PhylomeDB has been featured as a tip of the week in the Open Helix Blog.  Thanks to them, a 4-minutes introductory tutorial showing some of the main features of PhylomeDB is available. Don't miss it.

Within the context of the sequencing of the genome of the pea aphid, Acyrthosiphon pisum, we undertook a phylogenetic analysis for every protein of this species. The resulting phylome includes the evolutionary relationships of all predicted aphid proteins and their homologues among 13 other fully-sequenced arthropods and three out-group species. Subsequent analyses have revealed multiple gene expansions that are specific to aphids and may provide hints on adaptations to a particular diet and developmental biology.
