Table 1.

Sequencing data collected for transcriptomic sampling points, including the total number of raw reads, the total number of trimmed reads, the percentage of trimmed reads that mapped to either the a genome or a gene model belonging to P. tricornutum or A. macleodii, and the percentage of the total mapped reads that corresponded to the A. macleodii and P. tricornutum genomes.
