The importance of noncoding genome has become more evident in recent years. Before genome sequencing, the most well studied portion of our genome was protein coding genes. Interestingly, this coding portion accounted only for 1.5% of the genome, the rest being the noncoding sequences. Noncoding RNAs (ncRNAs) are involved in normal cell physiology, stress, and disease states. A class of small ncRNAs and miRNAs has gained much importance because of its involvement in human diseases such as cancer. Involvement of long ncRNAs have also been acknowledged in other human diseases, especially in neurodegenerative diseases...

In the present scenario of increased accumulation of pesticides in the environment, it is important to understand its impact on human health. The focus is on gene-environment interaction, highlighting the consequences and factors that may halt the biotransformation of some pesticides and change their actual dose response curve due to mixed exposure to pesticides. The paraoxonase and cytochrome P450 gene families are involved in the metabolism of oxon derivate (toxic than its parent compound) of organophosphate pesticides, thus, mutations in these genes may impact the metabolic outcome of pesticides and subsequent health hazards...

Seeding emergence and tiller number are the most important traits for wheat (Triticum aestivum L.) yield, but the inheritance of seeding emergence and tillering is poorly understood. We conducted a genomewide association study focussing on seeding emergence and tiller number at different growth stages with a panel of 205 elite winter wheat accessions. The population was genotyped with a high-density Illumina iSelect 90K SNPs assay. A total of 31 loci were found to be associated with seeding emergence rate (SER) and tiller number in different growth stages...

There is no 'one' procedure for extracting DNA from the whole blood of both mammals and birds, since each species has a unique property that require different methods to release its own DNA. Therefore, to obtain genomic DNA, a universal, rapid, and noncostly method was developed. A very simple biological basis is followed in this procedure, in which, when the blood is placed in water, it rapidly enters the RBCs by osmosis and causes cells to burst by hemolysis. The validity of extracting genomic DNA was confirmed by several molecular biological experiments...

Thinopyrum ponticum (2n = 70) serves as a valuable gene pool for wheat improvement. Line SN0224, derived from crosses between Th. ponticum and the common wheat cultivar Yannong15, was identified in the present study. Cytogenetic observations showed that SN0224 contains 42 chromosomes in the root-tip cells and 21 bivalents in the pollen mother cells, thereby demonstrating its cytogenetic stability. Genomic in situ hybridization, probed with the total genomic DNA of Th. ponticum, produced hybridization signals in the distal region of two wheat chromosome arms...

Fabry disease (FD) is a lysosomal storage disorder, which develops due to a deficiency in the hydrolytic enzyme, α-galactosidase A (α-Gal A). Alpha-Gal A hydrolyzes glycosphingolipid globotriaosylceramide (Gb3), and an α-Gal A deficiency leads to Gb3 accumulation in tissues and cells in the body. This pathology is likely to involve multiple systems, but it is generally considered to affect primarily vascular endothelium. In this study, we investigated mutations in the GLA gene, which encodes α-Gal A, in Mexican families with FD...

Allelic combinations of major photoperiodic (E1, E3, E4) and maturity (E2) genes have extended the adaptation of quantitative photoperiod sensitive soybean crop from its origin (China ∼35◦N latitude) to both north (up to ∼50◦N) and south (up to 40◦S) latitudes, but their allelic status and role in India (6-35◦N) are unknown. Loss of function and hypoactive alleles of these genes are known to confer photoinsensitivity to long days and early maturity. Early maturity has helped to adapt soybean to short growing season of India...

The plastid genome regions of two intergenic spacers, psbA-trnH and trnL-trnF, were sequenced to study the nucleotide diversity and phylogenetic relationships among Gladiolus cultivars. Nucleotide diversity of psbA-trnH region was higher than trnL-trnF region of chloroplast. We employed Bayesian, maximum parsimony (MP) and neighbour-joining (NJ) approaches for phylogenetic analysis of Gladiolus and related taxa using combined datasets from chloroplast genome. The psbA-trnH and trnL-trnF intergenic spacers of Gladiolus and related taxa-like Babiana, Chasmanthe, Crocus, Iris, Moraea, Sisyrinchium, Sparaxis and two out group species (Hymenocallis littoralis and Asphodeline lutea) were used in the present investigation...

The overexpression of epithelial cell adhesion molecule (EpCAM), a proto-oncogene, affects progression, treatment, and diagnosis of many adenocarcinomas. C-myc has been shown to be a downstream target of EpCAM and is also one of the most important proto-oncogenes routinely overexpressed in breast cancer. However, cooverexpression of EpCAM and c-myc genes has not been investigated in breast cancer tissues, particularly in Iranian population. The aim of this study was to assess the expression of EpCAM and c-myc genes in malignant breast cancer tissues using reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR) followed by analyses of the association between the outcomes...

Making interspecific hybridizations, where possible remains an unparalleled option for studying the intricacies of speciation. In the Drosophila bipectinata species complex comprising of four species, namely D. bipectinata, D. parabipectinata, D. malerkotliana and D. pseudoananassae, interspecific hybrids can be obtained in the laboratory, thus bequeathing an ideal opportunity for studying speciation and phylogeny. With the view of investigating the degree of divergence between each species pair, we planned to study the polytene chromosomes of the F1 hybrids, as it would mirror the level of compatibility between the genomes of the parental species...

Aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor best known for mediating xenobiotic-induced toxicity. AhR requires aryl hydrocarbon receptor nuclear translocator (ARNT) to form an active transcription complex and promote the activation of genes which have dioxin responsive element in their regulatory regions. The present study was performed to determine the complete cDNA sequences of porcine AhR and ARNT genes and their chromosomal localization. Total RNA from porcine livers were used to obtain the sequence of the entire porcine transcriptome by next-generation sequencing (NGS; lllumina HiSeq2500)...

Feral cattle residing in Chirikof Island, Alaska, are relatively distinct from breeds used in commercial production in North America. However, preliminary evidence suggested that they exhibit substantial genetic relationship with cattle from Yakutian region of Siberia. Thus, our objective was to further elucidate quantify the origins, admixture and divergence of the Chirikof Island cattle relative to cattle from Siberia and USA. Subject animals were genotyped at 15 microsatellite loci. Compared with Turano-Mongolian and North American cattle, Chirikof Island cattle had similar variation, with slightly less observed heterozygosity, fewer alleles per locus and a positive fixation index...

Transmembrane protein 8C (Tmem8C) is a muscle-specific membrane protein that controls myoblast fusion, which is essential for the formation of multinucleated muscle fibres. As most of the birds can fly, they have enormous requirement for the muscle, but there are only a few studies of Tmem8C in birds. In this study, we obtained the coding sequence (CDS) of Tmem8C in goose, predicted miRNAs that can act on the 3'UTR, analysed expression profiles of this gene in breast and leg muscles (BM and LM) during the embryonic period and neonatal stages, and identified miRNAs that might affect the targeted gene...
