Research focus

Suboptimal growth conditions caused by drought, temperature, salt and pathogen-related stress are leading to worldwide yield losses in cultivated crops. This problem has a large societal impact (food security) and will become even bigger in the future, as climatic changes will cause more temperature and drought stress, and, while simultaneously the demand for plants for food, feed and bioenergy will steadily increase. Therefore, stress-tolerant crops are in high demand and has incentivized Agbiotech industry in the past decade to significant investments in the search and development of appropriate strategies targeting stress adaptation and protection for the major food and feed crops.

Oxidative stress or the rise in reactive oxygen species (ROS) levels is associated with a multiple of cellular traumas in probably all living organisms. Increased cellular ROS levels can originate from increased production rates through diverse oxidases and peroxidases or from over-accelerated photosynthetic and respiratory electron transport chains. Like other organisms, plants are harnessed with a large and diversified battery of antioxidant mechanisms to detoxify diverse ROS. Genetic perturbations of individual genes of the antioxidant network have demonstrated their key roles in keeping cellular ROS levels under control and ROS have recently emerged as important regulators of plant stress responses. Perturbation in ROS production and/or scavenging are sensed by plant cells as a ‘warning’ message and genetic programs leading to stress acclimation or cell death are switched on. Knowledge on the regulatory events governing ROS signal transduction will reach out towards signaling events in abiotic stress conditions. Through a combined top-down and bottom-up genomics and proteomics approach we are dissecting the gene, protein networks governing ROS signal transduction in plants and pinpoint proteins and pathways that are potential candidates for innovative molecular breeding strategies to develop stress-tolerant crops. In a second line, we study the function of metacaspases and their inhibitors in Arabidopsis thaliana.  These cysteine proteases are in analogy with animal caspases primary regulating or executing plant programmed cell death, next to other developmental and stress-related processes.
