Elevated CO2 and phosphate limitation favor Micromonas pusilla through stimulated growth and reduced viral impact.
Growth and viral infection of the marine picoeukaryote Micromonas pusilla was studied under a future-ocean scenario of elevated partial CO2 (pCO2; 750 μatm versus the present-day 370 μatm) and simultaneous limitation of phosphorus (P). Independent of the pCO2 level, the ratios of M. pusilla cellular carbon (C) to nitrogen (N), C:P and N:P, increased with increasing P stress. Furthermore, in the...
متن کاملPhytoplankton Virus Production Negatively Affected by Iron Limitation
Fe-limited monocultures of the ubiquitous algae Micromonas pusilla and Phaeocystis globosa were infected with their respective viruses (MpV and PgV) to ascertain the effect of Fe-limitation on phytoplankton host-virus dynamics. The effect of the viral shunt on Fe concentrations and bioavailability is starting to gain attention, since not only is Fe released through lysis, but also its solubilit...
متن کاملFlow cytometric analysis of phytoplankton viability following viral infection
Two flow cytometric assays using physiological probes were used on the phytoplankton species Phaeocystis pouchetii and Micromonas pusilla to examine the assays’ utility in detecting viral infections. Dead cells were detected using the membrane impermeant nucleic-acid dye SYTOXGreen, which stains algal cells that have lost their membrane integrity. Live cells were detected using the membrane per...
متن کاملResource dynamics during infection of Micromonas pusilla by virus MpV-Sp1.
Viruses infecting marine phytoplankton drive phytoplankton diversity, terminate blooms and shuttle genetic material. Assessments of the scale of viral impacts on trophic networks are, however, speculative. We investigated fluxes of DNA between host and virus during infection of the prasinophyte alga Micromonas pusilla by phycodnavirus MpV SP1. Under a light-dark regimen, viral genomes accumulat...
متن کاملDevelopment and application of an algorithm for detecting Phaeocystis globosa blooms in the Case 2 Southern North Sea waters
While mapping algal blooms from space is now well-established, mapping undesirable algal blooms in eutrophicated coastal waters raises further challenge in detecting individual phytoplankton species. In this paper, an algorithm is developed and tested for detecting Phaeocystis globosa blooms in the Southern North Sea. For this purpose, we first measured the light absorption properties of two ph...
