Research Intrest

Our lab investigates how plants employ their immune system to adapt to environmental stress. Plants in relatively stress-free environments invest most of their resources in growth and reproduction. If plants live in hostile environments, and are attacked by harmful microbes or insects, they activate inducible defence mechanisms. Activations of these defences is often costly, due to allocation of limited resources to defensive compounds, or toxicity of the defence response to the plant's own metabolism. Plants are also capable of acquiring a less costly form of resistance, which can be activated after perception of environmental alarm signals that sensitise the plant's immune system. This 'defence priming' results in a faster and/or stronger defence reaction when the plant is attacked at a later stage. Research in our lab is divided between four themes. We have a long-standing interest in the mechanisms by which priming-inducing chemicals (such as beta-aminobutyric acid (BABA)) trigger immune priming. This work led to the discovery of the BABA receptor, which controls broad-spectrum disease resistance and plant growth via separate signalling pathways (Luna et al., 2014). A large section of the lab investigates the epi-genetic basis of immune priming, which stems from our previous discovery that heavily diseased Arabidopsis plants can prime the immune system of their progeny (Luna et al., 2012). Current efforts focus on the role of DNA methylation in disease resistance (Lopez et al., 2016) and transgenerational immune priming. A third line of research focuses on the role of root exudation chemistry in shaping disease suppresive microbial soil communities. Part of this work focuses on the role of benzoxazinoid exudates in shaping root microbial communities in maize (Neal et al., 2012). Finally, we collaborate with agricultural companies (such as ENZA Zaden) to translate our basic research and optimise crop protection through novel defence priming strategies (Luna et al., 2016).
