PhD position on resistance gene identification in wheat

University of Natural Resources and Life Sciences

Fusarium head blight is one of the most destructive diseases of wheat (Triticum aestivum) leading to severe losses in both yield and crop quality. Moreover, the causative fungi of the genus Fusarium produce mycotoxins that accumulate in the grains and constitute a serious threat to food and feed safety. Hence, controlling this disease is of pivotal importance and growing resistant varieties is a sustainable, environmentally friendly and cost- effective approach.

Although FHB resistance QTL have been genetically mapped more than 20 years ago, the genes controlling this disease are largely unknown. In wheat, gene isolation and functional validation is especially challenging due to the huge genome size and polyploidy.

In a project funded by the Austrian Science Fund (FWF) we aim to resolve a Fusarium resistance locus via CRISPR/Cas-induced mutagenesis and extensive transcriptome analysis. Defined alterations in the candidate region will be generated and evaluated for their functionality. We will combine short- and long-read RNA sequencing technologies with quantitative PCR to characterize the gene model and identify causal transcripts for resistance.

The PhD student will be involved in work focusing on transcriptomics, RNA-seq data analyses and RT-qPCR. The student will also be trained in genome editing and tissue culture and perform phenotyping trials of mutants.

Project team: Dr. Barbara Steiner, Prof. Hermann Buerstmayr experts in ‘Fusarium research’, Prof. Eva Stöger, Dr. Eszter Kapusi expertise in genome editing, Prof. Heinz Himmelbauer, Ass.-Prof. Juliane Dohm, Dr. Maria Kalyna support RNA-seq data analysis.
