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 ...

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 -- ...

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 ...

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 ...

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

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 ...

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 ...

The colonisation of land by plants was one of the most important evolutionary steps on earth; it subsequently affected all other terrestrial evolutionary processes. Leaving the aquatic environment ...

Introduction Springtime is when nature appears to come back to life after winter. Trees grow leaves, grass gets green, and flowers sprout, displaying beautiful colors and sometimes spreading a ...
