WOX5 — Triticum turgidum subsp. durum

Summary

TRITD3AV1G222700 (symbol WOX5, also known as TtWOX5A or TtWOX5B) on durum wheat chromosome 3A encodes a homeobox domain-containing protein belonging to the WUSCHEL-like family. The gene is associated with root development in this species and has been linked to numerous processes including axillary shoot meristem initiation, plant organ formation, procambium histogenesis, regeneration, embryo shoot apical meristem specification, and gibberellic acid homeostasis. It is also associated with traits such as shoot meristem development, root morphology, plant height, flowering time, seed set, lignin content, and responses to abiotic stress, low temperature, and oomycetes. Studies of related genes in other species link the WOX5 family to root emergence, panicle development, salt tolerance, and seed coat development.
