JC: Bud's buds

An atlas of over 90,000 conserved noncoding sequences provides insight into crucifer regulatory regions by Haudry et al. (2013). 

My comment:
Conserved noncoding sequences are interesting because they reveal something about selection. In this comparitive case though I'm more interested in what distinguishes these genomes. In particular, this vague connection that the authors allude to that the candidate for differential genome size is transposable elements. And, I guess on a telelogical level, it's like what is their purpose!?

Also, can these crucifer species be crossed to another? Can A thaliana and A. lyrata (it says they are congeners)?
