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 ...

Global Ecology and Biogeography, Vol. 17, No. 1 (Jan., 2008), pp. 50-58 (9 pages) Aim: Local communities are subject to spatiotemporal contingencies of landscape processes; community assembly is thus ...

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.

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 ...

Incompatibility is a common means of controlling breeding behaviour among plants, and has been an important factor in evolution. It acts to prevent self-fertilization, as well as to prevent ...

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 ...

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 ...
