title: Detection and Identification of Dasheen mosaic virus Infecting Colocasia esculenta in India.
abstract: Reverse transcription polymerase chain reaction of the infected leaf samples of Colocasia esculenta plants showing severe whitish feathery symptoms were carried out using Potyvirus group specific primers, resulting in an amplicon of 327 bp, encoding the core region of the coat protein gene. Sequencing and BLAST analysis showed that the virus is distinct, closely related to Dasheen mosaic virus (DsMV). Sequence analysis revealed 86 and 96% identity at the nucleotide and amino acid level respectively with the DsMV isolate SY1(accession Number AJ628756). This is the first molecular level characterisation of the DsMV infecting C. esculenta in India.
