Wall ultrastructure of fossil-dispersed pollen has recently played an important role in increasing our understanding of the origin and early evolution of angiosperms. The criteria currently used to ...

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 ...
