Algal Bioinformatics at Shantou University, Shantou China

Published on: Author: Charles Delwiche Leave a comment

Graduate student Charlie Goodman and I have spent the last two weeks teaching a class titled “Algal Bioinformatics in the Context of Climate Change” at Shantou University in Shantou, China. Organized through the Shantou University – Universitá Politecnica delle Marche (Ancona, Italy) Joint Algal Research Center, the class was sponsored by the Shantou University College of… Continue reading

Chara genome!

Published on: Author: Charles Delwiche Leave a comment

Chara is a large and structurally complex green alga that is common in streams and ponds worldwide.Chara the other stoneworts (Charophyceae sensu stricto, or Charales sensu Mattox and Stewart) form an important component of the freshwater flora, and have superficial structural similarities to land plants. In 2001 our lab published a paper indicating that the… Continue reading

Review of Eukaryotic Microbial Diversity Out in BioEssays

Published on: Author: Charles Delwiche Leave a comment

Our recent publication in Bioessays, “Microbial Diversity in the Eukaryotic SAR Clade: Illuminating the Darkness Between Morphology and Molecular Data” was a collaborative effort between the Delwiche, Lane, and Katz labs. SAR taxa are members of the clade that includes Stramenopiles, Alveolates, and Rhizaria. These organisms comprise a major component of eukaryotic diversity, but because… Continue reading

Cell Preview of the Marchantia Genome

Published on: Author: Charles Delwiche Leave a comment

A first comprehensive analysis of the Marchantia genome was published today in Cell. Marchantia is a thalloid liverwort, a representative of a lineage of land plants that is among the earliest diverging groups of land plants. The relationships among ‘bryophytes’ (i.e., haploid dominant land-plants, including liverworts, hornworts, and mosses) remains uncertain, but liverworts are a strong… Continue reading

Collecting Dinoflagellates in Florida

Published on: Author: Charles Delwiche Leave a comment

The lab went on a week-long collecting expedition to Florida in early August, with our primary goal being to collect some understudied, warm-water dinoflagellates. We collected in both freshwater and open ocean environments, isolating single cells with drawn glass capillaries. We won’t really know how successful the expedition was for several months as we work… Continue reading

Major Transitions in Dinoflagellate Evolution

Published on: Author: Charles Delwiche Leave a comment

Our collaborative paper on dinoflagellate evolution has now appeared in PNAS: Major transitions in dinoflagellate evolution unveiled by phylotranscriptomics Jan Janouškovec did a terrific job summarizing the current state of knowledge of dinoflagellate phylogeny and the implications this has for character evolution within the group. I think this paper is a significant contribution in dinoflagellate… Continue reading

Nice Nature News & Views on the Palmophyllophytes

Published on: Author: Charles Delwiche Leave a comment

The Palmophyllales are recently discovered and poorly understood deep-sea green algae that are phylogenetically close to the base of the green algal tree. An excellent new paper from Fred Leliaert looks at chloroplast genomic data from Verdigellas peltata (out of a specimen dredged up during the Deep Water Horizon oil spill) and places the organism in a… Continue reading

Book review in BioScience — Biocode: The New Age of Genomics

Published on: Author: Charles Delwiche Leave a comment

I have a book review coming out next month in BioScience (the publication of AIBS, the American Institute of Biological Sciences, which is a good organization that works toward integrating the life sciences). The text of the review is below. The copyright agreement allows me to present the text here, but to see the typeset… Continue reading
