Article Synopsis
  • - The study analyzed 837 ewes from specific Iranian sheep breeds and one Greek breed to explore genetic factors related to prolificacy using OvineSNP50K arrays.
  • - Researchers applied statistical analyses to identify 19 genomic regions across various chromosomes that are under selection for prolificacy traits.
  • - Bioinformatic analysis indicated these regions contain candidate genes tied to prolificacy, milk yield, and body weight, suggesting opportunities for future research on genetic links to sheep prolificacy traits.

Mastitis is known as intramammary inflammation, which has a multifactorial complex phenotype. However, the underlying molecular pathogenesis of mastitis remains poorly understood. In this study, we utilized a combination of RNA-seq and miRNA-seq techniques, along with computational systems biology approaches, to gain a deeper understanding of the molecular interactome involved in mastitis.

Article Synopsis
  • In Iran, river buffalo are economically important due to their ability to thrive in harsh climates and produce valuable milk from low-quality feed, with recent studies focusing on their genetic variability using SNPs.
  • A study analyzed 361 buffalo from three breeds (Azeri, Khuzestani, and Mazandarani) using the Axiom® Buffalo Genotyping Array, resulting in the identification of 9,550 CNVs and 302 CNVRs that cover approximately 1.97% of the buffalo genome.
  • The findings contribute to understanding the genetic diversity and adaptations of buffalo, linking specific genes and traits associated with morphology, health, milk, and meat production to their evolutionary history and recent selective

Article Synopsis
  • The study focuses on runs of homozygosity (ROH) in river buffalo genomes to assess inbreeding and identify regions under selection pressure, using a dataset of 254 Azeri and 115 Khuzestani buffalo.
  • A total of 9,102 ROH were discovered, revealing average genome autozygosity of 4.35% in Azeri and 5.96% in Khuzestani buffalo, with higher inbreeding values in Azeri compared to Khuzestani breeds.
  • Eleven ROH islands were identified, with genes linked to traits like body size, immune response, milk production, pigmentation, reproductive traits, and bone development, highlighting the biological significance of these areas in

Article Synopsis
  • The study investigated linkage disequilibrium (LD), effective population size, and runs of homozygosity (ROHs) in the Zandi sheep breed using genetic data from 96 samples.
  • It was found that LD for SNP pairs diminishes quickly as the distance between them increases, with Zandi sheep having a historical effective population size of 6475 and a recent size of 122.
  • The research also identified 558 ROH regions, with the finding that Zandi sheep showed a faster rate of LD reduction compared to other species, suggesting the need for a denser SNP panel for future genetic studies.

Accuracy of genome-wide association studies, and the successful implementation of genomic selection depends on the level of linkage disequilibrium (LD) across the genome and also the persistence of LD phase between populations. In the present study LD between adjacent SNPs and LD decay between SNPs was calculated in three Iranian water buffalo populations. Persistence of LD phase was evaluated across these populations and effective population size (Ne) was estimated from corrected r2 information.

Fat-tailed sheep breeds can tolerate periods of negative energy balance without suffering from elevated concentration of plasma non-esterified fatty acid (NEFA). This ability was attributed to unique metabolism of fat-tailed adipose depot, whereas role of liver as an influential organ in fatty acid metabolism was not evaluated yet. Hence, current study was conducted to evaluate the effects of negative and positive energy balances on liver expression of genes related to fatty acid metabolism in fat-tailed and thin-tailed lambs.

Background: Identification of genomic regions that have been targets of selection may shed light on the genetic history of livestock populations and help to identify variation controlling commercially important phenotypes. The Azeri and Kuzestani buffalos are the most common indigenous Iranian breeds which have been subjected to divergent selection and are well adapted to completely different regions. Examining the genetic structure of these populations may identify genomic regions associated with adaptation to the different environments and production goals.

This study aimed to evaluate the effects of negative and positive energy balances on gene expression of regulators and enzymes controlling lipogenesis and lipolysis in muscle and adipose depots of fat-tailed and thin-tailed lambs. Lambs were slaughtered during neutral, negative and positive energy balances for sample collection. Real time q-PCR was conducted to measure the gene expression.

Chicken is a dual-purpose animal important from both agricultural and medical aspects. Even though significant improvements have been made in chicken transgenesis technologies, chicken genome manipulation has not been widely used in developmental biology. This study was aimed to evaluate chicken egg white nuclease properties and thereof plausibility of devising an in vivo transfection technology without causing physical damage to the embryo.
