Effects of overexpressing GmEXPB2 on root architecture of soybean whole transgenic lines. A, Root hair growth of 2-d-old soybean seedlings. The red box represents the amplifying region of root hair zone for OX or wild-type (WT) soybean plants, respectively. B, Primary root length including root hair and nonroot hair zone of 2- and 3-d-old seedlings. C, Cross-sectional images of soybean root hairs. D, Root hair number per whole cross section. E, Percentage of root hairs to epidermal cells per section. OX refers to soybean whole transgenic lines overexpressing GmEXPB2. Each bar was the mean of 10 biological replicates with se. Asterisks represent significant differences between OX and wild-type plants for different parameters at the same growth period in Student’s t tests (*, 0.01 < P ≤ 0.05; **, 0.001 < P ≤ 0.01; and ***, P ≤ 0.001). Bars = 100 μm.
