HAE — Brassica napus

Summary

BnHAE (DARMORV10_A06P06820.1) on chromosome A06 of oilseed rape encodes a protein with multiple zinc-finger domains (NFXL1, PHD, RING) and is annotated with diverse molecular functions including cycloeucalenol cycloisomerase, ATP:sulfate adenylyltransferase, peptide hormone binding, ammonium channel, and transmembrane receptor protein tyrosine kinase activities. The gene is associated with embryonic meristem development, radial axis specification, secondary thickening, lateral root branching, phloem loading, and photosynthesis-related processes. It localizes to endocytic vesicles, thylakoid membranes, and plastid stroma. BnHAE is linked to numerous agronomic traits including floral organ size, root number, sucrose and starch content, oleic acid content, plant male sterility, nitrate uptake, and photosynthetic ability. Related genes in other species connect BnHAE to organ abscission, vascular development, meristem function, cold tolerance, and seed longevity.
