POD — Triticum aestivum

Summary

TRAESCS7A02G474200, designated TaPOD-7A, encodes a secretory haem peroxidase (EC 1.11.1.7) with lactoperoxidase and peroxidase activities, heme binding, and metal binding. This bread wheat gene on chromosome 7A is associated with hydrogen peroxide catabolism, the metabolic burst, response to oxidative stress, and circadian regulation of gene expression. TaPOD-7A is associated with numerous agronomic traits including flour color, spike length, anther length, root number and length, seed germination and germination rate, chlorophyll content, and shoot dry weight. It is also linked to stress tolerance traits such as salinity tolerance, drought tolerance, heat tolerance, and stripe rust resistance, as well as phosphorus concentration and proline content. The encoded protein localises to the vacuole, plant-type cell wall, and extracellular space. Related genes in other species are linked to root weight and leaf relative water content.
