P-Glucuronidase Enzyme Histochemistry on Semithin Sections of Plastic-Embedded Arabidopsis Explants

transgenic research for promoter evaluation. The β-glucuromdase gene ( gusA or uidA ), isolated from Escherichia coli, has been exploited over many years to monitor plant promoter activity. In situ enzyme histochemical methods are used to localize the cells
