Scientific background . Glutaredoxins (GRXs) are enzymes that catalyze the reduction of glutathionylated proteins and disulfide bonds, or participate in the maturation of iron–sulfur proteins (Berndt et al., 2021; Rouhier et al., 2008). Through these activities, some GRXs maintain cellular redox homeostasis, whereas others regulate gene expression or modulate signaling pathways associated with developmental processes (Couturier et al., 2015; El Baidouri et al., 2024). Plant GRXs are divided into four classes. While research has focused primarily on classes I, II and III, the functions of class IV GRXs (GRX-IVs) remain largely unexplored. However, recent transcriptomic data from poplars inoculated with different fungi have revealed that a gene encoding one of the three poplar GRX-IVs (PotriGRXC16.1) is specifically induced in roots during the early stages of mycorrhiza development (Marqués-Gálvez et al., 2025). These findings suggest a potential role for PotriGRXC16.1 in the establishment of mycorrhizal symbiosis. In addition to their canonical GRX domain
