One Thousand Plant Transcriptomes and Not a Single to Spare

Posted on 3 Feb, 2020 by R Shawn Abrahams

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

Posted on 23 Mar, 2017 by Stacy Krueger-Hadfield

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

Posted on 17 Nov, 2016 by Rob Denton

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

Posted on 27 Apr, 2016 by Rob Denton

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 →

To find duplicated loci in vertebrate polyploids, try thinking small

Posted on 23 Mar, 2016 by Rob Denton

Big sequencing efforts have gone a long way to help understand the complexities of polyploidy. However, the bioinformatic approaches to sorting and scoring alleles in next-gen data are generally designed for easy of use in diploid species. Unlike a diploid species, where … Continue reading →

Paternity matters in polyploid plants

Posted on 30 Sep, 2015 by Rob Denton

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"

Posted on 3 Jun, 2015 by Rob Denton

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 →
