SUNN — Medicago truncatula

Summary

MTR_1G080440 (SUNN) on chromosome 1 of barrel medic encodes a protein with leucine-rich repeat (LRR) and Ser/Thr kinase domains, characteristic of plant LRR-RLKs, and is annotated with diverse molecular functions including pre-mRNA 5'-splice site binding, L-leucine binding, adenylyltransferase activity, and protein-RNA adaptor activity. The gene is associated with a wide range of biological processes, including appressorium formation, cytokinin anabolism, response to nutrient, regulation of phytochrome signaling, and upregulation of photosynthesis and lateral root development. It is linked to numerous traits such as grain yield, inflorescence number, leaf area, nitrogen content, phosphorus response, and sensitivity to UV-A light, far red light, copper, and glyphosate. The gene is also connected to phenotypes including seed longevity, salinity stress tolerance, seed development, cell wall integrity, and root system morphology.
