When the soil holds not enough phosphorus: Scientists describe new transporter in cells of plant roots

Plants cannot survive without phosphorus. It forms the backbone of many crucial molecules (such as DNA) and is a key player in energy transfer reactions. Low availability of phosphorus is a major environmental stress for plants and can lead to great losses in crop production. But plants can't make their own phosphorus; they get all they need at the root-soil interface, in the form of inorganic phosphate (Pi), so one way to maximise the amount of phosphorus in the plant is to turn up Pi uptake by root cells....
