title: Complete nucleotide sequence and the genome organization of tobacco leaf curl geminivirus from Japan.
abstract: The genomic DNA of tobacco leaf curl geminivirus (TLCV) from tomato plants with leaf curl disease in Japan has been sequenced. The single circular DNA molecule comprises 2,761 nucleotides. TLCV DNA contains six open reading frames (ORFs) capable of encoding proteins with a molecular weight greater than 10 K. In total nucleotide sequence comparisons with other geminiviruses, TLCV was most closely related to tomato leaf curl virus from Taiwan (TwToLCV) (76% identity), tomato leaf curl virus from Bangalore (ToLCV-Ba) (74%) and agerantum yellow vein virus (AYVV) (74%), all possessing a monopartite genome. The significant but relatively low sequence similarity in the genomic DNA between TLCV and other geminiviruses suggests it is a distinct geminivirus in genus Begomovirus.
