PHD2 — Brassica oleracea var. botrytis

Summary

BoPHD2 (BOLND125_C09P064360.1_BOLND125_V1) on cauliflower chromosome 9 encodes a protein with PHD-finger and SPOC domains that acts as a histone reader with histone- and protein-binding activity. The gene is associated with detection of hypoxia, negative regulation of RNA polymerase II transcription elongation, epigenetic downregulation of gene expression, and regulation of photoperiodic flowering. Its product localises to the nucleus. BoPHD2 has been associated with transcriptional repression. Studies of related genes in other species link the PHD2 family to early flowering under long-day conditions and to dwarfism with small leaves and poor fertility, as well as to photochemical quenching.
