SPL2 — Medicago truncatula

Summary

MTR_8G020850 (MtSPL2) on chromosome 8 of barrel medic encodes a protein with ubiquitin-protein transferase activity, belonging to the SPL2-like, MUL1-like, and Znf_RING domain families. The gene is associated with organelle organization, cell motility, the mevalonate pathway, regulation of flavonoid anabolism, indole alkaloid, sterol, jasmonic acid, and saponin anabolism, protein breakdown, lipid transport, the ERAD pathway, organ growth, organogenesis, nitrogen fixation, detoxification, and seed development. It is linked to chloroplast envelope and mitochondrial localization. Associations include leaf size, somatic embryogenesis, juvenile-to-adult and vegetative-to-reproductive transitions, age-related resistance, adventitious root development, floral organ and silique development, and plant fertility. Studies of related genes in other species link the family to adventitious root number, silique morphology, and meristem identity.
