RESUMO

BACKGROUND: In France, special full-time inpatient hospital units (UHSA) have been created for inmates with psychiatric disorders. Since they were established in 2010, the quality of care in such units has not been studied. Particularly, no patient satisfaction survey has been conducted yet. The main objective of this study was to assess the patients' satisfaction about their hospitalization in UHSA. METHODS: A descriptive study has been performed in two hospitals (UHSA of Villejuif and UHSA of Lille-Seclin). From February to May 2015, 125 adult patients were included, at the end of their hospitalization (voluntary or involuntary psychiatric care) in UHSA. The patient's satisfaction was assessed by a psychiatrist who did not participate in patient care with a 16-item scale exploring three areas (quality of care, quality of information provided and UHSA functioning and organization). The items were evaluated with a visual numeric scale (1 to 10). RESULTS: The average score of overall satisfaction was 7.3±1.9 (average±standard deviation) for this sample. For the care area, the average score was 7.6±2; for the quality of information provided, it was 7.5±2.5 and for UHSA functioning and organization, 7.0±2. Furthermore, 84.8 % of patients reported their wish to continue psychiatric care in prison and 77.6 % after release. CONCLUSION: This study demonstrates that patients hospitalized in UHSA are satisfied. Given the relationship between patient satisfaction and compliance, these structures could therefore have an important medical interest for inmates with psychiatric disorders. However, these results need to be replicated in a study involving all the UHSA of France.

RESUMO

One hundred and fifty F(2)-F(3) families from a cross between two inbred sunflower lines FU and PAZ2 were used to map quantitative trait loci (QTL) for resistance to white rot (Sclerotinia sclerotiorum) attacks of terminal buds and capitula, and black stem ( Phoma macdonaldii). A genetic linkage map of 18 linkage groups with 216 molecular markers spanning 1,937 cM was constructed. Disease resistances were measured in field experiments for S. sclerotiorum and under controlled conditions for P. macdonaldii. For resistance to S. sclerotiorum terminal bud attack, seven QTL were identified, each explaining less than 10% of phenotypic variance. For capitulum attack by this parasite, there were four QTL (each explaining up to 20% of variation) and for P. macdonaldii resistance, four QTL were identified, each having effects of up to 16%. The S. sclerotiorum capitulum resistance QTL were compared with those reported previously and it was concluded that resistance to this disease is governed by a considerable number of QTL, located on almost all the sunflower linkage groups.

RESUMO

Downy mildew of sunflower (Helianthus annuus L.), caused by the pathogen Plasmopara halstedii, is a potentially devastating disease. Seventy-seven isolates of P. halstedii collected in twelve countries from four continents were investigated for RAPD polymorphism with 21 primers. The study led to a binary matrix, which was subjected to various complementary analyses. This is the first report on the international genetic diversity of the pathogen. Similarity indices ranged from 89% to 100%. Neither a consensus unweighted pair group method with arithmetic means (UPGMA) tree constructed after bootstrap resampling of markers nor a principal component analysis based on distance matrix revealed very consistent clusterings of the isolates, and groups did not fit race or geographical origins. Phylogenies were probably obscured by limited diversity. Analysis of molecular variance (AMOVA) and Nei's genetic diversity statistics gave similar conclusions. Most of the genetic diversity was attributable to individual differences. The most differentiated races also had the lowest within-diversity indices, which suggest that they appeared recently with strong bottleneck effects. Our analyses suggest that this pathogen is probably homothallic or has an asexual mode of reproduction and that gene flow among countries can occur through commercial exchanges. Knowledge of the downy mildew populations' structure at the international level will help to devise strategies for controlling this potentially devastating disease.

RESUMO

Seed weight and oil content are important properties of cultivated sunflower under complex genetic and environmental control, and associated with morphological and developmental characteristics such as plant height or flowering dates. Using a genetic map with 290 markers for a cross between two inbred sunflower lines and 2 years of observations on F3 families, QTL controlling seed weight, oil content, plant height, plant lodging, flowering dates, maturity dates and delay from flowering to maturity were detected. QTL detected were compared between the F2 and F3 generations and between the 2 years of testing for the F3 families in 1997 and 1999. Some of the QTL controlling seed weight overlapped with those controlling oil content. Several other co-localisations of QTL controlling developmental or morphological characteristics were observed and the relationships between the traits were also shown by correlation analyses. The relationships between all these traits and with resistance to Sclerotinia sclerotiorum and Diaporthe helianthi are discussed.

RESUMO

The resistance of sunflower, Helianthus annuus L., to downy mildew, caused by Plasmopara halstedii, is conferred by major genes denoted by Pl. Using degenerate and specific primers, 16 different resistance gene analogs (RGAs) have been cloned and sequenced. Sequence comparison and Southern-blot analysis distinguished six classes of RGA. Two of these classes correspond to TIR-NBS-LRR sequences while the remaining four classes correspond to the non-TIR-NBS-LRR type of resistance genes. The genetic mapping of these RGAs on two segregating F2 populations showed that the non-TIR-NBS-LRR RGAs are clustered and linked to the Pl5/ Pl8 locus for resistance to downy mildew in sunflower. These and other results indicate that different Pl loci conferring resistance to the same pathogen races may contain different sequences.

RESUMO

Resistance of sunflower to the obligate parasite Plasmopara halstedii is conferred by specific dominant genes, denoted Pl. The Pl6 locus confers resistance to all races of P. halstedii except one, and must contain at least 11 tightly linked genes each giving resistance to different downy mildew races. Specific primers were designed and used to amplify 13 markers covering a genetic distance of about 3 cM centred on the Pl6 locus. Cloning and sequence analysis of these 13 markers indicate that Pl6 contains conserved genes belonging to the TIR-NBS-LRR class of plant resistance genes.

RESUMO

Sclerotinia sclerotiorum and Diaporthe helianthi are important pathogens of sunflower ( Helianthus annuus L.). Two hundred and twenty F2-F3 families were developed from an intraspecific cross between two inbred sunflower lines XRQ and PSC8. Using this segregating population a genetic map of 19 linkage groups with 290 molecular markers covering 2,318 cM was constructed. Disease resistances were measured in field experiments during 3 years (1998, 1999 and 2000) for phomopsis and 2 years for S. sclerotiorum (1997 and 1999). QTL were detected using the interval mapping method at a LOD threshold of 3. A total of 15 QTL for each pathogen resistance were detected across several linkage groups, confirming the polygenic nature of the resistances. These QTL explained from 7 to 41% of the phenotypic variability. The QTL for phomopsis resistance, in the 3 years of tests, mapped in the same region, and this was also true for some forms of S. sclerotiorum resistance in the 2 years of tests. On linkage group 8, QTL affecting resistance to both S. sclerotiorum and D. helianthi mycelium extension on leaves colocalised, suggesting a common component in the mechanism of resistance for these two pathogens. The colocalisation of QTL and breeding for resistance to S. sclerotiorum and to D. helianthi by pyramiding QTL in sunflower are discussed.

RESUMO

The obligate parasitic fungus-like organism Plasmopara halstedii (Farl.) Berl. et De Toni, is the causal agent of downy mildew disease in sunflower (Helianthus annuus). New races of this economically important parasite are regularly detected throughout the world. In addition, fungicide-resistant isolates have been reported in Europe and North America. These observations of parasite evolution, as well as the risk of propagation of the disease by infected seeds, means that it is necessary to guarantee the absence of Plasmopara halstedii in seed shipments. We report here the development of a rapid assay that can be used to detect infection by Plasmopara halstedii in plant tissues. Based on the nucleotide sequence information obtained from one cloned random amplified polymorphic DNA fragment, specific oligonucleotides were designed and used as primers for in vitro DNA amplification by polymerase chain reaction. An amplification product was detected on agarose gel stained with ethidium bromide when DNA from various Plasmopara halstedii races was tested, whereas no amplified DNA was detected when DNA from other origins was tested, including DNA from the host plant. The sensitivity of the technique was evaluated. The assay successfully reveals the presence of Plasmopara halstedii in infected sunflower plants prior to sporulation.

RESUMO

The establishment of a plant-pathogen interaction involves changes in gene expressions in both organisms. To isolate Helianthus annuus genes whose expression is induced during processes of resistance to Plasmopara halstedii, a comparison of the expression pattern of healthy sunflowers was made with sunflowers infected with 2 races of P. halstedii, either virulent or avirulent, using differential display of mRNA. A full-length cDNA, HaAC1, representing a sunflower gene whose expression is enhanced during early stages of the incompatible interaction, was isolated. Different timing of RNA accumulation is observed between compatible and incompatible combinations. Sequence analysis and database search revealed significant homology with auxin-induced genes from plants. The expression of this gene, is also induced after treatment with 2,4-dichlorophenoxyacetic acid (2,4-D), salicylic acid (SA) and wounding.

RESUMO

A candidate-gene approach to analyse the resistance of plants to phytopathogenic fungi is presented. The resistance of sunflower (Helianthus annuus L.) to downy mildew (Plasmopara halstedii) shows a gene-for-gene interaction (monogenic resistance), whereas resistance to white rot (Sclerotinia sclerotiorum) is quantitative, with different levels of resistance for different plant parts. By homology cloning, probes were obtained homologous to some plant resistance genes (nucleotide binding site-like, NBS, genes and serine-threonine protein kinase-like, PK, genes). These clones were used as probes for linkage mapping of the corresponding genes. It was demonstrated that at least three NBS-like loci are located on linkage-group 1, in the region where downy mildew resistance loci have been described. Quantitative trait loci for S. sclerotiorum resistance to penetration or extension of the mycelium in different tissues were studied in three crosses. Major QTLs for resistance were found on linkage group 1, with up to 50% of the phenotypic variability explained by peaks at the map position of the PK locus, 25 cM from the downy mildew loci.

RESUMO

The Pl1 locus in sunflower, Helianthus annuus L., conferring resistance to downy mildew, Plasmopara halstedii, race 1 has been located in linkage group 1 of the consensus RFLP map of the cultivated sunflower. Bulked segregant analyses were used on 135 plants of an F2 progeny from a cross between a downy mildew susceptible line, GH, and RHA266, a line carrying Pl1. Two RFLP markers and one RAPD marker linked to the Pl1 locus have been identified. The RFLP markers are located at 5.6 cM and 7.1 cM on either side of Pl1. The RAPD marker is situated at 43.7 cM from Pl1. The significance and applications of these markers in sunflower breeding are discussed.
