Histochemical staining of root tips and emerging lateral roots in transgenic promoter reporter lines. Depicted are GUS-stained primary root tips of pYUC8::GUS (a) and pYUC9::GUS (c) at 1, 2, 4, 7, 10, and 14 days after germination. YUC8 (b) and YUC9 (d) promoter activity in the tips of lateral roots at 8, 12, and 14 days after emergence from the epidermis. [Scale bars, 50 μm (a–d)]. β-glucuronidase activity in pYUC8::GUS (e) and pYUC9::GUS (f) reporter lines during lateral root formation. Plants were grown sterilely on plates and then stained for reporter activity. [Scale bars: 100 μm (e–f)].
