Kyoto team develops way to detect "invisible" plankton death from viral infection

A new digital-PCR method shows phytoplankton can be actively lysed by viruses well before their populations visibly decline.

What to know

  • A new digital PCR method quantifies plankton cell lysis via cell-free rRNA, revealing mortality invisible to standard population monitoring.
  • Viral infection raised cell-free rRNA production about 46-fold, and active cell lysis about 302-fold, versus uninfected cultures.
  • Dissolved organic carbon release from lysis can peak while a plankton population is still growing, not just when it visibly declines, complicating existing biogeochemical models.
  • The team plans to extend the method to distinguish different species-level causes of plankton mortality.

    Eurasia Review republishes the full study writeup

    A fuller account of the Kyoto University findings, including methodology details and researcher quotes, circulated via Eurasia Review and social sharing.

    “We did not expect the temporal decoupling between population declines and cell lysis.”

    Kyoto University team quantifies "invisible" plankton cell death

    Researchers developed a digital PCR-based method measuring cell-free rRNA to detect viral-induced cell lysis in diatoms and raphidophytes, finding lysis boosted rRNA release up to ~302-fold and that dissolved organic matter release can occur during population growth rather than only during visible decline.
