PA2 — Triticum aestivum

Summary

TRAESCS4D02G234200 (symbol PA2, also known as POD, TaPRX37, and TaPRX53) on wheat chromosome 4D encodes a secretory peroxidase with peroxidase activity, lactoperoxidase activity, heme binding, and metal binding. This gene is associated with hydrogen peroxide catabolic processes, response to oxidative stress, and the TCA cycle, and localizes to the vacuole, plant-type cell wall, and extracellular space. The gene has been linked to agronomically important traits including grain weight, spike length, spikelet length, anther length, leaf chlorophyll content, starch content, anthocyanin content, root weight, seed germination, germination rate, salinity tolerance, drought tolerance, and stripe rust resistance. It also connects to signaling pathways involving jasmonic acid, gibberellin, salicylic acid, and cold temperature response, and shows associations with transcription factors such as MYB80, DERF2, and WRKY46.
