LATE blight of potato ,CYST nematodes ,POTATOES ,ARACHNOID cysts ,POTATO virus Y ,GLOBODERA pallida ,INTEGRATED pest control - Abstract
Each season, crops face simultaneous or successive multiple infections. Yet cultivar resistance is often bred against one pest at a time, and screened under single infections. This raises the question of resistance expression bred under mono‐infections when exposed to multiple infections. We tackled this question by measuring the level of quantitative resistance of potato cultivars to either Globodera pallida or Phytophthora infestans under single or multiple infections, using potato virus Y (PVY) or Rhizoctonia solani as the co‐infector. Overall, co‐infection resulted in less multiplication of the target pathogen compared to single infection, although this reduction did not always reach statistical significance. A preliminary assessment of defence gene expression in plants infected with P. infestans alone or together with PVY or R. solani suggested that P. infestans repressed defence genes previously triggered by PVY, but boosted the expression of these genes when primed by R. solani. Together, these data support the view that resistance expression is impacted by co‐infection, and that it should be screened under multiple infection situations to be best assessed and exploited as a component of Integrated Pest Management strategies.

International audience; The effect of pesticides on public health and the decline of biodiversity are alarming. Alternative methods to control plant diseases are urgently needed. We are faced with a major scientific challenge, which requires strong theoretical bases. Host mixtures are a promising component of future agro-ecological solutions but their design remains to be optimized. In plant disease epidemiology, whether and how host mixtures may reduce disease prevalence has long been studied, both the-oretically and empirically. In particular, it is well known that pathogen diversityand plant immunity are key to the success of host mixtures against plant diseases. This is because pathogen genotypes that produce little or no symptoms on some plant genotypes trigger a long-lasting immune response protecting against subsequent infections from other pathogen genotypes; this is a form of cross immunity. However, this phenomenon was thus far absent from mathematical models aiming at designing host mixtures. In this study, we explored under which circumstances two pathogen genotypes can coexist in a mixture composed of two host genotypes, and how this affects the total prevalence of the disease. In addition, we assessed the ecological and epidemiological implications of cross immunity triggered byone pathogen genotype on one host genotype. We showed that there is an optimal fraction of each host genotype to be achieved to minimize disease prevalence. The existence of such an optimal fraction is a direct consequence of cross immunity. The stronger the host immune response, the stronger the reduction in disease prevalence brought by host mixtures. Our results highlight the importance of considering both pathogen diversity and plant immunity in designing optimal host mixtures. Future research in behavioral epidemiology may help achieving optimal mixtures in the field.

- Abstract
[ES] La sarna del manzano es una enfermedad comercialmente importante. Para poder controlar esta enfermedad, se utiliza una gran cantidad de fungicidas en los campos de cultivo. La opinión pública está preocupada por el uso de fungicidas y su efecto en la salud humana y el medio ambiente. Además, de otros métodos de control, los inductores de defensa de la planta pueden ser una alternativa para reducir el uso de fungicidas; particularmente Acibenzolar-S-Methyl (ingrediente activo del producto Bion). Sin embargo, no se ha realizado ningún estudio para ver los efectos de ASM en una amplia gama de cepas y si el uso repetido de ASM resulta en la selección de cepas que son menos sensibles a ASM. Para responder a esta pregunta de manejo sostenible, se realizaron experimentos en condiciones controladas sobre 94 cepas de Venturia inaequalis: 34 de huertos no tratados, 30 cepas de un huerto con Manejo Integrado de Plagas (IPM) y 30 cepas de un huerto con tratamientos de IPM y ASM ligeros. Cada cepa se inoculó en 8 plantas tratadas con ASM y 8 plantas tratadas con agua. La severidad de la enfermedad se observó en cada planta de 7 a 16 días después de la inoculación. Se encontró una amplia gama de variación de la gravedad de la enfermedad, es decir, la agresividad de las cepas. ASM fue eficaz para la mayoría de las cepas. Sin embargo, la eficiencia de ASM fue muy variable dependiendo de la cepa, y algunas cepas mostraron un efecto no significativo de ASM. La mayoría de estas cepas fueron muestreadas de huertos no tratados con ASM, solo una cepa fue muestreada del huerto tratado con ASM. Este resultado sugiere que a pesar de la existencia de cepas que tienen una baja sensibilidad a ASM, estas cepas no se seleccionaron mediante el uso repetido de ASM en un huerto manejado en IPM ligero. Se necesitan más estudios y datos para comprender este proceso., [EN] Apple scab is a commercially important disease and to control this disease a large amount of fungicides is used in orchards. People are now concern against fungicide use and its effect on human health and environment. In addition to other control methods, plant defense inducers may be a solution for reducing fungicide use; particularly Acibenzolar-S-Methyl (active ingredient of Bion product). However, no study has been done to see effects of ASM to a vast range of strains and if repeated use of ASM results in selection of strains that are less sensitive to ASM. To answer this question of sustainability experiments were conducted in controlled condition on 94 strains of Venturia inaequalis: 34 from untreated orchards, 30 strains from an orchard with light Integrated Pest Management (IPM) and 30 strains from an orchard with light IPM and ASM treatments. Each strain was inoculated on 8 ASM and 8 water- treated plants. Disease severity was observed on each plant from 7 to 16 days after inoculation. Wide range of variation of disease severity in other words aggressiveness of strains was found. ASM was effective to most of the strains. However, the efficiency of ASM was very variable depending of the strain, and a few strains showed non-significant effect of ASM. Most of them were sampled from non ASM treated orchards, only one strain was sampled from ASM treated orchard. This result suggests that despite the existence of strains that have a low sensitivity to ASM, these strains were not selected by repeated use of ASM in an orchard managed in light IPM. More study and data are needed to understand this process.

SummaryPathogen recognition by plants via pathogen-associated molecular patterns leads to PAMP-triggered immunity. However, pathogens can modulate it via the secretion of effectors. We hypothesize that in potato, induced defense triggered by a Phytophthora infestans concentrated culture filtrate (CCF) could alter both effector expression and disease severity.CCF was sprayed onto three potato genotypes with different resistance levels, before inoculation with P. infestans. Symptoms were scored visually at 1-4 dpi, while the expression of defense and effector genes was assessed by qRT-PCR.CCF induced most defense genes in Désirée (PRs, EIN3) and Bintje (PRs, PAL and POX), but repressed most defense genes in Rosafolia. On the contrary, CCF induced most effector genes in Rosafolia (Pi03192, Avrblb2, Avr3a, EPIC2B and SNE1). INF1 was over-expressed in Bintje, despite its earlier expression in both Désirée and Rosafolia compared to unsprayed controls. Pi03192 was repressed in Désirée, and was expressed earlier in Rosafolia than in controls. However, induced defense responses by CCF significantly reduced lesion areas at 3 dpi only in Désirée.The effectiveness of induced defense thus depends on host genotypes. It results from differential interactions and kinetics of defense and effector genes expressions.

International audience; Many plant parasites interact with their host through gene-for-gene interactions. Considerable polymorphism for virulence (defined as the ability to overcome a resistance gene) and resistance occurs in agricultural and wild ecosystems. Fitness costs of resistance and virulence are required for polymorphism to be maintained in the long run. A previous study showed that there exist virulence costs in the Great Famine pathogen (Phytophthora infestans). These costs are mainly due to a lower spore production. However, virulent genotypes have a shorter latent period (time-to-sporulation). The latter observation is intriguing as virulent genotypes are expected to benefit from shorter latent periods. A key component of plant immunity is termed systemic acquired resistance (SAR): this is a partial resistance response that occurs following an earlier exposure to a pathogen. Through an adaptive dynamics approach, we show that SAR, by increasing the latent period of subsequent infections, may indeed select for shorter latent period in virulent genotypes. This way, we provide an original and possibly testable hypothesis to explain previously puzzling observations.

International audience; Lipopolysaccharides (LPS) are a component of the outer cell surface of almost all Gram-negative bacteria and play an essential role for bacterial growth and survival. Lipopolysaccharides represent typical microbe-associated molecular pattern (MAMP) molecules and have been reported to induce defense-related responses, including the expression of defense genes and the suppression of the hypersensitive response in plants. However, depending on their origin and the challenged plant, LPS were shown to have complex and different roles. In this study we showed that LPS from plant pathogens Pectobacterium atrosepticum and Pectobacterium carotovorum subsp. carotovorum induce common and different responses in A. thaliana cells when compared to those induced by LPS from non-phytopathogens Escherichia coli and Pseudomonas aeruginosa. Among common responses to both types of LPS are the transcription of defense genes and their ability to limit of cell death induced by Pectobacterium carotovorum subsp carotovorum. However, the differential kinetics and amplitude in reactive oxygen species (ROS) generation seemed to regulate defense gene transcription and be determinant to induce programmed cell death in response to LPS from the plant pathogenic Pectobacterium. These data suggest that different signaling pathways could be activated by LPS in A. thaliana cells.

International audience; Staphyloccocus aureus is reported to be one of the most frequent pathogens involved in food-borne diseases associated with dairy products, especially with raw milk cheese. Some strains produce enterotoxins as Staphylococcal enterotoxin A (SEA) which is involved in 75% of food poisoning outbreaks. Actually few methods are both sensitive and specific enough for confirming the diagnosis of staphylococcal food poisoning. In this work, an Enzyme-Linked ImmunoSorbent Assay (ELISA) was set up and optimised to detect SEA in milk and cheese. Various anti-SEA antibodies: polyclonal sera, anti-peptide polyclonal sera and monoclonal antibodies, used for the capture and or detection steps were compared and analysed. The mouse anti-whole SEA polyclonal serum, used as detection detected 32 pg/ml SEA in buffer and 64 pg/ml in milk. These concentrations were well under the limit set for food safety. This assay was also highly specific of SEA and no cross-reaction was observed with the other staphylococcal enterotoxins. In contaminated cheese samples the time of enterotoxin extraction was reduced by using ultrafiltration method instead of dialysis and the detection limits were 1.5-2.5 and 1.9-3 times more sensitive than a commercial kit and the official method, respectively. Preliminary study of SEA detection with the piezoelectric immunosensor allowed detecting and quantifying SEA within 10 min in unprocessed food but the sensitivity was not sufficient. The ELISA assay with mouse antibodies is likely suitable for SEA routine detection not only in dairy product but also in various foods as sauce and liver mousse. (C) 2012 Elsevier Ltd.

International audience; Pectobacterium carotovorum subsp. carotovorum, Pectobacterium astrosepticum and Pectobacterium chrysanthemi are the soft rot tuber of potatoes pathogens (Solanum tuberosum). The aim of this study was to determine the occurrence of these pathogens in Moroccan regions producing potatoes. Fifty three isolates of Pectobacterium were isolated on medium Crystal Violet Pectate. The comparison of their bacteriological characteristics with standard strains allowed us to conclude that all the isolates belonged to the Pectobacterium. With regard to phenotype characteristics, the variability that was found included 32 typical Pectobacetrium carotovorum subsp. carotovorum, 3 typical Pectobacterium atrosepticum, and 18 atypical Pectobacterium carotovorum subsp. carotovorum. Three strains of the atypical group; showed that the biochemical properties overlap among the Pectobacterium carotovorum and Pectobacterium chrysanthemi. These data were needed molecular characterization. However, the PCR amplification of total genomic DNA of 53 isolates with the two primers Y1/Y2 and P143/P145 yielded an amplified fragment of the expected size (434 bp) only with Y1/Y2, indicated that all the isolates collected and tested belonged to the Pectobacterium carotovorum species. On the basis the pathogenicity tests, these strains revealed that they were pectinolytic, and showed differences in aggressiveness against potato and leaves of tobacco
