CRL1 — Zea mays

Summary

ZM00001EB442790, designated CRL1 (Crown Rootless 1) in maize, encodes a LOB domain-containing protein with DNA-binding transcription activator activity and protein homodimerization activity, and localizes to the nucleus. The gene is associated with adventitious and primary root development, root morphogenesis, auxin polar transport and anabolism, cell wall biogenesis, secondary cell wall and lignin anabolism, phenylpropanoid and triterpenoid anabolism, flavonoid metabolism, hormone metabolism, cell cycle control, ribosome assembly and biogenesis, and protein synthesis. CRL1 is linked to crown root number, root number and dry weight, lateral root length, plant height, tiller number, grain number and yield per plant, seed viability and maturation, phosphorus content, lignin content, protein content, heterosis, and ethylene sensitivity. Related genes in other species are linked to auxin and cytokinin responses, crown root and adventitious root development, and defense.
