General description

4-Methylumbelliferyl β-D-galactopyranoside (MUG) is a UV-absorbing dye that serves as a fluorescent substrate for β-galactosidase in a planar yeast estrogen screen (pYES) for the detection of estrogen active compounds.

Application

4-Methylumbelliferyl β-D-galactopyranoside has been used as a substrate in β-galactosidase activity assay.

The phytohormone 7-iso-(+)-jasmonoyl-L-isoleucine (JA-Ile) mediates plant defense responses against herbivore and pathogen attack, and thus increases plant resistance against foreign invaders. However, JA-Ile also causes growth inhibition; and therefore JA-Ile is not a practical chemical regulator of plant defense responses.

The ability of Escherichia coli O157:H7 to induce cellular damage leading to disease in humans is related to numerous virulence factors, most notably the stx gene, encoding Shiga toxin (Stx) and carried by a bacteriophage. Loss of the Stx-encoding bacteriophage

Most land plants have evolved a mutualistic symbiosis with arbuscular mycorrhiza (AM) fungi that improve nutrient acquisition from the soil. In return, up to 20% of host plant photosynthate is transferred to the mycorrhizal fungus in the form of lipids

Inducible gene expression has emerged as a powerful tool for plant functional genomics. The estrogen receptor-based, chemical-inducible system XVE has been used in many plant species, but the limited systemic movement of inducer β-estradiol in transgenic rice plants has prohibited

For the planar yeast estrogen screen (pYES), 4-methylumbelliferyl-β-d-galactopyranoside was generally employed as substrate, delivering blue fluorescing 4-methylumbelliferone after enzymatic cleavage by the YES reporter β-d-galactosidase as the positive signal for the presence of estrogen active compounds (EAC).
