One Thousand Plant Transcriptomes and Not a Single to Spare
What is the weight of a transcriptome? How about a thousand? Every day new sequencing machines are purring away, base pair by base pair, producing novel insights into the genomes of our favorite organisms. As technology improves, costs come down, and opportunities … Continue reading

Polyploidy in the era of GBS
Ploidy, dear reader, is something that I think about literally all the time. It impacts every facet of my research from the field to the bench to the stats used to analyze data sets. It’s been simultaneously the greatest and the … Continue reading

Fungi and the quest for old polyploids
Polyploidy, that curious increase in a species’ number of genomes, is now a well recognized force in the evolutionary history of plants and animals. Those extra genomes are often much more than just extra: having a spare genome or four … Continue reading
The slow, and sometimes incomplete, journey to diploidy
Whether you are reading this as a plant, an animal, or fungus, it is likely that some ancestor of yours doubled up on genomes. However, it is likely that these extra genomes disappeared over evolutionary time. What gives? Where are those extra … Continue reading

Paternity matters in polyploid plants
In the most basic definition, polyploidy is a numerical increase in whole chromosome number. The effects of this increase in genomic material often produce novel morphologies compared to parental species, and polyploids have become both a huge part of explaining the … Continue reading
Live from London: reporting from "Elements, genomes, and ecosystems"
Scientific meetings are great: see old friends, meet new colleagues, sow the seeds of collaboration, see interesting work from around the world, and so on. They’re fun, they really are. But they can be so big. The annual meetings of the … Continue reading
