Authors: D.A. Souza, M. Balestre, A.K.A. Pamplona, L.R. Pinheiro, F.C. Alves, D.R. Pereira and J.B. Santos
In this study, we aimed to estimate the relationship between some common bean traits using molecular markers and applying QTL mapping. We used a segregating population derived from a crossing between common bean cultivars, Jalo and Small White, in the Southern State of Minas Gerais. Of F2 plants, 190 F2:3 progenies were genera..

Effect of different carbon sources on proteases secreted by the fungal pathogen Sclerotinia sclerotiorum during Phaseolus vulgaris infection
Authors: E.A. Bueno, M.B. Oliveira, R.V. Andrade, M. Lobo Junior and S. Petrofeza
Sclerotinia sclerotiorum (Sclerotiniaceae) is a plant pathogenic fungus that causes white mold disease in vegetable crops, including the common bean (Phaseolus vulgaris). Proteases produced by fungi are normally an important part of the pathogenic process in the host. We examined the effect of different carbon sources - pectin, glucose, and cell wall of P.. Read More»

Purification, characterization, and heterologous expression of an antifungal protein from the endophytic Bacillus subtilis strain Em7 and its activity against Sclerotinia sclerotiorum
Authors: N.N. Wang, X.N. Gao, X. Yan, Z.P. Li, Z.S. Kang, L.L. Huang and Q.M. Han
An antifungal protein exhibiting a high activity against Sclerotinia sclerotiorum in vivo was purified by ammonium sulfate precipitation, hydrophobic chromatography, and gel filtration chromatography from the culture filtrate of the endophytic Bacillus subtilis strain Em7. The protein was characterized as a β-1,3-1,4.. Read More»

Identification of QTLs of resistance to white mold in common bean from multiple markers by using Bayesian analysis
Authors: L.A.C. Lara, J.B. Santos, M. Balestre, I.A. Lima, A.K.A. Pamplona,J.S. Veloso and P.H. Silva
In this study, we identified simple sequence repeat, amplified fragment length polymorphism, and sequence-related amplified polymorphism markers linked to quantitative trait loci (QTLs) for resistance to white mold disease in common bean progenies derived from a cross between lines CNFC 9506 and RP-2, evaluated using the oxalic acid test and usi..

Characterization of the dry bean polygalacturonase-inhibiting protein (PGIP) gene family during Sclerotinia sclerotiorum (Sclerotiniaceae) infection
Authors: M.B. Oliveira1, L.B. Nascimento1, M.L. Junior2 and S. Petrofeza1
Polygalacturonase-inhibiting proteins are leucine-rich repeat proteins that inhibit fungal endopolygalacturonases. The interaction of polygalacturonase-inhibiting protein with endopolygalacturonases limits the destructive potential of endopolygalacturonases and may trigger plant defense responses induced by oligogalacturonides..

Expression and validation of PvPGIP genes for resistance to white mold (Sclerotinia sclerotiorum) in common beans (Phaseolus vulgaris L.)
Authors: R.C.C. Vasconcellos, T.F.C. Lima, C.N. Fernandes-Brum, A. Chalfun-Junior and J.B. Santos
The interaction between polygalacturonase-inhibiting proteins (PGIPs), produced by plants, and endopolygalacturonases (PGs), produced by fungi, limits the destructive potential of PGs and can trigger plant defense responses. This study aimed to i) investigate variation in the expression of different common bean (Phaseolus vulgaris L.) genotypes and its re.. Read More»

Genetic control of the resistance of common beans to white mold using the reaction to oxalic acid
Authors: R.P. Antonio, J.B. Santos, T.P. Souza and F.F. Carneiro
The use of genetically resistant cultivars is the best method to reduce losses caused by white mold (Sclerotinia sclerotiorum (Lib.) de Bary). As the best known resistance sources are not adapted, the genetic control of white mold in the common bean must be understood to guide breeding more efficiently. The objective of the pr.. Read More»

White mold resistance-associated quantitative trait loci in the Jalo x Small White common bean population
Authors: D.A. Souza, M. Balestre, A.K.A. Pamplona, M.E. Leite, J.A. Dias and J.B. Santos
We aimed to identify simple sequence repeat (SSR) markers linked to quantitative trait loci (QTLs) associated with white mold resistance in a segregating population derived from a cross between common bean cultivars Jalo and Small White, in the Southern State of Minas Gerais. Parents were crossed to obtain the F2 generation of 190 plants. From these, F2:3.. Read More»

Genetic diversity and mycelial compatibility groups of the plant-pathogenic fungus Sclerotinia sclerotiorum in Brazil
Authors: C.G. Litholdo J�ºnior, E.V. Gomes, M. Lobo J�ºnior, L.C.B. Nasser and S. Petrofeza
The genetic variability of 40 Sclerotinia sclerotiorum isolates from various fields widely distributed throughout Brazil and different host crops was analyzed using RAPD markers and mycelial compatibility groupings (MCGs). The isolates were characterized using 16 random primers of the OPERON series, which produced 121 DNA frag.. Read More»

Investigation of Sclerotinia sclerotiorum strains variability in Brazil
Authors: M.J. Abreu and E.A. Souza
White mold is a common bean disease caused by the fungus Sclerotinia sclerotiorum, resulting in economic losses in Brazil and worldwide. Lack of knowledge about the population structure of the pathogen makes it difficult to control the disease. The aim of this study was to characterize strains of S. sclerotiorum obtained from experimental and commercial c.. Read More»
