Pycreus rubidomontanus (Cyperaceae), a widespread but undescribed species from tropical West Africa
Pycreus rubidomontanus is described as a new species. It is relatively widespread in tropical West Africa where it had been confused up to present with P. atrorubidus, a very rare endemic species from Zambia in south-central Africa that probably is known only from the type gathering. Differences between these and...Verloove, Filip ; Browning, Jane ; Mesterhazy, Attila

Progress, challenges and opportunities for Red Listing
Despite its recognition as an important global resource for conservation, the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species only provides assessments of extinction risk for a small and biased subset of known biodiversity. A more complete Red List can better support species-level conservation by indicating...Bachman, Steven ; Field, Richard ; Reader, Tom ; Raimondo, Domitilla ; Donaldson, John …

Prediction of pathogenicity genes involved in adaptation to a lupin host in the fungal pathogens Botrytis cinerea and Sclerotinia sclerotiorum via comparative genomics
Narrow-leafed lupin is an emerging crop of significance in agriculture, livestock feed and human health food. However, its susceptibility to various diseases is a major obstacle towards increased adoption. Sclerotinia sclerotiorum and Botrytis cinerea – both necrotrophs with broad host-ranges - are reported among the top 10 lupin pathogens. Whole-genome...Mousavi-Derazmahalleh, Mahsa ; Chang, Steven ; Thomas, Geoff ; Derbyshire, Mark ; Bayer, Phillip …

Polyploidy in the Conifer Genus Juniperus: An Unexpectedly High Rate
Recent research suggests that the frequency of polyploidy may have been underestimated in gymnosperms. While there are few reports of polyploids in the genus Juniperus, data are still missing for most species. In this study, we evaluated the extent of polyploidy in Juniperus by conducting the first comprehensive screen across...Farhat, Perla ; Hidalgo, Oriane ; Robert, Thierry ; Siljak-Yakovlev, Sonja ; Leitch, Ilia …
