PREMISE OF THE STUDY: The evolution of novel fruit morphologies has been integral to the success of angiosperms. The inflated fruiting calyx, in which the balloon-like calyx swells to completely surround the fruit, has evolved repeatedly across angiosperms and is postulated to aid in protection and dispersal. Here we investigate the evolution of th...
Deprea is a neotropical genus that comprises 51 species. Recent work based on molecular data has explored its monophyly and interspecific relationships, but the relationships amongst Deprea species were not entirely elucidated. The inclusion of more accessions and molecular markers in phylogenetic analysis is likely to produce more supported hypoth...
Effective mentoring implies a two-way relationship in which mentees obtain benefits from the knowledge and training provided by mentors, and mentors gain the possibility of contemplating and learning new perspectives, of self-evaluating their roles and, in consequence, growing as professionals 1,2. Mentorship relationships cannot be separated from...
Within the cosmopolitan family Solanaceae, Physalideae is the tribe with the highest generic diversity (30 genera and more than 200 species). This tribe embraces subtribe Physalidinae, in which phylogenetic relationships of some genera are not entirely resolved. Chromosomes may help on resolution, by providing information on the processes underlyin...
Premise
Solanaceae is a scientifically and economically important angiosperm family with a minimal fossil record and an intriguing early evolutionary history. Here, we report a newly discovered fossil lantern fruit with a suite of features characteristic of Physalideae within Solanaceae. The fossil comes from the early Eocene Laguna del Hunco site...
We present a complete list of Solanaceae species from Caquetá Department, Colombia, including their distribution by municipalities and conservation status. We also provide a dichotomous key to the genera. Overall, 114 species of 21 Solanaceae genera are listed, with Solanum L. the best represented with almost half of the species. The municipality w...
The genus Sclerophylax (Atropina clade, Solanaceae) has 14 species recognized to date, all except two endemic to Argentina. To clarify its phylogenetic relationships, molecular sequence data from the trnL‐trnF and the rpl32F‐trnL intergenic spacer regions, the waxy gene and the ITS region were employed in maximum likelihood and Bayesian inference a...
The Solanaceae family, also referred to as nightshades or the tomato family, includes a wide variety of morphologies and habits. It has a distinct evolutionary history driven by natural selection, among other processes, which has resulted in unique adaptations and rewarding biochemical pathways for pollinators. The Solanaceae family contains 99 gen...
Mentor relationships are crucial to retention, success, and wellbeing of women and underrepresented minority scientists in academia. A network of diverse mentors may support achieving long-term career goals, advancement, and retention of both mentors and mentees, thus enhancing diversity, equity, and inclusion initiatives. Diversified mentorship is...
Dissecting the relationship between gene function and substitution rates is key to understanding genome-wide patterns of molecular evolution. Biochemical pathways provide powerful systems for investigating this relationship because the functional role of each gene is often well characterized. Here, we investigate the evolution of the flavonoid pigm...
Syndromes, wherein multiple traits evolve convergently in response to a shared selective driver, form a central concept in ecology and evolution. Recent work has questioned the existence of some classic syndromes, such as pollination and seed dispersal syndromes. Here, we discuss some of the major issues that have afflicted research into syndromes...
This review summarizes and discusses the knowledge of cytogenetics in Solanaceae, the tomato family, its current applications, and prospects for making progress in fundamental systematic botany and plant evolution. We compile information on basic chromosome features (number, size, morphology) and molecular cytogenetics (chromosome banding and rDNA...
The subtribe Iochrominae (Solanaceae) is represented in Brazil by two species, both with broad morphological variation. No study focusing on this subtribe has been published for the country to date. Therefore, the aim of this study is to provide a taxonomic treatment for the Iochrominae occurring in Brazil. Iochroma arborescens is widely distribute...
Evolutionary transitions in flower color often trace back to changes in the flavonoid biosynthetic pathway and its regulators. In angiosperms, this pathway produces a range of red, purple, and blue anthocyanin pigments. Transcription factor (TF) complexes involving members of the MYB, bHLH, and WD40 protein families control the expression of pathwa...
Syndromes, wherein multiple traits evolve convergently in response to a shared selective driver, form a central concept in ecology and evolution. Recent work has questioned the utility and indeed the existence of some of the classic syndromes, such as pollination and seed dispersal syndromes. Here, we discuss some of the major issues that have plag...
