Abstract excerpt

BACKGROUND: The availability of potassium is one of the main environmental factors for modifying the plasticity of root architecture. Many potassium channels and transporters are involved in regulating primary root growth in response to low potassium stress. NRT1.5/NPF7.3 transporter is a NO3-/H+ and K+/H+ cotransporter, and participates in NO3- and K+ translocation from the roots to the shoots. However, the...
