Diaphoretickes
Sign in to saveDiaphoretickes () is a major evolutionary lineage, or clade, of eukaryotic organisms spanning over 600,000 species. They comprise an enormous diversity of life forms, from single-celled protozoa to multicellular plants and numerous types of algae. The clade was discovered through phylogenetic analyses in the 21st century that revealed a close relationship between the supergroups Archaeplastida (or plants in a broad sense), Haptista, Cryptista, and SAR (Stramenopiles, Alveolata and Rhizaria).

Diaphoretickes () is a major evolutionary lineage, or clade, of eukaryotic organisms spanning over 600,000 species. They comprise an enormous diversity of life forms, from single-celled protozoa to multicellular plants and numerous types of algae. The clade was discovered through phylogenetic analyses in the 21st century that revealed a close relationship between the supergroups Archaeplastida (or plants in a broad sense), Haptista, Cryptista, and SAR (Stramenopiles, Alveolata and Rhizaria).
Before molecular analyses recovered this clade, evolutionary biologist Thomas Cavalier-Smith had already hypothesized an evolutionary proximity between plants and the remaining groups (collectively known as 'chromalveolates' in his classification system). He coined the term photokaryotes for these organisms, as they include almost all of the photosynthetic eukaryotes. He later called them corticates due to the presence of cortical alveoli in many of their members.
