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 ...

Angiosperms (flowering plants) are the most diverse of all major lineages of land plants and the dominant autotrophs in most terrestrial ecosystems. Their evolutionary and ecological appearance is ...

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 ...

Plant sexuality deals with the wide variety of sexual reproduction systems found across the plant kingdom. This article describes morphological aspects of sexual reproduction of plants. That plants ...

A collaborative research group has succeeded in identifying an important transcription factor, GCAM1, which allows liverwort plants to asexually reproduce through creating clonal progenies (vegetative ...

Sex in the garden is more straightforward for the birds and the bees than it’s for the plants. Reproductive processes vary among flowering plants; for many, there is more than one option. When ...

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 ...

Self-incompatibility (SI) is a sophisticated reproductive strategy that prevents self-fertilisation and maintains genetic variability in flowering plants. This mechanism involves highly specific ...
