Genome Sequence of Grapevine Virus T, a Novel Foveavirus Infecting Grapevine
Here, we report the genome sequence of grapevine virus T (GVT), a novel single-stranded RNA virus identified from a transcriptome of grapevine. The genome of GVT is 8,701 nucleotides in length and encodes five open reading frames. GVT is a putative member of the genus Foveavirus in the family Betaflexiviridae.

متن کاملGenetic characterization of grapevine-infecting Botrytis cinerea isolates from Argentina.
BACKGROUND Botrytis cinerea is an ascomycete with a high genetic diversity and complex population structure, as reported from several hosts and sites. However, nothing is known about its genetic diversity in Argentina. AIMS The aim of this work is to estimate the genetic diversity of a local population of B. cinerea isolates obtained from grapevine in Argentina. METHODS In this work, 35 str...
متن کاملOpines in naturally infected grapevine crown gall tumors
Crown gall tumors collected from naturally infected plants of 7 grapevine varieties were analysed for the presence of opines. Eighty-five of the tested 90 samples contained known Agrobacterium vitis-induced opines. Octopine was the most common, it was found in 50 samples. Twentyeight crown galls contained nopaline and 8 were vitopine positive. There was only one tumor that contained two opines,...
متن کاملA new group of hepadnaviruses naturally infecting orangutans (Pongo pygmaeus).
A high prevalence (42.6%) of hepatitis B virus (HBV) infection was suspected in 195 formerly captive orangutans due to a large number of serum samples which cross-reacted with human HBV antigens. It was assumed that such viral infections were contracted from humans during captivity. However, two wild orangutans were identified which were HBV surface antigen positive, indicating that HBV or rela...
