Genetic diversity in Prochlorococcus populations flow cytometrically sorted from the Sargasso Sea and Gulf Stream

摘要

An investigation into the genetic structure of Prochlorococcus picophytoplankton in depth profiles from the Sargasso Sea and the Gulf Stream revealed a high degree of genetic heterogeneity within local populations. Partial Sequencing of cloned polymerase chain reaction products amplified from flow cytometrically sorted cells was used To identify 6-21 different Prochlorococcus petB/D alleles recovered from each of eight sorted samples, with 68 Alleles identified among 187 clones in the combined data set.
