Bacteria
Intracellular

Portiera has bacterial homologues of fungal carotenoid biosynthesis genes, supporting the hypothesis that endosymbiotic bacteria can provide a source of carotenoids and indicating that related lineages of sap-feeding insects have acquired the ability to synthesize carotenoids by independent mechanisms (chemical biosynthesis/pigmentation alteration).
