Pt PIN9 Expression and Functional Characterization.

(A) Pt PIN9 is predominantly expressed in roots.

(B) LR formation significantly increased in 35S:PtPIN9 transgenics but not in 35S:PtPIN9AS transgenics.

(C) LRP density significantly increased in 35S:PtPIN9 transgenics but not in 35S:PtPIN9AS transgenics.

(D) Photos show in vitro aerial (top panels) and root (bottom panels) phenotypes of representative 35S:PtPIN9 transgenics and wild-type control plants. Top and bottom panels show photos of the same plants (1 month old) taken from the side and bottom of the Magenta box, respectively.

(E) Pt PIN9 expression is repressed after GA treatment.

(F) LR formation is repressed in 35S:PtPIN9 transgenics by GA application but to much less extent. Black and gray bars in (E) and (F) correspond to GA-treated and untreated samples; ** indicates significance at P < 0.01 as determined by Student's t test.
