COVID-19 is a novel coronavirus with an outbreak of unusual viral pneumonia in Wuhan, China, and then pandemic. Based on its phylogenetic relationships and genomic structures the COVID-19 belongs to genera Betacoronavirus. Human Betacoronaviruses (SARS-CoV-2, SARS-CoV, and MERS-CoV) have many similarities, but also have differences in their genomic and phenotypic structure that can influence th...

The chloroplastic DNA of 64 accessions of apple (Malus spp.) (54 Iranian genotypes, five commercial cultivars and five rootstocks) were analyzed to reveal their haplotypes by using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method. Approximately 4320 bp of the chloroplast genome was analyzed, by using two chloroplast universal primer pairs and two restriction ...

Plants produce two phosphorylated enzymes: pyrophosphate-dependent fructose-6-phosphate phosphotransferase (PFP) and ATP-dependent phosphofructokinase (PFK). However, the characterization of (PFK) family members their functions remains unexplored in Eastern Cottonwood (Populus deltoides). This study comprehensively analyzed 17 genes P. deltoides genome, including gene structure, conserved domai...

Marek’s disease (MD) is a lymphoproliferative disease of chickens characterized by lymphocyticinfiltration of various organs. The present study was an attempt to use polymerase chain reaction (PCR) tooptimize a rapid and reliable assay for detection of MDV genome. Detection of serotype 1 of MDV (MDV-1)was confirmed by presence of a 200 bp DNA fragment as a PCR product. Differentiation of MDV-1 ...

Background and Aims: Crimean-Congo hemorrhagic fever (CCHF) is a zoonosis caused by a Nairovirus of the family Bunyaviridae. Infection is transmitted to humans mostly by Hyalomma ticks. This study was conducted to determine the rate of CCHFV infection in ticks in Qom province of Iran. Materials and Methods: In this study, Reverse transcription – polymerase chain reaction (RT-PCR) was used...

Avian pneumovirus (APV) causes turkey rhinotracheitis (TRT) and swollen head syndrome (SHS) of chickens, which is usually accompanied by secondary bacterial infections that increase mortality. In Iran, some serological studies indicated that APV infection is endemic in commercial poultry industry. In this study we diagnosed APV genome molecularly in suspected broiler flock (4 weeks) in Iran and...

Genome resources have become crucial to assess genome-wide level of variation as well detect adaptive variation. This is particularly important for studying diversity in marine species inhabiting regions highly affected by accelerated climate warming and pollution, also known global change. A greater awareness the impacts change urgently needed ensure sustainable fisheries. Despite recent effor...

This study emphasizes the importance of aligning short reads in analysis human whole-genome sequencing data. The alignment process involves determining positions genetic sequences relative to a known reference genome sequence genome. Traditional methods use linear sequence, but this can lead incorrect alignment, especially when contain variations. In work, index file was modified using minimap2...
