La grosse altise représente une menace de plus en plus préoccupante pour les cultures de colza d'hiver en Europe, accentuée par la baisse d'efficacité des traitements chimiques à base de pyréthrinoides et des restrictions réglementaires. Le projet RESALT vise à identifier et introgresser des résistances génétiques dans des variétés élites de colza,...

Pea (Pisum sativum), a crop historically significant in the field of genetics, is regaining momentum in sustainable agriculture due to its high protein content and environmental benefits. However, its cultivation faces significant challenges from root rot, a complex disease caused by multiple soil-borne pathogens prevalent across most pea growing r...
Phytophthora infestans remains a major threat to global potato production. This study focused on characterizing and assessing the pathogenicity of P. infestans isolates on detached potato leaves and in greenhouse trials across four cultivars. Seven isolates were obtained from high potato-producing regions in the department of Nariño, Colombia. The ...
Les Brassica regroupent des espèces cultivées courantes, comme le navet (B. rapa), le choux (B. oleracea) ou encore le colza (B. napus). Leur domestication a grandement accompagné celle de leurs bioagresseurs, qui court-circuitent régulièrement les mécanismes de défense des plantes. Pour autant, le système immunitaire des plantes n’est pas en manqu...
Wheat rusts, including leaf, stripe, and stem rust, have been a threat to global food security due to their devastating impact on wheat yields. In recent years, significant strides have been made in understanding wheat rusts, focusing on disease spread mechanisms, the discovery of new host resistance genes, and the molecular basis of rust pathogene...
Bananas, a staple food globally and a key agricultural commodity, face a severe threat from the fungus Fusarium oxysporum f. sp. cubense (Foc), significantly impacting production. Genetic improvement to develop resistant cultivars stands out as a crucial strategy to mitigate this disease. This study focused on assessing and recommending enhanced di...

Root exudates play a key role in the life cycle of Verticillium dahliae, the causal agent of Verticillium wilt diseases, because they induce microsclerotia germination to initiate plant infection through the roots. In olive plants, the genotype and the application of biological control agents (BCAs) or phosphonate salts influence the ability of roo...
Bananas are a staple food that considerably contributes to both food security and income generation, especially in countries of Africa, Asia, and Central and South America. The banana plant (Musa spp.) is affected by various pathogens, of main concern being the plant-parasitic nematodes associated with the rhizosphere, the most important of which a...
Le projet RESALT fédère un consortium comprenant des partenaires académiques (INRAE) et privés (Terres Inovia, Innolea et 10 obtenteurs). Durée: 36 mois (11/2022 - 10/2025). Les objectifs de RESALT sont de :1. développer des méthodes fiables de détection de résistance.2. cribler un panel de diversité à la recherche de sources de résistance.3. compr...
The tomato is one of the most important vegetable crops grown worldwide. Tomato brown rugose fruit virus (ToBRFV), a seed-borne tobamovirus, poses a serious threat to tomato production due to its ability to break the resistant genes (Tm-1, Tm-2, Tm-22) in tomatoes. The objective of this work was to identify new resistant source(s) of tomato germpla...
