SS5 — Medicago truncatula

Summary

MTR_7G037650 (MtSS5, also known as SS5 or CERK1) on barrel medic chromosome 7 encodes a protein with a NAD(P)-binding domain superfamily and multiple annotated enzymatic activities, including enoyl-[acyl-carrier-protein] reductase (NADH) activity, starch synthase activity, NAD-L-malate dehydrogenase activity, and protein kinase activity. The gene is associated with starch and amylopectin anabolism, oxaloacetate and malate metabolism, the TCA cycle, fatty acid anabolism, strigolactone anabolism, and NAD metabolism. It is linked to endosperm and lateral root development, nodulation, response to symbiotic bacteria, innate immune response signaling, cell death, and virus-induced PTGS. The product localizes to the amyloplast, mitochondria, plasma membrane, vacuolar lumen, and cytoplasm. Related genes in other species are linked to starch granule initiation and number.
