Pernille Bjarup Hansen: Use of multi-omics in plant genetics - is it the key to understand how roots can feed the world?

PhD defence, Friday, 23 October 2020. Pernille Bjarup Hansen.

Pernille Bjarup Hansen

During her PhD studies, Pernille Bjarup Hansen researched the genetics underlying the root growth of important forage grasses and barley. Faster growing and deeper roots helps the plants survive periods of drought. The plant reacts to stresses such as drought by altering the active genes through different mechanisms, such as epigenetic modifications and differential gene expression. Pernille Bjarup Hansen identified genes and clusters of genes related to roots by investigating and integrating different omic layers from DNA to the epigenome and RNA. She also found that different omics could be useful to integrate in prediction models in order to develop more climate stable crops.

The new research findings shows how implementing root phenotyping in modern plant breeding programs can lead to more drought tolerant crops with deeper roots. The use of different omics can be applied even further and useful in order to feed to world in 2050.

The PhD study was completed at Center for Quantitative Genetics and Genomics (QGG), Faculty of Technical Sciences, Aarhus University.
