Genotype; RAPD; Resistance; Varroa destructor

The mite Varroa destructor is the main pest causing damage to apiculture worldwide. In Brazil and other parts of the world, where bees of African origin and their hybrids predominate, the bees can survive these mites without treatment. Studies have shown a correlation between the various genotypes of the mite and its fertility in different geographical regions. Information about ... more

Line-by-isolate interaction; Phaseolus vulgaris; Resistance; Straw test

The aims of this study were to evaluate the reaction of common bean lines to white mold, the aggressiveness of different Sclerotinia sclerotiorum isolates from various common bean production areas in Brazil, and comparison of the diallel and GGE (genotype main effect plus genotype-by-environment interaction) biplot analysis procedures via study of the line-by-isolate interaction ... more

DLY; Jiangquhai porcine lean strain; Mucosal immunity; Mycoplasma hyopneumoniae; Resistance

The Jiangquhai porcine lean strain (JQHPL) is a new pork meat-type strain that has been developed in recent years from the parent lines Duroc, Fengjing, and Jiangquhai pigs (DurocxFengjing pigxJiangquhai pig). Enzootic pneumonia (EP) in pigs induced by Mycoplasma hyopneumoniae (M. hyopneumoniae) is a chronic respiratory disease of pigs, generating high economic ... more

Carbapenem; Carbapenemase; Efflux pumps; Porin; Pseudomonas aeruginosa; Resistance

We explored the mechanism of the development from sensitivity to resistance to carbapenem in Pseudomonas aeruginosa. Two P. aeruginosa strains were collected during treatment with carbapenem. Strain homology was investigated using pulsed-field gel electrophoresis. Porin oprD2 expression was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE ... more

Clinical significance; E-cadherin; Epidermal growth factor receptor-tyrosine kinase inhibitor; Molecular treatment; Resistance

We examined the effect of E-cadherin expression on epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) molecular targeted therapy sensitivity/resistance. We treated MCF-7, MDA-MB-231, T24, SiHa, H460, SK-HEP-1, MHCC97-H, and THP-1 cells with the EGFR-TKIs PD153035 and gefitinib, and then tested the drug-resistance and sensitivity using the MTT method, calculated IC ... more

16S rRNA methylase gene; Acinetobacter baumannii; Aminoglycoside-modifying enzyme gene; Aminoglycosides; Molecular identification; Resistance

The aim of this study was to investigate the mechanism underlying the drug resistance of Acinetobacter baumannii toward aminoglycosides. A total of 32 A. baumannii strains were identified by molecular identification and subsequently isolated. The isolates were then amplified by polymerase chain reaction to analyze the 9 aminoglycoside-modifying enzyme genes and 7 16S ... more

AFLP; Biofuel; Germplasm; Panicum; Switchgrass; trnL (UAA)

Switchgrass (Panicum virgatum) is a perennial warm-season grass native to North America that has been identified as a dedicated cellulosic biofuel crop. We quantified genetic diversity in tetraploid switchgrass germplasm collected at Oklahoma State University and characterized genetic relatedness among the collections from distinct regions. Fifty-six tetraploid accessions, ... more

AFLP; Argopecten; Heterosis; Hybrid; SSR

Argopecten purpuratus and Argopecten irradians irradi­ans hybridization was successfully performed and the hybrid offspring displayed apparent heterosis in growth traits. To better understand the genetic basis of heterosis, the genomic composition and genetic varia­tion of the hybrids were analyzed with amplified fragment length poly­morphism (AFLP) and simple sequence repeat (SSR) ... more

AFLP; Amorphophallus konjac; Central China; Crop; Genetic diversity

Amorphophallus konjac is an economically important crop. In order to provide baseline information for sustainable development and conservation of the wild plant resources of A. konjac, we studied the genetic diversity and population structure of this species using amplified fragment length polymorphism (AFLP) molecular markers. We sampled 139 individuals from ... more

Canopy form; Cypress; Fastigate; Pseudo-test cross; RAPD; SCAR

Gene mapping for a Cupressus species is presented for the first time. Two linkage maps for the Mediterranean cypress (Cupressus sempervirens) varieties, C. sempervirens var. horizontalis and C. sempervirens var. pyramidalis, were constructed following the pseudo-testcross mapping strategy and employing RAPD, SCAR and morphological ... more
