A defining feature of angiosperms is double fertilization involving the female gametophyte central cell and formation of a nutrient-storing tissue called endosperm. The route for the evolutionary ...
Early angiosperms represent a pivotal chapter in plant evolution, marked by rapid diversification and profound ecological impact during the Early Cretaceous. These flowering plants, distinguished by ...
Paleontologists may be on the verge of solving one of the great mysteries in the history of life on our planet – the origin of angiosperms, the flowering plants. The importance of angiosperms cannot ...
High-throughput sequencing is fundamentally altering traditional phylogenetic classifications. While the Angiosperm Phylogeny Group (APG) III system based on chloroplast sequences has opened up a new ...

Flowering plant origins: Dosage-sensitive genes suggest no whole-genome duplications in ancestral angiosperm
Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution have long been a central question in plant evolutionary biology.
Trees are typically organized into two categories: hardwoods (angiosperms) and softwoods (gymnosperms). A new study suggests that there is a third type of wood—known as “midwood”—that could explain ...
ARGUABLY the world’s weirdest plant, Welwitschia mirabilis is a tangled mass of shredded, fraying leaves in the Namib desert. For a thousand years, perhaps more, it grows just two long leaves, which ...
They are very tiny, but they are a key source of information when it comes to Earth's evolutionary history: pollen grains are usually no larger than 20 micrometers, or 0.02 millimeters. Using these ...
