1. Combining Ability for Resistance to White Mold in a Diallel Cross of Soybean
Abstract The white mold, caused by Sclerotinia sclerotiorum (Lib.) de Bary, is one of the most important diseases of soybean. The objective of the present work was to evaluate the soybean reaction to the fungus S. sclerotiorum, which causes white mold, in a partial diallel with 50 crosses. The Group I of parents was composed of ten experimental lines with hi

3. Chemical constituents of essential oil from Murraya paniculata leaves and its application to in vitro biological control of the fungus Sclerotinia sclerotiorum
ABSTRACT Besides their value as therapeutic resources, medicinal plants may also be used as sources of active ingredients against phytopathogens. Fungi can grow and cause spoilage in food, thus, resusting in decrease in its quality and quantity. This research aimed at evaluating the effect of essential oil from Murraya paniculata (ML-EO) leaves on mycelial

4. Reaction of sources of resistance to white mold to microsatellite haplotypes of Sclerotinia sclerotiorum
ABSTRACT White mold caused by the fungus Sclerotinia sclerotiorum is the most yield-limiting disease of common bean in Brazil. To date, there has been no commercial cultivar resistant to this disease. In a greenhouse we evaluated white mold resistance sources (Cornell 605, A195 and G122) against eight isolates of S. sclerotiorum from five Brazilian states. A

5. Potential of soil fumigation with mustard essential oil to substitute biofumigation by cruciferous plant species
Soil fumigation with the synthetic essential oil of mustard (93% allyl isothiocyanate) (EOM) was evaluated as a substitute of bio-fumigation with cruciferous plant species, using Sclerotium rolfsii and Sclerotinia sclerotiorum as test pathogens, together with its non-target effect on the general population of soil microorganisms. The mortality of the sclerot

6. PROGRAMAÇÃO GENÉTICA, REDES NEURAIS ARTIFICIAIS E TÉCNICAS DE BALANCEAMENTO NA MODELAGEM DE DADOS AGRÍCOLAS: ESTUDO DA DOENÇA MOFO BRANCO
Data regression problems are common in the literature, therein it is desired to infer the relationship between the dependent (output) and independent variable (input) from a dataset. Infer the relationship between variables is not a simple task, many times there is a high non-linearity and noise in the data inside them. Two machine learning techniques that a

7. Análise da diversidade genética em populações de Sclerotinia sclerotiorum / Analysis of genetic diversity in populations of Sclerotinia sclerotiorum
O fungo Sclerotinia sclerotiorum está entre os fitopatógenos mais bem sucedidos, onívoros e sem hospedeiros definido, é considerado um dos patógenos fúngicos mais importantes no mundo. Está distribuído em todas as regiões produtoras, sejam elas temperadas, subtropicais ou tropicais. O fungo produz estruturas de resistência denominadas escleródios,

8. Technical parameters for the white mold control using air- assisted hydraulic sprayer / Parâmetros técnicos para o controle do mofo-branco na cultura do feijão utilizando pulverizador hidráulico de barra com assistência de ar
The white mold, caused by the fungus Sclerotinia sclerotiorum, is one of the most destructive diseases of the bean plant in the world, especially in crops under conditions of mild temperatures and high soil and air humidity. In general, primary infections caused by this fungus start due to the presence of free water and an exogenous energy source, usually se

9. Manejo da podridão de Sclerotinia (Sclerotinia sclerotiorum) e Míldio (Bremia lactucae) na cultura de alface
Lettuce is the highest consumed vegetable in Brazil. It can however be severely affected by the fungus Sclerotinia sclerotiorum, Sclerotinia minor and Bremia lactucae; diseases considered to be ground and aerial part, respectively. The objective of this experiment was to evaluate the effect of different mulches, fungicides and one foliar fertilizer on the in

10. Production of Cell Wall-Degrading Enzymes by the Phytopathogenic Fungus Sclerotinia sclerotiorum
The range of polysaccharide-degrading enzymes and glycosidases formed by the phytopathogenic fungus Sclerotinia sclerotiorum was monitored following growth on 16 carbohydrate substrates. Endo- and exoenzymes capable of degrading cellulosic, hemicellulosic, and pectinolytic polysaccharides were secreted. Pectinolytic activities were produced constitutively on

11. Oxalic Acid, a Pathogenicity Factor for Sclerotinia sclerotiorum, Suppresses the Oxidative Burst of the Host Plant
Effective pathogenesis by the fungus Sclerotinia sclerotiorum requires the secretion of oxalic acid. Studies were conducted to determine whether oxalate aids pathogen compatibility by modulating the oxidative burst of the host plant. Inoculation of tobacco leaves with an oxalate-deficient nonpathogenic mutant of S. sclerotiorum induced measurable oxidant bio

12. Oxalate Production by Sclerotinia sclerotiorum Deregulates Guard Cells during Infection1[w]
Oxalic acid is a virulence factor of several phytopathogenic fungi, including Sclerotinia sclerotiorum (Lib.) de Bary, but the detailed mechanisms by which oxalic acid affects host cells and tissues are not understood. We tested the hypothesis that oxalate induces foliar wilting during fungal infection by manipulating guard cells. Unlike uninfected leaves, s
