The Evolution and Role of Molecular Tools in Measuring Diversity and Genomic Selection in Livestock Populations (Traditional and Up-to-Date Insights): A Comprehensive Exploration.

Distinctive molecular approaches and tools, particularly high-throughput SNP genotyping, have been applied to determine and discover SNPs, potential genes of interest, indicators of evolutionary selection, genetic abnormalities, molecular indicators, and loci associated with quantitative traits (QTLs) in various livestock species. These methods have also been used to obtain whole-genome sequencing (WGS) data, enabling the implementation of genomic selection. Genomic selection allows for selection decisions based on genomic-estimated breeding values (GEBV).

Expression and Immune Response Profiles in Nile Tilapia () and European Sea Bass () During Pathogen Challenge and Infection.

Nile tilapia () and European sea bass () are economically significant species in Mediterranean countries, serving essential roles in the aquaculture industry due to high market demand and nutritional value. They experience substantial losses from bacterial pathogens and , particularly at the onset of the summer season. The immune mechanisms involved in fish infections by and remain poorly understood.

Isolation and identification of antifungal, antibacterial and nematocide agents from marine bacillus gottheilii MSB1.

Pathogenic fungi employ numerous strategies to colonize plants, infect them, reduce crop yield and quality, and cause significant losses in agricultural production. The increasing use of chemical pesticides has led to various ecological and environmental issues, including the emergence of resistant weeds, soil compaction, and water pollution, all negatively impacting agricultural sustainability. Additionally, the extensive development of synthetic fungicides has adverse effects on animal and human health, prompting the exploration of alternative approaches and green strategies for phytopathogen control.

Performance of Trichogramma evanescens Westwood (Hymenoptera: Trichogrammatidae) on Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) eggs at laboratory and field conditions.

The fall armyworm (FAW), Spodoptera frugiperda (Smith), is a significant pest threatening crops like maize across Africa, necessitating sustainable pest management alternatives. This study evaluates the efficacy of Trichogramma evanescens as a biological control agent against FAW egg masses in Egypt under laboratory and semi-field conditions. FAW larvae were initially collected from infested maize fields and reared on castor-oil plant leaves.
