| dc.description | Fungicides to control mycopathogens of commercial Agaricus bisporus, a mushroom cultivated for human consumption, are a major field of study, since these chemicals are toxic to both the host and its fungal parasites. The fungicide Prochloraz-Mn, used at its LD50 for A. bisporus, partially inhibited protein biosynthesis in the vegetative mycelial cell walls of this mushroom and caused significant changes in cell-wall polysaccharide structure, as deduced by methylation analysis and gas liquid chromatography-mass spectrometry (GLC-MS). Furthermore, the aggregated mycelial walls showed distinct alterations in their overall chemical composition following the administration of Prochloraz-Mn at the LD50 and the LD50 ×1000. As expected, GLC-MS studies indicated that the latter dose caused more appreciable differences in polysaccharide structure. The decrease in mushroom crop yields obtained from industrial cultures treated with Prochloraz-Mn to control V. fungicola infection depended on the dose of the fungicide employed, whereas fruit-body morphology was only slightly affected at the highest Prochloraz-Mn concentration used. | - |
| dc.description | Los fungicidas para el control de micopatógenos de Agaricus bisporus, un hongo de cultivo comercial para consumo humano, representan un importante tema de estudio debido a que son tóxicos tanto para el huésped como para sus parásitos fúngicos. El fungicida Prochloraz-Mn, empleado a su LD50 para A. bisporus, inhibe parcialmente la biosíntesis de proteínas en las pared celular del micelio vegetativo de este hongo y provoca cambios significativos en la estructura polisacárida de la pared celular, tal como se observa mediante el análisis de metilación y la cromatografía líquida de gases-espectrometría de masa (GLC-MS). Además, las paredes agregadas del micelio presentan diferentes alteraciones en la composición química global después de la administración de Prochloraz-Mn a la LD50 y LD50 ×1000. Como cabría esperar, los estudios de GLC-MS, indican que la última dosis causa más diferencias apreciables en la estructura polisacárida. La disminución en la producción del hongo en los cultivos industriales tratados con Prochloraz-Mn para controlar la infección por V. fungicola, dependía de la dosis de fungicida empleada, mientras que la morfología del cuerpo fructífero sólo resulta ligeramente afectada a la concentración de Prochloraz-Mn más elevada. | - |
