Nucleotide sequence of a chickpea chlorotic stunt virus relative that infects pea and faba bean in China

We determined the genome sequence of a new polerovirus that infects field pea and faba bean in China. Its entire nucleotide sequence (6021 nt) was most closely related (83.3% identity) to that of an Ethiopian isolate of chickpea chlorotic stunt virus (CpCSV-Eth). With the exception of the coat protein (encoded by ORF3), amino acid sequence identities of all gene products of this virus to those of CpCSV-Eth and other poleroviruses were <90%. This suggests that it is a new member of the genus Polerovirus, and the name pea mild chlorosis virus is proposed.
