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... -

A revision of the genus Ruagea (Meliaceae: Melioideae).
The neotropical genus H.Karst. is revised. Fifteen species are recognised, including three T.D.Penn., T.D.Penn. and T.D.Penn. which are described as new to science. A key to the species is presented, along with information on the morphology, distribution, ecology, conservation assessments, local names, uses and field characters. All species are mapped...Pennington, Terence D. ; Barker, Amy ; Rojas-Andres, Blanca M.

Validating South Sudan as a Center of Origin for Coffea arabica: Implications for Conservation and Coffee Crop Improvement.
Cultivated Arabica coffee outside Ethiopia is plagued by low genetic diversity, compromising disease resistance, climate resiliency and sensory potential. Access to the wider genetic diversity of this species may circumvent some of these problems. In addition to Ethiopia, South Sudan has been postulated as a center of origin for Arabica... -
