yeast sporulation

[georgeskohler]

Under starvation conditions (medium lacking nitrogen source) yeast will undergo meiosis to produce haploid spores. Why?

[CharonY]

What is the question directed at? The physiological role of sporulation or the regulatory cues derived from starvation?

[georgeskohler]

good point, I guess both why medium with limited nutrients which basically starves the yeast causes that from a mechanistic standpoint and the potential adaptive significance (maybe spores are hardy and can survive the lack of nutrients and then enter into normal growth phase when nutrients are available again...) I know yeast can exist and be propagated in haploid or diploid form in culture.
