Fig 9. Diversity of centromere features within the Stramenopila-Alveolata-Rhizaria (SAR) supergroup.

Fig 9

Simplified schematics (not to scale) showing the structures, epigenetic modifications, sizes and compositions of reported centromeres across the SAR lineages. Asterisk, epigenetic state was not examined in the diatom centromeric regions; however, several AT-rich DNA sequences can be employed for episome maintenance, suggesting diatom centromere might not be epigenetically dependent. The histone modification H3K27me3 was only tested in P. sojae. Phylogenetic tree was constructed using TimeTree [88]. Homo sapiens, Arabidopsis thaliana and Neurospora crassa were used as representatives of animals, plants and fungi for the phylogenetic analysis, and are used as outgroups illustrating the evolutionary status of the SAR supergroup.
