Review: Tackling plant phosphate starvation by the roots (Devel. Cell)

The root is remarkably responsive to nutrient status of both the local environment and the whole plant. These external and internal factors affect the expression of transporters, interactions with mycorrhizal symbionts and also the overall pattern of growth and development of the root system. In this new review, Crombez et al. review how low P leads to all of these responses. They integrate our understanding of the roles of hormones and signals into a spatial and developmental model of the root, and describe the important contributions of lateral roots and the root cap in P uptake.
