MYB regulator of “colorless” flavonols underlies the evolution of red flowers in <i>Iochroma</i> (Solanaceae) Open
Anthocyanins, the pigments that give rise to blue, purple, red, and pink colors in many flowers and fruits, are produced by the deeply conserved flavonoid biosynthesis pathway. The regulation of this pathway is thus fundamental for species…

Late Cretaceous origins for major nightshade lineages from total evidence timetree analysis Open
Background and Aims The timing of the radiation of nightshades (Solanaceae) has been contentious in the literature, with estimates of the crown age ranging from ca. 30 to 70 Mya (mid-Oligocene to late Cretaceous). The tempo of diversificat…

Polygenetic Determinants of Azole Resistance, Tolerance, and Heteroresistance in<i>Candida albicans</i> Open
Azole antifungals are widely used to treat Candida infections, yet therapeutic failures are common. In addition to resistance, fungal populations can exhibit tolerance and heteroresistance, subpopulation-driven drug responses that can cont…

Flower clades and fruit clades: trade-offs in color diversification across angiosperms Open
PREMISE Flowers and fruits are two major phases of plant reproduction which often use colorful signals to attract animal mutualists. Fleshy fruits develop from the ovaries of flowers, and both organs use the same suites of pigments to crea…

Recruitment of Sugar Transport and Scent Volatile Genes for Prey Attraction in the Nectar Spoon of <i>Heliamphora tatei</i> Open
Prey attraction is an integral component of the carnivorous syndrome, yet its molecular adaptations have remained largely unexplored. Our study utilized tissue‐specific transcriptomic data from the South American marsh pitcher plant, Helia…

Does the abiotic environment influence the distribution of flower and fruit colors? Open
Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions …

View article: Macroevolution of the plant–hummingbird pollination system
Macroevolution of the plant–hummingbird pollination system Open
Plant–hummingbird interactions are considered a classic example of coevolution, a process in which mutually dependent species influence each other's evolution. Plants depend on hummingbirds for pollination, whereas hummingbirds rely on nec…

Patterns recovered in phylogenomic analysis of Candida auris and close relatives implicate broad environmental flexibility in Candida/Clavispora clade yeasts Open
Fungal pathogens commonly originate from benign or non-pathogenic strains living in the natural environment. The recently emerged human pathogen, Candida auris, is one example of a fungus believed to have originated in the environment and …

The Sequential Direct and Indirect Effects of Mountain Uplift, Climatic Niche, and Floral Trait Evolution on Diversification Dynamics in an Andean Plant Clade Open
Why and how organismal lineages radiate is commonly studied through either assessing abiotic factors (biogeography, geomorphological processes, and climate) or biotic factors (traits and interactions). Despite increasing awareness that bot…

Incomplete lineage sorting and hybridization as drivers of tree discordance in Petunia and related genera (Petunieae, Solanaceae) Open
Despite the overarching history of species divergence, phylogenetic studies often reveal distinct topologies across regions of the genome. The sources of these gene tree discordances are variable, but incomplete lineage sorting (ILS) and h…

Phylogenetic Relationships of a North American Radiation of Clematis (Ranunculaceae) Open
Clematis L. is one of many plant genera that contributes prominently to the species richness and endemism of the southeastern United States. Here we examined phylogenetic relationships among species in Clematis sect. Viorna, commonly known…

How does a self‐incompatible individual transition to self‐compatibility during its lifetime? Open
The transition from self-incompatibility (SI) to self-compatibility (SC) has been argued to be one of the most common and influential evolutionary changes in flowering plants (Igic et al., 2008). While the loss of SI may result in an evolu…
