Comparative assessment of metabolic, ionic and molecular responsiveness of four facultative halophytes to habitat salinization in the southwest of Jeddah Governorate, Saudi Arabia
This study explores the influence of salinity on some physiological and biochemical pathways of four facultative halophytes (Abutilon pannosum, Indigofera oblongifolia, Senna italica, and Tetraena coccinea) along the southwest coast of Jeddah Governorate. Through a comparative analysis of these plants in both saline and non-saline environments, the study investigates chlorophyll levels, ion concentrations within the plants, the correlation with the SOS1 gene, and the impact of salinity on metabolic compounds. The overarching goal is to gain insights into the adaptive mechanisms of these specific plants to salt stress, prov...

Increasing the meat productivity of young sheep based on the use of the gene pool of the Dorper and Hissar breeds
This study aims to assess the efficacy of integrating Dorper and Hissar rams into the breeding program of Kazakh fat-tailed coarse-haired ewes for generating young mutton. The research involved forming three groups, each comprising 40 ewes of the Kazakh fat-tailed coarse-haired breed, based on analog pairs. Ewes in Group I were inseminated with Dorper ram semen, those in Group II were inseminated with Hissar ram semen, and Group III served as a control with purebred Kazakh fat-tailed coarse-haired sheep breeding. Results revealed that crossbred rams in Group II achieved a significantly higher live weight of 45.2 kg at 120 ...

Micromorphological characterization and electron microscopic study of parasitic species of the family Loranthaceae Juss
In this study, cluster dendrogram (CD), principal component analysis (PCA) and analysis of variance (ANOVA) were used to evaluate the ability to discriminate Loranthaceae species using micromorphological characteristics. Most of the micromorphological characteristics of the leaf and fruit surfaces used reflected significant variation between the species of Loranthaceae. The type of stomata, trichome, lenticels, fine relief of the cell wall and wax form were the most taxonomically important characteristics. In addition, the cluster dendrogram of morphological characteristics showed species distribution within branches based...
