georgeskohler Posted November 15, 2009 Share Posted November 15, 2009 Under starvation conditions (medium lacking nitrogen source) yeast will undergo meiosis to produce haploid spores. Why? Link to comment Share on other sites More sharing options...
CharonY Posted November 16, 2009 Share Posted November 16, 2009 What is the question directed at? The physiological role of sporulation or the regulatory cues derived from starvation? Link to comment Share on other sites More sharing options...
georgeskohler Posted November 17, 2009 Author Share Posted November 17, 2009 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. Link to comment Share on other sites More sharing options...
