PP1 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G037490, also known as TtPP1, encodes a protein serine/threonine phosphatase catalytic subunit belonging to the PP1 family on durum wheat chromosome 7A. The product exhibits protein serine/threonine phosphatase activity and is annotated with phosphatase inhibitor activity, auxin efflux transporter activity, and transcription coactivator activity. TtPP1 is associated with diverse biological processes including auxin export, gibberellic acid homeostasis, red light signaling, cellular responses to abscisic acid and bacterial molecules, root hair tip growth, trichome differentiation, and regulation of epidermal cell division. The gene has been linked to numerous agronomic traits such as seed set percent, bacterial blight disease resistance, temperature stress response, plant male sterility, aluminum response, root morphology, leaf and shoot development traits, and gibberellin biosynthesis. Related genes in other species are linked to ABA signaling, root hair growth, and systemic acquired resistance.
