HAE — Brassica juncea

Summary

BjHAE (BJUA06G35970S) on Indian mustard chromosome A06 encodes a protein with multiple zinc-finger domains (PHD, RING, NFX1-type), an RRM_NFXL1 motif, and a PP2-like domain, and is annotated with diverse molecular functions including peptide receptor activity, transmembrane receptor protein tyrosine kinase activity, chlorophyll binding, and cycloeucalenol cycloisomerase activity. The gene is associated with embryonic meristem development, radial axis specification, secondary thickening, lateral root branching, and negative regulation of hydrogen peroxide biosynthesis. 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, cytokinin and auxin sensitivity, nitrate uptake, and light intensity response. Localisation evidence connects the product to the thylakoid membrane, plastid stroma, pollen tube, and endocytic vesicles.
