Scanning electron micrograph of floral organs and expression levels of genes related to floral organ development and seed formation between TeAG1 transgenic Arabidopsis and wild-type lines. (a-u) Scanning electron micrograph of floral organs between Sl-TeAG1 transgenic Arabidopsis and wild-type lines; (a, b) Adaxial (a) and abaxial (b) epidermis cells of sepals of wild-type; (c) The papilla-like cells at the top of the carpelloid sepals of transgenic plant; (d, e) Adaxial (d) and abaxial (e) epidermis cells of carpelloid sepals of transgenic plant; (f, g) The epidermal cells at the upper (f) and bottom portion (g) of the petals of wild-type; (h) The petals transformed into anther-like structure in transgenic lines; (i, k) The epidermal cells at the top (i) and bottom (k) part of anther-like structure; (l) The anther structure of wild-type lines; (m, n) The epidermal cells of anther (m) and filament (n) in wild-type lines; (o) The papilla cells of stigma in wild-type lines; (p) the epidermal cells of style in wild-type lines; (q) The anther structure of transgenic plant; (r, s) The epidermal cells of anther (r) and filament (s) in transgenic plant; (t) The papilla cells of stigma in transgenic plant; (u) The epidermal cells of style in transgenic plant. (v) Expression levels of genes related to floral organ development and seed formation in control and transgenic Arabidopsis flowers by qRT- PCR analysis. WT1: wild-type line 1; WT2: wild-type line 2; WL1: Wl-TeAG1 line 1; WL2: Wl-TeAG1 line 2; SL1: Sl-TeAG1 line 1; SL2: Sl-TeAGL1 line 2. * expression level of endogenous genes in transgenic plants was 2 times higher or 1/2 lower than that in wild-type plants
