Mapping genes onto a species tree?

Question

[ellis.moloney]

Hello all,

I am brand new to bioinformatics and seem to have got lost in all the jargon/different types of analysis.

Basically, I want to create a classic phylogenetic tree of multiple species (same phylum) and then map onto that tree which of those species have specific stress related genes (each one with a colour coded symbol) and what the evolutionary history of those genes are on that tree i.e. when did they arise.

So, at the tips of the tree will be the names of each species with a colour coded symbol next to it to show which species has which gene(s). Then as you look further back in the tree, those symbols appear again whenever the gene arose. This would allow me to see which genes are the most common across species and also how conserved they are through time.

I am looking for someone to help point me in the right direction in terms of whether this is even possible and what software/methods I should look at to get started!

The genomes I will be using will be comprised of some which are fully annotated and some which are not, if this helps.

Thanks in advance!

Ellis

Check out iTOL, a web application to draw trees that includes the functionality you require.
