BP — Arabidopsis thaliana

Summary

AT4G08150 (BP, also known as KNAT1) encodes a KNOTTED-like homeobox protein containing KNOX1, KNOX2, ELK and homeobox domains, and is annotated with DNA-binding transcription factor activity, chromatin binding, miRNA binding and translation initiation factor activity. In Arabidopsis, BP is associated with shoot meristem maintenance, organ boundary specification, secondary thickening, gibberellin biosynthesis regulation, and miRNA transcription and processing. The gene is linked to numerous traits including pedicel length, stem thickness, leaf shattering, lignin biosynthesis, floral organ number, seed viability, plant size, and responses to boron sensitivity and biotic stress. BP localises to the nucleus, cytoplasm, plastid and plasmodesmata. Studies of related genes in other species connect the family to leaflet number, lignin content and anthocyanin content.
