Irreversible loss of haploid-specific genes in E. huxleyi CCMP1516. Ploidy-specific gene expression detected by microarray in haplodiplontic strain RCC1216/1217 (top bar) compared with genome content of diploid strain CCMP1516 (top three pie charts) as analyzed by (i) BLASTN against JGI draft CCMP1516 genome assembly (JGI, inner circle), (ii) comparative genome hybridization (CGH, middle circle) and (iii) BLASTN against Illumina contigs (Illumina, outer circle). Color code: red, genes absent from CCMP1516 based on all three analyses; pink, putative lower copy number in the CCMP1516 genome suggested by CGH. Insets beside top bar show micrographs of 1N cell (arrowheads indicate flagella) and calcified 2N cell at the same magnification (scale bar, 5 μm). Bottom two rows of pie charts: BLASTN analysis of 1N, 2N and nonspecific Sanger EST clusters from E. huxleyi strain RCC1216/1217 against Illumina contigs from strains 92A and Eh2. Clusters with no hits are in red.
