Tomato Satellite DNA of Tomato leaf curl virus-Indonesia (ToLCV sat-DNA) was detected from natural infected tomato plants. ToLCV sat-DNA was approximately half-length of genomic DNA of ToLCV (1347 b). ToLCV sat-DNA was low sequence identity to the genomic DNA (41%). ToLCV sat-DNA contained 5 ORFs (V1-5) in virion-sense and 4 ORFs (C1-4) in complementary-sense each capable of encoding proteins with a molecular weight greater than 4 kDa. In intergenic region, a 34-base potential stem-loop forming region was found. It included the conserved nonanucleotide sequence TAATATTAC. The repetitive sequence GCTACGCA and GCTACGCC were found in intergenic region. The sequence of ToLCV sat-DNA contained an A-rich region between nucleotides 708 and 1002 (60% A). ToLCV sat-DNA had 80% and 63% nucleotide sequence identity to AYVD DNAβ Singapore and CLCuD DNAβ, respectively.
