Editing Prochlorococcus (section)

==Pigments==
''Prochlorococcus'' is closely related to ''[[Synechococcus]],'' another abundant photosynthetic cyanobacteria, which contains the light-harvesting antennae [[Phycobilisome|phycobilisomes]]. However, ''Prochlorochoccus'' has evolved to use a unique light-harvesting complex, consisting predominantly of divinyl derivatives of [[chlorophyll a]] (Chl a2) and [[chlorophyll b]] (Chl b2) and lacking monovinyl chlorophylls and phycobilisomes.<ref>{{cite journal |vauthors=Ting CS, Rocap G, King J, Chisholm S |year=2002 |title=Cyanobacterial photosynthesis in the oceans: the origins and significance of divergent light-harvesting strategies |journal=[[Trends in Microbiology]] |volume=10 |issue=3 |pages=134–142 |doi=10.1016/s0966-842x(02)02319-3|pmid=11864823 }}</ref> ''Prochlorococcus'' is the only known wild-type oxygenic phototroph that does not contain Chl a as a major photosynthetic pigment, and is the only known prokaryote with α-carotene.<ref>{{cite journal |vauthors=Goericke R, Repeta D|year=1992 |title=The pigments of ''Prochlorococcus marinus'': the presence of divinyl chlorophyll a and b in a marine prokaryote |journal=[[Limnology and Oceanography]] |volume=37 |issue=2 |pages=425–433 |doi=10.4319/lo.1992.37.2.0425|bibcode=1992LimOc..37..425R |doi-access=free }}</ref>
