摘要

With the support by the National Natural Science Foundation of China,the research team led by Prof.Yi KeKe (易可可) at the Key Laboratory of Plant Nutrition and Fertilizer,Institute of Agricultura Resources and Regional Planning,Chinese Academy of Agricultural Sciences,identified the vacuolar phosphate efflux transporters in land plants,which was published in Nature Plants (2019,5:84-94). Phosphorus is an essential macronutrient for plant growth and development.Phosphate (Pi) is the major form of phosphorus that can be easily used by plants.However,the amount of Pi in the soil that is available to the plant is often limiting for growth.Plants have evolved different strategies to adapt to changes in Pi availability,including efficient Pi storage/remobilization machineries.After being absorbed by plant roots,most of the Pi is stored in vacuole.This vacuolar reservoir is used to buffer Pi changes in the cytoplasm in response to changes in metabolic demand and Pi availability in soil.However,the mechanism of release of vacuolar Pi store to cytoplasm in plants is still unknown.In the issue of Nature Plants,Yi's group reported the identification of vacuolar Pi efflux transporters (OsVPE) in land plants.
