Abstract
Se ha corroborado la existencia de marcadas diferencias de sensibilidad de
varios hongos filamentosos frente a ciertos metabolitos naturales de origen vegetal.
Estas distintas sensibilidades constituyen marcadores que permiten el diseno de métodos de selección y análisis de híbridos obtenidos en experiencias de fusión celular
somática, evitándose así la manipulación del genoma de la cepa original para la obtención de marcadores genéticos (auxotrofías, resistencias ... ) imprescindibles en todos los métodos de selección utilizados hasta el momento.
Dada la escasez cuantitativa y cualitativa de fungicidas de síntesis resulta
interesante el alto poder inhibidor del crecimiento de bacterias y hongos presentado
por el extracto hidro-alcohólico de Clematis vitalba, que además de ser comparable
en eficacia a los productos comerciales, presenta la ventaja de ser termoestable en
las condiciones de esterilización por autoclave y actuar en fase acuosa, lo que facilita
su manejo en el laboratorio, no debiendo descartarse la posibilidad de su posible uso
como fungicida comercial.
The existence in severa1 filamentous fungi of remarkable differences in sensitivity to certain natural metabolites with a vegetable origin has been corroborated. These differences in sensitivity can be used as markers which make possible the experimental design for the selection and analysis of hybrida released from somatic cellular fusion, so avoiding the manipulation of the genome of the original strain. Considering the quantitative and qualitative shortage of synthetic fungicides, the high inhibitory power on the bacteria1 and fungal growth of the hydroalcoholic extract of Clematis vitalba is very interesting. Furthermore, this extract is so effective as the trading goods and it presents the advantages of: (1) being thermo-stable at the autoclaving conditions and (2) acting in the watery phase; this makes easy its use in the laboratory. The possibility of its feasible usage as a commercial fungicyd can not be discarded.
