HDG1_ARATH | developmental stage | During embryogenesis, first observed at low levels in the embryo protoderm starting at the late globular stage (PubMed:25564655). In primary and lateral roots, observed in the epidermis, the outer layer of columella cells and lateral root cap (PubMed:25564655). Restricted to the epidermal cell layer during floral organ formation (PubMed:23590515). Also present in flower meristems, shoot apical mersitems (SAM) and leaf primordia (PubMed:25564655). |
HDG1_ARATH | function | Probable transcription factor (By similarity). Promotes cuticle development probably by modulating the expression of the downstream genes BDG and FDH, possibly repressed in a CFL1-dependent manner (PubMed:21954461). Involved, together with PDF2, in the regulation of flower organs development by promoting the expression of APETALA 3 (AP3) in the epidermis and internal cell layers of developing flowers (PubMed:23590515). In opposition to BBM, seems to promote cell differentiation and giant cell identity via transcriptional repression of meristem and cell proliferation genes (PubMed:25564655). |
HDG1_ARATH | similarity | Belongs to the HD-ZIP homeobox family. Class IV subfamily. |
HDG1_ARATH | tissue specificity | Expressed in trichomes forming at the base of young leaves, in endodermal cell lines around emergent lateral roots and in the epidermal layer of the stamen filament. |
