A high-quality Buxus austro-yunnanensis (Buxales) genome provides new insights into karyotype evolution in early eudicots [PDF]
BMC Biology, 2022 Background Eudicots are the most diverse group of flowering plants that compromise five well-defined lineages: core eudicots, Ranunculales, Proteales, Trochodendrales, and Buxales.

Leveraging off higher plant phylogenetic insights for antiplasmodial drug discovery [PDF]
Natural Products and Bioprospecting, 2023 The antimalarial drug-resistance conundrum which threatens to reverse the great strides taken to curb the malaria scourge warrants an urgent need to find novel chemical scaffolds to serve as templates for the development of new antimalarial drugs. Plants

Buxus and Tetracentron genomes help resolve eudicot genome history [PDF]
Nature Communications, 2022 Gamma triplication arises via two whole-genome duplications early in eudicot history, but the relative timing of these is unclear. Here, the authors report the genomes of Buxales and Trochodendrales and reject the hypothesis of gamma arising via inter ...

Phylogenetic analysis of fossil flowers using an angiosperm-wide data set: proof-of-concept and challenges ahead. [PDF]
Am J Bot, 2020 Premise Significant paleobotanical discoveries in recent decades have considerably improved our understanding of the early evolution of angiosperms and their flowers. However, our ability to test the systematic placement of fossil flowers on the basis of phylogenetic analyses has remained limited, mainly due to the lack of an adequate, angiosperm‐wide ...

The genome sequence of common box, Buxus sempervirens L. (Buxaceae) [version 2; peer review: 2 approved] [PDF]
Wellcome Open ResearchWe present a genome assembly from an individual Buxus sempervirens (common box; Streptophyta; Magnoliopsida; Buxales; Buxaceae). The genome sequence has a total length of 676.70 megabases.

The genome of the king protea, Protea cynaroides. [PDF]
Plant J, 2023 SUMMARY The king protea (Protea cynaroides), an early‐diverging eudicot, is the most iconic species from the Megadiverse Cape Floristic Region, and the national flower of South Africa. Perhaps best known for its iconic flower head, Protea is a key genus for the South African horticulture industry and cut‐flower market.

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Plant Environ InteractExponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Is There a Key Primer for Amplification of Core Land Plant DNA Barcode Regions (rbcL and matK)? [PDF]
Ecol EvolWe use in silico PCR to select and measure the amplification capability of primer. We tested 366 and 489 published primers for the rbcL and matK regions, respectively, using sequences from 8463 different land plant species. Our results indicate a set of primers that effectively cover all land plant sequences, particularly for the rbcL region.

Complete plastid genome sequencing of Trochodendraceae reveals a significant expansion of the inverted repeat and suggests a Paleogene divergence between the two extant species. [PDF]
PLoS ONE, 2013 The early-diverging eudicot order Trochodendrales contains only two monospecific genera, Tetracentron and Trochodendron. Although an extensive fossil record indicates that the clade is perhaps 100 million years old and was widespread throughout the ...

Angiosperm flowers reached their highest morphological diversity early in their evolutionary history. [PDF]
New PhytolSummary Flowers are the complex and highly diverse reproductive structures of angiosperms. Because of their role in sexual reproduction, the evolution of flowers is tightly linked to angiosperm speciation and diversification. Accordingly, the quantification of floral morphological diversity (disparity) among angiosperm subgroups and through time may ...
