Viral interactions with their hosts are complex and can be beneficial, yet the public perception of #viruses is generally negative. New experimental designs are required to characterize the full spectrum of viral interactions. #microbiology

Mycorrhizae and Land Plants – An Update

by Roberto
I am fortunate that among the first impressions of my day, I take in this view of land plants. Given my proclivity for microbiology my mind inevitably wonders to what I cannot see, the underground network of filamentous fungi connecting the roots of those plants, the mycorrhizae.

Happy to see the first experimental project I led finally out in the world! With Jeremy Moore, Sydney Olsen, and Mike Travisano

We combined experimental evolution and mathematical modeling to ask: do bacteria evolve to swim away from phages?

This week, 24 new Winogradsky columns came into being, with help from the KS2 classes at my local school 🦠💚

As they all needed egg yolks, back at home I'm now making meringues! Lots and lots of meringues!!!

I have no idea how the students mud jars will end up, but here's a pic of one of my winter experiments a couple of years ago with soil/water from the same river...

Alternative stable states, nonlinear behavior, and predictability of microbiome dynamics

"the abrupt community changes observed through the time-series could be described as shifts between “alternative stable states“ or dynamics around complex attractors."

Fascinating study!

The methanogen core and pangenome: conservation and variability across biology’s growth temperature extremes

"Increased methanogenic growth temperature is associated with reduced genome size, and thermotolerant organisms...have larger core genome fractions, suggesting that genome size is governed by temperature rather than phylogeny. "

Fascinating study on #genome #evolution :

Scaling of Protein Function Across the Tree of Life

"The abundance of functional categories in a given genome scales with genome size, suggesting that universal constraints shape category abundance. Here we look across the tree of life to understand how genome evolution may be related to functional scaling. "

High-resolution metagenomic reconstruction of the freshwater spring bloom https://doi.org/10.1186/s40168-022-01451-4 #microbiology #bioinformatics


Blooms of #Cyanobacteria pose a significant threat to #freshwater systems including rivers driving both #eutrophication and its dire implications for freshwater species as oxygen availability plummets and also the additional threat posed by #cyanotoxins produced by some Cyanobacteria.

This new research in Scientific Reports takes a #metagenomics and Q-PCR approach to explore the composition of the Cyanobacterial populations and their cyanotoxin production gene in major rivers across the United States (in 2019) and identifies Microcystis as the key toxin producing genus across this study.

We are all too familiar with the all-too-often catastrophic impacts of #COVID19 #infection on human #health.

This fascinating new #metagenomics research in mBio explores a potentially important and intriguing link between the presence and relative abundance of different functional guilds present in the human gut #microbiome (including short chain fatty acid biosynthesis and virulence functions) and disease severity and outcomes resulting from the virus. Clearly a subject for future extended studies to explore potential increases in severity due to infection and exacerbated or mitigated by differences in gut microbiomes.

As we (humans) get to grips with how to scale up #hydrogen as an energy source (and for energy storage) and as part replacement for #fossilfuels, this new research (once again) shows that #microbes have beaten us to it and evolved their own solutions for energy - in this case using hydrogen power.

This new research in Nature Microbiology explores how hydrogen in seawater supports growth of multiple and diverse #bacterial species.

Fof those (like me) in #Melbourne , you may be interested that the research also includes study of this process within #PortPhillipBay sediments.

I started a new jar, in parallel with the old jar. The only difference is that the new one uses distilled water instead of tap water, and about half as much yeast extract. I inoculated the new jar with about 8oz from the old one. #ScienceExperiment #microbiology


#Virus control

This exciting new research explores the influence of #virus #infection in changing the balance of organic matter degradation between #bacteria and #eukaryotes in #marine #carboncycling during #phytoplankton blooms.

Based on #mesocosm studies, this research demonstrates how #viruses infecting different #microorganisms change community dynamics and the release and potential fate of marine carbon from primary production.

When I started my lab a few years ago I started building up an in-house library for students. Two of the first books I bought are The Logic of Chance (Eugene Koonin) and The Origins of Genome Architecture (Michael Lynch). Both are remarkable books that discuss genomics in the context of microbial diversity and the tree of life.

What other genomics/evolution classics do people always keep around?
