IQD1 — Brassica oleracea

Summary

BoIQD1, encoded by the cabbage gene BOLC102_C03P045690.1 on chromosome 3, is a member of the IQD protein family, characterized by an IQ motif and EF-hand-binding domain. The product binds microtubules, calmodulin, and other proteins, and localizes to the microtubule, nucleus, and extracellular space. In cabbage, BoIQD1 is associated with glucosinolate metabolism, defense responses, seedling development, and chewing. The gene is linked to insect herbivory resistance, resistance to Botrytis cinerea, disease resistance, and altered levels of salicylic and jasmonic acids. Studies of related genes in other species connect the family to plant defense and glucosinolate accumulation.
