Advances of Study on Arbuscular Mycorrhizal Symbiotic Phosphate Transporter in Plants / 中国生物工程杂志

ABSTRACT

The arbuscular mycorrhizal(AM)symbiosis is a mutualistic endosymbiosis formed by plant roots and AM fungi.The AM symbiosis is manifested in bidirectional nutrient exchange AM fungi obtain carbon from their plant host while assisting the plant with the acquisition of mineral nutritions(in particular phosphate)from the soil.AM symbiosis facilitate phosphate uptake is the central reason of plant growth and development.Phosphate transport into the root is mediated by phosphate transporters,and phosphate transporters play a role in the acquisition of phosphate released by the fungus in the AM symbiosis.The molecular biology of arbuscular mycorrhizal symbiotic phosphate transporters in plants was summarized.AM phosphate transporter belong to Pht1 family,is not only essential for the acquisition of phosphate,also critical to AM symbiosis.Study of phosphate transport roles and their gene regulation will further our knowledge of the interaction between the two symbiotic partners,and so as to provide innovative approach to improving phosphate efficiency and agricultural yield.
