Plant root hairs elongate in response to low soil phosphate. Here Bhosale et al. show that root hair elongation requires auxin synthesis mediated by TAA1, auxin transport by AUX1 in the lateral root cap and epidermis, and signaling via the auxin-inducible ARF19, RSL2 and RSL4 transcription factors.
