the identification of molecular markers linked to leaf curl virus (clcuv) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. genetic analysis suggested that clcuv resistance is controlled by a single dominant gene. in this study, an interspecific f2 population derived from a cross of gossypium barbadense and g...

Purpose: Tumor-specific DNA has recently been detected in the plasma of lung, head and neck, breast, and colon cancer patients. Detection of tumor-specific genetic materials in cancer patients at sites distant from the tumor, such as in the blood, may provide a unique and valuable tumor marker for diagnosis and prognosis. Experimental Design: The present investigation was aimed at determining t...

Burkholderia cepacia is a problematic pathogen that may spread among patients with cystic fibrosis (CF). One highly infectious CF strain that causes epidemics in both the United Kingdom and eastern Canada has been shown to possess both the cable pilin subunit gene (cblA) and a unique combination of insertion sequences. However, no genetic markers linking this strain type with other types epidem...

malaria is currently one of the most important causes of mortality in developing countries. high resistance to available antimalarial drugs has been reported frequently, thus it is crucial to focus on the discovery of new antimalarial drugs. artemisinin, an effective antimalarial medication, is isolated from various artemisia species. to identify the artemisia species producing high quantity of...

ABSTRACT A three-generation American chestnut x Chinese chestnut pedigree was used to construct a genetic linkage map for chestnut and to investigate the control of resistance to Endothia parasitica (chestnut blight fungus). DNA genotypes for 241 polymorphic markers (eight isozymes, 17 restriction fragment length polymorphisms [RFLPs], and 216 random amplified polymorphic DNAs [RAPDs]) were ass...

DNA markers application in marker-assisted breeding of cotton is handicapped due to low genetic diversity germplasm. The present study was designed identify markers, predominately simple sequence repeats (SSRs), associated with tolerance/resistance heat stress as a consequence boll shedding. To find out the total 24 genotypes and 50 SSR primers were used. Total 288 alleles produced an average 5...

Channel-based models of human spatial vision require that the output of spatial filters be pooled across space. This pooling yields global estimates of local feature attributes such as orientation that are useful in situations in which that attribute may be locally variable, as is the case for visual texture. The spatial characteristics of orientation summation are considered in the study. By a...

This study investigated the association between both polymorphisms and metabolic marker changes of leptin gene, body weight, weight gain, carcass traits, feed intake, conversion ratio. Blood samples were collected from 60 V-line Baladi Black rabbits for DNA extraction biochemical analysis. sequencing (202-bp) revealed four non-synonymous single nucleotide polymorphism (SNPs) that characterized ...

Several recent studies of genome evolution indicate that the rate of DNA loss exceeds that of DNA gain, leading to an underlying mutational pressure towards collapsing the length of noncoding DNA. That such a collapse is not observed suggests opposing mechanisms favoring longer noncoding regions. The presence of transposable elements alone also does not explain observed features of noncoding DN...
