Maize stripe virus RNA5 is of negative polarity and encodes a highly basic protein

Relationship Between Maize Stripe Virus and Rice Stripe Virus

Maize stripe virus (MStpV) and rice stripe virus (RSV) were compared serologically, chemically and physically. Cross-reactions in agar gel double-diffusion and microprecipitin tests, and neutralization of MStpV infectivity by antiserum to either virus showed that MStpV and RSV are serologically related. Both viruses sedimented slowly and in a heterodisperse manner in rate-zonal sucrose gradient...

The Barley Stripe Mosaic Virus yb Gene Encodes a Multifunctional Cysteine-Rich Protein That Affects Pathogenesis

Barley stripe mosaic virus contains seven genes, one of which specifies a 17-kD cysteine-rich protein, yb, that is known to affect virulence. To further characterize the role of yb in pathogenesis, we mutagenized sequences encoding amino acids within two clusters of cysteine and histidine residues in the cysteine-rich domain and a group of basic amino acids located between the clusters and dete...

Nonchromosomal stripe of maize.

Segment 5 of the rice dwarf virus genome encodes a protein highly conserved within the phytoreoviruses.

The complete nucleotide sequence of segment 5 (S5) of the rice dwarf virus (RDV) genome was determined. RDV S5 is 2571 bp in length and has a single long open reading frame which encodes a polypeptide of 801 amino acids (Mr 90495). When compared to the wound tumor virus genome S5, there was 56.9% and 52.8% similarity in the nucleotide and amino acid sequences, respectively. This high similarity...

A highly attenuated measles virus vaccine strain encodes a fully functional C protein.

The P, V, and C proteins of measles virus are encoded in overlapping reading frames of the P gene, which makes it difficult to analyze the functions of the individual proteins in the context of virus infection. We established a system to analyze the C protein independently from the P and V proteins by placing its gene in an additional transcription unit between the H and L genes. Analyses with ...
