Taxonomic revision of Saxicolella (Podostemaceae), African waterfall plants highly threatened by Hydro-Electric projects.
Species of the genus Engl. (Podostemaceae) are African rheophytes, restricted to rapids and waterfalls as are all members of the family. Previously, was shown to be polyphyletic with two separate clades. The name Engl. was recently resurrected for one clade that is sister to the American genera (Tul.) Wedd., Michx.... -

Does oxygen affect ageing mechanisms of Pinus densiflora seeds? A matter of cytoplasmic physical state.
During desiccation, the cytoplasm of orthodox seeds solidifies into an intracellular glass with highly restricted diffusion and molecular mobility. Temperature and water content govern seed ageing rates, while oxygen (O2) can promote deteriorative reactions. However, whether the cytoplasmic physical state affects involvement of O2 in seed ageing remains unresolved. We... -
