Results in brief

Deciphering the role of oxylipins in the epigenetic mechanisms controlling plant immunization.

Reducing crop losses caused by pests and diseases is necessary in order to produce more food in less land, ensuring food security while avoiding the overexploitation of natural resources. As a result, international entities such are promoting the search for alternative strategies. Experts point to “plant immunization” or priming, as the safest and most effective approach. After a first infection plants respond more effectively against a second pathogen encounter, what is known as priming. This implies certain “memory” of the first stimulus in order to better respond to subsequent attacks in an adverse environment. Different priming processes have been described, being the first stimulus ‘remembered’ from short to long periods of time, and even transmitted to the next generation of plants. Unfortunately, deeper knowledge of the involved mechanisms is needed for its application in crop protection. In this context, the plant intracellular cascade occurring between the perception of the pathogen and the fingerprinting of the stress memory still uncertain. Epigenetic mechanisms and oxylipin pathways are involved in priming processes, but their specific contribution as well as the relationship between these two pathways had not been addressed to date. To fill this gap in our knowledge, we have carried out an ambitious project using the unique genetic and molecular tools available in the model plant Arabidopsis thaliana to analyse first the role of oxylipin natural compounds in priming processes and then, to study the relationship between both molecular pathways to delineate plant defence mechanisms and the memory of the stress.

Project objective

Reducing crop losses caused by pests and diseases is absolutely necessary to feed the increasing world population, but the use of pesticides increases the damage to the environment and contributes to climate change. As a result, international entities such as the European Union are promoting the search for alternative strategies. Experts point to “plant immunization” or priming, as the safest and most effective approach to boost the endogenous plant immune system. Unfortunately, deeper knowledge of the involved mechanisms is needed for its application in crop protection. In this context, epigenetic mechanisms and oxylipin pathways are involved in priming processes but their specific contribution as well as the relationship between these two pathways has not yet been addressed. In order to fill this gap in our knowledge we propose an ambitious but feasible project that builds on solid and exciting preliminary results. We will use the unique genetic and molecular tools available in the model plant Arabidopsis thaliana to analyse first the role of oxylipin natural compounds in different priming processes and then, study the relationship between both molecular pathways to delineate plant defence mechanisms and priming. The synergistic interaction formed by the host group, world-leading in oxylipins research, and the applicant, an expert in epigenetics, guarantees the maximization of two way transfer of knowledge, training and networking possibilities. Moreover, this action has a potentially remarkable impact and represents a key point in the applicant´s career complementing her current knowledge and expanding her skills. Taking these considerations together, the EPILIPIN project offers a unique opportunity for the development of a research that perfectly fits the EU concerns and priorities of improving crop yields minimizing the impact of agriculture on the environment by exploring the use of natural compounds (oxylipins) to trigger long term immunization (priming).
