Hunt, D. E. (Charles V. Chapin Hospital, Providence, R.I.) and P. L. Carpenter. Sterols as components in the mating reaction of Hansenula wingei. J. Bacteriol. 86:845-847. 1963.-Agglutinative mating strains 5 and 21 of the yeast Hansenula wingei did not agglutinate after the cells of these two strains were treated with nystatin. The agglutination-inhibiting action of this antibiotic could not b...

Mating reaction in the yeast Hansenula wingei; preliminary observations and quantitation.

Wickerham (1956) has described a new species, Hansenula wingei, which exhibits a rather unusual mating reaction. When vegetative haploid cells of the two mating types are mixed, a strong agglutination reaction may occur. On agar, the cells set to a solid mass which resists further mixing and adheres tenaciously to the instrument used for mixing the cells. When the mass of cells is placed in wat...

Physiology of the conjugation process in the yeast Hansenula wingei.

The yeast Hansenula wingei is a favourable organism for study of the physiology of the conjugation process (cell fusion). Microscopic observations on fusion are presented which reveal that the mating cells in contact fuse by a softening of the cell wall, followed by formation of a conjugation tube, dissolution of the cross-walls between them, and formation of a new bud a t the point of juncture...

Protein as a specific cell surface component in the mating reaction of Hansenula wingei.

a hydrophobic cell mass. This phenomenon has been developed into a quantitative assay for agglutinability which has made it possible to study the mechanism of this attraction (Brock, J. Bacteriol., 75, 697, 1958). Work to be published elsewhere has shown that the two mating types do not differ in electrostatic charge or degree of hydration. Rather, the agglutination seems to be related to the p...
