    A novel oxylipin-associated ‘ghosting’ phenomenon in yeast flocculation (2000)

    Notizen: Abstract Research on the distribution of oxylipins (3-hydroxy fatty acids) in flocculant strains of the yeast Saccharomyces cerevisiae led to the uncovering of a novel ‘ghosting’ phenomenon observed during assumed lectin-mediated aggregation. We found that intracellular oxylipin-containing osmiophilic layers migrate through yeast cell walls in a ‘ghostlike’ fashion without visually affecting the cell wall structure or the layers. This migration resulted in the binding of these layers to cell walls of adjacent cells. Consequently, ‘ghosting’ seems a prerequisite for flocculation to occur. However, ‘ghosting’ alone may not be sufficient to ensure flocculation.

    Mapping the distribution of 3-hydroxylipins in the Mucorales using immunofluorescence microscopy (2000)
    Springer
    Antonie van Leeuwenhoek 78 (2000), S. 39-42 
    Details
    ISSN: 1572-9699
    Schlagwort(e): 3-hydroxylipins ; immunofluorescence microscopy ; Mucorales
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract The distribution of endogenous 3-hydroxylipins (3-OH oxylipins) in representatives of the Mucorales was mapped using immunofluorescence microscopy. Strains of each of the following genera were examined: Absidia, Actinomucor, Cunninghamella, Mortierella (subgenus Micromucor), Mortierella (subgenus Mortierella), Mucor and Rhizomucor. Immunofluorescence microscopy was carried out using an antibody that was raised against 3R-hydroxy-5Z,8Z,11Z,14Z-eicosatetraenoic acid (3R-HETE), which cross-reacts with other 3-OH oxylipins. Subsequently, the occurrence and distribution of the antibody on the various reproductive stages of each fungus was noted. In Absidia, Actinomucor, Mortierella (subgenus Micromucor), Mucor and Rhizomucor, 3-OH oxylipins were found to be associated with the columellae and/or wall of the sporangium. In the representative of Cunninghamella, the 3-OH oxylipins were associated with the single-spored sporangiola. No 3-OH oxylipins were detected in the strains representing Mortierella (subgenus Mortierella).

    Ascospore aggregation and oxylipin distribution in the yeast Dipodascopsis tothii (2000)
    Springer
    Antonie van Leeuwenhoek 77 (2000), S. 389-392 
    Details
    ISSN: 1572-9699
    Schlagwort(e): ascospore ultrastructure ; assembly ; Dipodascopsis tothii ; oxylipins
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract Upon cultivation of the yeast Dipodascopsis tothii in its sexual stage, small ascospores are released individually from the ascus tip, which then assemble in sheathed cluster balls. In contrast to Dipodascopsis uninucleata, this yeast produced smooth bean shaped ascospores with sheath-like appendages that assemble in a disordered sheathed ball of ascospores outside the ascus. Strikingly, upon release, the ascus tip contained 3-hydroxy oxylipins, while the released ascospore clusters contained little or no 3-hydroxy oxylipins as indicated by immunofluorescence microscopy. In D. uninucleata, these oxylipins are concentrated on the spore surface and interspore matrix, but not on the ascus tip.
