Beta-glucuronidase (GUS) expression analysis in the BA-GUS transgenic line, consisting of auxin-responsive domains of PS-IAA4/5 promoter and GUS reporter, revealed that 1-NOA and CSI act as auxin uptake inhibitors in Arabidopsis roots.

Tumors were induced in transformants of Trifolium repens (L.), containing the beta-glucuronidase ( GUS)-fused auxin-responsive promoter ( GH3) or chalcone synthase ( CHS2) genes, and in transformants of Arabidopsis thaliana (L.) Heynh., containing the GUS-fused synthetic auxin response element DR5.

AtPRP3/beta-glucuronidase (GUS) expression increased in roots of transgenic seedlings treated with either 1-aminocyclopropane-1-carboxylic acid (ACC) or alpha-naphthaleneacetic acid (alpha-NAA), compounds known to promote root hair formation.

Three kb of the peroxidase promoter was joined to the coding region of the Escherichia coli beta-glucuronidase gene (GUS), and transiently expressed in tobacco mesophyll protoplasts in the presence or absence of plant growth regulators.

Hypocotyls and cotyledons obtained from 7-day-old seedlings were co-cultivated with Agrobacterium tumefaciens strain EHA101/pIG121Hm that harbored genes for beta-glucuronidase (GUS), kanamycin, and hygromycin resistance.

These plasmids contain the beta-glucuronidase gene ( gusA) as a reporter gene and the hygromycin phosphotransferase and neomycin phosphotransferase II ( nptII) genes as selective markers.

However, their expression levels and patterns differ: ARGAH1 encoded the minor activity, and ARGAH1-driven beta-glucuronidase (GUS) was expressed throughout the seedling; the ARGAH2::GUS expression pattern was more localized.
