Ecophysiology of Arbuscular Mycorrhizas in Cotton

摘要: All the time! Healthy cotton plants growing in soil are always part of a mycorrhiza. A mycorrhiza is symbiosis; complex interaction that involves structural and physiological integration plant one or more species fungus. The symbiosis based upon an exchange nutrients carbohydrates that, on balance, mutually beneficial to both host fungal symbiont(s). supplies mycorrhizal fungi (a substantial sink) return transfer mineral elements plant. At macroscopic level may result dramatic changes morphology (Fig. 19-1). ultrastructural roots develop specialised interface for nutrients. molecular metabolism physiology symbionts modified. In effect, dual (or multiple) organism whose component differ functionally physically from their isolated states.
