GCT — Triticum aestivum

Summary

TRAESCS2D02G494900, designated TaGCT (also known as TaMAB2 or TaMED13-2D) on bread wheat chromosome 2D, encodes a subunit of the Mediator complex, a transcriptional co-regulator with transcription coactivator activity and protein-binding capacity. The gene is associated with regulation of radial pattern formation, temporal development, embryogenesis, and positive regulation of RNA polymerase II transcription. It is associated with wheat stripe rust disease response, plant growth and development traits, and phenotypes including juvenile-to-adult transition, embryo patterning, auxin response, root hair development, and lipid biosynthesis. Localised to the nucleus and Mediator complex, TaGCT is also associated with cell cycle processes including G1/S transition and mitosis. Related genes in other species are linked to flowering time, germination, vegetative phase change, and root architecture.
