acaryochloris marina acaryochloris marina acaryochloris marina is a symbiotic species of the phylum cyanobacteria that produces chlorophyll d, allowing it to use far-red light, at 770 nm wavelength. acaryochloris marina scientific classification domain: bacteria phylum: cyanobacteria class: cyanophyceae order: synechococcales family: acaryochloridaceaekomárek et al. 2014 genus: acaryochlorismiyashita & chihara 2003 species: a. marina binomial name acaryochloris marinamiyashita & chihara, 2003 chlorophyll d description it was first discovered in 1993 from coastal isolates of coral in the republic of palau in the west pacific ocean and announced in 1996. despite the claim in the 1996 nature paper that its formal description was to be published shortly thereafter, a tentative partial description was presented in 2003 due to phylogenetic issues (deep branching cyanobacterium). genome its genome was sequenced in 2008, revealing a large bacterial genome of 8.3 mb with nine plasmids. etymology the name acaryochloris is a combination of the greek prefix a (ἄν) meaning "without", caryo (κάρυον) meaning "nut" (here intended as "nucleus") and chloros (χλωρός) meaning green; therefore it is neo-latin acaryochloris meaning "without nucleus green". the specific epithet marina is latin meaning "marine". classification
