sensitive to osmotic stress midori hypersensitive to osmotic stress A cell phenotype observed in the vegetative growth phase of the life cycle in which cells show increased sensitivity to osmotic stress. sensitive to osmotic stress during vegetative growth 2011-04-19T04:37:01Z Use this term if you have assayed growth of cells exposed to osmotic stress in culture. If you have assayed the response to osmotic stress at the subcellular or molecular level, consider annotating to 'abnormal cellular response to osmotic stress' (FYPO:0000193). sensitive to osmotic stress during mitotic cell cycle osmotic stress resistance: decreased FYPO:0000270 sensitive to stress during vegetative growth
