N2 - Phosphorus (P) availability is a limiting factor for plant growth and development. Root tip contact with low Pi media triggers diverse changes in the root architecture of Arabidopsis thaliana. The most conspicuous among these modifications is the inhibition of root growth, which is triggered by a shift from an indeterminate to a determinate root growth program. This phenomenon takes place in the root tip and involves a reduction in cell elongation, a decrease in cell proliferation, and the induction of premature cell differentiation, resulting in meristem exhaustion. Here, we review recent findings in the root response of A. thaliana to low Pi availability and discuss the cellular and genetic basis of the inhibition of root growth in Pi-deprived seedlings.
