Wi. Golubev et T. Boekhout, SENSITIVITY TO KILLER TOXINS AS A TAXONOMIC TOOL AMONG HETEROBASIDIOMYCETOUS YEASTS, Studies in mycology, (38), 1995, pp. 47-58
Killer sensitivity patterns differ among phylogenetically diverse basi
diomycetous yeasts. Taxonomic and phylogenetic applications and limita
tions of this character are discussed. Yeast and hyphal phases of a si
ngle organism may differ in sensitivity to killer toxins. The two vari
eties of Cryptococcus neoformans can be differentiated using killer to
xins of Cryptococcus laurentii.
