Biografie

My research focuses on understanding how branches (tillers) and seeds are formed in cereals. Cereals are important crops, which are grown worldwide for food and feed. Cereal crop yield is controlled by the number of spike bearing tillers, the number of seeds per spike and seed weight. Yield components such as seed and tiller number, but also seed weight, are negatively correlated: More seeds often results in fewer tillers, or a reduction in seed weight. These kinds of negative correlations make it difficult for breeders to improve yield via modification of the individual yield components. What causes the negative correlation between these yield components and can we uncouple them? Addressing this question is important for the development of knowledge-based breeding strategies to improve cereal crop yield. My research uses molecular and genetic approaches to identify the key regulatory genes and pathways that control the formation of multiple yield components such as seeds and tillers. Together, this gives novel insights into the molecular basis underlying the trade-off between seed and tiller number. This knowledge can be utilized to improve cereal crop yield.

VENI: Branching controls yield in barley

Small grain cereals such as barley and wheat are important crop species for food and feed supply. Cereal crop yield depends on traits such as the number of seeds per spike, the number of side shoots (tillers) and seed weight. These traits are often negatively correlated which makes improvement of yield difficult. Recent discoveries indicate that the same genes affect both seed and tiller number. Optimizing yield by changing these traits is possible, but will require an in-depth and fundamental understanding of the molecular mechanisms that affect both inflorescence and shoot branching. 
The regulation of branching has been well studied in model systems like Arabidopsis and rice. In comparison, little is known about the regulation of branching in small grain cereals such as barley and its close relative wheat. The overall objective of my research is to understand how the same genes or regulatory modules affect both seed and tiller number in barley, an emerging model system for small grain cereals.
