PP1 — Triticum turgidum subsp. durum

Summary

TRITD3AV1G107730, also known as TtPP1, encodes a protein serine/threonine phosphatase catalytic subunit belonging to the PP1 family on durum wheat chromosome 3A. The product possesses protein serine/threonine phosphatase activity and is associated with protein phosphatase type 1 complexes. This gene is linked to diverse biological processes including auxin export, leaf and cotyledon morphogenesis, trichome differentiation, root hair tip growth, and responses to abscisic acid, chitin, and red light. Associations with agronomically relevant traits include bacterial blight disease resistance, seed set percent, plant male sterility, temperature stress response, shoot system elongation, and whole plant size. The gene is also connected to phenotypes such as root hair density and length, lateral root development, auxin transport and distribution, phyllotaxis, and shoot apical meristem size.
