AbstractA novel dsRNA virus named “Thelonectria quadrivirus 1” (TQV1) was found in a member of the genus Thelonectria (Ascomycota), isolated from a root associated with stem collar necrosis of Fraxinus excelsior L. The complete genome of TQV1 is composed of four segments, each containing a single ORF on the positive sense RNA. The sequence of the 5´ (5´-(C/T)ACGAAAAA-3´) and 3´termini (5´AT(T/G)AGCAATG(T/C)GC(G/A)CG-3’) of dsRNA 1 (4876 bp), dsRNA 2 (4312 bp), dsRNA 3 (4158 bp), and dsRNA 4 (3933 bp) are conserved. Based on its genome organization and phylogenetic position, TQV1 is suggested to be a new member of the family Quadriviridae. This is the first report of a mycovirus infecting a member of the genus Thelonectria.

ABSTRACT We describe here a double-stranded RNA mycovirus, termed Fusarium graminearum alternavirus 1 (FgAV1/AH11), from the isolate AH11 of the phytopathogenic fungus F. graminearum . Phylogenetic analysis showed that FgAV1/AH11 belongs to a newly proposed family, Alternaviridae . This is the first report of a mycovirus in the family Alternaviridae that infects F. graminearum .

ABSTRACT We describe a novel positive single-stranded RNA virus, termed Fusarium langsethiae hypovirus 1 (FlHV1), from the isolate AH32 of the phytopathogenic fungus Fusarium langsethiae. The properties of FlHV1 permit assignment to the genus Alphahypovirus in the family Hypoviridae. This is the first report of a mycovirus identified in F. langsethiae.

We report here the complete genome sequence of a novel reovirus, designated Chiqui virus (CHQV) strain CoB38d, that was isolated from a pool of unidentified mosquitoes collected in northern Colombia in 2013. CHQV has nine double-stranded DNA (dsRNA) genome segments and has similarity to viruses belonging to the family Reoviridae, subfamily Spinareovirinae.

To date, only 13 genomes of green sulfur bacteria (family Chlorobiaceae ) have been sequenced. The sequenced strains do not cover the full phylogenetic diversity of the family. We determined the complete genome sequence of Prosthecochloris sp. strain CIB 2401, thereby increasing the genome information for the poorly represented marine Chlorobiaceae .
