Extinction risk and threats to plants and fungi
Societal Impact Statement There is increasing awareness that plants and fungi, as natural solutions, can play an important role in tackling ongoing global environmental challenges. We illustrate how understanding current and projected threats to plants and fungi is necessary to manage and mitigate risks, while building awareness of gaps and... -

Crop wild phylorelatives (CWPs): phylogenetic distance, cytogenetic compatibility and breeding system data enable estimation of crop wild relative gene pool classification
Enabling food security requires access to a broad range of genetic resources to facilitate crop breeding. This need is increased in a climate change scenario, which will require the production of novel crops adapted to new conditions. However, many major crops have reduced genetic diversity due to the genetic bottlenecks...Viruel, Juan ; Kantar, Michael B ; Gargiulo, Roberta ; Hesketh-Prichard, Peri ; Leong, Nathan …

Introgression across evolutionary scales suggests reticulation contributes to Amazonian tree diversity
Hybridisation has the potential to generate or homogenize biodiversity and is a particularly common phenomenon in plants, with an estimated 25% of plant species undergoing inter‐specific gene flow. However, hybridisation in Amazonia’s megadiverse tree flora was assumed to be extremely rare despite extensive sympatry between closely related species, and its... -

Toward Unifying Global Hotspots of Wild and Domesticated Biodiversity
Global biodiversity hotspots are areas containing high levels of species richness, endemism and threat. Similarly, regions of agriculturally relevant diversity have been identified where many domesticated plants and animals originated, and co-occurred with their wild ancestors and relatives. The agro-biodiversity in these regions has, likewise, often been considered threatened. Biodiversity... -

Plant richness, turnover, and evolutionary diversity track gradients of stability and ecological opportunity in a megadiversity center
Research on global patterns of diversity has been dominated by studies seeking explanations for the equator-to-poles decline in richness of most groups of organisms, namely the latitudinal diversity gradient. A problem with this gradient is that it conflates two key explanations, namely biome stability (age and area) and productivity (ecological...Colville, Jonathan F. ; Beale, Colin M. ; Forest, Félix ; Altwegg, Res ; Huntley, Brian …

Conserving orthodox seeds of globally threatened plants ex situ in the Millennium Seed Bank, Royal Botanic Gardens, Kew, UK: the status of seed collections
We reviewed the status of orthodox seed collections of globally threatened plants conserved in − 20 °C long-term storage at the Millennium Seed Bank, Royal Botanic Gardens, Kew, UK in terms of their geographic and bioclimatic representativeness, taxonomic and genetic diversity, quality and physiological status. The comprehensive dataset used spans... -

Interfamilial relationships in order Fabales: new insights from the nuclear regions sqd1 and 26S rDNA
Leguminosae, Polygalaceae, Quillajaceae and Surianaceae together comprise the order Fabales. Phylogenetic relationships within Fabales remain an unsolved problem even though interfamilial relationships have been examined in a number of studies using different sampling approaches and both molecular and morphological data. In this study, we gather information from the nuclear 26S...Aygoren Uluer, Deniz ; Hawkins, Julie A. ; Forest, Félix

From the frying pan: an unusual dwarf shrub from Namibia turns out to be a new brassicalean family
Tiganophyton karasense, an evergreen dwarf shrub, is described as a new species. A new genus and family are also proposed for it in the order Brassicales. Phylogenetic analysis of DNA sequence data indicate that Tiganophyton is sister to Bataceae/Salvadoraceae, and all three sister to Koeberliniaceae. First realized to be undescribed...
