<p>(A) Seven-day-old rice seedlings of wild-type and <i>35S::OsEXPA8</i> transgenic line1 plants. (B, C) Stereoscope images of the primary root of wild-type (B) and <i>35S::OsEXPA8</i> line1 (C) seedlings. Scale bars = 40 µm. (D, E) Epidermal morphology of the root hair growth zones of seminal roots of wild-type (D) and <i>35S::OsEXPA8</i> line1 (E) seedlings. Scale bars = 10 µm. Seedlings were grown for 7 days on half-strength solid MS medium vertically, and the root apex of was observed by stereoscope microscopes and cryo-scanning electron microscope (Cryo-SEM), respectively. (F) Root system architecture of two-month-old wild-type and <i>35S::OsEXPA8</i> line1 plants. (G) The plant morphology of two-month-old wild-type and <i>35S::OsEXPA8</i> line1 plants. (H) Flag leaf phenotype of two-month-old wild-type and <i>35S::OsEXPA8</i> line1 plants.</p
