of the 400million-year-old Rhynie Chert fossil sitein Scotland, demonstrating a link with mycorrhizal fungi that goes back to the dawn of the land flora.These tiny, shallow rooting systems were adequate for small plants (30-50 centimeters tall), but larger organisms required something more ...
an enormous variety of rooting structures had evolved.The evolution of large erect plants, and in particular trees,placed increasing demands upon the anchoring and supply functions of roots.These problems were solved mainly through the development of more extensive underground systems.The evolution of t...

Much of the evidence for the evolution of vascular plants comes from the Old Red Sandstone of South Wales and the Welsh Borderland. Plants with large rooting systems evolved during the Middle Devonian and resulted in an increase in chemical weathering of silicate rocks. This, in turn, caused a...
Background and Aims The evolution of complex rooting systems during the Devonian had significant impacts on global terrestrial ecosystems and the evolution of plant body plans. However, detailed understanding of the pathways of root evolution and the architecture of early rooting systems is currently la...
linked to the origin of a multicellular sporophytic phase. Land plants have evolved complex body plans in a way that overall complexity increased toward the tip of the land plant tree of life. Early forms were unbranched, with terminal sporangia and simple rhizoid rooting structures but without...
plant kingdoms as sexual reproduction itself and an accumulating body of genetic data reveals interesting similarities, as well as dissimilarities, between organisms with XY or ZW sex-determination systems. Therefore, I discuss how patterns and processes associated with sex linkage in male- and female...
