Free Living N Fixation review!

Darian Smercina, PhD student in the Tiemann lab, recently published an exciting review titled To Fix or Not To Fix: Controls on Free-Living Nitrogen Fixation in the Rhizosphere. Published in Applied and Environmental Microbiology, the paper explores Free Living Nitrogen Fixation (FLNF) as a form of biological N fixation distinct from symbiotic N fixation that may be harnessed to reduce fertilizer inputs in cropping systems. Specifically, the review outlines the ways that environmental conditions and resource availability may control FLNF for a diverse range of rhizosphere diazotroph taxa and offers methodological recommendations to address knowledge gaps in future FLNF studies.

Fall 2018 All Hands Meeting

On November 14th and 15th, MMPRNT members convened for our bi-annual all hands meeting. Highlights of the meeting included a mini poster session, project update presentations from group members and a talk by guest speaker Sasha Kravchenko. We also held group-wide discussions where we outlined upcoming publications and identified assay-specific data validation protocols. Overall, the meeting provided a great forum for PIs, graduate students, post-docs and technicians to contextualize their individual work within the broader objectives of the MMPRNT project. Cheers to another successful all hands meeting everyone!
