M. Pospisek et al., ISOLATION AND CHARACTERIZATION OF THE DSRNA VIRUS FROM THE YEAST ENDOMYCES-MAGNUSII, FEMS microbiology letters, 116(2), 1994, pp. 231-236
Virus-like particles (VLPs) have been isolated from the yeast Endomyce
s magnusii. The VLPs measure 43 nm in diameter and contain six species
of dsRNA (0.78, 0.83, 1.77, 1.84, 2.64, 4.30 kb respectively). E. mag
nusii produces a 'toxic' protein, which reduces the growth, and change
s the colony morphology, of sensitive strains of Hansenula sp. growing
on solid media. All strains of E. magnusii tested produced the 'toxin
' and contained the VLPs. Current procedures of curing failed to destr
oy the ability to produce the 'toxin'.
