Indigenous chickens of Jordan are facing extinction and need genetic conservation because they were unable to commercially compete in poultry industry because of low genetic ability ‎compared to commercial layers. The study aimed to investigate phenotypic and genetic diversity ‎of village chickens in the Jordan using discriminant analyses procedure...

The purpose of the study is to determine how geographical proximity, climate, and topography influence the morphology of village chickens in Jordan’s Karak Governorate. Surveys were conducted in six regions of Karak as well as Tafilah, Madaba, Aqaba, and Al-Mafraq governarates. These governarates were included because they are geographically close...

Rice is a staple food that contributes to significant energy intake. Jordan relies on importing to provide the market with the required quantities of rice. Different varieties from different sources with various qualities are available in the market. This study aimed to evaluate the quality of rice available in the markets in Amman city-Jordan. Twe...

Laboratory and greenhouse pot experiments were conducted to assess the allelopathic effects of Artemisia annua water extract on germination and growth of barley. Lower concentrations of A. annua water extract (0.5 and 1.0 %) did not affect the germination of barley seeds. However, higher concentrations (1.5-3.5 %) resulted in significant reductions...

The genetic and phenotypic variability among 22 Jordanian faba bean (Vicia faba L.) accessions were explored. Fifteen horticultural traits were evaluated including Biological weight, Days to flowering, Grain yield, Plant height, Highest lowest pod, Number of primary branches, Pod length, Pod width, Pod weight, days to filling, pod number node-¹, Po...

Genetic diversity of goat breeds in Jordan was investigated using six microsatellite markers (MS). The markers were BM143, CSRD247, INRA40, OARAE54, ILSTS005 and MCM527. The selected goats were predefined into four breeds based on morphological and geographical considerations as Jabali, Dhaiwi, Shami and Sahrawi. The number of alleles, expected and...

Background Genetic diversity of sheep in Jordan was investigated using microsatellite markers (MS). Six ovine and bovine MS located on chromosomes 2 and 6 of sheep genome were genotyped on 294 individual from ten geographical regions. Results The number of alleles per locus (A), the expected heterozygosity (He) and observed heterozygosity (Ho) wer...

This study was carried out to assess the genetic diversity in 48 landraces using eight Amplified Fragment Length Polymorphism (AFLP) primer-pairs. The eight selected AFLP primer-pairs generated a total of 150 polymorphic loci. Using the generated AFLP data, the Un-Weighted Pair Group Method with Arithmetic Average (UPGMA) ordered the genotypes into...

Okra Abelmoschus esculentus L. (Moench), is an economically important vegetable crop grown in tropical and sub-tropical as well as Mediterranean countries. The genome size of the Abelmoschus genus species is still rare. Ploidy determinations have traditionally been done by counting chromosomes of stained root tips, but this method is laborious and...

Phylogeny and evolutionary analyses were performed for Jordan goat breeds based on DNA sequencing. DNA segment of 0.5-kb from sixteen goat individuals of four breeds was sequenced. The DNA sequencing was analyzed by both Arlequin and MEGA softwares. The results showed a quite evolutionary differentiation found within goat breeds between. Furthermor...

Genetic diversity of fat-tailed sheep of Jordan was investigated using microsatellite markers (MS). Six ovine and bovine MS located on chromosomes 2 and 6 of sheep genome were employed for genotyping three flocks in southern region of Jordan. The genetic diversity was evaluated by measuring expected (H-e) and observed (H-o) heterozygosity, Polymorp...

A central enzyme in the proline biosynthesis is the bifunctional enzyme ∆ 1 -pyrroline-5-carboxylate synthase (P5CS) that includes two functional catalytic domains: the γ-glutamyl kinase and the glutamic-γ-semialdehyde dehydrogenase. This enzyme catalyzes the first two steps of the proline biosynthetic pathway and plays a central role in the regula...

The use of insecticides against the cereal leafminer Syringopais temperatella Led. has generally lagged due to cost constraints associated with wheat and barley as low-input crops and the developed insecticidal resistance by the pest. Therefore, this study aimed to investigate susceptibility of wheat and barley varieties commonly grown in Jordan to...

Genetic linkage maps reveal the order of markers based on the frequency of recombination between markers during meiosis. Because the rate of recombination varies along chromosomes, it has been difficult to relate linkage maps to chromosome structure. Here we use cytological maps of crossing over based on recombination nodules (RNs) to predict the p...

Erythrocytes and progenitor-derived erythroblasts of sickle cell anemia patients from the Eastern Province of Saudi Arabia contain increased fetal hemoglobin and G gamma globin. A distinctive DNA polymorphism haplotype in the beta globin gene cluster (++- +-), tightly coupled to a C----T substitution at position -158 5' to the cap site of the G gam...

Patients from the eastern province of Saudi Arabia who have sickle cell anemia have high circulating levels of fetal hemoglobin (hemoglobin F, 17 percent), and they therefore have a mild form of the disease. To examine the molecular basis of the elevated production of hemoglobin F, we searched for mutations in the promoter regions of the two hemogl...

Homozygous sickle cell disease in the eastern province of Saudi Arabia is clinically mild. Circulating fetal hemoglobin levels of 16.0 +/- 7.4% were found in these anemic patients, but only 1.09 +/- 0.97% in their sickle trait parents. To determine whether these sickle cell anemia patients inherit an increased capacity to synthesize fetal hemoglobi...
