What is Presence Of Phycoerythrin In Two Strains Of Prochlorococcus (cyanobacteria) Isolated From The Subtropical North Pacific Ocean about?
__Prochlorococcus__ is a ubiquitous marine oxyphotobacterium characterized by the presence of DV‐chl __a__ and __b__. In addition, the type strain __Prochlorococcus marinus__ Chisholm et al. CCMP 1375 (or SS120), an isolate from the Sargasso Sea, contains low levels of an unusual phycoerythrin. Until now, it has been unclear if phycoerythrin occurs randomly within this systematic group and if the molecular characteristics of this phycoerythrin are restricted to this single strain. Here, we show that two additional __Prochlorococcus__ strains from the Pacific Ocean also contain similar low levels of phycoerythrin. DNA sequence and phylogenetic analyses demonstrated that this phycoerythrin is very similar to the phycoerythrin of __P. marinus__ SS120 and differs from the classic cyanobacterial phycoerythrins. In contrast, a third isolate from the Arabian Sea lacks phycoerythrin. Based on the DV‐chl __b:a__ ratio and 16S rRNA sequence data, we classify the two Pacific phycoerythrin‐containing isolates as low‐light‐adapted strains and the Arabian Sea isolate as a high‐light‐adapted strain. Thus, we provide further evidence to link the physiology of an individual genotype and the presenc
