Phylogenetic dendrograms based upon an alignment of selected complete sequences (or DNA A components) of begomoviruses. The begomovirus (or DNA A component) sequences used for the alignment are Bean golden yellow mosaic virus (BGYMV), Cabbage leaf curl Jamaica virus (CabLCuJV), Chili leaf curl virus (ChLCV), Cowpea golden mosaic virus (CPGMV), Cotton leaf curl Kokhran virus (CLCuKV), Cotton leaf curl Multan virus (CLCuMV), Cucurbit leaf crumple virus (CuLCrV), Indian cassava mosaic virus (ICMV), Malvastrum leaf curl virus (MaLCV), Mungbean yellow mosaic India virus (MYMIV), Okra yellow crinkle virus (OYCrV), Papaya leaf curl China virus (PaLCuCNV), Pepper leaf curl Bangladesh virus (PepLCBDV), Pepper yellow leaf curl Indonesia virus (PepLCIV), Pepper leaf curl Lahore virus (PepLCLV), Radish leaf curl virus (RaLCV), Tobacco curly shoot virus (TbCSV) and Tomato golden mosaic virus (TGMV). The tree was arbitrarily rooted on the sequence of the DNA B component of Tomato leaf curl New Delhi virus (ToLCNDV). The database accession number in each case is given. Isolate and strain descriptors are as given in Fauquet et al. [23].
