Analyse de génome pour l'amélioration des plantes

A l’horizon 2050, l’agriculture devra nourrir plus de 9 milliards de terriens alors que dans le même laps de temps le changement climatique et la réduction des surfaces cultivables se poursuivront. L’une des solutions qui permettront de faire face à ce défi historique, est l’utilisation de nouvelles variétés de plantes, à la fois plus productives et plus respectueuses de l’environnement.

Pour pouvoir les développer il faut identifier au sein des variétés actuelles, cultivées mais également sauvages, les caractères d’intérêts (rendement, résistances aux maladies et aux événements climatiques extrêmes)  et découvrir les gènes et les mécanismes moléculaires qui les gouvernent. Ce travail requiert la combinaison des nombreuses approches telles que le génotypage, la génétique, la biologie moléculaire.

Au cœur de cette recherche pluridisciplinaire, le CNRGV offre l’accès aux ressources génomiques et propose son expertise aux acteurs de la recherche publique comme aux entreprises privées. Le CNRGV s’implique dans des projets de toutes dimensions depuis l’identification d’un gène d’intérêt jusqu’au séquençage d’un génome complet. Ces projets peuvent se baser sur des ressources génomiques déjà existantes ou inclure la création de ressources originales.

ERC LUPIN ROOTS : Unravelling cluster root development in white lupin

Plants exhibit a high level of developmental plasticity that is controlled by a complex combination of perception, integration and response. In opposition to animals, where developmental patterns are highly conserved, plant organs are produced as a response to environmental stimuli. Understanding the molecular mechanisms involved in how plants perceive and respond to these stimuli is of key importance and may lead to future application in the agronomic field. One of the most striking developmental adaptations are cluster roots from White Lupin (Lupinus albus)...

Pyramiding strategy for durable resistance to root-knot nematodes in Prunus Rootstocks

Root-knot nematodes (RKN) (Meloidogyne spp.) are extremely polyphagous pests with a high economic impact at the global scale. In stone fruit trees, three major dominant resistance (R) genes, Ma (plum),RMia (peach) and RMja (almond), have been identified and mapped in this objective. Pyramiding all three R genes opens the way to breeding rootstocks protected by at least two of them for a durable resistance...

Analysis of WRKY and ERF genes potentially Involved in salt stress responses in Triticum turgidum L. ssp. durum.

WRKY transcription factors are involved in multiple aspects of plant growth, development and responses to biotic stresses. Although they have been found to play roles in regulating plant responses to environmental stresses, these roles still need to be explored, especially those pertaining to crops. Durum wheat is the second most widely produced cereal in the world. Complex, large and unsequenced genomes, in addition to a lack of genomic resources, hinder the molecular characterization of tolerance mechanisms. This project aims at characterizing TdWRKY genes from durum wheat (Triticum turgidum L. ssp. durum).
