HAE — Brassica juncea

Summary

BjHAE (BJUB04G29220S) on Indian mustard chromosome B04 encodes a protein with multiple zinc-finger domains (NFX1, PHD, RING) and a PP2-like domain, annotated with diverse molecular functions including peptide hormone binding, transmembrane receptor protein tyrosine kinase activity, and chlorophyll binding. The gene is associated with numerous developmental and physiological processes, such as embryonic meristem development, radial axis specification, secondary thickening, lateral root branching, and photosynthesis. It has been linked to traits including floral organ size, anther morphology, plant male sterility, starch content, photosynthetic ability, and responses to auxin and brassinosteroids. Localization evidence connects the product to thylakoid membranes, plastid stroma, and pollen tubes. Studies of related genes in other species link the family to organ abscission, vascular development, meristem function, and stress responses.
