From: A mechanistic framework for auxin dependent Arabidopsis root hair elongation to low external phosphate

Model for root hair elongation under low P. Low P elevates IAA levels in the root apex facilitated by TAA1 mediated auxin synthesis and AUX1 dependent auxin transport. The resulting increase in IAA levels leads to the induction of ARF19 in the root apex resulting in RSL2 and RSL4 induction in the elongation and differentiation zones, respectively, promoting root hair elongation
