AMPD — Beta vulgaris subsp. vulgaris

Summary

BvAMPD (BVRB_5G102910) on sugar beet chromosome 5 encodes a protein with A/AMP_deam_AS and Metal_Hydrolase domains and AMP deaminase activity, and is associated with identical protein binding, histidine kinase binding, and metal binding. The gene is associated with AMP metabolism, IMP anabolism and salvage, fructose metabolism, poly(A)+ mRNA-nucleus export, protein destabilization, ER-to-Golgi transport, downregulation of defense response, ethene-mediated signaling, pollen germination and tube growth, cell division, root and embryo development, and signal transduction. It localizes to the mitochondrial outer membrane, nuclear envelope, ER membrane, spindle, nucleolus, cytosolic ribosome, and plant-type cell wall. Associations include seed longevity, ethylene sensitivity, oxidative stress response, disease tolerance, plant growth and development, and phenotypes such as embryonic lethal, ethylene-hypersensitive hypocotyls, reduced pollen transmission, dwarf plants with curled leaves, and enhanced disease resistance.
