Lr34 — Triticum aestivum

Summary

TRAESCS4A02G384800, known as Lr34 or ABCG50 on wheat chromosome 4A, encodes an ABC transporter domain-containing protein with ATP hydrolase activity and ATP binding capability. This gene is associated with resistance to stem rust, leaf rust, and yellow rust, as well as leaf tip necrosis. It is linked to adult plant resistance to leaf rust and powdery mildew resistance. The encoded protein localizes to the membrane and plasmalemma and is associated with biological processes including defense response, immune response, cell death, hormone transport, and lipid metabolism. Additionally, Lr34 is associated with agronomic traits including grain yield, grain weight, plant height, heading time, harvest index, ear number, drought tolerance, and cold tolerance. Related genes in other species link the family to rice leaf blast disease response.
