SUS5 — Medicago truncatula

Summary

MTR_5G076830 (MtSUS5) on barrel medic chromosome 5 encodes a sucrose synthase, possessing sucrose synthase activity and belonging to the sucrose synthase family with domains including SUS_EPBD and SUS_N. This gene is associated with sucrose breakdown, carbohydrate breakdown, callose deposition in phloem sieve plates, response to anoxia, fermentation, abscisic acid anabolism, lipogenesis, seed coat development, and organogenesis. It is linked to traits such as carbohydrate content, starch content, seed size, plant height, root length, root weight, plant dry weight, leaf water potential, chlorophyll content, nitrogen content, amino acid content, and drought tolerance. The gene product localizes to the plant-type cell wall, membrane, and cytoplasm. Studies of related genes in other species link the family to EC 2.4.1.13 and associations with glucose content, cellulose content, sugar content, starch grain synthesis, and seed weight.
