Phenotype of <i>35S::GRP23</i> transgenic plants.

<p>(A) Hypocotyl phenotype of Col and <i>35S::GRP23</i> transgenic lines (OE1, OE2, and OE3) after germination for 8 days. Bars = 1 cm.(B) GRP23 expression in Col and <i>35S::GRP23</i> seedlings detected by qRT-PCR. Data are means ± SD (n = 3). (C) Hypocotyl length of Col and <i>35S::GRP23</i> seedlings after germination for 8 days. Data are means ± SD (<i>n</i> > 15). Different letters a and b represent significantly differences among the lines (*<i>P</i> < 0.05) by Student’s <i>t</i> test. (D) Cell cycle progression in hypocotyls of Col and <i>35S::GRP23</i> line 2 (OE2) analyzed by flow cytometry. (E) Mean mitotic index in hypocotyl of Col and <i>35S::GRP23</i> line 2. Student’s <i>t</i> test, **<i>P</i> < 0.01. (F) Expression levels of cell cycle-related genes in Col and <i>35S::GRP23</i> line 2. Data are means ± SD (n = 3).
