Differential effects of growth temperature on ice nuclei active at different temperatures that are produced by cells of Pseudomonas syringae.

Summary

Because other studies have indicated that ice nuclei active at the lowest assay temperatures may reflect the amount of ice nucleation protein produced, while higher nucleation temperatures reflect aggregates of this ice nucleation protein, data was normalized to the frequency of ice nuclei active at the lowest ice nucleation temperatures (which also correspond to the most abundant nuclei). Then the number of ice nuclei in cells grown at 9, 15 and 20 deg C that were active at different assay temperatures was very similar. Differences in ice nucleation frequency that occurred over all assay temperatures in cells grown between 9 and 20 deg C may be attributed to differences in the total number of nuclei present in the population of cells.
