More population genetics of polyploidy!

I did a literature search today and found several interesting papers. I picked two for next week, but in the interest of time, I think we should focus on the first one (Walsh paper). The Comai paper can be background reading for people who want to do a little polyploidy catch-up (like me). Both Genetica and Nature Reviews Genetics are available online through the library.

I read the beginning of this paper and scanned the rest. It addresses some of the ideas we touched on at the end of the April 10th class. It gets real mathy at the end, but it seems like a well-written paper (aka focus on the text and slide over the math parts).

Nice review, lots of pretty pictures of difficult to visualize inheritance mechanisms. Introduces some molecular genetic concepts not covered in other two papers.

Ploidy shifts with Pat and Brian.

The yeast haploid superiority article (Zeyl, 2003, Science below) dovetails nicely with the Walsh reading from April 17 and the Otto review from April 10.

A recent paper on gene duplicate evolution in Teleost fish should further expand on experimental observations related to evolution specific to polyploid contexts.

Speciation with Dena

Great paper from the Solti, Pires, and Leitch groups from a meeting proceedings at Kew Gardens. Demonstrates that in this case the species barrier was not overcome just once in a freak accident.

Polyploid tree frogs unite to form a complex interspecies swarm. Demonstrates recurrent polyploid formation can play a role in animal polyploid speciation too. Go frogs.
