Potato cyst nematodes induce changes in plant host gene expression following root invasion. For an accurate comparison of gene expression by reverse transcription quantitative real-time PCR (RT-qPCR), internal reference genes are necessary for transcript normalization. Very few experimental data on suitable reference genes are available for...

With the banning of most chemical nematicides, the control of root knot nematodes (RKNs) in vegetable crops is mainly based on the deployment of single-major resistance genes (R-genes). However, these genes are rare and their efficiency is threatened by RKNs capacities of adaptation. ln pepper, several dominant R-genes are efficient against...

With the banning of most chemical nematicides, the control of root-knot nematodes (RKNs) in vegetable crops is now based essentially on the deployment of single, major resistance genes (R-genes). However, these genes are rare and their efficacy is threatened by the capacity of RKNs to adapt. In pepper, several dominant R-genes are effective...

Volatile organic compounds (VOCs) are of first importance in plant defenses since they alter host-plant location by herbivore insects. The worldwide distribution of tomato offers to explore the ecological diversity of defensive VOCs produced by plants supporting a large range of local adaptations. In this study, first, we analyzed the diversity...

Potato cyst nematodes induce changes in gene expression after infecting the roots. For studying gene expression, reverse transcription quantitative real-time PCR (RT-qPCR) is now a standard method. However, for accurate quantication of transcripts, a set of internal control genes, stable under different experimental conditions, is necessary for...

Since volatile organic compounds (VOCs) shape plant defenses against pests, ecologists strive to understand their sources of variation. The worldwide distribution of tomato offers an ideal system to explore the ecological diversity of VOCs produced by plants supporting a large range of local adaptations. In this study, we analyzed the diversity...

Débuté en 2021, le projet Cap Zéro Phyto financé par le PPR « Cultiver et protéger autrement » a pour objectif d'étudier indépendamment cinq leviers immunitaires et leurs combinaisons pour protéger notamment les cultures de tomate contre leurs principaux bioagresseurs (la mouche Tuta absoluta, le champignon responsable de la pourriture grise...
