My research is focused on microevolutionary processes in family Rosaceae with special emphasis on the role of polyploidization, hybridization and apomixis.

My model groups are genus Prunus and genus Cotoneaster. In genus Prunus , I am focused on crop-to-wild hybridization of wild Prunus fruticosa with cultivated sweet and sour cherries and its impact to plant conservation.

In genus Cotoneaster , I am interested in cytotype distribution and variation in reproductive pathway and its contribution to Western Carpathian Cotoneaster taxa delimitation. Especially my research includes Cotoneaster integerrimus agg. CV , ResearchGate. My research focuses on the origin of polyploids of southern African Oxalis , polytopic polyploid origins of Arabidopsis lyrata and diversification across hybrid zones mainly a hybrid zone between Arabidopsis arenosa and A.
The project deals with the role of hybridization and allopolyploidy in generation of plant diversity on the examples from the three Brassicaceae tribes. We will address genomic, phenotypic and ecological consequences of within- and across-ploidy crossing and assess its relevance for plants growing in their native environment. Multiple methodical approaches, namely genomic techniques RAD seq, Hyb-Seq, enabling targeted sequencing, microsatellite markers , genomic in situ hybridization GISH , FISH and chromosome painting - CCP , DNA content genome size measurements, multivariate morphometrics, artificial hybridization, ecological and climatic niche modelling will be used.

Important advantage is the detailed knowledge of the plant systems by the team, including their evolutionary history, experience with proposed methods in the studied genera and already available plant material for DNA analyses. The project deals with triggers and consequences of polyploidisation whole genome duplication on the example of three polyploid complexes of Brassicaceae. Analysis of the influence of cryptic variation of diploid and independently arisen polyploid lineages, together with ecological and morphological consequences of polyploidisation, and influence of selection on genomes of di- and polyploid lineages is carried out.
For the Cardamine pratensis complex, evolutionary potential of dysploidy is also estimated. Advanced genomic techniques RAD seq, target enrichment, genome resequencing , comparative chromosome painting CCP , ecological experiments and bioclimatic modelling are used. Speciation both at the diploid and polyploid levels is examined, elucidating the role of genome merge, duplication, and hybridisation, together with geographical and ecological separation. In particular, they are focused on understanding a non-canonical mechanism of auxin signalling involving the auxin response factor, ETTIN.
In addition to the academic satisfaction of understanding biological processes, the knowledge acquired during studies of fruit development among Brassicaceae provides an enormous potential for knowledge transfer to improve crop performance.
Lars has already demonstrated the power of such a translational approach. Work in his group first demonstrated that the genetic control of seed dispersal is conserved across members of the Brassicaceae family. Subsequently, they used this knowledge to control this process in oilseed rape, which is known as pod shatter. Seitenauswahl Anreise Stellenangebote Konferenzen Mitarbeiter.
