CRT1 — Glycine max

Summary

GLYMA_20G098400V4, designated GmCRT1, encodes a calreticulin/calnexin family protein with calcium ion binding, sugar binding, and histidine kinase activity, and is associated with ethylene receptor activity and disulphide bond formation. Localised to the endoplasmic reticulum, ER lumen, and membrane, as well as the apoplast, chloroplast stroma, and plasmodesmata, GmCRT1 is linked to diverse biological processes including ethylene and jasmonic acid signalling, seed dormancy, seedling development, flooding and water stress responses, and the ERAD pathway. The gene has been connected to agronomically important traits such as yield, seed yield, root length and thickness, leaf morphology, stomatal resistance and opening, and responses to temperature stress, oxidative stress, aphids, and viral disease. Studies of related genes in other species link the family to endoplasmic reticulum stress tolerance, ethylene sensing, and resistance to turnip crinkle virus.
