TL;DR:
Comparison of 4300 random shotgun sequence fragments of the Arabidopsis thaliana Ler ecotype genome with the whole genomic sequence of the Col-0 ecotype identified 60 genes with putatively high levels of intraspecific variability, three of which were found to display elevated levels of nucleotide polymorphism.

TL;DR:
Coalescent simulations indicate that ancillary morphological innovations associated with self-pollination can evolve rapidly after the inactivation of the self-incompatibility response, and suggest that the post-Pleistocene expansion of A. thaliana from glacial refugia may have been associated with this adaptive event.

TL;DR:
Investigations on the relationships between network organization, topological architecture and evolutionary dynamics provide intriguing hints as to how networks evolve.

Open access is the free, immediate, online availability of research
articles. Making your research open access allows researchers across
to globe read and interact with your work which may increase citations
to your work.
Citation Index includes data from a number of different sources. If you have questions about the sources of data in the Citation Index or need a set of data which is free to re-distribute, please contact us.
