UniprotTISSUE SPECIFICITY: Expressed in hairless cell files of the hypocotyl epidermis. Expressed in shoot apical meristem (SAM) with higher levels in L1 cells and the epidermal layer of young leaves. Expressed in primary root tips, in the L1 of apical inflorescence meristems, early flower primordia, carpel epidermis, ovule primordia, nucellus, chalaze and seed coat. {ECO:0000269|PubMed:16778018}.

Source Description
TAIREncodes a homeobox-leucine zipper family protein belonging to the HD-ZIP IV family. Mutants have trichomes that appear glass-like under a dissecting microscope as compared to the wild-type trichomes. The mutations do not affect trichome growth or branch number.
