Legumes adapt their root architecture to environmental conditions by modifying the growth and number of their lateral roots, but also by developing nitrogen-fixing nodules in nitrogen-deficient conditions and in the presence of symbiotic bacteria (rhizobia). Systemic regulatory pathways involving signaling peptides perceived by receptors kinase allow the coordination of the development of these root organs according to the availability of nitrogen in the soil and the needs of the plant. The objectives of this thesis were, on the one hand, to identify which peptide signal acts via one of these receptors, namely CRA2, to induce nodulation and suppress the formation of lateral roots; and secondly to determine how this pathway integrates with o...
