PHR1 — Brassica napus

Summary

BnPHR1 (DARMORV10_A01P09320.1) on chromosome A01 of oilseed rape encodes a Myb_CC_LHEQLE domain-containing transcription factor with DNA binding, transcription factor activity, SUMO transferase activity, and SUMO binding. This gene is associated with phosphorus metabolism, phosphate homeostasis, and the positive regulation of cellular responses to phosphate starvation. It is linked to sulfate homeostasis, nitrate assimilation regulation, and responses to arsenite ion and high light intensity. Associations include phosphorus uptake and response, copper sensitivity, aluminum response, anthocyanin content, leaf senescence, root thickness, flowering time, seed development, disease tolerance, and abiotic stress responses including high and low temperature, oxidative stress, and salt tolerance. The gene is also associated with shoot regeneration, abaxial cell fate specification, brassinosteroid anabolism, and downregulation of systemic acquired resistance and unidimensional cell growth.
