Lingyuanfructus: The First Fossil Angiosperm with Naked Seeds [PDF]

Life
Unlike gymnosperms with naked ovules, angiosperms are defined and characterized by their enclosed ovules. According to plant evolution theories, angiosperms should be derived from their gymnospermous ancestors, which have naked ovules.

Variation in the angiosperm ionome [PDF]

Physiologia Plantarum, 2018
The ionome is defined as the elemental composition of a subcellular structure, cell, tissue, organ or organism. The subset of the ionome comprising mineral nutrients is termed the functional ionome. A ‘standard functional ionome’ of leaves of an ‘average’

The Landscape of Integrated Domains of Angiosperm NLR Genes Reveals Continuous Architecture Evolution of Plant Intracellular Immune Receptors [PDF]

Plants
Nucleotide-binding site-leucine-rich repeat (NLR) proteins are key intracellular immune receptors in plants. Integrated domains (IDs) can occasionally be fused with NLRs, contributing to their functional diversity. However, the diversity and evolutionary

Different Methodologies Result in Opposite Patterns of Diversification Rates in Flowering Plants Across Latitudes [PDF]

Ecology and Evolution
There are two major groups of methods estimating diversification rates: One group depends on well resolved phylogenies and the other is phylogeny‐free.

Pseudanthia in angiosperms: a review [PDF]

Annals of Botany, 2023
AbstractBackgroundPseudanthia or ‘false flowers’ are multiflowered units that resemble solitary flowers in form and function. Over the last century the term ‘pseudanthium’ has been applied to a wide array of morphologically divergent blossoms, ranging from those with easily noticeable florets to derived, reduced units in which individual flowers become

Ants sow the seeds of global diversification in flowering plants [PDF]

, 2009
Background: The extraordinary diversification of angiosperm plants in the Cretaceous and Tertiary periods has produced an estimated 250,000–300,000 living angiosperm species and has fundamentally altered terrestrial ecosystems.

Competition and Niche Differentiation of Water and Nutrients between Broussonetia papyrifera and Platycladus orientalis under Prolonged Drought Stress

Agronomy, 2022
Little is known about the competition between and niche differentiation of water and nutrients between angiosperm and gymnosperm tree species under prolonged drought stress, especially in fragile environments.

The root of the angiosperms revisited [PDF]

Proceedings of the National Academy of Sciences, 2002
Most recent phylogenetic analyses of basal angiosperms have converged on the placement ofAmborellaas sister to all other extant angiosperms. However, certain recent studies suggest thatAmborellaand Nymphaeales (water lilies) form a clade sister to all remaining angiosperms or that Nymphaeales alone are the sister to the remaining angiosperms. We report
