Family: Actinidiaceae Edible fruit
Actinidia chlorotic ringspot-associated emaravirus (AcCRaV)
Taxonomic position
Genus: Emaravirus Family: Fimoviridae
Geographical distribution
AcCRaV infection in plants of Actinidia chinensis was reported from China (Zheng et al. 2017).
Symptoms and host(s)
The virus-infected kiwifruit plants exhibit chlorotic spots, chlorotic ring-spots, and vein-yellowing symptoms on leaves.
Transmission
The virus is transmitted by an eriophyid mite vector. The virus is also mechanically sap-transmissible to Nicotiana benthamiana on which chlorotic and ring-spots develop.
Virion properties and genome
The virions are spherical, enveloped by a double membrane, and measure from 80 to 100 nm in diameter. The genome consists of a multipartite negative-sense, single-stranded RNA genome with five genomic components: RNA1 7061 nt (KT861481), RNA2 2267 nt (KT861482), RNA3 6078 nt (KT861483), RNA4 1664 nt (KT861484), and RNA5 1474 nt (KT861485) (Zheng et al. 2017; Elbeaino...
