correspond to a bipartite subgroup III geminivirus. PCR with the DNA from infected potato gave the expected size fragment for DNA-A. The partial sequence of the rep gene was 100% identical to the homologous sequence from the PCR fragment from the infected tomato. A search in the GenBank, EMBL, DDBJ, and PDB databases, using the BLAST program, found no identical geminivirus. The highest identity for the CR was 75% to tomato mottle geminivirus-Florida (ToMoV) and 74% to bean golden mosaic virus-Brazil. For the rep gene, the highest identity was 73% to tomato yellow leaf curl virus-Israel, an Old World geminivi-rus, followed by 71% to tomato golden mosaic virus-Brazil (TGMV) and ToMoV. For the cp gene, the highest identity was 86% to TGMV, followed by 83% to squash leaf curl geminivirus. Therefore, we propose the name tomato yellow vein streak geminivirus (ToYVSV) for this distinct virus (2).
