Description of the research topic:
Wheat is one of the most important food crop in Hungary and in the world. Its yield can be reduced considerably by abiotic (e.g. heat and drought) and biotic (rust diseases) stresses. One possible way for improving its stress resistance is the transfer of useful traits from wild relatives into wheat by interspecific or intergeneric hybridization.
Wild species of Aegilops, Secale, Agropyron and Thinopyrum are considered as excellent gene sources for wheat improvement, whose several accessions are maintained in the Martonvásár Cereal Genebank. However, the utilization of their genetic potential is hampered by the pure knowledge on their genome structure and the lack of molecular tools allowing the selection of plants carriyng alien chromatin from large wheat/alien hybrid progenies.
In the frame of the research carried out at Martonvásár, we are developing high-resolution Genotyping-by-Sequencing (GBS) marker systems using next-generation sequencing. We combine these genomic tools with automated molecular cytogenetic methods (GISH/FISH) to select lines carrying alien chromatin among derivatives of wheat x alien crossing programs. We develop a set of wheat/alien chromosome addition, substitution and translocation lines. The disease resistance and drought- and heat tolerance of the selected lines are tested in field and greenhouse environments. As part of the interdisciplinary research project, the student will have the opportunity to apply and learn the methods used in the field of sequencing, bioinformatics, molecular cytogenetics, interspecific hybridization, stress physiology and breeding.
