Role of Mycorrhizae in Agriculture
Mycorrhizas are mutualistic relationships formed by soil fungus and plant roots. Almost all plant species benefit from advantageous relationships formed by specialised root-inhabiting fungus. These fungi infiltrate feeder root tissues and generate modified roots known as mycorrhizae (fungus roots), which considerably improve nutrient and water absorption efficiency. In natural soils, most plants require mycorrhizae for normal growth and development. Members of the fungal kingdom (Zygomycetes, Ascomycetes, and Basidiomycetes) and most vascular plants are partners in this interaction. Arbuscular and ectomycorrhizae are the most frequent and ubiquitous of the seven varieties of mycorrhizae (arbuscular, ecto, ectendo, arbutoid, monotropoid, ericoid, orchidaceous mycorrhizae). Ectomycorrhizas : The hyphae of ectomycorrhizal fungi do not penetrate individual root cells in ectomycorrhizas. Ectomycorrhizas consist of a hyphal membrane, or mantle, that covers the root tip and a Hart...
