This paper shows that the CopRS two-component system in Pseudomonas aeruginosa uses a phosphatase mechanism to maintain low free copper levels in the periplasm by blocking phosphorylation when copper is present.

This study shows that the Medicago truncatula YSL3 gene is essential for nitrogen fixation in root nodules by facilitating iron and zinc transport.

This study shows that MtNAS2 is essential for iron delivery in Medicago truncatula nodules, supporting symbiotic nitrogen fixation.
