Table 3. Gene expression analysis for the combined treatment with both Alexandrium fundyense strains.

Genotype	24 vs 48 h	24 vs 72 h	24  vs 96 h	Common upregulated at all time points
Alex2	604	959	5724	244
Alex5	496	1177	909	61

The table displays the numbers of upregulated genes for comparisons at various time points after exposure for each A. fundyense strain to the cage containing interacting P. kofoidii cells and conspecific A. fundyense. The last column shows the number of genes that were upregulated at all points.
