CYS6 — Glycine max

Summary

GmCYS6 (GLYMA_15G227500V4) encodes a cystatin family protein with cysteine-type endopeptidase inhibitor activity, DNA and RNA endonuclease activity, DNA binding transcription factor activity, and co-ion binding. It is associated with nitrogen fixation, nodulation, seed development, plant ovule development, regulation of programmed cell death, response to oxidative stress, response to light stimulus, and drought tolerance. The gene is linked to numerous agronomic traits including seed size, plant height, flowering time, germination rate, leaf senescence, root development, and responses to high and low temperature stress. It is associated with brassinosteroid content and sensitivity, carotenoid and anthocyanin content, total soluble sugar content, and fruit quality. The protein localizes to the endoplasmic reticulum, cytosol, nucleus, and extracellular space. Studies of related genes in other species link the family to cold and salt tolerance, seed germination, carotenoid accumulation, and floral transition.
