Nitrogen depletion induces the formation of resting spores in the diatom Chaetoceros socialis. Light micrograph of a colony of vegetative cells (a) and a colony in which vegetative cells turned into resting spores (b); scale bars = 10 µm. Time course concentration of vegetative cells and spores (cells, spores mL−1; left axis) and percentage of spores (right axis) in cultures grown in nitrogen-replete control (c) and in nitrogen-deplete treatment (d); data are shown as average ± S.D. (n = 3). Samples for the differential gene expression analysis were collected on day 2 in the control and on days 2 (T2), 3 (T3) and 4 (T4) for the treatment and are marked with dashed green circles in panels c and d, respectively
