Fungal-host interactions: insights into microRNA in response to Paracoccidioides species.

abstract：:A rational method of search for natural neolignans of desired structures is outlined. This involves consultation of a collection of chemical profiles of plant families. The profiles are assembled considering the biosynthetic class (in the present case lignoids), subclass (neolignans), structural types (neolignan skele...
