S1 — Medicago truncatula
Summary
MTR_6G005040 (MtOLE2, also known as S1) encodes an oleosin protein that localizes to the oil body, membrane, and nucleus, with mRNA binding activity. This barrel medic gene is associated with seed oil body biogenesis, lipid storage, seed maturation, and development, as well as embryogenesis, reproductive structure development, and post-embryonic development. It is linked to chlorophyll breakdown, oxylipin metabolism, nitrogen fixation, immune response, secretion, and response to freezing. Associations include chlorophyll content, freezing tolerance, lipid accumulation, and germination traits, with observed phenotypes of enlarged oil bodies, reduced freezing tolerance, and impaired germination. Related genes in other species link the oleosin family to seed weight, germination rate, seed dormancy, low temperature stress response, and floral organ identity.
