Two begomoviruses (Java virus-1 and Java virus-2), two satellite DNAs (DNAβ01 and DNAβ02), and a recombinant DNA (recDNA) were cloned from a single tomato plant from Indonesia with leaf curl symptoms, and the role of these satellite DNAs in the etiology of begomovirus disease was investigated. The genome organizations of the two viruses were similar to those of other Old World monopartite begomoviruses. Comparison of the sequences with other begomoviruses revealed that Java virus-1 was a newly described virus for which the name Tomato leaf curl Java virus (ToLCJAV) is proposed. Java virus-2 was a strain of Ageratum yellow vein virus (AYVV) (AYVV-[Java]). ToLCJAV or AYVV-[Java] alone did not induce leaf curl symptoms in tomato plants. However, in the presence of DNAβ02, both ToLCJAV and AYVV-[Java] induced leaf curl symptoms in tomato plants. In the presence of DNAβ01, these viruses induced mild leaf curl symptoms in tomato plants. The recDNA had a chimeric sequence, which arose from recombination among ToLCJAV, AYVV-[Java], DNAβ01, and DNAβ02; it was replicated only in the presence of AYVV-[Java] in tomato plants.
