The laboratory for DNA analyses focuses on a large variety of questions in the frame of the institute’s research that can be answered with the help of DNA markers. These include (i) the elucidation of species relationships (molecular phylogeny), (ii) the molecular identification of species and hybrids, especially if morphology is misleading or uninformative, (iii) the development of specific molecular markers for particular groups of organisms, (iv) the understanding of patterns of molecular evolution and intragenomic processes, (v) the investigation of clonal structure in vegetatively reproducing or apomictic species, and (vi) the analysis of population structures, patterns of introgression etc., also in relation to reproductive mode and ploidy of the respective species.
