Marine Microbe Contains Multitudes

Boeuf and colleagues collected samples of SAR324 microbial communities from this research vessel, the Kilo Moana. (School of Ocean And Earth Science And Technology at University of Hawaii at Manoa)A deep dive into microbial genomics reveals one bacterial species is made of four ecologically distinct groups with different lifestyles.

When “The Blob” Made It Hotter Under the Water

This data image shows the monthly average sea surface temperature for May 2015. Between 2013 and 2016, a large mass of unusually warm ocean water--nicknamed the blob--dominated the North Pacific, indicated here by red, pink, and yellow colors signifying temperatures as much as three degrees Celsius (five degrees Fahrenheit) higher than average. Data are from the NASA Multi-scale Ultra-high Resolution Sea Surface Temperature (MUR SST) Analysis product. (Courtesy NASA Physical Oceanography Distributed Active Archive Center)With genomic samples collected before, during and after The Blob, researchers developed a preliminary model of how marine microbial communities are affected by warming events.

The Case for Conservation

Female (left) and male (right) Ceratodon purpureus plants. Females typically grow larger than males in several traits, like the length of leaves. Males often turn red when developing antheridiophores, which in mosses are the structures that produce sperm (seen in the bottom right. (Sarah Carey)High-quality reference genome sequences of the male and female fire moss plants are now available, and lessons from their sex chromosomes could help improve crop yields. [Read More]

Plotting a Model for Virus-Host Warfare Deep Below Ground

Image of biofilm with both Altiarchaea (blue) and viruses (red). (Victoria Turzynksi and Lea Griesdorn)Researchers describe how viruses repeatedly attempt to infect and destroy their hosts – and how the microbes resist. [Read More]

A Natural Mechanism Can Turbocharge Viral Evolution

Virus tail fibers – signified in the cartoon by the blue virus’ downward pointing ‘arms’— don't allow the virus to attach to a purple tinted cell type.A genetic element that enables rapid, targeted mutation is surprisingly widespread and appears to allow viruses to hunt new microbial prey.

Bacteria and Fungi Divvy Up the Work in Forest Floor

The study site in the coniferous forest located in the Bohemian Forest National Park, Czech Republic. (Petr Baldrian)While thousands of species of fungi and bacteria dwell on — and within — the forest floor, who’s recycling the plant biomass? [Read More]

Gut Fungi: Unexpected Source of Novel Chemicals

The anaerobic fungus Anaeroromyces robustus growing on reed canary grass. (Vaithiyalingam Shutthanandan, PNNL/EMSL)Combing through the genomes of four anaerobic fungal species has revealed, for the first time, that this group is unexpectedly powerful: they can whip up dozens of complex natural products, including new ones.

An Automated Tool for Assessing Virus Data Quality

Artistic interpretation of CheckV assessing virus genome sequences from environmental samples. (Rendered by Zosia Rostomian​, Berkeley Lab)The CheckV tool helps researchers to assess the completeness of virus genome sequences and complements a community effort to develop guidelines and best practices for defining virus data quality.

A One-Stop Shop for Analyzing Algal Genomes

Unicellular algae in the Chlorella genus, magnified 1300x. (Andrei Savitsky)By bringing together publicly available algal genomes into one place, PhycoCosm allows users to easily compile data that answers what genes are present in which organisms, when are they expressed, and what they do.
