BX1 — Zea mays

Summary

ZM00001EB165610, also known as BX1, is a maize gene on chromosome 4 that encodes a protein with indole-3-glycerol-phosphate lyase activity and tryptophan synthase activity, belonging to the Trp_synthase_alpha_AS and aldolase_TIM domain families. The gene is associated with indole alkaloid anabolism, tryptophan formation, and benzoate breakdown, as well as with larval development, oviposition, and chemotaxis. It has been linked to insect damage, leaf necrosis, drought tolerance, plant height, anthesis time, grain weight, seed protein content, and heterosis. The encoded product localises to the cytosol. Studies of related genes in other species link the family to similar defensive secondary metabolism and tryptophan biosynthesis pathways.
