Background & objective: Microarray and next generation sequencing (NGS) data are the important sources to find helpful molecular patterns. Also, the great number of gene expression data increases the challenge of how to identify the biomarkers associated with cancer. The random forest (RF) is used to effectively analyze the problems of large-p and smal...

The combination of cytoplasmic male sterility (CMS) in one parent and a restorer gene (Rf) to restore fertility in another are indispensable for the development of hybrid varieties. To genotype rice lines at the restoring fertility (Rf) loci, 38 lines were crossed with a sterile tester (rfrf) line. Pollen fertility test was performed to identify sterile and fertile F1 hybrids. Seven lines were ...

the present study was carried out with the objective of validating linked ssr markers to rf genes and adopting marker assisted selection (mas) for restorer/non-restorer line detection in wild abortive (wa) type of cytoplasmic male sterility (cms). twelve ssr markers reported to be linked to rf genes were analyzed in the mapping population of nedaa/pajouhesh. among these, three markers, namely, ...

Background: DNA microarray is a useful technology that simultaneously assesses the expression of thousands of genes. It can be utilized for the detection of cancer types and cancer biomarkers. This study aimed to predict blood cancer using leukemia gene expression data and a robust ℓ2,p-norm sparsity-based gene selection method. Materials and Methods: In this descriptive study, the microarray ...

tagging of restorer genes for wild abortive (wa) of cytoplasmic male sterility was carried out by studying 10000 individuals from an f2 population of a cross between ir58025a × ir42686r. this study was primarily carried out to reduce the distance of the already known markers for rf gene. this f2 population was identified to be unique as four rf genes could be tagged to ssr markers on chromosome...

Perennial ryegrass (Lolium perenne L.) is widely used for forage production in both permanent and temporary grassland systems. To increase yields in perennial ryegrass, recent breeding efforts have been focused on strategies to more efficiently exploit heterosis by hybrid breeding. Cytoplasmic male sterility (CMS) is a widely applied mechanism to control pollination for commercial hybrid seed p...

PURPOSE The biological effects of exposure to mobile phone emitted radiofrequency (RF) radiation are the subject of intense study, yet the hypothesis that RF exposure is a potential health hazard remains controversial. In this paper, we monitored cellular and molecular changes in Jurkat human T lymphoma cells after irradiating with 1763 MHz RF radiation to understand the effect on RF radiation ...

OBJECTIVE The main genetic risk factor for rheumatoid arthritis (RA) is the shared epitope (SE) of HLA-DR, while smoking is an important environmental risk factor. We studied a potential gene-environment interaction between SE genes and smoking in the etiology of the 2 major subgroups of RA: rheumatoid factor (RF)-seropositive and RF-seronegative disease. METHODS A population-based case-contr...

The class II genes of the major histocompatibility complex (MHC) encode a family of cell surface glycoproteins that present processed antigen to the T cell receptor. Class II genes are regulated coordinately, responding to both immunologic and developmental signals. Conserved sequence elements 5' to class II genes have been shown to be important in transcriptional control. One of these sequence...
