The title and a brief outline of the session contents are indicated along with the member of the scientific committee responsible for that session.

Session 1:Evolutionary history and speciation (Judith Fehrer)
Phylogeny, reticulate versus cladogenetic evolution, gene trees, taxonomic consequences and distribution of polyploidy
Session 2:Meiosis, embryology, reproduction and apomixis/parthenogenesis (Anna Koltunow)
Mechanisms of polyploid formation, maintenance, and development; population structure of partial asexuals
Session 3:Analysis and modelling of population structure (Brian Husband)
Approaches for molecular data analysis of mixed ploidy populations; ecology and dynamics of polyploid or mixed-ploidy populations
Session 4A:The long- and short-term evolutionary genomics of polyploidy (Andrew Leitch)
Effects on genome size, gene composition, intergenomic recombination and gene conversion, chromosome and genome structure, comparative genomics
Session 4B:The long- and short-term evolutionary genomics of polyploidy (Jonathan Wendel)
Effects on gene expression, sub- and neofunctionalization, genomic dominance, combinatorial possibilities
Session 5:The epigenetic basis of natural variation (Aleš Kovařík)
Chromatin epigenetic markers, small RNA world, epigenetic networking, epigenetics and development
Session 6:Polyploid phenotypes (Jaroslav Doležel)
Influences of polyploidy on physiology, flowering, evo-devo, ecological adaptation, metabolome, crop improvement, breeding programs
Session 7:Hybridization, polyploidy, and invasiveness (Malika Aïnouche)
Ecology, genetics and genomics of hybrid and polyploid invasives; impacts on biodiversity

Oral presentations (all sessions): In addition to the above-mentioned committee members, Maurine Neiman will participate in the selection of contributed talks on organisms other than plants. Abstracts whose authors have expressed interest to publish their data in the special issue of Heredity will additionally be evaluated by Barbara K. Mable (handling editor).
