D8 — Zea mays

Summary

ZM00001EB216610 (D8) on maize chromosome 5 encodes a DELLA protein, a member of the GRAS transcription factor family, and is associated with gibberellin binding and E-box binding activities. This gene is linked to the regulation of plant organ formation timing, inflorescence phyllotactic patterning, trichome morphogenesis, and responses to light quality and magnetism. D8 has been connected to numerous agronomic traits including leaf length-to-width ratio, root width, flower number and diameter, fruit set and ripening, seed coat hardness, endosperm storage protein content, linoleic and linolenic acid content, copper sensitivity, and shoot elongation under submergence. It is also associated with root length, salt and jasmonic acid responses, and GA homeostasis. Related genes in other species link the family to grain yield, plant height, dwarfism, tillering, and tolerance to salt, drought, and submergence.
