• Publication: Presence of Prochlorococcus in the aphotic waters of the western Pacific Ocean

  Prochlorococcus, the smallest but most abundant marine primary producer, plays an important role in carbon cycling of the global ocean. As a phototroph, Prochlorococcus is thought to be confined to the euphotic zone, with commonly observed maximum depths of ∼150–200 m. But here we show, using flow cytometry and cellular ribosomal content, for the first…

• Publication: In situ activity of a dominant Prochlorococcus ecotype (eHL-II) from rRNA content and cell size

  In the open ocean genetically diverse clades of the unicellular cyanobacteria Prochlorococcus are biogeographically structured along environmental gradients, yet little is known about their in situ activity.  To address this gap, here we use the numerically dominant Prochlorococcus clade eHL-II (eMIT9312) as a model organism to develop and apply a method to examine their in…

• Publication: Carbon allocation under light and nitrogen resource gradients in two model marine phytoplankton

  Marine phytoplankton have conserved elemental stoichiometry, but there can be significant deviations from this Redfield ratio.  Moreover, phytoplankton allocate reduced carbon to different biochemical pools based on nutritional status and light availability, adding complexity to this relationship. This allocation influences physiology, ecology and biogeochemistry.  Here we present results on the physiological and biochemical properties of…
