Phosphorus Acquisition and Utilization in Plants

Hans Lambers

Summary: Significant progress has been made on plant phosphorus nutrition at the molecular level, but there is a need to integrate information from various disciplines. Strategies to mobilize phosphorus in low-P soil are found to be more effective than mycorrhizal strategies. Understanding the trade-offs of different investment patterns in phosphorus fractions is crucial for optimizing plant growth.

Recent insights into the metabolic adaptations of phosphorus-deprived plants

D. M. S. B. Dissanayaka et al.

Summary: Plants have evolved adaptive metabolic processes in response to phosphorus deficiency, enhancing their efficiency in phosphorus acquisition and utilization through changes in gene expression, post-transcriptional, and post-translational mechanisms. These responses include up-regulation of high-affinity phosphorus transporters and scavenging enzymes, membrane remodeling, and flexibility in plant metabolism and bioenergetics. These advances are leading to the development of innovative strategies for engineering phosphorus-efficient crops to ensure long-term food security and ecosystem preservation.

Intracellular phosphate sensing and regulation of phosphate transport systems in plants

Zhengrui Wang et al.

Summary: Recent research has shown that inositol pyrophosphates act as phosphate signaling molecules, perceived by the SPX domains in eukaryotic cells to regulate Pi transport and signaling. The PP-InsP-SPX signaling module is evolutionarily conserved and extensively utilized in plant systems for Pi transport and signaling.
