Meiosis in Hansenula holstii and H. wingei.
Diploid isolates of Hansenula holstii Wick. and H. wingei Wick. usually produce two or three ascospores per ascus. An unusual nuclear event during meiosis might account for less than the expected number of four. When acridine orange or Feulgen staining was used, meiosis in both species followed the pattern established in higher plants and animals. Deoxyribonuclease treatment destroyed nuclear s...
متن کاملBiochemical and cellular changes occuring during conjugation in Hansenula wingei.
Brock, Thomas D. (Indiana University, Bloomington). Biochemical and cellular changes occurring during conjugation in Hansenula wingei. J. Bacteriol. 90:1019-1025. 1954.-A technique has been devised for deagglutinating mixed populations of conjugating cells so as to be able to visualize microscopically early stages of the conjugation process. A cell can form a conjugation tube only when in conta...
متن کاملAmino Acids as Protective Compounds in Ultraviolet-irradiated Hansenula Wingei.
Hunt, D. E. (Charles V. Chapin Hospital, Providence, R.I.). Amino acids as protective compounds in ultraviolet-irradiated Hansenula wingei. J. Bacteriol. 88:893-895. 1964.-"Prefeeding" Hansenula wingei with small concentrations of either tryptophan, cystine, tyrosine, phenylalanine, leucine, cysteine, threonine, isoleucine, ethionine, norvaline, or histidine protected this yeast against inactiv...
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...
متن کاملSterols as Components in the Mating Reaction of Hansenula Wingei.
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...
