Bimetallic Cu/Zn Single‐Atom Nanozyme with Superoxide Dismutase‐Like Activity

open access: yesSmall, EarlyView.
A novel Cu/Zn dual‐site single‐atom nanozyme is synthesized via a PVP‐assisted MOF‐derived strategy, mimicking natural CuZn‐superoxide dismutase enzyme with high selectivity. The catalyst exhibits robust superoxide dismutation activity without undesired oxidase or peroxidase functions and effectively scavenges reactive oxygen species in complex ...

Next‐generation sequencing sheds new light on a major lineage of Acanthaceae, clarifying previously uncertain relationships in Barlerieae

open access: yesTAXON, EarlyView.
Abstract The Acanthaceae tribe Barlerieae is an understudied lineage that consists of ca. 500 species, many of which are rare and range restricted. Though understudied, it is clear that many species play vital roles in tropical ecosystems, including supporting a wide range of pollinators and herbivores. The tribe contains 13 genera, the two largest and

Phylogeny and new sectional classification for the Cape Clade of the genus Indigofera (Fabaceae: Indigofereae)

open access: yesTAXON, EarlyView.
Abstract The genus Indigofera in the Greater Cape Floristic Region (GCFR) comprises a diverse assortment of species. Almost 90% of the region's Indigofera species belong to the Cape Clade, while the remaining species are scattered among the other three globally distributed Indigofera clades.

Taxonomy and dated molecular phylogeny of Allium oreophilum sensu lato (A. subg. Porphyroprason) uncover a surprising number of cryptic taxa

open access: yesTAXON, EarlyView.
Abstract Allium oreophilum, hitherto the representative of the monotypic A. subg. Porphyroprason from the second evolutionary lineage of Allium, is studied in detail. Over about 150 years, A. oreophilum was regarded as a somewhat polymorphous species with two synonyms, all described in the 19th century.
