Abstract
As decomposers or plant pathogens, fungi deploy invasive growth and powerful carbohydrate active enzymes to reduce multicellular plant tissues to humus and simple sugars. Fungi are perhaps also the most important mutualistic symbionts in modern ecosystems, transporting poorly soluble mineral nutrients to plants and thus enhancing the growth of vegetation. However, at their origin over a billion years ago, fungi, like plants and animals, were unicellular marine microbes. Like the other multicellular kingdoms, Fungi evolved increased size, complexity, and metabolic functioning. Interactions of fungi with plants changed terrestrial ecology and geology and modified the Earth's atmosphere. In this review, we discuss the diversification and ecological roles of the fungi over their first 600 million years, from their origin through their colonization of land, drawing on phylogenomic evidence for their relationships and metabolic capabilities and on molecular dating, fossils, and modeling of Earth's paleoclimate.
