The Crop-Group and the inconsistent use of Linnean names in the taxonomy of domesticated plants

There have been several proposals for classification categories for systematic groups of domesticated plants. In the 6th edition of the International Code for Nomenclature of Cultivated Plants (ICNCP) only two main categories were included, the cultivar and the cultivar-group. The 7th edition of ICNCP saw the introduction of the Group to encompass the cultivar-group together with other kinds of groupings, also of unnamed material. Despite the existence of the ICNCP, many names for systematic groups of domesticated plants are still in purely Linnean form, following the rules of the International Code of Botanical Nomenclature (ICBN). This practice illustrates a lack of insight in the workings and logic of systematic thinking with respect to domesticated plants and muddles the borderline between the contexts of domestication and evolution. The inclusion of the Crop category in the ICNCP would accommodate the nomenclature and classification of all systematic groups of domesticated plants in one logically consistent system, setting it apart from the realm of the classical botanical classification in use for wild plants

Morphological character evolution of Amorphophallus (Araceae) based on a combined phylogenetic analysis of trnL, rbcL, and LEAFY second intron sequences

Sequences of three different genes in 69 taxa of Amorphophallus were combined to reconstruct the molecular phylogeny of this species-rich Aroid genus. The data set was analyzed by three different methods, Maximum Parsimony, Maximum Likelihood and Bayesian analysis, producing slightly different tree topologies. Three major clades identified in all analyses reflect the biogeographical distribution of Amorphophallus. Some clades were supported by morphological characters such as sessile/nonsessile stigma, pollen opening mechanism, shape of the main segments of the lamina, growth cycle, and berry colour. When optimised, a nonsessile stigma may have evolved from a sessile one with several reversals. Pollen opening by connective rupturing evolved from pollen opening by pores. Unequally shaped segments of the lamina evolved from equally shaped segments. Simultaneously existing leaf and inflorescences evolved from alternating leaves and inflorescences. Blue, purple, green, and yellow berries evolved from red/orange/white ones

Design principles for homogeneous water oxidation catalysts based on first–row transition metals

The development of homogeneous first-row transition metal (FRTM) catalysts for the water oxidation reaction is considerably more challenging than for second and third-row catalysts. Given that FRTM catalysts are, in general, more labile, additional design principles must be considered to develop robust and stable catalysts for the water oxidation reaction. In this review, we highlight important design criteria and summarize important lessons learned for FRTM water oxidation catalysts.Catalysis and Surface Chemistr
