A mycovirus (named FusoV) from the phytopathogenic fungus, Fusarium solani f. sp. robiniae SUF704, has two kinds of double-stranded (ds) RNA genomes, designated M1 and M2. The cDNAs were constructed from FusoV genomic dsRNAs. The sequences of M1 and M2 cDNAs comprised 1645 and 1445bp, respectively. Sequence analysis showed that each dsRNA had a single long open reading frame (ORF) on only one of the strands. M1 ORF encodes a 519-amino acid residue polypeptide with a predicted molecular mass of 60 kDa. RNA-dependent RNA polymerase-conserved motifs were identified in the predicted amino acid sequence, and the polymerase synthesized dsRNA in vitro. The M2 ORF encodes a polypeptide of 413 amino acid residues with a predicted molecular mass of 44 kDa. The predicted amino acid sequence contained the sequence corresponding to those found in the purified 44-kDa capsid protein of FusoV.

D008969 Molecular Sequence Data Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories. Sequence Data, Molecular,Molecular Sequencing Data,Data, Molecular Sequence,Data, Molecular Sequencing,Sequencing Data, Molecular
D008970 Molecular Weight The sum of the weight of all the atoms in a molecule. Molecular Weights,Weight, Molecular,Weights, Molecular
D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
