PREMISE OF THE STUDY: Taxa inhabiting the California Channel Islands exhibit variation in their degree of isolation, but few studies have considered patterns across the entire archipelago. We studied phylogeography of insular Acmispon argophyllus and A. dendroideus to determine whether infraspecific taxa are genetically divergent and to elucidate patterns of diversification across these islands. METHODS: DNA sequences were collected from nuclear (ADH) and plastid genomes (rpL16, ndhA, psbD-trnT) from >450 samples on the Channel Islands and California...

Understanding the distribution of crop genetic diversity in relation to environmental factors can give insights into the eco-evolutionary processes involved in plant domestication. Yam beans (Pachyrhizus Rich. ex DC.) are leguminous crops native to South and Central America that are grown for their tuberous roots but are seed-propagated. Using a landscape genetic approach, we examined correlations between environmental factors and phylogeographic patterns of genetic diversity in Pachyrhizus landrace populations...

Yellow lupine (Lupinus luteus L., Taper c.), a member of the legume family (Fabaceae L.), has an enormous practical importance. Its excessive flower and pod abscission represents an economic drawback, as proper flower and seed formation and development is crucial for the plant's productivity. Generative organ detachment takes place at the basis of the pedicels, within a specialized group of cells collectively known as the abscission zone (AZ). During plant growth these cells become competent to respond to specific signals that trigger separation and lead to the abolition of cell wall adhesion...

Chronic skin conditions such as atopic dermatitis, psoriasis and aged skin are characterized by defective skin barrier and dryness which are associated with reduced levels of skin ceramides (CERs). The beneficial effects of plant-derived CERs for skin hydration and skin barrier recovery have been shown in several studies. Although plenty of glucosylceramide (GlcCER)-based dietary supplements meant for skin barrier improvement have been marketed, there are limited commercial sources of plant GlcCERs. In an attempt to explore alternative GlcCER sources, a reversed phase LC-MS/MS method with atmospheric pressure chemical ionization (APCI) interface was developed for separation and structural identification of GlcCERs isolated from three plants...

The use of next-generation sequencing (NGS) technologies provides a great volume of genome sequence data even for non-model species. The development of microsatellite markers using these data is a relatively quick and easy process. Dipteryx alata Vogel (Fabaceae) is an arboreal species from the Cerrado biome and is considered an important plant genetic resource. Here, we report the development of microsatellite markers for D. alata using NGS data. DNA samples from four individuals were sequenced using the Illumina MiSeq platform and high-quality reads were assembled into contigs of the D...

The sequestrate (truffle-like) basidiomycete Octaviania ivoryana was originally described based on collections from Zimbabwe, Kenya, Guinea, and Senegal. This species has basidiomes that stain blue-green and basidiospores with crowded spines that are characteristic of the genus Octaviania. However, O. ivoryana is the only Octaviania species described from sub-Saharan Africa, and the phylogenetic relationship of the species to other species of Octaviania sensu stricto has not been previously investigated. We examined the phylogenetic position of the isotype and paratype specimens of O...
