Resurrecting microbiomes past

Rothfels Lab graduate student Mick Song has caught the microbiome bug! After finishing a project studying the variation in the microbiota of Daphnia magna across genotypes, populations, and temperatures with longtime collaborator Dr. Sarah Schaack at Reed College, he gave a guest lecture and tutorial on microbiomes in Dr. Jeremy Coate‘s Bioinformatics course last November.

Now he is teaming up with Dr. Jordan Metzgar curator of the Massey Herbarium at Virginia Tech (who taught Carl how to do PCR many years ago!) and undergraduate student Amber Reaney to explore the possibility of capturing microbial diversity in herbarium specimens of Azolla, building off of the recent work of Daru and colleagues [1]. While they break new ground in the herbarium, Mick will be in the lab with live Azolla trying out some exciting protocols for extracting and characterizing the microbial diversity in the leaf pockets of Azolla across the genus. Although the Azolla-Nostoc symbiosis has been well-described [2], the community composition of the bactobionts as a whole remains poorly understood. Who knows what they will find!
