Since their discovery, single-domain antigen-binding fragments of camelid-derived heavy-chain-only antibodies, also known as nanobodies (Nbs), have proven to be of outstanding interest as therapeutics against human diseases and pathogens including viruses, but their use against phytopathogens remains limited. Many plant viruses including Grapevine fanleaf virus (GFLV), a nematode-transmitted ic...
Grapevine degeneration in grapevines caused by Grapevine fanleaf virus (GFLV) has been documented in many viticultural regions worldwide (Andret-Link et al. 2004). It is one of the major economically important virus diseases affecting the longevity of grapevines and reducing the fruit yield and fruit quality. Infected grapevines show a range of foliar symptoms consisting of leaf deformation, ye...
The full-length transcript of grapevine fanleaf virus (GFLV) RNA2 produces a primary product of 122K when translated in the rabbit reticulocyte system. This 122K polyprotein is completely processed in vitro by the RNA1-encoded 24K proteinase. The positions of the cleavage sites within the polyprotein have been mapped and the genome organization of GFLV-F13 RNA2 has been established. The order o...
Mekuria, T. A., Gutha, L. R., Martin, R. R., and Naidu, R. A. 2009. Genome diversity and intraand interspecies recombination events in Grapevine fanleaf virus. Phytopathology 99:1394-1402. Grapevine fanleaf virus (GFLV) was documented in self-rooted vines of four grapevine (Vitis vinifera) cultivars in eastern Washington. GFLV was found as mixed infection in cvs. Pinot Noir, Chardonnay, and Cab...
The nucleotide sequence of a satellite RNA (satRNA) associated with a lilac isolate of arabis mosaic virus (ArMV) was determined from cDNA copies. The sequence was 1104 nucleotides in length excluding the poly(A) tail, contained a long open reading frame which encodes a polypeptide of 360 amino acids, with an Mr of 39K. Nucleotide sequence comparisons revealed that the ArMV-associated satRNA sh...
An antiserum was raised against a fusion protein containing the C-terminal half of the protein (P3) encoded by the satellite RNA of grapevine fanleaf virus (GFLV; F13 isolate) and the N-terminal portion of the CI repressor of phage lambda. This antiserum specifically recognized P3 synthesized in the in vitro wheatgerm translation system and also in infected Chenopodium quinoa plants. In these p...
Somatic embryos were successfully regenerated from callus tissue of anthers and ovaries excised from inflorescences of grapevines infected with grapevine fanleaf virus (GFLV). Production of pro-embryogenic masses (PEMS) was controlled by specific growth regulators and culture conditions, including heat incubation at 35°C. Somatic embryos (containing roots and cotyledons) and plantlets were subj...
