CRL1 — Zea mays

Summary

ZmCRL1, located on maize chromosome 1, encodes a LOB domain-containing protein that acts as a DNA-binding transcription activator with protein homodimerization activity and localizes to the nucleus. The gene is associated with root morphogenesis, adventitious and primary root development, auxin polar transport and anabolism, cell wall and secondary cell wall biogenesis, lignin and phenylpropanoid anabolism, triterpenoid anabolism, flavonoid metabolism, hormone metabolism, cell cycle control, ribosome assembly and biogenesis, protein synthesis, and differential growth. It has been connected to crown root number, rootless phenotype, root number, root length, lateral root length, root dry weight, plant height, tiller number, grain number per plant, grain yield per plant, seed viability, seed maturation, heterosis, phosphorus content, lignin content, protein content, and ethylene sensitivity. Related genes in other species link the family to crown root development, adventitious root initiation, auxin and cytokinin responses, and defense.
