Description du projet
Faire pousser des pommes de terre dans des conditions environnementales variées
La pomme de terre est l’une des cultures vivrières les plus importantes au monde. Cela dit, sa vulnérabilité aux stress environnementaux est source de grandes inquiétudes quant à la sécurité alimentaire. Si nous disposons de connaissances limitées des voies combinées de signalisation du stress chez les modèles végétaux comme Arabidopsis, nous ignorons tout de ce phénomène dans les cultures, en raison de leurs mécanismes métaboliques particuliers. Le projet ADAPT, financé par l’UE, étudiera la dynamique des mécanismes complexes de signalisation et de réponse afin d’identifier les mécanismes moléculaires d’adaptation au stress combiné chez la pomme de terre. Le projet élaborera de nouvelles stratégies visant à augmenter la productivité, la stabilité et la qualité dans des conditions de stress multiples. Pour ce faire, il combinera les domaines de la biologie moléculaire, de la physiologie du stress, de la biologie des systèmes et de l’analyse avec l’ingénierie et la sélection moléculaire, en associant des organismes axés sur les utilisateurs qui testeront et mettront en œuvre les résultats du projet.
Objectif
ADAPT identifies molecular mechanisms of adaptation to combined stress in potato to develop new strategies for the improvement of productivity, yield stability and product quality under multiple stress conditions. Potato is one of the most important food crops worldwide and a major constraint to secure yield is its sensitivity to environmental stresses, particularly heat and drought, which is often followed by flooding in the field. Whilst limited knowledge of combined stress signalling pathways is available in model plants such as Arabidopsis, this knowledge is almost completely lacking in crops. These adaptation mechanisms require metabolic reprogramming that is triggered by different signalling pathways. To understand the dynamics of complex signalling and response mechanisms our approach will utilise several technological advances (for example high throughput phenotyping and novel sensor plants). These tools will guide us to the key developmental stages and tissues for in depth analysis allowing unprecedented dissection of these processes. The approach requires complementary expertise from 10 leading academic research institutions with 4 major potato breeders, and a screening technology developer. This unique combination of molecular biology, stress physiology, systems biology and analytics with engineering and molecular breeding as well as the active participation of end-user driven agencies for variety testing and potato trading ensure translation of ADAPT results. Arising from our mechanistic understanding, our expected results will include new breeding targets and the potential to match potato varieties to specific environmental conditions. Knowledge from our research will directly reach the most relevant stakeholders and end-users feeding into breeding programmes and guiding technology development for improved crop management strategies. Thus we anticipate that ADAPT will have a game changing impact on potato breeding and management strategies.
