HAE — Brassica juncea

Summary

BjHAE (BJUA09G03980S) on chromosome A09 of Indian mustard encodes a protein belonging to the NFX1-type zinc finger and RRM_NFXL1 domain families, annotated with multiple molecular functions including peptide receptor activity, transmembrane receptor protein tyrosine kinase activity, and cycloeucalenol cycloisomerase activity. The gene is associated with diverse biological processes such as embryonic meristem development, radial axis specification, secondary thickening, lateral root branching, and photosynthesis in photosystem II. It has been linked to numerous traits including floral organ size, carpel and anther morphology, plant male sterility, starch content, photosynthetic ability, oleic acid content, nitrate uptake, and auxin and brassinosteroid sensitivity. Localisation evidence connects the product to thylakoid membranes, plastid stroma, endocytic vesicles, and the pollen tube. Studies of related genes in other species link the family to vascular development, organ abscission, meristem function, and stress responses.
