WRKY23 — Glycine max

Summary

GmWRKY23 (GLYMA_03G220800V4) on soybean chromosome 3 encodes a WRKY transcription factor of the IIc subfamily, possessing sequence-specific DNA-binding and promoter-specific chromatin-binding activities, and localizes to the nucleus. It is associated with positive regulation of transcription initiation, nutrient storage, auxin polar transport, and hormone anabolism including gibberellin and abscisic acid metabolism linked to stomatal movement. The gene has been connected to isoflavonoid and glutathione metabolism, cellular detoxification, and responses to aluminum, cadmium, bacterial molecules, and nematodes. Agronomically, it is linked to leaf chlorophyll content, plant height, germination rate, and salt tolerance. Phenotypic associations include embryo development, shoot regeneration, root growth, vascular tissue development, and nematode resistance. Studies of related genes in other species further connect the family to drought tolerance and shoot branching.
