AB Pinus pinaster is a conifer used as a model species for the study of nitrogen (N) metabolism, alimiting and fundamental element for plant growth and development due to its presence indifferent compounds such as nitrogenous bases, nucleic acids and amino acids (Yao et al.2020). Numerous genomic and transcriptomic studies in this species have led to a betterunderstanding of nitrogen management in forest plants.In this context, it is essential to understand how organic nitrogen is mobilised betweencompartments for its assimilation, a process involving amino acid (AA) transporters. Thesetransporters include AA permeases (AAPs), cationic transporters (CATs) and UmamiTs (UsuallyMultiple Acids Move In and out Transporter) (Yang et al. 2020, Zhao et al. 2021), recentlyidentified.Our work focuses on the study of the UmamiTs family of importers/exporters in P. pinaster,which will allow us to understand their role in amino acid mobilisation, fundamental inprocesses such as embryogenesis, N remobilisation and loading and unloading in thephloem/xylem. After the identification of 26 members of the family, a phylogenetic analysiswas performed together with UmamiTs from other plant species of economic and ecologicalinterest. Expression studies reveal that they are located in different compartments at thesubcellular level and suggest that they could be involved in N transport between them,ensuring its subsequent mobilisation and storage in different tissues. Understanding the roleof UmamiT transporters in pine not only sheds light on crucial processes like nitrogenassimilation and amino acid mobilization but also holds promise for enhancing forestrypractices and optimizing plant growth in sustainable ecosystems.
