HAE — Brassica juncea

Summary

BjHAE (BJUB03G55960S) on Indian mustard chromosome B03 encodes a protein with NFX1-family zinc-finger and RING-finger domains, annotated with peptide receptor activity, transmembrane receptor protein tyrosine kinase activity, and cycloeucalenol cycloisomerase activity. The gene is associated with embryonic meristem development, radial axis specification, secondary thickening, lateral root branching, and photosynthesis-related processes including photosystem II assembly and light harvesting. It is linked to numerous traits including floral organ size and development, carpel and gynoecium morphology, anther morphology, plant male sterility, starch content and grain synthesis, oleic acid content, cytokinin content, nitrate uptake, auxin and brassinosteroid sensitivity, and vegetative-to-reproductive phase transition. Localisation evidence connects the product to thylakoid membranes, plastid stroma, endocytic vesicles, and the photosystem II oxygen-evolving complex.
