Functional characterization of the Co2+ transporter AitP in Sinorhizobium meliloti: a new player in Fe2+ homeostasis

P. Mihelj, I. Abreu, T. E. Moreyra, M. Gonzalez-Guerrero, D. C. Raimunda

This paper investigates the role of AitP, a Co2+ transporter in Sinorhizobium meliloti, in Fe2+ homeostasis and shows it mitigates Co2+ toxicity by exporting Fe2+ and enabling heme-mediated Fe import.

Arabidopsis thaliana Zn2+-efflux ATPases HMA2 and HMA4 are required for resistance to the necrotrophic fungus Plectosphaerella cucumerina BMM

V. Escudero, A. Castro-Leon, D. Ferreira Sanchez, I. Abreu, M. Bernal, U. Kramer, D. Grolimund, M. Gonzalez-Guerrero, L. Jorda

This study shows that HMA2 and HMA4 zinc efflux ATPases in Arabidopsis are critical for resistance to the necrotrophic fungus PcBMM, with zinc accumulation and defense hormone pathways playing a key role.

Medicago truncatula Ferroportin2 mediates iron import into nodule symbiosomes

V. Escudero, I. Abreu, M. Tejada-Jimenez, E. Rosa-Nunez, J. Quintana, R. I. Prieto, C. Larue, J. Wen, J. Villanova, K. S. Mysore, J. M. Arguello, H. Castillo-Michel, J. Imperial, M. Gonzalez-Guerrero

This study shows that MtFPN2 in Medicago truncatula is essential for iron delivery to symbiosomes, supporting nitrogen fixation, but not for vascular iron transport.
