SUNN — Medicago truncatula

Summary

MTR_5G014720, also known as SUNN, encodes a transmembrane receptor serine/threonine kinase belonging to the plant LRR-RLK family. In barrel medic, this gene is associated with nitrogen fixation, meristem development, floral organ development and organogenesis, as well as responses to nitrate and nutrient levels. It has been linked to auxin transport, cytokinin anabolism, actin depolymerization, stomatal complex morphogenesis, and appressorium formation. Associations with agronomic traits include nitrogen content, phosphorus uptake, root length, and lateral root length. The gene product localizes to the plasma membrane and extracellular region. Studies of related genes in other species connect the family to additional roles in meristem size regulation and autoregulation of nodulation.
