Cardamine hirsuta: a new system for evo-devo studies.

If you have a question about this talk, please contact Matt Box .

A key question in biology is how differences in gene function or regulation produce morphological variation during evolution. Cardamine hirsuta – a plant related to the model organism Arabidopsis thaliana – is a powerful new experimental system for investigating this question. Our research aims to determine the genetic basis of divergence in floral structure between A. thaliana and C. hirsuta, which differ in stamen and petal number. We are using a combination of mutagenesis and quantitative trait locus analysis to uncover the genomic regions underlying both induced and natural variation in C. hirsuta floral structure. This work should provide an exciting opportunity to understand how gene regulatory networks are reconfigured during evolution to produce divergent morphologies.
