NSP2 — Glycine max

Summary

GmNSP2 (GLYMA_04G251900V4) on soybean chromosome 4 encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. It is associated with nodulation, nitrogen fixation, arbuscular mycorrhizae formation, and response to symbiotic fungi, as well as root and leaf development, photomorphogenesis, cell cycle, and asymmetric cell division. The gene is linked to bundle sheath cell fate specification, radial pattern formation, geotropism, phosphate ion detection, and response to nutrients. Its product localizes to the nucleus, nuclear membrane, endoplasmic reticulum, and cytoplasm. Studies of related genes in other species connect the GRAS family to plant height and leaf size traits.
