In both ecological and agricultural contexts, plants often grow in soils with low soluble phosphate content. Plants respond to this 11 situation by a series of developmental and metabolic adaptations that are aimed at increasing the acquisition of this vital nutrient fromthe soil, as well as to sustain plant growth and survival. The development of a prehensive understanding of how plants sense phosphate deficiency and coordinate the responses via signaling pathways has bee of major interest, and a number of signaling players and works have begun to surface for the regulation of the phosphate deficiency response. In practice, application of such knowledge to improve plant Pi nutrition is hindered by plex crosstalks, which are emerging in the face of new data, such as the coordination of the phosphatedeficiency signaling works with those involved with hormones, photoassimilates (sugar), as well as with the homeostasis of other ions,such as iron. In this review, we focus on these crosstalks and on recent progress in discovering new signaling players involved in the Pistarvation responses, such as proteins having SPX domains.
