has_part decreased vegetative cell population growth progressively decreasing vegetative cell population growth rate progressively decreasing vegetative cell population growth rate followed by return to normal growth rate progressively decreasing cell population proliferation followed by return to normal proliferation progressively decreasing cell population growth rate followed by return to normal growth rate during vegetative growth A cell population phenotype in which vegetative cell population growth is slower than normal for several generations, with the population growth rate decreasing over successive generations, after which the population resumes growing at a normal or near-normal rate. progressively reduced vegetative cell population growth rate followed by return to normal growth rate FYPO:0005394 2016-05-03T14:48:15Z This population growth pattern is often seen with mutations that affect telomere maintenance. The slowing growth reflects a high rate of cell death as telomeres shorten, and in a small sub-population of cells, chromosomes circularize allowing the population to resume growth at a higher, often normal, rate. midori progressively decreasing cell proliferation followed by return to normal proliferation progressively reduced cell proliferation followed by return to normal proliferation emergence of telomerase-deficient survivors
