Phosphate (Pi) availability is essential for plant growth and plant performance and often a limiting factor in nature. Here, we summarize how Pi is taken up by the roots and further distributed within the plant. These processes are strongly influenced by root-colonizing beneficial fungi, like arbuscular mycorrhizal fungi or beneficial endosymbionts. Their association with roots manipulates the hormone balance within the roots and transport processes of nutrients. Low Pi availability forces the plants to respond to this stress and ion limitation by reprogramming their gene expression pattern and root developmental strategies. Crucial players in his scenario are WRKY transcription factors. We propose that we can learn from the response of the plants to beneficial root-colonizing microbes growing under Pi limitations by identifying components which optimize root and plant development. This could be important for improving crop yields in agriculture, especially under Pi limitation conditions.
