2-BP impaired root hair growth. A. Primary roots from 4 DAG seedlings of wild type treated with either DMSO or 2-BP. B. Primary roots from 4 DAG seedlings of pat10-2 treated with either DMSO or 2-BP. C. Primary roots from 4 DAG seedlings of tip1-4 treated with either DMSO or 2-BP. D-E. Representative root hairs at the hair elongation zone of 4 DAG seedlings treated with either DMSO (D) or with 2-BP (E). F-G. Root hair length (F) and width (G). Results are means ± standard errors (SE), N = 4. Length or width of mature wild-type root hairs treated with DMSO was set as 1. Empty bars represent DMSO treatment while filled bars represent 2-BP treatment. Asterisks indicate significant difference (Student’s t-test, P < 0.05). Bars = 500 μm for (A-C); 20 μm for (D-E).
