Antimicrobial resistance gene monitoring in aquatic environments
… framework for monitoring antimicrobial resistance gene (ARG) dissemination in the aquatic environment. The work opens with a review of the relevant literature and outlines the importance of an environmental framework for monitoring ARG dissemination as part of antimicrobial resistance …

Functional Dissection of Arabidopsis Thaliana Resistance Gene RPS2
… RPS2 that modify expression and strength of the resistance response. Further characterization and cloning of the RPS2- and RPM1-interacting loci, conjoined with functional analysis of RPS2 protein domains such as the LRRs and the NBS, should provide valuable insights into the structure, molecular …

Towards Cloning the Leaf Rust Resistance Gene Rph5
… been reported in susceptible cultivars. The Rph5 gene confers resistance to the most prevalent races (8 and 30) of barley leaf rust in the United States. Therefore, the molecular mapping of Rph5 is of great interest. Genetic studies were performed by analysis of 93 and 91 F2 plants derived from …

Identification of the cir1 disease resistance gene in Arabidopsis thaliana
… The defence-related cir1 (constitutively induced resistance 1) mutant was first isolated in an effort to identify components of the Arabidopsis thaliana defence system essential for resistance against pathogens. The cir1 mutant has previously been described as having increased resistance to the …

Antibiotic resistance gene abundance in feces of calves fed pirlimycin-dosed whole milk
… the incidence and proliferation of antibiotic resistance genes (ARG) in the gut and fecal microbiome. Non-saleable, antibiotic-containing milk from cows treated with antibiotics (waste milk) is commonly fed to dairy calves but the effects of ingestion of antibiotics at an early age on the gut …

Characterization of a novel tetracycline resistance gene from the Bacteroides transposons Tn4351 and Tn4400
A tetracycline resistance ($\rm \sp{*}Tc\sp{r}$) gene that was originally found on two Bactetoides transposons, Tn4351 and Tn4400, confers resistance on Escherichia coli, but only when the cells are grown aerobically. I first showed that the product of the $\rm \sp{*}Tc\sp{r}$ gene is a 44 kDa …

The association of IS1133 with an aminoglycoside resistance gene, aacC2a, in Acinetobacter baumannii isolates
Includes bibliographical references (leaves 93-103).

Molecular Mapping of Disease-Related Expressed Sequence Tags and Resistance Gene Analogues in Soybean
… resulting in a need to improve its disease resistance. The objectives of this study were to 1) design primers and develop PCR-based markers from disease-related expressed sequence tags (ESTs) and resistance gene analogues (RGAs), 2) assess the utility of such markers by diversity analysis of …

Molecular Mapping Of A Soybean Mosaic Virus (SMV) Resistance Gene In Soybean (Glycine Max)
… and quality of soybean crop. Three independent genes Rsv1, Rsv3, and Rsv4, were found to provide host resistance in soybean. Rsv1 confers resistance to all but most virulant strains of SMV. Rsv1 has been mapped to soybean molecular linkage group (MLG) F by using molecular markers. The purpose of …

Using Synthetic Gene Clusters to Model Resistance Gene Evolution by Meiotic Recombination in Arabidopsis thaliana
… is based on dozens of constitutively expressed resistance (R) genes. R genes recognize pathogen gene products as signals of invasion. We are interested in how plants evolve R genes to keep pace with rapidly evolving pathogen populations. The mechanisms that drive the evolution of new R genes are …

Identification and mapping of a resistance gene to barley leaf rust(<I>Puccinia hordei</I> G. Otth)
… incorporation of new and effective sources of resistance are crucial to the success of barley breeding programs. Two types of resistance have been identified. They are race-specific resistance and partial resistance. A hypersensitive reaction by the host to infection of <I>P. hordei</I> …

Genetic mechanisms contributing to antimicrobial resistance: gene repression in Mycobacterium, gene transfer in Salmonella, and phage sensitivity in Escherichia
Bacteria develop resistance to antimicrobial agents through genetic mutation or horizontal acquisition of genetic material from resistant cells. Mycobacterium, Salmonella, and Escherichia are all capable of causing disease, and each demonstrates increasing resistance to conventional antibiotic …

Reproduction of a root-knot nematode population on flue-cured tobacco homozygous for Rk1 and/or Rk2 resistance genes and the effect of soil temperature on resistance gene efficacy
… L.). Most commercial cultivars possess the Rk1 gene, providing resistance to races 1 and 3 of Meloidogyne incognita and race 1 of M. arenaria. This initiated a shift in root-knot populations to other species and races, creating a need for resistance to those populations. Numerous cultivars …
