Evolving disease resistance genes
Current Opinion in Plant Biology, 2005Defenses against most specialized plant pathogens are often initiated by a plant disease resistance gene. Plant genomes encode several classes of genes that can function as resistance genes. Many of the mechanisms that drive the molecular evolution of these genes are now becoming clear.

PLANT DISEASE RESISTANCE GENES
Annual Review of Plant Physiology and Plant Molecular Biology, 1997▪ Abstract In “gene-for-gene” interactions between plants and their pathogens, incompatibility (no disease) requires a dominant or semidominant resistance (R) gene in the plant, and a corresponding avirulence (Avr) gene in the pathogen. Many plant/pathogen interactions are of this type.

Nonhost resistance genes and race-specific resistance
Trends in Microbiology, 1993Apart from physical barriers, plants have two major types of defense against potential pathogens. In 'race-specific' resistance, plants match single mendelian resistance genes with the 'avirulence' genes possessed by races of a pathogen. Plants also employ the more complex and evolutionarily more robust system of 'nonhost resistance' against a broad ...

Current Opinion in Plant Biology, 1998
Plant resistance genes are highly polymorphic and have diverse recognition specificities. These genes often occur as members of clustered gene families that have evolved through duplication and diversification. Regions of nucleotides conserved between family members and flanking sequences facilitate equal or unequal recombination events.

Plant nematode resistance genes
Current Opinion in Plant Biology, 1999Root-knot and cyst nematodes cause severe damage to crops throughout the world. Genes conferring resistance against nematodes have been identified in many plant species and several of these have been, or soon will be, cloned. Nematode biotypes that can infect resistant plants have been identified.

Determining Hosts of Antibiotic Resistance Genes: A Review of Methodological Advances
, 2020Advancing environmental research on antibiotic resistance will require developing better databases of not only the occurrences of antibiotic resistance genes (ARGs) in the environment but also whic...

Currently, the use of life-saving antibiotics is growing up rapidly due to its multi-effectiveness for curing bacterial infected diseases. If same antibiotics are frequently consumed, then it kills susceptible bacteria but leaves resistance gene. Thus, some bacteria obtain resistance capacity against some antibiotics called antibiotic resistance ...

Myeloprotection with drug-resistance genes
The Lancet Oncology, 2002One of the many applications of gene transfer for cancer gene therapy is the transfer of drug-resistance genes into bone-marrow stem cells for myeloprotection. Protection of the hosts' bone marrow should allow for dose escalation that may be useful for eradicating minimal residual disease in a post-transplant situation.

Resistance and the jumping gene
BioEssays, 2005AbstractTransposons are well‐known architects of genetic change but their role in insecticide resistance has, until recently, only been speculated upon.1 Transposon insertion, or transposon‐mediated transposition, could alter either metabolic enzymes capable of degrading pesticides or could change the functionality of insecticide targets.
