loss of viability upon nitrogen starvation loss of viability upon G0 to G1 transition A cell population phenotype in which a smaller than normal proportion of cells in the population remains viable upon exiting G0 phase. loss of mitotic competence upon recovery from cell quiescence loss of viability upon exit from cell quiescence loss of mitotic competence upon recovery from quiescence 2018-08-29T14:12:46Z FYPO:0006660 loss of viability upon exit from quiescence midori Also see the cell-level term 'inviable cell upon G0 to G1 transition' (FYPO:0000238). Use this term to annotate experiments in which a culture is grown under nitrogen-depleted conditions until cells have entered and remained for some time in G0, and then the number of cells that can exit G0 and form a colony upon return to conditions supporting vegetative growth is measured and compared to wild type. loss of mitotic competence upon recovery from G0
