Photobionts of aquatic Peltigera
After a long hiatus, I’ve decided that it’s time to write some updates on the photobiont sequences that have been released over the last few months. I haven’t been entirely idle during the interim and have made a number of … Continue reading

Symbiotic Nostoc Revisited
In the three months or so that I’ve been working on this blog there has been some evolution in the methods I’m using. I though it would be worthwhile to revisit the first group I looked at to see if … Continue reading

Green Algal Photobionts: Trentepohlia
While most work has focused on coccoid green algae and/or cyanobacteria, a largely overlooked lineage of lichen photobionts is the Trentepoliales, a group of filamentous, carotenoid producing green algae. Trentepohlian algae are associated with one fifth of lichen species world … Continue reading

Green Algal Photobionts: Asterochloris.
In this post I will be taking a look at the diversity of the junior partner to Trebouxia: Asterochloris. Originally described by Elisabeth Tschermak-Woess in 1980, Asterochloris was subsequently merged with Trebouxia before being split out again on the basis of sequence … Continue reading

Green Algal Photobionts: Trebouxia
Having beaten the phylogeny of symbiotic cyanobacteria into submission in my previous post, I am now tackling the green algae. My plan was to start with a big-picture analysis of 18S ribosomal RNA sequences, but my initial blast search returned … Continue reading
