WP Leader: Alain Bouchereau (INRA – IGEPP)
Partners involved: INRA-IGEPP, INRA-EVA, INRA-EcoSys (ex-EGC), INRA-Agronomie, IJPB, TERE, Biogemma, Terres inovia (ex-Cetiom) and Syngenta Seeds
Objectives:
WP2 objectives are to decipher functional traits involved in winter OSR nitrogen use efficiency (NUE), to search for genetic variation in physiological and molecular key determinants of high N uptake and/or high N utilization efficiency and to develop/adapt ecophysiological integrative models of plant and canopy production under N constraint. WP2 aims to develop and evaluate original tools and methodologies for convenient phenotyping of plant N status and crop NUE that could facilitate the large phenotyping ambitions of WP3 and WP4.
WP2 will:
1- Decipher the key polymorphic regulating components of trophic resource remobilization from sources to sink tissues and seed lipid deposition.
2- Tackle different connected scientific questions concerning genetic responses to N variability, at different scales (plant and canopy), at different growth periods (vegetative and reproductive), and for various dynamics and intensities of N limitations, with emphasis on ecophysiological models as privileged tools to further help for genotype assessment or fertilization recommendations.
3- Adapt, demonstrate the relevance of existing tools and to develop new methodologies for convenient and rapid monitoring of plant N status and NUE.
Group projects :
T2.2.1 Genetic variability in NUE, LAI dynamics during vegetative growth at plant level (ARNICA)
T2.2.2 Genetic variability in LAI dynamics, NUE and seed set at canopy level (CANOPY)
