Expression of the blasticidin S deaminase gene (bsr) in tobacco: Fungicide tolerance and a new selective marker for transgenic plants

Abstract

Blasticidin S (BS), a fungicide of microbial origin, is used for the practical control of rice blast disease. It has broad antimicrobial activity but occasionally exhibits adverse phytotoxic effects on some dicot plants. An inactivating enzyme, BS deaminase, was discovered in the BS resistant strain, Bacillus cereus K55-S1, and the structural gene, bsr, for… (More)
