Diving into chilly California waters, understanding genomic differentiation and the role of gene transfer in marine cyanophages

At this point, it’s clear: microbes are everywhere, there are a lot of them, and they are important. In fact, they are more abundant, more diverse and older than any other organism we have on this planet. In particular, cyanobacteria … Continue reading

One of these things is not like the other……

While we know that bacteria are pretty scandalous with their DNA, not minding horizontal gene transfer (HGT) and such (which can be pretty confounding when trying to discuss species concepts), and although it’s clear that this kind of genetic material … Continue reading

Supergenes and Sparrows with Four Sexes

Supergenes are groups of tightly-linked genes that influence suites of traits relevant to fitness. While long a fixture of evolutionary genetics theory, their role in empirical studies of non-model organisms has been relatively limited, due to limitations in both our … Continue reading

A race to the bottom with a new card from the coevolutionary deck

I’m a sucker for a clever, amusing title, though I’ve recently read that amusing titles are cited less (see here). Alas, maybe a well placed metaphor can enliven a manuscript and also not get lost in a citation-less abyss? In basic … Continue reading

Where’s your wine from?

Human-mediated selection of yeast cultures has played a huge role in the development of numerous unique strains of Sacchromyces cerevisiae, often attributed to production of a wide variety of wines the world over. Previous studies have indicated a single domesticated … Continue reading

To sequence a genome or not to sequence a genome, that is the question

In a paper out last month in the Journal of Phycology, Bhattacharya et al. (2015) provide a perspective on the need for more algal genomes. [A] relevant question on the minds of many phycologists might be: do we really need more algal … Continue reading

Et tu, Brute? Black-legged ticks use genes co-opted from bacteria to fight bacterial infection

Horizontal gene transfer occurs when genes are passed between individuals by mechanisms other than reproduction. It is common in bacteria and occasionally happens between highly divergent groups (for example, monocot genes transferred to eudicots, fungal genes transferred to aphids, bacterial genes transferred … Continue reading
