A 100-million-year old piece of amber has been discovered which reveals the oldest evidence of sexual reproduction in a flowering plant -- a cluster of 18 tiny flowers from the Cretaceous Period -- ...
Flowering plants, or angiosperms, are a clade of seed-producing vascular plants characterized by flowers, enclosed ovules, and fruits that develop from ovaries. They exhibit double fertilization, ...
Sequencing of the water lily’s genome has shed light on the early evolution of angiosperms, flowering plants. Utilizing high-throughput next-generation sequencing technology, an international team of ...
Fossils of angiosperms first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, early angiosperms must have been weedy, fast-growing ...
Self-incompatibility (SI) is a sophisticated reproductive strategy that prevents self-fertilisation and maintains genetic variability in flowering plants. This mechanism involves highly specific ...
This video segment adapted from NOVA explains how flowers play a central role in the reproductive cycle of plants. Their striking array of colors, patterns, fragrances, and nectar all require lots of ...
In the flowering plant world, reproduction means an intricate succession of events. It begins when a pollen grain that carries the sperm cells lands on the top of the pistil, the female reproductive ...
