Try the Gritz and Davies paper, 'Plasmid-encoded hygromycin B resistance:
the sequence of hygromycin B phosphotransferase gene and its expression in
E. coli and S. cerevisiae', Gene 25 (1983), 179-188. This descibes the
isolation and sequencing of the hygR gene, along with info about
hygromycin and how the resistance gene works. I'm not convinced by the
sensitivity threshold of yeast though - my strain will grow at up to about
400ug/ml hyg without the resistance gene in it (up to 2mg/ml with).
