John Hutton Balfour Excursions

“Excursions may be truly said to be the life of the botanist. They enable him to study the science practically, by the examination of plants in their living state, and…

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…

Dry tropical forest movie making

  Seasonally Dry Tropical Forests are found throughout Latin America from Mexico to south-western Brazil and northern Argentina. Dry forest is the world’s most threatened tropical forest due to…

300,000 specimens imaged and online!

Yesterday saw the 300,000th specimen from our herbarium collection imaged and made available on our website. This is a big milestone for the digitisation programme, which has been…

Wartime Rhododendron

  In the Autumn of 1914, George Forrest was travelling in China. His letters written at the time mention the difficulties he was facing in getting permission to…

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…

Amorphophallus titanum – Preserving it for posterity

The flowering of our Amorphophallus titanum (titan arum) was a tremendous event with c 19,000 people visiting the Glasshouses to see the plant growing from a small bud…

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…

British Algae online

Here at the RBGE we have just finished digitising our collection of British Rhodophyta (Red Algae), a total of 7850 specimens. Our collection dates from present day right…

Capturing Genes from Herbaria. V. Fragmenting the DNA

The mantra for many years for next generation sequencing has been, like “garbage in, garbage out”, that the optimal starting point is high quality, high molecular weight DNA….

Capturing Genes from Herbaria. IV. DNA

In March this year, having already chosen and obtained the plant material that we were going to use for our NBAF project on using a hybrid bait protocol…

Capturing Genes from Herbaria. III. The Samples.

Having chosen Inga umbellifera as the study organism for our NBAF-funded project to test the use of hybrid baits for recovery of DNA sequences from herbarium material, we…

Capturing Genes from Herbaria. II. Inga.

About 300 species of Inga (Leguminosae: Mimosoideae: Ingeae) grow in lowland and montane rain forest throughout the humid tropical zone, from Mexico to Uruguay. Most species diversity is…

Capturing Genes from Herbaria. I. What it’s all about.

In February this year, Dr Catherine Kidner, Dr Michelle Hart, Dr James Nicholls and I were awarded an NBAF pilot grant by NERC to explore the use of…

Digitising microscope slides – barcode placement

As part of the digitisation of the collections held at RBGE we are starting to barcode our microscope slide collections. As part of this we have been investigating…

Biology, genomics and evolution of the complex thalloids

Twenty-five participants from 13 countries have just attended a symposium on complex thalloid liverworts in Edinburgh #Marchantia2015. The meeting also included two teleconferences (from Australia, John Bowman, Monash…
