SPDSYN — Medicago truncatula

Summary

MTR_3G078190 (SPDSYN) on chromosome 3 of barrel medic (Medicago truncatula) encodes a protein with spermidine synthase activity that belongs to the spermidine synthase and PABS domain families. The gene is associated with polyamine metabolism, specifically putrescine and spermidine anabolism, as well as nucleus organization, response to desiccation, DNA damage response, stress response, and defense response. The encoded protein is localized to the cytosol. Studies of related genes in other species link the spermidine synthase family to the same enzyme class (EC 2.5.1.16).
