NIM1 — Glycine max

Summary

GLYMA_09G064700V4, designated GmNIM1, encodes a member of the NPR1/NIM1-like protein family characterized by ankyrin repeats and a central NPR domain. The product possesses salicylic acid binding, oxidoreductase, calmodulin binding, and DNA-binding transcription factor activities. In soybean, GmNIM1 is associated with regulation of systemic acquired resistance, defense responses to bacteria, insects, and herbivores, as well as salicylic acid and jasmonic acid signaling pathways. It is linked to responses to microbial phytotoxins, xenobiotic stimuli, and reactive oxygen species metabolism. The gene is associated with resistance to bacterial blight, Cercospora leaf spot, wheat stripe rust, and rice sheath blight, as well as drought sensitivity, hydrogen peroxide content, iron concentration, and inflorescence morphology. Studies of related genes in other species link the family to pathogen resistance, systemic acquired acclimation, and stress tolerance.
