----------------------The 2017 EDUARD STRASBURGER WORKSHOP----------------------


The genome within a cell dictates its overall operations. Such programming might come into a challenge in the presence of an additional genome that is slightly or entirely different from the initial one. Thus the question arises which of these two genomes succeeds in enforcing its information and whether both genomes cooperate or if conflict prevails?

A mixed genome setup can arise through different phenomena, the most prominent example being hybridization. Hybrids are the offspring of genetically distinct parents and often exhibit phenotypic superiority and improved fitness. This is the reason why many agricultural important plants are hybrids. However, many hybrids and polyploids suffer from “hybrid incompatibility” which is manifested through decreased fertility and hence inviable offspring (Dobzhansky, 1936; Muller, 1942). Cross fertilization of different strains, varieties or even species often leads to a change in ploidy level (e.g. cotton and wheat). These processes of interspecific hybridization and polyploidization also occur naturally and contribute to genomic variability bearing the consequence of establishing mechanisms for adaptation and speciation (Soltis, 2000). The breeding of hybrids is not the only example to gather two distinct genomes in one cell. Indeed, the same outcome follow horizontal gene transfers by bacteria, viruses and even endophytic fungi. Even though research in the last century provided many insights into these topics, the genetic basics of these phenomena remain poorly understood.

The Strasburger Workshop 2017 will gather breeders as well as evolutionary and developmental biologists and will encompass in depth seminars and discussions focusing on these topics to strengthen further understanding of genome plasticity. This workshop offers the opportunity to establish connections to find solutions and improvements for individual projects and to start new projects. Furthermore, it provides the opportunity for young scientists to exchange their experiences, techniques and gather knowledge while exploring the principles underlying the union of two genomes in one cell.
