Histochemical GUS Staining Patterns of DR5::uidA and CYCB1;1::uidA in Transfer Experiments from NPA to NAA, from NPA to MS Medium, and from MS Medium to NAA.
(A) DR5::uidA on NPA. The arrow indicates the root apical meristem.
(B) DR5::uidA after transfer from NPA to NAA for 1.5 h.
(C) DR5::uidA after transfer from NPA to NAA for 3 h.
(D) DR5::uidA after transfer from NPA to MS medium for 6 h.
(E) DR5::uidA after transfer from NPA to MS medium for 6 h (detailed image).
(F) CYCB1;1::uidA after transfer from NPA to MS medium for 6 h.
(G) CYCB1;1::uidA after transfer from NPA to MS medium for 10 h. The arrow indicates the first lateral root initiation site at the apical end of the root.
(H) CYCB1;1::uidA after transfer from MS medium to NAA for 4 h. Arrows indicate the first initiation sites in the basal half of the root.
(I) CYCB1;1::uidA after transfer from MS medium to NAA for 6 h. The lateral root initiation sites are along the entire length of the root. Arrows indicate developing lateral root primordia.
(J) CYCB1;1::uidA after transfer from MS medium to NAA for 8 h. The entire pericycle is activated.
Bars = 1 mm.
