Sclerotinia sclerotiorum : phytotoxins and metabolism of phytoalexins
Sclerotinia sclerotiorum (Lib.) de Bary is a plant pathogenic fungus causing serious yield losses in a broad range of cultivated plants, excluding cereals. Most of the economically important brassicas such as canola, rapeseed, mustards, cabbages and others such as sunflower, peanut, bean, soybean, …

Seleção de isolados de Trichoderma spp. antagonistas a Sclerotinia sclerotiorum
… em Minas Gerais e avaliar o antagonismo a S. sclerotiorum, agente causal do mofo-branco de ambas as culturas. Obtiveram-se 48 isolados, sendo 30 da rizosfera, 11 epifíticos, quatro endofíticos e três de restos culturais. Com base no sequenciamento das regiões ITS, TEF1-α e RPB2, incluíram-se …

Population Structure, Aggressiveness, and Molecular Genetic Variability of Sclerotinia Sclerotiorum
… and molecular genetic variability of Sclerotinia sclerotiorum (Lib) de Bary was investigated. Population structure was determined by mycelial compatibility grouping (MCG). MCG and aggressiveness of S. sclerotiorum isolates from diverse hosts and geographic locations, from soybean …

Genetic Analysis of the Resistance of Soybean Genotypes to Sclerotinia Sclerotiorum
… germplasm to identify new genetic sources of sclerotinia stem rot resistance; (ii) determine the inheritance of field resistance to sclerotinia stem rot in a cross between the partially resistant cultivars Asgrow 'A2506' (A2506) and Novartis 'S19--90' (S19--90); (iii) determine the inheritance …

Transcriptomic characterization of soybean – sclerotinia sclerotiorum interaction at early infection stages
Sclerotinia stem rot, also referred to as white mold, poses a threat to soybean production world-wide. The causal agent, Sclerotinia sclerotiorum (Lib.) de Bary, can survive in harsh environments and has an extremely broad host range. No naturally complete resistance has been reported to exist in …

Diversity, characteristics and potential for biological control of Sclerotinia sclerotiorum mycoviruses in New Zealand
… of controlling plant pathogenic fungi, such as Sclerotinia sclerotiorum, that avoid the drawbacks associated with fungicide-based control, such as resistance and environmental impact. Mycoviruses have been used to reduce the virulence of fungal pathogens, such as using hypoviruses to control the …

Integrated management of stalk rot disease (Sclerotinia sclerotiorum) of cauliflower in the eastern hills of Nepal
… Previous work indicated that stalk rot (Sclerotinia sclerotiorum) is an important disease of cauliflower. Currently, no single management technique provides a satisfactory level of control of stalk rot disease; therefore the management of stalk rot had to be approached in several ways in …

Controle biológico de isolados de Sclerotinia sclerotiorum por Trichoderma spp. e Ulocladium atrum e patogenicidade ao feijoeiro (Phaseolus vulgaris L.)
… a cultura do feijão, o mofo branco causado por Sclerotinia sclerotiorum é uma das mais importantes, principalmente em sistemas de cultivo que adotam a agricultura irrigada. Quatro isolados de Sclerotinia sclerotiorum, sendo três provenientes de plantas cultivadas com sintomas do mofo branco …

Qualidade fisiológica de sementes de algodoeiro e comportamento in vitro de Sclerotinia sclerotiorum (Lib.) De Bary, submetido a diferentes temperaturas
… of diseases such as white mold, caused by Sclerotinia sclerotiorum, is responsible for causing symptoms such as wilting, necrosis and wet rot in the stems. This study aimed to evaluate the effect of temperature on mycelial growth and sclerotia production, identify the incidence of pathogens …

Functional analysis of soybean dirigent genes
… reduction in the size of lesions induced by Sclerotinia sclerotiorum when the soybean dirigent-like genes were transiently expressed in N. benthamiana.

Cluster analysis of soybean pathogen-responsive genes and functional characterization in Arabidopsis
… For other diseases, like white mold caused by Sclerotinia sclerotiorum and sudden death syndrome (SDS) caused by Fusarium virguliforme, defense requires several genes, and therefore defense is controlled by quantitative trait loci (QTL). To understand plant defense and the genes involved, …

Host and pathogen genomics: the molecular repertoire of soybean and Sclerotinia interactions
Sclerotinia sclerotiorum (Lib.) de Bary is an economically important soybean pathogen in the U.S. and worldwide. Understanding the disease caused by this fungus can help in controlling it. In the present study, genome-wide screenings were carried out to identify soybean mRNAs and small RNAs that …

Identification and characterization of genes in antagonism against soybean fungal pathogens by lysobacter enzymogenes
… hyphae growth of the white mold pathogen (Sclerotinia sclerotiorum). Among them, 74 mutants no longer inhibited S. sclerotiorum hyphae growth. The insertion sites for 50 out of these 74 mutants were determined by inverse or RATE PCR and sequencing. Nine mutants were selected for further …

Evaluation of Lysobacter enzymogenes C3 for control of soybean fungal diseases
… Rhizoctonia solani, Septoria glycines, and Sclerotinia sclerotiorum. Our experiments confirmed previous reports that antagonism arises from a broad spectrum of inhibition activities. Next, we evaluated LeC3 as a biological control agent on soybean hosts. We first used a test tube assay to …

Estudio del extracto de propóleos y del aceite esencial de orégano para el control de fitopatógenos de importancia en la producción hortícola
… y forma de actuar frente a Penicillium allii y a Sclerotinia sclerotiorum. El hallazgo más novedoso de estos estudios fue que la combinación de EP con AEO tuvo un efecto antifúngico sinérgico frente a los mencionados patógenos. Por otro lado, también se probó la acción antibacteriana del EP sobre …
