Abstract:

Nucleotide sequence data from DNA-dependent RNA polymerase (rpoC) genes were used to examine the phylogenetic relationships among the phycobiliprotein- and three known chlorophyll b-containing (prochlorophyte) cyanobacteria. The phylogenetic trees obtained confirm the polyphyletic nature of the prochlorophytes. Data from Prochloron cells obtained form six different tunicate host species suggest that at least two closely related groups of Prochloron exist in the same area in Palau, West Caroline Islands. Overall, however, the genetic diversity within the analyzed samples was much smaller than within the nonsymbiotic Prochlorococcus.
