Full textRoot-knot nematodes (Meloidogyne spp. ) are telluric plant parasites with a broad host range that limits the use of crop rotation as control strategy. Chemicals are also restricted in practical agriculture due to their toxicity for human health. Besides the roots Meloidogyne species infest and induce galls on the surf ace and necrotic spots in the fesh of tubers of the potato, Solanum tuberosum. Infested tubers are unacceptable for both processing and fresh market and they are putative sources of dissemintatin of these parasites. Genetic resistance is the favoured control strategy in nematode management because it is usually effective and has no deleterious effects on environment but, no resistant potato cultivar is yet available. For breeding purpose, the resistances of two accessionsof nematodes species Meloidogyne incognita, M. Arenaria and M. Javanica and the temperate species M. Fallax have been investigated. Our objectives were to : 1° understand the species M. Fallax have been investigated. Our objectives were to: 1) understand the effects on the feeding and the development of the juveniles, genetic determinism of the resistances); 2) map major gene (s) or quantitative trait loci (QTL) that control the resistance. Compared to susceptible potato plants, both resistant accessions were significantly less infected. This was due to delayed and then arrested penetration of the juveniles in the roots. The accession harbouring the resistance to M. Fallax developed a necrotic reaction at the feeding site of the juveniles and prevented their development to the female stage. A “F1” diploid progeny was obtained using a dihaploid susceptible potato genotype as the female juveniles suggesting a monogenic control of the resistance. However, “necrotic” and “non necrotic” hybrid genetoypes showed a continuous distribution when considering the nematode females developed in their roots

Full textIn potato plant, Solanum tuberosum, the phytopathogens Pectobacterium and Dickeya are responsible for blackleg and soft rot diseases causing extensive damage in fields and also during storage of tubers. Apart from prophylaxis methods, no treatment permits to control these diseases. The FN3PT / inov3PT is carrying out various research projects in order to better understand these pathogens and to offer suitable treatments. The objective of this work was to study the genes essential to the bacterium D. solani RNS 08.23.3.1A during the different stages of the infectious cycle, namely the colonization of the rhizosphere, the maceration of the stems and the maceration of the tubers. For this, a Tn-seq approach was used, the robustness of which was evaluated by determining the essential genome of D. solani. The genes essential to the various conditions in vivo were then identified. Secondly, a screening of biostimulating molecules of the biocontrol agent Pseudomonas spp PA14H7 was carried out. This screening made it possible to identify different molecules metabolized by PA14H7. Greenhouse biostimulation tests were performed to validate the biostimulatory effect of these molecules on a population of biocontrol agents artificially introduced into the potato rhizosphere. The incidence on the disease has been observed. Then the antibiosis action of 6 previously identified biocontrol agents was evaluated in vitro against a panel of 41 pathogens of Pectobacterium and Dickeya
