Association constant of the sex-specific agglutinin in the yeast, Hansenula wingei.
Association constants were determined for absorption of the sex-specific agglutinin from mating type 5 of Hansenula wingei by cells of type 21, the opposite mating type. Absorption was determined by following the radiolabeled sulfur in purified agglutinin extracted from cells grown in 35S-labeled medium. Association was proved to be reversible under conditions where cell agglutination was In se...

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...
متن کاملMating 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...
متن کاملRare-Cell Fusion Events between Diploid and Haploid Strains of the Sexually Agglutinative Yeast HANSENULA WINGEI.
Diploids of the yeast Hansenula wingei are nonagglutinative and do not form zygotes in mixed cultures with either sexually agglutinative haploid mating type. However, a low frequency of diploid x haploid cell fusions (about 10(-3)) is detectable by prototrophic selection. This frequency of rare diploid x haploid matings is not increased after the diploid culture is induced for sexual agglutinat...
متن کاملPhysiology 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...
