FIG. 1.

Time course of cell numbers (solid circles) and growth rate (open circles) of the Skeletonema costatum culture used for the construction of the subtracted cDNA libraries. Arrows indicate the time points in the RG and death stages at which samples were collected for total RNA extraction. Error bars indicate standard errors (SE) of the mean cell number (n = 3). Data points without an error bar indicate that the error bar was smaller than the symbol. Growth rates were calculated from the mean cell number and plotted without error bars.
