| dc.description | En el presente trabajo se estudiaron 134 aislamientos dicarióticos mediante la electroforesis horizontal en geles de poliacrilamida, para ocho actividades enzimáticas: AAT, ACP, AKP, EST, MDH, MNR, PRX y SOD. Se analizaron 94 bandas totales, y con el fin de discernir micelios individuales, se implementaron tests de incompatibilidad somática. Por otra parte, se examinaron los caracteres macro- y micromorfológicos, tanto al MO como al MEB, de ca. 200 especímenes, incluyendo 28 holotipos de los Herbarios BPI, H, L, PC, NY, FH, K, PH, SP, BAFC y LPS. Analizando numéricamente los patrones de bandas isoenzimáticas y los caracteres morfológicos, se pudo establecer cierta correlación entre los datos moleculares y los morfológicos. Se observaron varios fenotipos alozímicos en cada sistema enzimático. No se encontraron bandas diagnósticas para especies determinadas morfológicamente. Sin embargo, se hallaron bandas diagnóstico en el ámbito de los dos subgéneros, Ganoderma y Elfvingia, corroborando los resultados proporcionados por los caracteres morfológicos. En total, se detectó en el área bajo estudio, la presencia de nueve especies del subgénero Ganoderma y ocho especies del subgénero Elfvingia. | - |
| dc.description | In the present work 134 dikaryotic isolates of Ganoderma were examined by horizontal polyacrylamide gel electrophoresis (PAGE) for eight enzymatic activities: AAT, ACP, AKP, EST, MDH, MNR, PRX and SOD. A total of 94 bands were analysed. In order to discern fungal individuals somatic incompatibility tests were used. On the other hand, both macro- and microscopic structures of ca. 200 specimens were examined and in the latter case both with LM and SEM, which involved the study of 28 holotypes from the Herbaria BPI, H, L, PC, NY, FH, K, PH, SP, BAFC and LPS. By analysing numerically the isoenzymatic patterns and the morphological characters, a certain correlation between molecular and morphological data was established. The zymograms showed that within each enzyme system several allozyme phenotypes could be observed. The enzymatic systems analysed failed to yield diagnostic bands for each morphologically defined group. However, diagnostic bands for the two large subgenera, Ganoderma and Elfvingia, were encountered. Thus corroborating the results furnished by morphological characters. In total, the presence of 9 species of the subgenus Ganoderma and 8 species of the subgenus Elfvingia, was recognized for the area under study. | - |
