Impressions of a workshop: New model systems for early land plant evolution, 22 – 24 June 2016, Vienna, Austria

A couple of weeks ago I spent a few days in Vienna, my first visit in 11 years, when I was last over for the 2005 XVII International…

Capturing Genes from Herbaria. XI. Some metagenomics of a herbarium specimen

As part of our hybrid capture project, we sampled from an Inga umbellifera specimen that was collected about 180 years ago, by Andrew Mathews, in Peru in 1835….

The complex thalloid liverwort Aitchisoniella, and its place in the tree of life

The genus Aitchisoniella contains a single species, A. himalayensis, which was described by Pakistani botanist Professor Shiv Ram Kashyap from plants that he collected in Mussoorie, Uttarakhand, India…

Capturing Genes from Herbaria. X. An update.

Last May (the 15th, to be precise), we sent three eppendorf tubes containing Illumina Tru-Seq and NEB-Next libraries constructed from Inga DNAs, most of which had been extracted…

In plain sight – the mosses that grow on British walls

Plant diversity does not have to be far-flung and exotic to be worth studying; even within Scotland, there are unanswered questions about plant distributions. Growing in our towns and…

The Aneura Working Group meeting, Trondheim, 8th-12th February 2016

Sitting in Edinburgh airport on a Monday morning, waiting for David Long to join me, checked in through to Trondheim via Copenhagen, I felt completely unprepared. The previous week…

There’s more to Marchantia than there used to be! An introduction to the new additions

One of the most recognisable groups in the bryophytes, the complex thalloid liverwort genus Marchantia, has just become a bit larger. We have sunk Preissia and Bucegia into…

A mixed message on PCR additives in Aneura

This last week I’ve actually managed to spend a bit of time in the lab, trying to get some gaps filled in a DNA barcoding matrix for simple…

Lost before found: Was there more than one species in Monocarpus?

The complex thalloid liverwort Monocarpus sphaerocarpus has been found on two continents, Australia and Africa, separated by around 8,000 km of mostly ocean. The green plants themselves are…

Rates of change in liverwort genes

Although the exact relationships between the earliest land plant lineages are not yet well resolved, there is consensus that liverworts are one of the most ancient land plant…

Oh blast – there’s more to life than Marchantia polymorpha

One of the earliest plastid genomes to be sequenced, in the late 1980s (Ohyama et al.), was that of Marchantia polymorpha, one of the commonest liverworts around town,…

Scientific progress, continental drift and glaciers: The history of a paper on the complex thalloid liverworts

Rather a while ago, back in 2003, we started working on a phylogeny of the complex thalloid liverworts at the Royal Botanic Garden Edinburgh (as a Molecular Phylogenetics…

Hidden diversity in unexpected places – moss growth on modern building surfaces

Back in 2014, staff in the molecular lab and herbarium at RBGE greatly enjoyed a three-week visit from Austrian Dr Wolfgang Hofbauer. With funding from the EU SYNTHESYS…

Capturing Genes from Herbaria. IX. Hybrid capture

By mid-May 2015, we had 32 separate Inga umbellifera libraries, 15 generated using the Illumina Tru-Seq Nano library preparation kits, and 17 with the NEBNext Ultra library preparation…

Finding Monocarpus, in the field

Sadly, although not surprisingly, I was not able to amplify the regions of Monocarpus DNA needed to compare it to other complex thalloid liverworts from a 1950s collection that we had…

Finding Monocarpus, in the herbarium

At the Royal Botanic Garden Edinburgh we’ve been working on the phylogeny of the complex thalloid liverworts for rather a while now. David Long presented a poster on…

On Monocarpus

As far as liverworts go, Monocarpus is a rather strange plant. It’s very small, in itself not that unusual for a bryophyte, but rather problematic if you need…

Capturing Genes from Herbaria. VIII. Amplification

Both the Tru-Seq and NEB libraries were amplified pre-hybrid capture – another step at which modifications were made, according to how much DNA there was in each library….

Capturing Genes from Herbaria. VII. Comparisons.

As previously mentioned, we tested two different kits in our NBAF project. The first is the Illumina Tru-Seq Nano library preparation kit (FC-121-4001), which recommends a starting DNA…

Capturing Genes from Herbaria. VI. Size selection

A few days ago, I read a tweet from the Botany2015 meeting in Alberta that described DNA extracted from herbarium specimens as “pre-sheared”. This resonates with our own…
