HAE — Brassica napus

Summary

BnHAE (DARMORV10_C05P08310.1) on chromosome C05 of oilseed rape encodes a protein with multiple zinc-finger domains (NFX1-family, PHD-finger, RING) and is associated with diverse molecular functions including peptide hormone binding, transmembrane receptor protein tyrosine kinase activity, chlorophyll binding, and cycloeucalenol cycloisomerase activity. This gene is linked to embryonic meristem development, radial axis specification, secondary thickening, phloem loading, and lateral root branching. Associations with agronomic traits include floral organ size, root number, sucrose and starch content, oleic acid content, photosynthetic ability, plant male sterility, nitrate uptake, and cytokinin content. It has also been connected to floral organ abscission, phloem differentiation, cold tolerance, seed longevity, and vascular development. Studies of related genes in other species link the family to meristem development, organ abscission, and stress responses.
