Analysis of an evolutionary conserved module regulating root system development in monocots and dicot species

Barley (Hordeum vulgare) represents the fourth most abundant cereal harvested. In contrast to wheat species which are mostly polyploid, barley is diploid and therefore easier to be genetically manipulated.
For a crop plant it is important that the root system is sufficiently widespread to be able to absorb enough water and nutrients for the shoot and later on for the fruits. In this project, the root development of barley will be examined. This includes the root length, branching and meristem characteristics. Different ecotypes of barley and recombinant inbred lines will be compared by their roots traits. On the basis of these results, genes which take part in root development will be identified by quantitative trait locus (QTL) analysis.
Furthermore, fluorescent markers for genes and proteins known to be important for root development from Arabidopsis, maize and rice and markers for phytohormones will be introduced in barley to examine their expression in the root.
