It is hypothesized that terrestrial plants are the product of an ancient and continuing symbiosis of a semi-aquatic ancestral green alga and an aquatic fungus-an oomycete. The Siluro-Devonian "explosive" colonization of land, and indeed the very evolution of plants, was possible only through such mutualistic partnerships-partnerships that were equipped to cope with the problems of desiccation and starvation associated with terrestrial existence.
据推测,陆生植物是一种古老且持续共生的产物,其一方是半水生的祖先绿藻,另一方是水生真菌——一种卵菌。志留纪-泥盆纪陆地的“爆发式”殖民化,乃至植物的整个进化过程,只有通过这种互利共生关系才有可能实现,这种共生关系有能力应对与陆地生存相关的干燥和饥饿问题。
