R1 — Zea mays

Summary

ZM00001EB398390, the maize R1 gene on chromosome 9, encodes an alpha-glucan water dikinase-like N-terminal Ig-like domain-containing protein with annotated a-glucan, water dikinase activity, histidine kinase activity, metal binding, and ATP binding. The gene is associated with starch breakdown, pigmentation, and RNA modification processes. R1 is linked to anthocyanin pigmentation, kernel colour, grain color, plant color, and anthocyanin content traits. Studies of related sequences in other species connect the family to the enzyme classes 2.7.9.4 and 2.7.13.3.
