The aim of the present study was to identify the deletion/insertion polymorphism of the bovine prion protein gene (PRNP) within the promoter sequence (23 bp), intron 1 (12 bp) and 3' untranslated region (14 bp). DNA was isolated from blood of 234 randomly tested Polish Holstein-Friesian cows and from semen of 47 sires used for artificial insemination (AI) in 2004. No statistically significant differences were found in the frequency of genotypes and alleles between cows and breeding bulls in the 3 analysed polymorphic sites within the PRNP gene. Only 3 haplotypes were identified in sires and 4 haplotypes in cows.

Background: SARS-CoV-2 responsible for the COVID-19 pandemic, infiltrates the human body by binding to the ACE2 receptor in the respiratory system cell membranes, leading to severe lung tissue damage. An analog of ACE2, ACE1, has gained attention due to its well-known Deletion/Insertion (D/I) polymorphism, which seems to be associated with COVID-19 outcomes. This study aims to reveal the allelic and genotypic frequencies of the rs4646994 polymorphism in the Moroccan population and investigate the association between COVID-19 outcomes and both genotypic and demographic data.

Sugarcane is an economically important polyploid crop whose genetic complexity and limited fertility poses a challenge for crop improvement programs. Gamma radiation-induced mutagenesis is an alternate approach for generating a diverse array of agronomically useful mutants, accelerating varietal development in a long-duration crop like sugarcane. To develop agronomically useful mutants of a commercial sugarcane genotype Co 99004, gamma ray induced in vitro mutagenesis was carried out.

Insertion/deletion polymorphisms, or InDels, are widely present in the human genome. They have been considered as potential markers for forensic analysis because they can be genotyped using the CE platform and compatible typing techniques used in forensic laboratories. Additionally, InDels have lower mutation rates and often short amplicon sizes, making them ideal for detecting degraded samples.

Background: The overexpression of efflux pumps (Eps) was reported to contribute to multidrug resistant tuberculosis (MDR-TB). Increases in Eps that expel structurally unrelated drugs contribute to reduced susceptibility by decreasing the intracellular concentration of antibiotics. In the present study, an association of mycobacterial membrane protein (MmpS5-MmpL5) Ep and its gene regulator (Rv0678) was investigated in MDR-tuberculosis isolates.
