The Leymoid genera
The Leymoids are consisting of those species and genera that at one time or another have been considered to possess a genome identical or highly similar to that found in Leymus species. This genome is called JN (Dewey 1984, Löve 1984) or NsXm (Wang et al. 1996). Several resent studies indicate that the two haplomes are higly similar and may represent variants of a single haplome – here called N. The Leymoid group is not thought to be a monophyletic group. It is merely an assemblage of taxa that make up a start point for an investigation of the phylogenetic relationships in the Triticeae, focusing on the "forgotten" polyploid Leymus-complex.
In this project we aim at resolving natural groups within this very diverse complex using a multi-methodological approach, including molecular markers, in-situ hybridization, gene sequencing, and a reexamination of macro- and micro-morphological characters.
