Root membrane ubiquitinome under short-term osmotic stress

N. Berger, V. Demolombe, S. Hem, V. Rofidal, L. Steinmann, G. Krouk, A. Crabos, P. Nacry, L. Verdoucq, V. Santoni

This study identifies 719 ubiquitinated lysine residues in Arabidopsis root membrane proteins under short-term osmotic stress, revealing a role for ubiquitination in protein internalization and growth regulation.

Uptake of Fe-fraxetin complexes, an IRT1 independent strategy for iron acquisition in Arabidopsis thaliana.

K. ROBE, m. STASSEN, j. CHAMIEH, p. GONZALEZ, s. HEM, V. SANTONI, c. DUBOS, e. IZQUIERDO ALEGRE

This study shows that fraxetin improves iron nutrition in Arabidopsis thaliana at high pH by directly transporting Fe(III) into roots, bypassing the FRO2/IRT1 system.

Differential contribution of two organelles of endosymbiotic origin to iron-sulfur cluster synthesis and overall fitness in Toxoplasma

S. Pamukcu, A. Cerutti, Y. Bordat, S. Hem, V. Rofidal, S. Besteiro

This study compares the effects of disrupting two Fe-S cluster synthesis pathways in Toxoplasma gondii, showing that plastidic disruption leads to organelle loss and death, while mitochondrial disruption triggers stress resistance.

NRT2.1 phosphorylation prevents root high affinity nitrate uptake activity in Arabidopsis thaliana

A. Jacquot, V. Chaput, A. Mauries, Z. Li, P. Tillard, C. Fizames, P. Bonillo, F. Bellegarde, E. Laugier, V. Santoni, S. Hem, A. Martin, A. Gojon, W. Schulze, L. Lejay

The paper identifies a phosphorylation site in NRT2.1 that inactivates its nitrate uptake function in Arabidopsis thaliana, revealing a regulatory mechanism modulated by nitrate.
