Mayrose Lab: Home

Welcome to our lab!

Our main research interests are concerned with the broad field of plant evolution and phylogenetics. We use comparative bioinformatics approaches to gain insights into the fascinating evolutionary dynamics of plant genomes. We are also interested in developing computational tools that can be used to gain novel biological insights from various kinds of data. For more detailed information see the Research page.

August 2016
We find that polyploidy occurs more often in plants that have been domesticated. Read it all here and in this News&Views

Our study on Sex determination in reptiles reveals the complex patterns by which sex determination affect lineage diversification.

July 2016
Two of our studies appear in a special issue on polyploidy in the American Journal of Botany: We investigated a large number of flowering plant genera and found that polyploidy is broadly associated with sexual system dimorphism (or, dioecy). We found some phylogenetic support for the hypothesis that polyploidy instantly leads to reproductive isolation.

A new version of ConSurf was launched. See the manuscript for all details.

June 2016
In our paper on sex-determining mechanism in reptiles (genetic or temperature-dependent) we suggest no effect of the sexual system on diversification patterns, rather, differences in species richness are mediated by differences in longevity and transition rates.

Dioecy does not seems to systematically change diversification rates in flowering plants. Read it all here
