pOp6-driven reporter gene expression can be induced by DEX concentrations that do not inhibit plant growth. a-b) Wild-type (a) and pZmUbi:GUS (b) controls germinated and grown on ½ MS. c, d) T1 seedlings from inducible lines 17613.11 (c) and 17203.6 (d) germinated on ½ MS for 3 days before transferring to plates with 0, 0.01, 0.1, 1, 5, 10 and 30 μM DEX for 5 days before staining for GUS activity. Some lines segregated non-transgenic siblings which were not affected by DEX-mediated LhGR activation (marked by red arrows). Scale bar = 1 cm
