Additional file 4: of A detailed expression map of the PIN1 auxin transporter in Arabidopsis thaliana root

PIN1 expression in closer proximity to the developing lateral primordium. a-d. PIN1 signal (red arrows) was detected in the xylem elements. c. Magnification of the white box from figure b. e. PIN1 signal (red arrows) was detected in individual cells of the outer layers of the primary root. The white inset shows the same primordium, but with a different focal plane. Anti-PIN1 staining is in green, DAPI is in the white channel. Bars = 50 μm. (TIF 16686 kb
