Avances y perspectivas sobre el mapeo genético de la resistencia a las pudriciones de la raíz en frijol común
Provedor de dados: 85
Autores: Méndez-Aguilar,R; Reyes-Valdés,MH; Mayek-Pérez,N.
El frijol común es originario de México y es la fuente de proteínas más importante en la alimentación de millones de mexicanos, particularmente los de bajos ingresos económicos. El rendimiento de grano del cultivo es afectado principalmente por una serie de enfermedades causadas por hongos, bacterias y virus. Entre ellas, se destacan las pudriciones de la raíz causadas por los géneros Macrophomina y Fusarium. En la actualidad, con herramientas de la biología molecular como los marcadores moleculares de ADN, es posible desarrollar mapas genéticos donde se ubican QTLs y marcadores moleculares ligados a los genes de resistencia a dichos hongos. La importancia del desarrollo de los mapas genéticos radica en que constituyen el paso previo a la selección...

Provedor de dados: 87
Autores: BANARAS,S.; JAVAID,A.; SHOAIB,A.
ABSTRACT: Urdbean [Vigna mungo (L.) Hepper] is an important leguminous crop whose production is severely affected by charcoal rot disease caused by Macrophomina phaseolina. This study was undertaken to seek an environmental friendly alternative to synthetic fungicides for management of this disease. Dry biomass of an allelopathic weed Sonchus oleraceous L. was used to combat the menace. Fumigated sandy loam pot soil, pre-inoculated with M. phaseolina, was amended with different doses of dry biomass of the weed ranging from 0.5% to 3%. Application of 2% weed biomass completely controlled the disease. Soil inoculation with M. phaseolina inoculation (positive control) reduced shoot dry weight and grain yield of urdbean by 59% and 91%, respectively, over...

Provedor de dados: 87
Autores: BANARAS,S.; JAVAID,A.; SHOAIB,A.; AHMED,E.
ABSTRACT Leaves, stems, roots and inflorescence of the asteraceous weed Circium arvense were extracted in methanol for two weeks. Methanol was evaporated in a rotary evaporator. Different concentrations (1, 2, 3, 4 and 5%) of methanolic extracts were prepared, and their antifungal activities were studied against Macrophomina phaseolina, using malt extract broth as growth medium. In general, extracts of all plant parts showed antifungal activities to variable extents. The highest antifungal activity occurred due to methanolic extract of leaves, followed by stem and root extracts, resulting in 10-74%, 6-57% and 11-39% reduction in fungal biomass over control, respectively. Inflorescence extract showed the least antifungal activity, resulting in 2-30%...

Bioassays Guided Fractionation of Senna occidentalis for Identification of Natural Antifungal Constituents Against Macrophomina phaseolina
Provedor de dados: 87
Autores: JAVAID,A.; QUDSIA,H.; SHOAIB,A.
ABSTRACT Macrophomina phaseolina is one of the most destructive soil-borne fungal plant pathogens. In the present study, different aerial parts of Senna occidentalis were analyzed for their antifungal activity against M. phaseolina. In initial screening bioassays, 0.5-3.0% concentrations of methanolic extracts of fruit, leaf and stem were tested against M. phaseolina. The methanolic leaf extract showed the greatest activity causing up to 29% suppression in biomass production of M. phaseolina. Fractionation of leaf extract of S. occidentalis was carried out with four organic solvents. Bioassays with a range of concentrations (2.34-150 mg mL-1) of these sub-fractions revealed that the chloroform sub-fraction was the most effective, causing 93-98% reduction...

Biological Control of Charcoal Rot of Mungbean by Trichoderma harzianum and Shoot Dry Biomass of Sisymbrium irio
Provedor de dados: 87
Autores: JAVAID,A.; AFZAL,L.; SHOAIB,A.
ABSTRACT: A pot experiment was carried out for the biological control of charcoal rot on mung bean (Vigna radiata), caused by Macrophomina phaseolina. Pot soil was made sick with an inoculum of M. phaseolina. Dried powdered leaves of Sisymbrium irio, a weed from the Brassicaceae family, were mixed in soil at 1, 2 and 3% (w/w) with and without the application of Trichoderma harzianm, a fungal biological control agent. The highest grain yield (3.62 g pot-1) was recorded in a combined application of T. harzianum and 1% S. irio leaf amendment, which was 62% and 805% higher than negative and positive control treatments, respectively. The application of S. irio leaf amendment and T. harzianum generally enhanced leaf protein, sugar and chlorophyll contents, and...

O colapso das ramas é uma importante doença do meloeiro (Cucumis melo) no Nordeste brasileiro. Entretanto, pouco se conhece sobre a importância das ervas daninhas como hospedeiras alternativas dos patógenos causadores do colapso dessa doença no meloeiro. Nesta pesquisa, as ervas daninhas prevalentes foram coletadas em quatro áreas de produção de melão no Nordeste brasileiro durante o período, entre duas estações consecutivas de cultivo e os fungos associados com o sistema radicular foram isolados em culturas puras. Foram coletadas ervas daninhas pertencentes a 16 espécies e 11 famílias botânicas. Dentre os fungos causadores de colapso em meloeiro, das raízes das ervas daninhas foram isolados Macrophomina phaseolina e Rhizoctonia solani. O primeiro fungo...

Provedor de dados: 102
Autores: Almeida,Álvaro M. R.; Amorim,Lilian; Bergamin Filho,Armando; Torres,Eleno; Farias,José R. B.; Benato,Luís C.; Pinto,Mauro C.; Valentim,Nilson.
The increase in incidence of charcoal rot caused by Macrophomina phaseolina on soybeans (Glycine max) was followed four seasons in conventional and no-till cropping systems. In the 1997/98 and 2000/01 seasons, total precipitation between sowing and harvest reached 876.3 and 846.9 mm, respectively. For these seasons, disease incidence did not differ significantly between the no-till and conventional systems. In 1998/99 and 1999/00 precipitation totaled 689.9 and 478.3 mm, respectively. In 1998/99, in the no-till system, the disease incidence was 43.7% and 53.1% in the conventional system. In 1999/00 the final incidence was 68.7% and 81.2% for the no-till and conventional systems, respectively. For these two seasons, precipitation was lower than that...

Autores: Mendoza,José Luis Hernández; Pérez,María Isabel Sánchez; Prieto,Juan Manuel González; Velásquez,Jesús DiCarlo Quiroz; Olivares,Jesús Gerardo García; Langarica,Homar Rene Gill.
Abstract Sampling of agricultural soils from the Mexican northeastern region was performed to detect Trichoderma spp., genetically characterize it, and assess its potential use as a biologic control agent against Macrophomina phaseolina. M. phaseolina is a phytopathogen that attacks over 500 species of cultivated plants and causes heavy losses in the regional sorghum crop. Sampling was performed immediately after sorghum or corn harvest in an area that was approximately 170 km from the Mexico-USA border. Sixteen isolates were obtained in total. Using colony morphology and sequencing the internal transcribed spacers (ITS) 1 and 4 of 18S rDNA, 14 strains were identified as Trichoderma harzianum, T. koningiopsis and T. virens. Subsequently, their antagonistic...
