Phylogenomics and the rise of the angiosperms [PDF]
AbstractAngiosperms are the cornerstone of most terrestrial ecosystems and human livelihoods1,2. A robust understanding of angiosperm evolution is required to explain their rise to ecological dominance. So far, the angiosperm tree of life has been determined primarily by means of analyses of the plastid genome3,4.

Dry Climate Filters Gymnosperms but Not Angiosperms through Seed Mass
In the context of climate change in recent years, the fate of woody plant seed has an important impact on forest regeneration. Seed mass is an important reproductive strategy of plants. There are huge differences between gymnosperms (mainly conifers) and

Hydraulic consequences of vessel evolution in angiosperms [PDF]
We tested two hypotheses for how vessel evolution in angiosperms influenced xylem function. First, the transition to vessels decreased resistance to flow—often considered the driving force for their evolution.

Water transport in vesselless angiosperms: Conducting efficiency and cavitation safety [PDF]
Two structure‐function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low‐resistance torus‐margo pits.

Wood from Angiosperms and Gymnosperms Shows Distinctive Lignin Peaks in Direct Analysis in Real Time (DART) Mass Spectra [PDF]
A data set was constructed consisting of 3021 mass spectra randomly selected from the ForeST© (Forensic Spectra of Trees) database of mass spectra for wood analyzed by Direct Analysis in Real Time ionization coupled with time-of-flight mass spectrometry (

Pseudanthia in angiosperms: a review [PDF]
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

The root of the angiosperms revisited [PDF]
Most recent phylogenetic analyses of basal angiosperms have converged on the placement of Amborella as sister to all other extant angiosperms. However, certain recent studies suggest that Amborella and Nymphaeales (water lilies) form a clade sister to ...

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