IPT3 — Brassica oleracea var. botrytis

Summary

BoIPT3 (BOLND125_C08P049570.1) on cauliflower chromosome 8 encodes a dimethylallyltransferase with tRNA dimethylallyltransferase, AMP dimethylallyltransferase, and ADP/ATP dimethylallyltransferase activities, and ATP binding. The protein localises to plastids, mitochondria, and the nucleus. It is associated with cytokinin and isopentenyl adenine anabolism, as well as tRNA modification. This gene has been linked to seed size, root system architecture, lateral root initiation, high light stress tolerance, plant growth, lateral branching, plant height, cell proliferation, root thickening, and trichome development. Related genes in other species are associated with cytokinin and trans-zeatin biosynthesis, nitrogen metabolism, root growth, shoot meristem size, cambial activity, seed abortion with larger surviving seeds, and growth enhancement under elevated CO₂.
