POD — Triticum aestivum

Summary

TRAESCS7D02G461200 (TaPOD) encodes a secretory haem peroxidase (EC 1.11.1.7) with lactoperoxidase and peroxidase activity, and is located in the vacuole, plant-type cell wall and extracellular space. This bread wheat gene on chromosome 7D is associated with hydrogen peroxide catabolism, the metabolic burst, response to oxidative stress, circadian regulation of gene expression, and virus-induced post-transcriptional gene silencing. TaPOD has been linked to several agronomically important traits including stripe rust resistance, heat and drought tolerance, salinity tolerance, flour colour, spike length, anther length, root number and length, shoot dry weight, chlorophyll content, proline content, germination rate, and phosphorus concentration. Studies of related peroxidases in other species connect the family to seed germination, root weight, leaf relative water content, and soluble protein content.
