Experimental evolution makes microbes more cooperative with their local host genotype.
Rebecca T. Batstone,Rebecca T. Batstone,Anna M O'Brien,Tia L. Harrison,Megan E. Frederickson,Megan E. Frederickson +5 more
TL;DR: Local and recent associations between bacterial strains and plant genotypes are due to selection for bacterial adaptation, and cooperation depends on the match between partner genotypes and increases as bacteria adapt to their local host.

A Deep Dive into the Complex Chemical Mixture and Toxicity of Tire Wear Particle Leachate in Fathead Minnow
Leah Chibwe,Joanne L. Parrott,Kallie Shires,Hufsa Khan,Stacey Clarence,Christine Lavalle,Cheryl Sullivan,Anna M O'Brien,Amila O. De Silva,Derek C. G. Muir,Chelsea M. Rochman +10 more
TL;DR: In this article, the effects of tire leachates on fathead minnow embryos were evaluated using high-resolution liquid chromatography Orbitrap mass spectrometers. And the effect of the presence and absence of small tire particulates in the leachate was investigated.

Mutualistic Outcomes Across Plant Populations, Microbes, and Environments in the Duckweed Lemna minor
TL;DR: It is suggested that duckweed source population, associated microbiome, and contaminant environment should all be considered for duckweed applications, such as phytoremediation, and duckweed microbes offer a robust experimental system for study of host–microbiota interactions under a range of environmental stresses.
Whose trait is it anyways? Coevolution of joint phenotypes and genetic architecture in mutualisms.
TL;DR: In this paper, the authors develop a simulation model of a host-microbe mutualism to explore the evolution of a multi-genomic trait, and show that genome-wide association studies can map joint traits to loci in multiple genomes and describe how fitness conflict and fitness feedback generate different multigenomic architectures with distinct signals around segregating loci.

Microbial effects on plant phenology and fitness
TL;DR: A review of current mechanistic and theoretical knowledge surrounding microbe-driven changes in plant phenology can be found in this article, where the authors highlight biases, gaps in knowledge, and future directions.
