Title: Molecular Identification and Complete Nucleotide Sequence of a Tomato Yellow Leaf Curl Virus Isolated from Vigna sinensis
Abstract: In the fall of 2008,the cowpea growing in a greenhouse in Shanghai suburban suffered a disease characterized by chlorotic and yellowing leaves.The complete nucleotide sequence of a tomato yellow leaf curl virus was amplified from DNA extracted from diseased plants.The sequence comparisons and phylogenetic analysis revealed that the pathogen was Tomato yellow leaf curl virus-Israel(TYLCV-IL),a member of the genus Begomovirus.The genome consisted of circular ssDNA with 2781 nucleotides,which has the typical characteristic of Old World monopartite begomoviruses with six ORFs corresponding to V2 and V1(Capsid Protein gene)on the viral strand,and C3,C2,C1 and C4 on the complementary strand.This is the first report that a natural Tomato yellow leaf curl virus infected V.sinensis.
