Isolation and characterization of a potyvirus associated with bushy dwarf symptom in chickpea, Cicer arietinum, in India uri icon

abstract

  • A potyvirus that induced stunting and a characteristic bushy appearance at the apical region, due to proliferation of terminal branches with narrowed, reduced and deformed leaflets, was isolated from chickpea in India. The virus was sap-transmissible to 14 species of Chenopodiaceae, Leguminosae, Solanaceae and Malvaceae; Chenopodium amaranticolor was a good local lesion host. Virus particles, trapped by immunosorbent EM and stained with uranyl acetate, were 710±10 nm long. Purified virus preparations contained a single polypeptide species of 32?500 Da and one nucleic acid species of 3.1×106 Da. The virus was serologically related to soybean mosaic, azuki bean mosaic and peanut mottle potyviruses but not to clover yellow vein, pea seed-borne mosaic and bean yellow mosaic potyviruses. On the basis of these properties, the virus was identified as a previously undescribed potyvirus in chickpea, for which the name chickpea bushy dwarf virus is proposed
