AL1 — Brassica oleracea

Summary

BoAL1, located on cabbage chromosome 9, encodes a transcriptional co-regulator with histone-binding, DNA-binding, and zinc-binding activities, belonging to the Alfin-like protein family characterized by PHD zinc-finger domains. In cabbage, BoAL1 is associated with maintenance of inflorescence, floral, and shoot apical meristem identity, cell fate determination, root hair elongation, root development, chromatin organization, cellular responses to phosphate starvation and salinity, and epigenetic downregulation of gene expression. The gene is linked to flowering time, seed germination and dormancy, seed thermoinhibition, hypocotyl elongation, root morphology, carpel morphology, vegetative-to-reproductive phase transition, and responses to abscisic acid and jasmonic acid. BoAL1 localizes to the nucleus, cytoplasm, mitochondria, and PRC1 complex. Related genes in other species are linked to phosphate homeostasis and root hair formation.
