Cordgrass keeps Georgia's marshes healthy, but how does it stay healthy? @KostkaLab used advanced genomic methods to discover bacteria detoxify sulfide and fix nitrogen, enhancing plant health and resilience. 🌾b.gatech.edu/4aDzHH5

The mechanisms underlying plant-microbe interactions in coastal ecosystems are little explored. Rolando et al. use multi-omics & biogeochemical measurements to investigate saltmarsh cordgrass root microbiome. @joseluisrolando @KostkaLab nature.com/articles/s41467-0…

Excited to finally see this online! Here, we link N fixation to sulfur oxidation in Spartina alterniflora roots -the dominant marsh plant in the US. Interestingly, our discovered symbionts are closely related to those living in the gills of marine clams! nature.com/articles/s41467-0…

A good week so far! On Monday I defended my PhD Thesis. Today, the second first-author publication from my PhD work was just released 🙂

So proud of @autpeterson for representing @GTSciences and @GaTechMicrobes at the ABRCMS conference! To any prospective grad students reading this, I’m happy to tell you more about opportunities at both @QBioS_GT and in Biology. Just ping me here or via email.

Last week, I attended the 2022 Annual Biomedical Research Conference for Minoritized Students. There, I represented the School of Biological Sciences and @GTMicrobes at Georgia Tech as an exhibitor to promote our programs to prospective graduate students. #ABRCMS2022

From northern Minnesota to coastal Georgia, wetlands are essential. Building on work w/@ORNL, Joel Kostka's team @GeorgiaTech is studying microbes' roles in salt marshes to understand how climate change will affect soils & plants that store carbon: cos.gatech.edu/news/joel-kos…

Little is known of how plant/microbe interactions regulate coastal ecosystems. @KostkaLab of @GeorgiaTech looks at the carbon/nitrogen exchange that govern interactions in Spartina alterniflora — a dominant plant along the Gulf of Mexico and Atlantic Coast. #2023FICUS (7/13)

We just released this preprint exploring the trajectory of salt marsh dieback events in South Carolina and Louisiana, USA. We found that extreme climatic events, which are increasing in frequency and intensity due to climate change, triggered dieback events
