FLP — Brassica oleracea var. botrytis

Summary

BoFLP (MYB124) on cauliflower chromosome 5 encodes a MYB-domain transcription factor that binds DNA and RNA polymerase II cis-regulatory regions. It is associated with stomatal complex formation, guard mother cell division, guard cell differentiation, and regulation of stomatal complex patterning. The gene is also linked to leaf pavement cell development, regulation of cell wall organization, primary root development, lateral root development, root gravitropism, and response to gravity. Additional associations include multicellular organismal water homeostasis, shikimate and phenylpropanoid metabolism, floral organ senescence, shoot regeneration, cellular response to virus, and regulation of cell cycle G1/S phase transition. Phenotypic connections include drought tolerance, salt tolerance, and severe stomatal development defects with arrested guard cells. The protein localizes to the nucleus and plant-type cell wall. Studies of related genes in other species link the family to stomatal development, megasporogenesis, and ovule development.
