The phylogenetic tree below is from Koenig and Weigel 2015. Beyond the thale: comparative genomics and genetics of Arabidopsis relatives. Nature Reviews Genetics 16:285-298. Plants with genomes completely sequenced are highlighted in red. What word describes the grouping of the taxa which have had their genomes completely sequenced?

Solution

Taxon, Taxon specific genes that have been sequenced and found to be closely related have been grouped together in a phylogenetic tree. The taxon-specific gene based approach provides a methodology to carry out the taxonomic classification of newly sequenced or existing genomes of both prokaryotic and eukaryotic organisms.
