Chloranthus genome provides insights into the early diversification of angiosperms
Nature Communications, 2021 Chloranthales remain the last major mesangiosperm lineage without a nuclear genome assembly. We therefore assemble a high-quality chromosome-level genome of Chloranthus spicatus to resolve enigmatic evolutionary relationships, as well as explore patterns

Genetic contribution of paleopolyploidy to adaptive evolution in angiosperms.
Molecular Plant, 2020 Ancient whole-genome duplications (WGD or polyploidy) are prevalent in plants, and some WGDs occurred during the timing of severe global environmental changes. It has been suggested that WGDs may have contributed to plant adaptation.

Frontiers in Ecology and Evolution, 2023 The recently proposed concept of ´endangered living fossils’ (ELFs) integrates high-endangered status and evolutionary singularity for any species. In this review, I gathered monotypic genera (single-species genera) that satisfy the three ELF criteria ...

Non-equilibrium dynamics and floral trait interactions shape extant angiosperm diversity. [PDF]
, 2016 Why are some traits and trait combinations exceptionally common across the tree of life, whereas others are vanishingly rare? The distribution of trait diversity across a clade at any time depends on the ancestral state of the clade, the rate at which ...

The rise of angiosperms pushed conifers to decline during global cooling
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Competition for common resources can make some species groups thrive and others decline. Flowering plants rose to dominance between 125 and 80 Ma, undergoing an explosive radiation that is believed to have impacted long-established plant ...

Geochemical support for a climbing habit within the Paleozoic seed fern genus Medullosa [PDF]
, 2011 A long-standing problem in paleobotany is the accurate identification of the growth habits and statures of fossil plants. Tissue-specific analysis of stable carbon isotope ratios in plant fossils can provide an independent perspective on this issue ...

Phylogenomic Insights into Deep Phylogeny of Angiosperms Based on Broad Nuclear Gene Sampling
Plant Communications, 2020 Angiosperms (flowering plants) are the most diverse and species-rich group of plants. The vast majority (∼99.95%) of angiosperms form a clade called Mesangiospermae, which is subdivided into five major groups: eudicots, monocots, magnoliids ...

The Plant Short-Chain Dehydrogenase (SDR) superfamily:genome-wide inventory and diversification patterns [PDF]
, 2012 Background Short-chain dehydrogenases/reductases (SDRs) form one of the largest and oldest NAD(P)(H) dependent oxidoreductase families. Despite a conserved 'Rossmann-fold' structure, members of the SDR superfamily exhibit low sequence similarities, which
