Symbiotic options for the conquest of land

Symbiotic options for the conquest of land | MY TOPIC | Scoop.it

The domination of the landmasses of Earth by plants starting during the Ordovician Period drastically altered the development of the biosphere and the composition of the atmosphere, with far-reaching consequences for all life ever since. It is widely thought that symbiotic soil fungi facilitated the colonization of the terrestrial environment by plants. However, recent discoveries in molecular ecology, physiology, cytology, and paleontology have brought into question the hitherto-assumed identity and biology of the fungi engaged in symbiosis with the earliest-diverging lineages of extant land plants. Here, we reconsider the existing paradigm and show that the symbiotic options available to the first plants emerging onto the land were more varied than previously thought.

EPPO Global Database is maintained by the Secretariat of the European and Mediterranean Plant Protection Organization (EPPO). This database is still under development but its ultimate goal is to include all pest-specific information that has been produced by EPPO.
