Adding host information to the Nostoc phylogeny

Having obtained 496┬áNostoc rbcX sequences (plus one outgroup) and used them to infer a reasonable phylogeny, all that is left is to assign host association information to the branches. This will require (a) parsing the sequence files to obtain host … Continue reading

Welcome to PhotobiontDiversity

As with most organisms, DNA sequencing has revolutionised our understanding of the genetic diversity and phylogenetic relationships of lichen photobionts over the last two decades. However, unlike most organisms, these insights have rarely been translated to formal taxonomic changes and … Continue reading
