PER1 — Zea mays

Summary

ZM00001EB130940 (PER1) on maize chromosome 3 encodes a secretory haem peroxidase with lactoperoxidase and peroxidase activity, classified under EC 1.11.1.7. The gene is associated with reactive oxygen species homeostasis, including the generation and removal of superoxide radicals, and with root gravitropism, root angle formation, and responses to abiotic stimuli and stresses. It is linked to vacuolar, plant-type cell wall and extracellular localisation. Associations with agronomically important traits include stem fresh and dry weight, leaf moisture content, leaf area duration, leaf senescence rate, kernel number per ear, cob length and weight, grain moisture content, carotene content, mycotoxin content, drought recovery, chilling stress response, germination ratio, and dry matter digestibility. Studies of related genes in other species link the family to similar stress and developmental processes.
