Bt2 — Zea mays

Summary

ZM00001EB425100, symbol Bt2, is a maize gene on chromosome 10 that encodes a BTB/POZ domain and TAZ zinc finger domain-containing protein, belonging to the BT1/2/3/4/5 family. The product binds calmodulin and zinc, and is localized to the nucleus. Bt2 is associated with starch biosynthesis, accumulation, and metabolism in the endosperm, and with seed weight, grain weight, grain yield, and kernel wrinkling. It is also linked to plant architecture, leaf angle, plastochron, grain lysine and protein content, amylopectin content, and etched endosperm. The gene is associated with responses to hormones, hydrogen peroxide, and salicylate, as well as nitric oxide storage and regulation of transcription.
