Hairy root induction and RUBY gene expression in soybean using the hypocotyl stabbing technique. (A) Emergence of the first hairy roots at the wounding/infection sites of hypocotyls (red arrow) (bar= 1 cm). (B) Emergence of red hairy roots, RUBY expression at the infection sites of hypocotyls (red arrow) (bar= 1 cm). (C) Composite soybean plants with fully red hairy roots (bar= 3 cm).
