MKD1 — Medicago truncatula

Summary

MTR_1G016300, also known as MtMKD1, encodes a dual-specificity protein kinase with MEKK activity, transmembrane receptor serine/threonine kinase activity, and additional molecular functions including steroid binding, SNARE binding, and calcium ion binding. The protein contains a Ser/Thr kinase catalytic domain and belongs to the EDR1/CTR1/ARMC3-like peptidase family. MtMKD1 is associated with nitrogen fixation, detection of symbiotic fungi, meristem development, organogenesis, regulation of photosynthesis, response to nitrate, cytokinin anabolism, MAPK cascade, cell plate assembly, and actin depolymerization. It localizes to the plasma membrane, endosome, nucleolus, and microtubule organizing center. The gene is linked to nitrogen content, phosphorus uptake, root length, and lateral root length. Related genes in other species are linked to disease resistance and reduced ABA sensitivity in root elongation and seed germination.
