Abstract
SOME YEASTS PRODUCE SEXUAL SPORES (ascospores) in a variety of shapes and surface ornamentations. These intriguing structures have hitherto been used only in yeast classification. Here, we propose the likely primary function of spore shape and ornamentations, in water-driven movement, as aiding the dispersal of the spores from enclosed containers (asci). This interpretation of the mechanics involved might find application in nano-, aeroand hydro-technologies with the re-scaling of these structures.
Highlights
Through sexual reproduction,[1] some yeasts produce microscopic containers that enclose mainly water and spores of many different shapes and various nano-scale surface ornamentations.[2]
Using radiolabelled thin-layer chromatography, [1H]2D-COSY NMR, gas chromatography–mass spectrometry as well as infrared spectroscopy, we revealed that the polyunsaturated 3-hydroxy oxylipin, 3R-hydroxy-5Z,8Z,11Z,14Z-eicosatetraenoic acid (3R-HETE or 3-OH 20:4), was aUNESCO-MIRCEN, Department of Microbial, Biochemical and Food Biotechnology, bCentre for Confocal & Electron Microscopy, cDepartment of Mathematics and Applied Mathematics, University of the Free State, P.O
Message in a bottle We found a message concerning this question when studying spore release from bottle-shaped containers in the yeast Dipodascopsis uninucleata.[3,5,7]
