loss of viability upon nutrient depletion loss of viability upon nitrogen starvation loss of viability in stationary phase upon nitrogen depletion A cell population phenotype in which a smaller than normal proportion of cells in the population remains viable when cells in a culture in stationary phase are deprived of nitrogen. FYPO:0001178 loss of viability upon nitrogen deprivation midori loss of viability upon nitrogen depletion loss of cell population viability upon nitrogen starvation decreased viability upon nitrogen starvation 2012-06-27T14:04:23Z Use this term to annotate experiments in which a culture is grown under nitrogen-depleted conditions, and then the number of cells viable enough to form a colony upon return to conditions supporting vegetative growth is measured and compared to wild type. Also consider 'sensitive to nitrogen starvation' (FYPO:0002124). reduced viability upon nitrogen starvation
