Switching biofilm formation on and off in yeast
When a group of microorganisms needs to stick together, they build a biofilm. The cells cement themselves together onto a surface, forming durable structures that are notoriously hard to remove. In a medical setting, biofilms can contribute to dangerous antibiotic resistance. In the August issue of G3, Cromie et al. use a yeast model to…

Fast-evolving female-biased genes defy expectations in mosquitoes
Genes involved in male reproduction tend to evolve rapidly. This has been observed in many different species and is thought to be due to sexual selection as males compete over mating opportunities. But in the August issue of GENETICS, Whittle and Extavour present results that flip this paradigm upside down. They find that in the…

Lineage specific retrotransposons shaped the genome evolution of domesticated rice
Rice is one of the most important food crops on earth. Like many other plants, the genome of this critical global species is dominated by transposable elements—selfish genes that multiply themselves to the detriment of their host. In the June issue of G3, Zhang and Gao analyze the genomic long terminal repeat (LTR) retrotransposon content…

Hot wings and snow birds: Extreme temperature adaptation in domestic chickens
Humans built the modern world with the help of domestic plants and animals. A byproduct of our many domestication experiments is a series of excellent long-term controlled evolutionary comparisons that are helping geneticists understand adaptation. In a study published in the May issue of G3, Fleming et al. identify genomic regions under natural selection in…

MPP People: Andrew Morgan
Multiparental populations (MPPs) have brought a new era in mapping complex traits, as well as new analytical challenges. To face these challenges and encourage innovation, the GSA journals launched the ongoing Multiparental Populations series in 2014. This month’s issues of GENETICS and G3 feature a bumper 16 MPP articles, timed to celebrate a new easy-to-use…

On the cover: Daphnia in the spotlight
Illuminating the cover of the May issue of G3 is a lake-dwelling filter feeder no more than a couple millimeters long. This microcrustacean—Daphnia pulex, also known as the water flea—is an important model organism, especially in ecological genetics. But despite Daphnia’s status as a model organism, no one had examined its population genomics until now.…

50 years of molecular evolution in Drosophila
In the genomic era, population geneticists are flooded with molecular data on the evolution of natural populations. This deluge started in 1966 as a trickle of data from protein electrophoresis studies, including the landmark GENETICS papers published by Richard Lewontin and John Hubby. As Lewontin is honored this week at the Annual Drosophila Research Conference…

The unique genetic variation of the Greenlandic Inuit population could help find novel disease associations
Despite being covered by a massive, permanent ice sheet, Greenland has been continuously inhabited by humans for over a thousand years. Most modern Greenlanders are Inuit whose ancestors migrated eastward from Canada around 1000 AD, bringing technology like kayaks and dogsleds. They eventually settled on the coasts of the world’s largest island, hunting whales and…

Behind the cover: Oh Canada!
February marks the launch of a crisp new look and improved navigation at the G3 website. Go check it out; we’re very proud of the design! We are also unveiling a new cover layout that allows the art submitted by our authors to shine. This month’s cover celebrates the first published genome assembly of the Canadian…

In the Year of the Rooster, a new chicken genome assembly is hatched
The chicken is one of humanity’s closest and oldest allies. With a worldwide population in the billions, this former jungle fowl is one of the most important domesticated animals on Earth. In the February issue of G3, Warren et al. further our understanding of this familiar bird, presenting a new and substantially improved chicken genome assembly…

A modern look at ancient DNA
Well over 15,000 years ago, a man and a bear died in a cave in the Jura Mountains in modern-day Switzerland. That was the end of the story for millennia—until their remains were discovered in 1954 by researchers investigating the cave. Further work in the 1990s uncovered the fact that the man had, in fact,…
