RésiLens: A research project aiming at identifying bruchid and root rot resistance sources in lentil (Lens culinaris)
National audience; Introducing legumes in modern cropping systems increases crop diversity and reduces the use of external inputs. It thus contributes to achieving sustainable food and feed production. Lentil (Lens culinaris Medik.) is an environmentally friendly, nutritious, protein-rich legume food crop. It is grown in a wide range of climatic conditions and fixes atmospheric nitrogen through bacterial symbiosis. In France, lentil cultivated areas are continuously increasing but are still largely inferior to the areas cultivated with cereals or other legumes such as pea and faba bean. One of the most serious problems for lentil cultivation is due to the insect pests known as seed beetles …
Two genomes of highly polyphagous lepidopteran pests (Spodoptera frugiperda, Noctuidae) with different host-plant ranges
International audience; Emergence of polyphagous herbivorous insects entails significant adaptation to recognize, detoxify and digest a variety of host-plants. Despite of its biological and practical importance - since insects eat 20% of crops - no exhaustive analysis of gene repertoires required for adaptations in generalist insect herbivores has previously been performed. The noctuid moth Spodoptera frugiperda ranks as one of the world’s worst agricultural pests. This insect is polyphagous while the majority of other lepidopteran herbivores are specialist. It consists of two morphologically indistinguishable strains (“C” and “R”) that have different host plant ranges. To describe the evol…
