Apple stem grooving virus (ASGV, genus Capillovirus) is disseminated worldwide, usually causing a latent infection in most commercial apple cultivars. However, infected scions grafted onto sensitive material display reduction of yield, loss of fruit quality and tree decline. In Brazil ASGV is associated with severe phloem necrosis, xylem pitting and decline of apple trees on Maruba-kaido (Malus prunifolia cv. Ringo) rootstocks usually in a complex with other latent viruses. Two Brazilian ASGV isolates from a mixed infection causing differing reactions on apple cv. Fuji on Maruba-kaido rootstocks, i.e., normal growth vs. tree decline, have been completely sequenced. The differing intensity of symptoms they co-induced on several woody indicator... |

A new sobemovirus, which we have named "mimosa mosaic virus" (MimMV), was found by high-throughput sequencing and isolated from a mimosa (Mimosa sensitiva L.) plant. The genome sequence was confirmed by Sanger sequencing and comprises 4595 nucleotides. Phylogenetic analysis based on the predicted amino acid (aa) sequences of the P2b protein (encoded by ORF2b) and the coat protein showed 52.7% and 31.8% aa sequence identity, respectively, to those of blueberry shoestring virus. The complete genome sequence of MimMV was less than 47% identical to those of other sobemoviruses. These data suggest that MimMV is a member of a new species in the genus Sobemovirus, for which the binomial name ?Sobemovirus mimosae? is proposed. |

Grapevines can host up to 86 virus species, some of which affect plant vigor, production and fruit quality (Fuchs, 2020). In 2014, a Vitis vinifera cv. Semillon vine showing yellow speckles and mild leafroll symptoms in Bento Gonçalves, RS, Brazil, was investigated for viruses (Silva et al., 2017), resulting in the detection of grapevine enamovirus 1, grapevine yellow speckle viroid 1 and hop stunt viroid. |
