Pinus forms a mycorrhizal association where fungi help in nutrient absorption and nitrogen fixation.

Mycorrhiza is a symbiotic association between fungi and the roots of higher plants. Fungi may also live symbiotically with algae, forming lichens.

Arbuscules denote finely branched intracellular haustorial structures formed by glomeromycotan mycorrhizal fungi within root cortical cells of vascular plants including most crops. Arbuscule branches massively increase interfacial surface area for bidirectional nutrient exchange: fungus delivers phosphate and micronutrients absorbed from soil via extraradical hyphae to plant, plant supplies photosynthate carbohydrates and lipids to obligate fungal symbiont. Formed during arbuscular mycorrhizal symbiosis oldest and most widespread mutualism dating ~400 million years. Not associated with parasit

Mycorrhiza is a resource-based mutualism between a fungus and a plant root. Fungal hyphae extend far beyond the root depletion zone and efficiently acquire phosphorus, nitrogen, micronutrients, and water from a larger soil volume. These resources are transferred to the plant, while the fungus receives photosynthetically fixed carbon, mainly sugars and lipids. Arbuscular mycorrhizal fungi enter root cortical cells and form branched arbuscules for exchange; ectomycorrhizal fungi form a mantle and Hartig net around root cells. The association may also improve stress tolerance or pathogen resistan
