The Archaeplastida+HC+SAR megagroup is a group of eukaryotes proposed by Burki et al. (2008).[1] It is also referred to as Diaphoretickes (/ˌdaɪəfəˈrɛtɪkiːz/) or the SAR/HA Supergroup, or the Corticata with Rhizaria.[2]
It includes:
- Archaeplastida (comprising the plants, red algae, green algae, and glaucophytes)
- Hacrobia (the "HC" refers to Haptista and Cryptista, the two basal clades in the group)
- SAR supergroup (consisting of stramenopiles+alveolates+Rhizaria)
According to this description, it includes most of the species engaging in photosynthesis, except for the Euglenozoa and Cyanobacteria. It includes all Bikonts that are not excavates and Hemimastigophora.
The name "Corticata" comes from Cavalier-Smith's hypothesis about the common origin of the cortical alveoli of glaucophytes and alveolates.[3]
The megagroup was previously described as the sum of Archaeplastida, Rhizaria, and chromalveolates.[4] However, this description is obsolete, largely due to the discovery that chromalveolata is not monophyletic.
