AP2 — Triticum turgidum subsp. durum

Summary

TRITD3BV1G010910 (TtAP2) encodes a DNA-binding transcription factor belonging to the AP2/ERF ERF subfamily, localised to the nucleus. In durum wheat, this gene is associated with meristem development, morphogenesis, response to abiotic stimulus, and homeostasis. It has been linked to several agronomically important traits, including spike density, grains per spike, spike length, anthesis time, plant height, and grain yield. Studies of related genes in other species connect the AP2/ERF family to additional traits such as seed length, panicle weight, spikelet number, grain weight per spike, and anther extrusion, though these associations are not yet established in durum wheat.
