SCR — Asparagus officinalis

Summary

AoSCR (SCR) on asparagus chromosome 5 encodes a GRAS family transcription factor with sequence-specific DNA binding and protein homodimerization activity. The gene is associated with bundle sheath cell fate specification, radial pattern formation, asymmetric cell division, leaf development, and cell death. It has been linked to responses to nutrients, phosphate ion detection, geotropism, arbuscular mycorrhizae formation, and response to symbiotic fungi, as well as maintenance of protein location in the nucleus and regulation of transcription by RNA polymerase II. The encoded protein localises to both the cytoplasm and nucleus. Studies of related genes in other species link the family to self-incompatibility, though this has not been established in asparagus.
