Genetic diversity of nodulated root structure and nitrogen nutrition in a core collection of pea
2013
Pea (Pisum sativum) is the third most important grain legume worldwide, and the increasing demand for protein-rich raw material for animal feed or human nutrition has led to a greater interest in this crop as a protein source. Moreover, legumes do not need nitrogen (N) fertilizers, thanks to their natural ability to use, as main N resource, the atmospheric N2 from symbiosis in nodules with Rhizobiaceae spp. However, N nutrition can still be a limiting factor of yield and seed quality in legumes because nodules are very sensitive to their local environment, in particular to nitrate, and root systems of N2 fixing legumes are poorly developed, which makes them unable to explore a large soil vo…
Comparative genome-wide-association mapping identifies common loci controlling root system architecture and resistance to Aphanomyces euteiches in pea
2017
BAP GEAPSI INRA; International audience; Plant architecture can contribute to decrease plant susceptibility to pathogens by favoring mechanisms leading to infection escape or increased tolerance. Combining genetic resistance with architectural traits that can negatively impact disease development is thus a strategy of great interest to reduce epidemics. Until now, most strategies exploiting plant architecture have focused on the aerial parts of plants. Few studies have been done on the identification of root system architecture (RSA) traits limiting root disease development and even less on their use in breeding. Aphanomyces euteiches, a soil-borne pathogen infecting roots, is a major limit…
