Of dups and dinos: evolution at the K/Pg boundary

Fifteen years into sequencing entire plant genomes, more than 30 paleopolyploidy events could be mapped on the tree of flowering plants (and many more when also transcriptome data sets are considered). While some genome duplications are very old and have occurred early in the evolution of dicots and monocots, or even before, others are more recent and seem to have occurred independently in many different plant lineages. Strikingly, a majority of these duplications date somewhere between 55 and 75 million years ago (mya), and thus likely correlate with the K/Pg boundary.

Seminar by Prof. Yves Van de Peer: 'Of dups and dinos: evolution at the K/Pg boundary'

Genome sequencing has demonstrated that besides frequent small-scale duplications, large-scale duplication events such as whole genome duplications (WGDs) are found on many branches of the evolutionary tree of life. Especially in the plant lineage, there is evidence for recurrent WGDs, and the ancestor of all angiosperms was in fact most likely a polyploid species. The number of WGDs found in sequenced plant genomes allows us to investigate questions about the roles of WGDs that were hitherto impossible to address.

ALPHY (ALignments and PHYlogeny) 2016

ALPHY 2016: French-Belgian meeting on Bioinformatics and Evolutionary Genomics

Important date: Deadline for abstract submission, travel grant application and registration: January 15 2016

ALPHY is an annual meeting, organized in France since 1995, dedicated to the field of Bioinformatics and Comparative Genomics (ALPHY = ALignments and PHYlogeny). The main goal of this meeting is to promote informal communication in this highly multidisciplinary field, and to encourage young scientists to present their work.
