HD-ZIP IV family of homeobox-leucine zipper protein with lipid-binding START domain-containing protein
Curated Summary
Glabra 2, a homeodomain protein affects epidermal cell identity including trichomes, root hairs, and seed coat. It also down-regulates seed oil content. Expressed in atrichoblasts and required to suppress root hair development. Also expressed abundantly during early seed development. Directly regulated by WER.
