POD — Triticum aestivum

Summary

TRAESCS7B02G375600 (TaPOD, chromosome 7B) encodes a secretory haem peroxidase with lactoperoxidase and peroxidase activity, classified under EC 1.11.1.7. The gene is associated with hydrogen peroxide catabolism, the metabolic burst, response to oxidative stress, and circadian regulation of gene expression. TaPOD has been linked to vacuolar, plant-type cell wall, and extracellular localisation. Associations with agronomically important traits include flour colour, phosphorus concentration, shoot dry weight, yield, root number and length, proline content, chlorophyll content, seed germination and germination rate, as well as tolerance to salinity, drought, heat, and stripe rust. The gene is also associated with nodulation, homeostasis, and virus-induced PTGS. Studies of related genes in other species link the family to root weight and leaf relative water content.
