Squalene Cyclases and Cycloartenol Synthases from Polystichum polyblepharum and Six Allied Ferns
Molecules, 2018 Ferns are the most primitive of all vascular plants. One of the characteristics distinguishing them from flowering plants is its triterpene metabolism. Most cyclic triterpenes in ferns are hydrocarbons derived from the direct cyclization of squalene by ...

Physik in unserer Zeit, EarlyView.Sehen ist der erste Schritt in Richtung Verstehen. Dieses Prinzip gilt von der Beobachtung ferner Galaxien bis hin zur Untersuchung einzelner Atome und hält damit über viele Größenordnungen. Heutzutage ermöglichen moderne Mikroskope die Beobachtung einzelner Atome und sogar die gezielte Kontrolle chemischer Reaktionen einzelner Moleküle ...

The most threatened plants receive the least scientific attention
PLANTS, PEOPLE, PLANET, EarlyView.Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

Water-Carbon Relations in Ferns
As the second most species-rich vascular group after angiosperms and boasting 430 million years of evolution, ferns stand as a valuable model system for exploring the evolution of land plants, exhibiting a diverse array of adaptations to both ancestral ...
