Expression pattern analysis of PRX102. Shown are: A, RT-qPCR analysis of PRX102 in various tissues of rice plants. B, Longitudinal view of rice roots. Four distinct regions with different growth activities are represented as meristematic zone, transition zone, elongation zone, and maturation zone. Red boxes indicate the position of root shown in C–H. C–H, Fluorescent images from transgenic plants carrying the pPRX102::PRX102–GFP cassette. Photos were taken of the maturation zone (C and D), the elongation zone (E and F), and the transition zone of roots (G and H). GFP signals were detected in root hairs (white arrow heads, C and D) and trichoblasts (red arrow heads, E–H). PRX102–GFP accumulated at tips of growing root hairs (C and D) and bulge of trichoblasts (E and F) (white arrows). Fluorescent images (C, E, and G) and blight-field merged images (D, F, and H). Scale bars in C and D = 100 µm; scale bars in E–H = 20 µm
