ERS — Asparagus officinalis

Summary

A4U43_C05F14730 (ERS/AoERS) encodes a glutamyl-tRNA synthetase with glutamate-tRNA ligase activity (EC 6.1.1.17), a core component of the aa-tRNA-synth_I family that charges tRNA with glutamate. In asparagus, this gene is associated with tRNA charging, glutamyl-tRNA aminoacylation, and broader biological processes including brassinosteroid-mediated signalling, reproductive structure development, plant ovule development, and chloroplast organization. It has been linked to traits such as photosynthetic rate, nitrate uptake, leaf composition, seedling growth and development, and organ identity. The encoded protein localizes to multiple cellular compartments including the chloroplast stroma, plastid, mitochondria, cytosol, Golgi complex, and plant-type vacuole. Studies of related genes in other species connect the family to ethylene signalling, ethylene sensitivity, organ size, and ovule abortion.
