Bipolar budding

This type of asexual reproduction is characteristic of the genus Schizosaccharomyces, where formation of the daughter cell occurs without the constriction seen in the above-described types. In this case, formation of a cross-wall occurs between mother and daughter, followed by separation.

Evidence for the presence of endo-/ -( 1 - 3)-glucanases in budding yeasts also has been forthcoming in recent years. In the bipolarly budding yeasts of the genus Hanseniaspora Abd-El-Al and Phaff (39) demonstrated in cell extracts and in the culture fluid an endo-/3-( 1 3)-...

Budding Asexual reproduction of yeasts involving the formation of daughter cells (buds) off of the mother cell. Yeasts can reproduce by bipolar (buds only appear at end of cell) or multipolar/mulilaterial (buds can appear on all surfaces of cell).
