Culturing the marine cyanobacterium Prochlorococcus
Prochlorococcus is the numerically dominant primary producer in open ocean ecosystems. Analysis of Prochlorococcus genome sequences from cultured isolates and ocean samples has broadened interest in studying this tiny cell, and efforts are underway to develop it into a model system for studying marine microbial ecology. A critical component of these efforts has been the development of systemati...
متن کاملGenomes of diverse isolates of the marine cyanobacterium Prochlorococcus
The marine cyanobacterium Prochlorococcus is the numerically dominant photosynthetic organism in the oligotrophic oceans, and a model system in marine microbial ecology. Here we report 27 new whole genome sequences (2 complete and closed; 25 of draft quality) of cultured isolates, representing five major phylogenetic clades of Prochlorococcus. The sequenced strains were isolated from diverse re...
متن کاملGenome reduction by deletion of paralogs in the marine cyanobacterium Prochlorococcus.
Several isolates of the marine cyanobacterial genus Prochlorococcus have smaller genome sizes than those of the closely related genus Synechococcus. In order to test whether loss of protein-coding genes has contributed to genome size reduction in Prochlorococcus, we reconstructed events of gene family evolution over a strongly supported phylogeny of 12 Prochlorococcus genomes and 9 Synechococcu...
متن کاملEffects of phosphorus starvation versus limitation on the marine cyanobacterium Prochlorococcus MED4 II: gene expression.
Phosphorus (P) availability drives niche differentiation in the most abundant phytoplankter in the oceans, the marine cyanobacterium Prochlorococcus. We compared the molecular response of Prochlorococcus strain MED4 to P starvation in batch culture to P-limited growth in chemostat culture. We also identified an outer membrane porin, PMM0709, which may allow transport of organic phosphorous comp...
متن کاملCryo-electron tomography reveals the comparative three-dimensional architecture of Prochlorococcus, a globally important marine cyanobacterium.
In an age of comparative microbial genomics, knowledge of the near-native architecture of microorganisms is essential for achieving an integrative understanding of physiology and function. We characterized and compared the three-dimensional architecture of the ecologically important cyanobacterium Prochlorococcus in a near-native state using cryo-electron tomography and found that closely relat...
