Calcofluor-white Calcofluor-white Calcofluor-white is a special fluorescent stain that binds strongly to structures containing cellulose and chitin. In plant cell biology research, it is used for the staining of cell walls of both algae and higher plants. It is also useful in medicine and animal biology for the identification of fungi in the tissue, (it binds to the chitin in the cell walls of the fungi). In research, calcofluor-white is also used to stain bud scars of yeast cells because the bud scars have a higher content of chitin, which stains them more than the rest of the cell membrane. Due
Sexual selection in fungi by producing pheromones. In the isogamous budding yeast, Saccharomyces cerevisiae, pheromones are used to distinguish between different mating types and show a preference for higher concentrations of pheromones along with a rejection of lower concentrations. However, all of the pheromone studies within fungi have been performed in a laboratory. In order to further support this hypothesis, more research is necessary on the effects of natural gamete density, motility, and pheromone production in nature., Mushroom-forming fungi within Basidiomycetes produce sexually by the reciprocal migration of nuclei and have a male-biased OSR which aids in supporting that sexual selection is present within
