Hygromycin B is an

protein synthesis.[1]

History

Hygromycin B was originally developed in the 1950s for use with animals and is still added into swine and chicken feed as an anthelmintic or anti-worming agent (product name: Hygromix). Hygromycin B is produced by Streptomyces hygroscopicus, a bacterium isolated in 1953 from a soil sample. Resistance genes were discovered in the early 1980s.[2][3]

Mechanism of action

Hygromycin is active against both

polypeptide synthesis. It stabilizes the tRNA-ribosomal acceptor site, thereby inhibiting translation.[citation needed

Use in research

In the laboratory it is used for the selection and maintenance of prokaryotic and eukaryotic cells that contain the hygromycin

resistance gene. The resistance gene is a kinase that inactivates hygromycin B through phosphorylation.[4] Since the discovery of hygromycin-resistance genes, hygromycin B has become a standard selection antibiotic in gene transfer experiments in many prokaryotic and eukaryotic cells. Based on impurity monitor method,[5] four different kinds of impurities are discovered in commercial hygromycin B from different suppliers and toxicities of different impurities to the cell lines are described in the following external links.[citation needed

Use in plant research

Hygromycin

transformants.[6]

Fungus Coniothyrium minitans was transformed with the hygromycin B resistance gene to improve the infection rates of Sclerotinia sclerotiorum, a fungal parasite of many crops.[7]
