Original Source: A new strategy for generating geminivirus resistant plants using a DNA betasatellite/split barnase construct.
The betasatellite DNA associated with cotton leaf curl disease contains a single ORF, betaC1, which is a pathogenicity determinant. Deletion of the betaC1 ORF showed that it was not required for betasatellite replication in the presence of Tomato leaf curl virus-Australia (TLCV-Au). A series of betasatellite/split mutant barnase gene constructs, in which a direct repeat of the Bacillus amyloliquefaciens barnase gene flanked the betasatellite, were shown to replicate in tobacco in the presence of TLCV-Au. A...

Antimicrobial resistance (AMR) is resistance of a microorganism to an antimicrobial medicine to which it was previously sensitive. Resistant organisms (they include bacteria, viruses and some parasi...

Reclaimed water as a reservoir of antibiotic resistance genes
Bacteria evolve faster than other organisms, partly because bacterial populations grow fast and hold enormous genetic diversity, and partly because many bacteria are capable of sharing their genes wit...
Honeybees harbor antibiotic-resistance genes
(American Society for Microbiology) Bacteria in the guts of honeybees are highly resistant to the antibiotic tetracycline, probably as a result of decades of preventive antibiotic use in domesticated...

Selection and spreading of antibiotic resistance in bacteria.
Use of an antibiotic may not only select for resistance against the agent itself, but may at the same time co-select for resistance against other antibiotics if resistance genes are linked on e.g. a p...
Identification of genes contributing to quantitative disease resistance in rice.
Despite the importance of quantitative disease resistance during a plant's life, little is known about the molecular basis of this type of host-pathogen interaction, because most of the genes underlyi...
