Olea is a genus of about 40 species in the Oleaceae family distributed in warm temperate and tropical areas of southern Europe, Africa, southern Asia, and Australia. The study aimed to use the variations in the Internal Transcribed Spacer 1 (ITS1) region to construct a phylogenetic tree for 12 Iraqi olive varieties with 15 ITS1 sequences downloaded from the NCBI database. Leaf samples were collected from 12 olive varieties grown in five geographical regions of the north of Iraq. Using the BLAST algorithm, 12 sequences were manually adjusted by chromatogram comparison and aligned with the NCBI GenBank database. Haplotype diversity ranged from zero in the Australian population to one in the Moroccan and Spanish populations. Nucleotide diversity ranged from 0.0 in the Australian population to 0.08 in the Algerian population and Tajima's D value was −0.940. Genetic differentiation values ranged from 0.0177 between Iraqi Moroccan and Iraqi Spanish populations to 0.6540 between Iraqi and Algerian populations. The average pairwise nucleotide diversity within populations was 0.9036 in Iraqi and Turkish olive populations to 0.8671 in Iraqi and Algerian populations. The phylogenetic tree formed 2 main clusters. The first cluster includes all Algerian varieties and the Iraqi varieties are grouped in second cluster. The negative Tajima test value in all populations indicates an excess of rare alleles. The high value of gene flow between the Iraqi and Australian populations may have been mediated by human transport and these varieties may have been originated from the same geographical region.

THE OLIVE (Olea europaea L.) is a member of the Oleaceae family, which includes approximately 30 genera and 600 species. In this study collected 88 leaf samples from 17 olive varieties from five geographical regions in Iraq. The Deoxyribonucleic acid (DNA) was extracted from 17 varieties. The DNA samples were analyzed by polymerase chain reaction (PCR) using 9 microsatellite (SSR) primers (DCA7, DCA9, DCA11, DCA16, DCA18, EMO90, GAPU71A, GAPU71B, and GAPU103). For statistical analysis, Power Marker v.3.25 was used to assess different molecular genetics parameters. Mega software was used to generate a phylogenetic tree. The size of the alleles ranged from 91 bp in DAC11 to 245/270 bp in DAC9. The computed mean number of allele was 44.33, and the allele frequency was 0.0892. The observed heterozygosity was 0.2577, with heterozygosity 0.258. Cluster analysis of the total 9 microsatellite markers was used to study the genetic relationships among the 88 different olive genotypes, and they were divided into two main clusters and five sub-clusters. The local cultivars and the foreign cultivar shared the same SSR alleles and they were genetically similar. There were small molecular variations (1%) among the studied geographical regions. The study aimed to investigate the genetic connections among these cultivars and offer valuable insights that can guide forthcoming efforts in cultivation expansion and breeding initiatives.

Introduction: The rapid and recent rise in the pandemic of cardiovascular disease implies that the environment plays a significant role. Numerous biological systems, such as the cardiovascu-lar, blood-forming organs, liver, and kidneys, can be affected by gasoline and smoking. Because filling station employees, repair service workers, gasoline truck drivers, and refinery workers are all at a greater risk of being exposed to gasoline fumes. Even though gasoline and smoking have been investigated for so many years, few studies have looked into the effects of gasoline exposure combined with smoking on a variety of physiological mechanisms. As a result, we propose that combining gasoline exposure with smoking is a risk factor for cardiovascular dis-eases and impaired hepatic function. Methods: To take this theory to the test, the levels of cholesterol, HDL4, LDL-C, triglyceride, and VLDL were measured, as well as for liver enzymes ALP, AST, ALT, indirect bilirubin, direct bili-rubin, and total bilirubin were measured. Results: Our data suggest that smoking with gasoline exposure causes an increase in total and bad cholesterol levels, as well as a significant shift concerning the control group in lipid profile and liver enzymes. the exposed group had higher levels of ALP, and AST and significantly in-creased. In the nonsmoker exposed group D-bilirubin decreased in comparison to the control and exposed smoker group. Conclusion: This research concluded that the liver enzymes (ALP, AST, ALT) were higher among workers who smoke and are exposed to gasoline than in control subjects, similarly, the bad cho-lesterol also increase. Therefore, people who smoke and are handled with gasoline are at a high-er risk of having heart and hepatic diseases. Keywords: Bilirubin, Cardiovascular, Cholesterol, Gasoline, Hepatoxicity.

Background and objectives: North central Middle Eastern countries Iran, Iraq, Turkey, and Syria all have persistent Kurdish regions. Over thousands of years, several ethnicities have immigrated, settled, or resided in the region, including Turks, Persians, Arabs, Kurds, Armenians, Assyrians, Chechens, and Azeris. The aim of the present study is to use a set of Y-STR to characterize the genetic structure of the Kurd, Assyrian, and Armenian population and build a phylogenetic tree among them. Methods: Eleven Y-chromosome STRs were evaluated in a total of 90 unrelated males from the Kurds, Armenians, and Assyrians populations in the Kurdistan region of Iraq (DYS19, DYS390, DYS393, DYS426, DYS437, DYS439, DYS447, DYS460, DYS461, DYS481, and DYS576). Using a DNA extraction kit, total DNA was isolated from leukocytes. PCR products were run on 8% polyacrylamide gel with a 50bp ladder as DNA marker to size the bands, and silver staining was used to identify the DNA bands. Power Marker V3.25 software was used to determine variety of genetic parameters, including total allele number, allele frequency, gene diversity, polymorphic information content (PIC), and phylogenetic tree was constructed by MEGA-X software. Results: The total number of alleles identified in the three populations was 380. The sizes of the alleles ranged from 87bp to 275bp.TofheSemiticmost diverselanguagesloci w.ere DYS447Armeniansand DYS576are a (GD:culturally0.949), whereas DYS426 showed the least diversity (GD:0.896). The Phylogenetic tree divided the populations into two main clusters; The Kurdish and Armenian clades in one cluster and the Assyrian in another cluster. Few of dendrogram leaves from the three examined groups were admixed with each other. Conclusions: This study confirms the high-resolution Y-STR typing's ability to discriminate. It concludes that the genetic distance between Kurd and Armenians is less than the genetic distance between the Kurd and the Assyrians, meaning that the Armenians population are genetically closer to the Kurds population.

Glyphosate is a broad-spectrum herbicide used mostly in crops. This study looked at the genotoxic and Glyphosate has a cytotoxic effect on Allium cepa. As toxicity markers, the Mitotic index, chromosomal aberrations, formations of Micronucleus, germination percentage, root duration, and seed weight were used. Allium cepa seeds were afflicted with distinct concentrations (0.5, 1.0, 2.0 and 4.0 ml/l) of Glyphosate for 24 h treatment periods. The results reveal that pesticide Glyphosate is capable to reduce root growth and causes chromosomal aberrations; consisting of an anaphase bridge, ring chromosome, binucleated cells, multipolarity, Fragment chromosome, vagrant chromosome, chromatid gaps, star anaphase. With increasing Glyphosate concentration, the mitotic index decreased rapidly. In conclusion, our findings indicate that used pesticide may be toxic to living organism.

Wheat (Triticum spp.) is one of the most important cereal crops in Iraq and the world. It includes many species and varieties. The two major cultivated species of wheat are, durum wheat (Tritium durum Desf.) which is tetraploid (2n= 28) and the common wheat (Triticum aestivum L.) which is hexaploid (2n = 42). Ten wheat varieties from both species were examined using ten Simple sequence repeat (SSR) markers (WMC17, WMC20, WMC21, WMC24, WMC25, WMC48, WMC50, WMC283, Xgwm11 and Xgwm626). Various genetic parameters were calculated using Power Marker V3.25 software. A total of 156 alleles were detected in both species. The gene diversity in wheat varieties from both species collectively varied from 0.85 to 1.00, which indicates considerable genetic diversity in the examined varieties. All markers used in this study were highly informative and the polymorphic information content (PIC) values were higher than 0.50 in all loci. Hence all markers are considered useful for genetic diversity studies in wheat’s populations. The dendrogram separated the populations into two main clades and many subgroups. Azadi variety was simplicifolious. This study confirms the discriminating power of SSR typing and its usefulness for comparison within hard and soft wheat populations.
