Abstract: The present invention provides a chimeric recombinant DNA molecule comprising: a plurality of DNA sequences, each of which comprises a plant-functional promoter linked to a coding region, which encodes a virus-associated coat protein, wherein said DNA sequences are preferably linked in tandem so that they are expressed in virus-susceptible plant cells transformed with said recombinant DNA molecule to impart resistance to said viruses; as well as methods for transforming plants with the chimeric recombinant DNA molecule and for selecting plants which express at least one of said DNA sequences imparting viral resistance.

Abstract: In an assay for determination of beta-lactam antibiotic resistance in a target bacterial strain, the strain is grown in the presence of both a beta-lactamese inducing antibiotic and a beta-lactam indicator antibiotic [which kills or inhibits the growth of bacteria] unable to hydrolyze beta-lactam antibiotics. Growth, indicative of drug resistance in the target strain, is monitored by detecting a fluorophor released by the enzymatic cleavage of a metabolizable fluorogenic compound.
