Although the spring semester has officially begun, it does not feel like spring here in Madison. Despite earlier concerns, the weather has cooled down enough for our lakes to freeze. Here in the McMahon Lab, we’ve had a productive winter break! We published two new papers over the break:
- Oyserman, Ben O., Daniel R. Noguera, Tijana Glavina del Rio, Susannah G. Tringe, and Katherine D. McMahon. “Metatranscriptomic insights on gene expression and regulatory controls in Candidatus Accumulibacter phosphatis.” The ISME Journal (2015). In this paper, lab member Ben Oyserman investigates differences in gene expression under aerobic and anaerobic conditions in Candidatus Accumulibacter phosphatis, a key player in wastewater treatment systems. Ben identifies some new metabolic strategies for efficient electron use in A. phosphatis, as well as some potential regulatory mechanisms for gene expression.
- Bendall, Matthew L., Sarah LR Stevens, Leong-Keat Chan, Stephanie Malfatti, Patrick Schwientek, Julien Tremblay, Wendy Schackwitz et al. “Genome-wide selective sweeps and gene-specific sweeps in natural bacterial populations.” The ISME Journal (2016). Here, lab member Sarah Stevens uses a metagenomic time series to look out how diversity within a bacterial population changes over time. Sarah observes changes in diversity at both the gene and genome levels, suggesting that there are multiple ways that bacterial populations evolve in natural environments.
