Sporulation in the budding yeast Saccharomyces cerevisiae.
In response to nitrogen starvation in the presence of a poor carbon source, diploid cells of the yeast Saccharomyces cerevisiae undergo meiosis and package the haploid nuclei produced in meiosis into spores. The formation of spores requires an unusual cell division event in which daughter cells are formed within the cytoplasm of the mother cell. This process involves the de novo generation of t...
متن کاملCell cycle dependency of sporulation in Saccharomyces cerevisiae.
The study of sporulation in Saccharomyces cerevisiae is complicated by the fact that not all cells in the population complete sporulation and that the kinetics of development of those which do are not synchronous. By separating vegetative cells by zonal rotor centrifugation into fractions of increasing cell volume and hence progressive stages of the vegetative cell cycle, it was possible to obs...
متن کاملRegulation of sporulation in the yeast Saccharomyces cerevisiae.
Sporulation of the budding yeast Saccharomyces cerevisiae — equivalent to gametogenesis in higher organisms, is a complex differentiation program induced by starvation of cells for nitrogen and carbon. Such environmental conditions activate coordinated, sequential changes in gene expression leading to production of haploid, stress-resistant spores. Sporulation comprises two rounds of meiosis co...
متن کاملRegulation of cell size in the yeast Saccharomyces cerevisiae.
For cells of the yeast Saccharomyces cerevisiae, the size at initiation of budding is proportional to growth rate for rates from 0.33 to 0.23 h-1. At growth rates lower than 0.23 h-1, cells displayed a minimum cell size at bud initiation independent of growth rate. Regardless of growth rate, cells displayed an increase in volume each time budding was initiated. When abnormally small cells, prod...
متن کاملCharacterization of Encapsulated Berberine in Yeast Cells of Saccharomyces cerevisiae
Berberine was loaded in yeast cells of Saccharomyces cerevisiaeas a novel pharmaceutical carrier to improve the treatment ofmany diseases. The yeast-encapsulated active materialsshowedhigh stability and bioavailability due to the enhanced solubility and sustained releasing. In this study, different characteristics of prepared berberine loaded yeast cells (loading capacity, release kinetic order...
