“…One strategy that has been applied is the systematic analysis of a plant group which produces many classes of secondary metabolites (Markham & Porter, 1978;Soeder, 1985;Soares, 1992;Paiva, Kaplan & Gottlieb, 1995). A macrosystematic analysis of the evolutionary link between morphology and micromolecules in flowering plants has been achieved by studying a micromolecular class with broad occurrence (Borin & Gottlieb, 1988;Gottlieb et al, 1994;Figueiredo, Kaplan & Gottlieb, 1995; Sampaio-Santos, Kaplan Soares, Kaplan & Gottlieb, 1995).…”

“…They form the second largest group of vascular plants and they are a significant, sometimes dominant, component of many plant communities. Furthermore, they are rich in secondary compounds (Soeder, 1985), some of which might provide medicinal drugs, insecticides or antibiotics. It is therefore, a matter for concern that more than 10% of the 12 000 species of ferns are threatened with extinction (Kramer and Green, 1990), largely because of habitat destruction by man.…”

Natural soil spore banks — can they be used to retrieve lost ferns?

Some fern species form spore banks -reservoirs in the soil of viable spores which remain dormant while buried but germinate in light if brought to the surface. The recently discovered characteristics of these spore banks are described. Enough is now known to suggest that they might have a role in the conservation of endangered fern species as alternatives to ex situ collections of sporophytes, gametophytes and spores, the relative merits of which are also considered. Mature sporophytes of several British species have now been raised from natural spore banks in soil samples; if this proves to be possible also for endangered species, some interesting options become available. The possibilities are discussed of augmenting surviving populations and increasing their genetic diversity, even perhaps of retrieving lost populations, by reintroduction of spore bankderived plants or by stimulating regeneration from spore banks in situ. Botanic gardens are well placed to provide the further research, the regular monitoring of endangered populations, and the taxonomic and horticultural support required to realise these possibilities.

“…Entre los principales grupos de metabolitos identificados en los extractos de C. pteridoides, se encuentran aminas y triptaminas, ésteres, aldehídos y cetonas, y en menor proporción, algunos taninos y cardiotónicos, lo cual guarda relación con lo reportado en la literatura científica respecto a la composición de los helechos de este género (11,23). El efecto diurético observado con los extractos de esta planta está relacionado con la presencia de estos constituyentes y se requieren posteriores estudios que permitan determinar cuáles son los responsables de la actividad y, asimismo, profundizar en sus mecanismos de acción.…”
