Plants HC SAR megagroup

The Plants+HC+SAR megagroup is a group of eukaryotes proposed by Burki et al. (2008).

It includes:

This description includes all Bikonts that are not excavates. It is also referred to as Diaphoretickes or the SAR/HA Supergroup. It is not to be confused with Corticata, which was part of a different classification scheme that excluded Rhizaria from the SAR supergroup.

It was previously described as the sum of Archaeplastida, Rhizaria, and chromalveolates. However, this description is obsolete, largely due to the discovery that chromalveolata was not monophyletic.

It includes most of the species engaging in photosynthesis, except for the Euglenozoa and Cyanobacteria.
