DESCRIPTION:Speakers: Ingo  Schubert (Leibniz Institute of Plant Genetics 
 and Crop Plant Research (IPK)\, Gatersleben)\nThe shortest definition of e
 volution is maintenance and expansion of information by the change of info
 rmation (mutation) and subsequent selection (by environment). On the bioti
 c (post-cellular) level\, evolution led to +/- sexually isolated populatio
 ns of individuals\, called species. While karyotypic mutations can initiat
 e speciation\, genic mutations lead to allele diversity and adaptability. 
 The main reasons for karyotype mutations (and thus for speciation) are mis
 -repaired DNA double-strand breaks.            Another important route of 
 speciation is reticulate evolution by fusion of (reduced or unreduced) gam
 etes from different species.\nOur actual collaborative efforts to resolve 
 the phylogeny of duckweed genera demonstrate how these principles of evolu
 tion shaped duckweed diversity in the past and that they are still ongoing
