Taxonomic status of the black porgy, Acanthopagrus schlegelii (Perciformes: Sparidae) inferred from mitochondrial genes
The black porgy Acanthopagrus schlegelii (Bleeker, 1854) is a commercially important fish distributed in estuarine and coastal waters of the west Pacific Ocean. Based on body color pattern, two subspecies A. schlegelii schlegelii (dark-unicolored specimens) and A. schlegelii czerskii (striped specimens) were suggested by some taxonomists. However, due to the morphology...

Breeding potential of the basmati rice germplasm under water stress condition
Eight parents were selected on the basis of phenotypic and genotypic screening for the development of F1. All the possible combinations were made between the parents excluding reciprocals in diallel mating design. Data were analyzed by using Hayman graphical approach and Griffing’s approach to study the genetics of the parents and their F1 hybrids. Based on the genetic component analysis, both...

Genetic diversity among Toxoplasma gondii isolates from different hosts and geographical locations revealed by analysis of ROP13 gene sequences
Toxoplasma gondii can infect almost all the warm-blooded animals and human beings, causing serious public health problems and economic losses worldwide. Rhoptry protein 13 (ROP13) plays some roles in the invasion process of T. gondii. In this study, sequence variation in ROP13 gene among 14 T. gondiiisolates from different geographical locations and hosts was examined. The...

Regeneration of Algerian Citrus germplasm by stigma/style somatic embryogenesis
Stigma/style somatic embryogenesis is one of the efficient methods in plant regeneration of most Citrus ssp., without inducing somaclonal variations. Furthermore, somatic embryogenesis from style/stigma proved to be effective in the elimination of the main citrus virus and virus-like diseases. This technique was applied on Algerian citrus collection. Different Citrus species [Citrus...

Ultrastructural changes of tomatoes (Lycopersicon esculentum) root colonized by Glomus mosseae and Ralstonia solanacearum
The colonization of plant root cell by mycorrhizal fungi is one of the mechanisms involved for the understanding of plant bio-protection against soil-borne pathogens. The aim of current study was to investigate and describe tomato (Lycopersicon esculentum) root ultra-structural modifications caused by Glomus mosseae and the bacterial wilt Ralstonia solanacearum. In scanning electron microscopy...

The effect of NaCl stress on the germination of seed and growth of wild species and cultivated varieties of tomato
In this study, a cultivated species (Lycopersicon esculentum 'Moneymaker') and asalt-tolerant wild species of tomato (Lycopersicon pimpinellifolium 'PI365967') wereused to study growth characteristics within solutions of varying NaCl concentrations.Results show that the germination rates of PI365967 and Moneymaker were 100%under concentrations of 0 mmol/L NaCl. The germination of both types of...

Comparative nutritional analysis between Vigna radiata and Vigna mungo of Pakistan
Vigna radiata (mung bean) and Vigna mungo (mash bean) of the family Fabaceae are among staple food in Pakistan. The experiments were conducted on these beans to determine the proximate composition such as moisture, ash, fibre, fat and protein content. The protein isolates from V. radiata and V. mungo was prepared and their functional properties (foaming, nitrogen...

Effects of carbon levels on shoot growth and root characteristics of different kenaf (Hibiscus cannabinus L.) varieties grown on sandy bris soil
The effects of carbon levels on shoot growth and root characteristics of five kenaf varieties were assessed in a shade house experiment. The kenaf plants were grown in pots containing sandy beach ridges interspersed with swales (BRIS) soil. Organic carbons at levels of 0, 10, 20 and 30 t ha-1 were applied to pots using organic fertilizer. The plants at carbon levels 20 t ha-1 had the highest plant...

Identification and molecular analysis of mercury resistant bacteria in Kor River, Iran
Mercury (Hg) is one of the most important toxic pollutants widespread in the environment. It is being extensively used in industrial applications (chlor-alkali electrolysis, fungicides, disinfectants, dental products, etc), resulting in local hot spots of pollution and serious effects on biota and humans. The aim of this study was to identify mercury resistant bacteria and extract their plasmids and...

Application of new physical storage technology in fruit and vegetable industry
With the development of science and technology, consumers not only require food to be safe, but also require them to keep the original natural flavor and nutritional value as well, while the traditional chemical storage method has been increasingly unable to satisfy consumers’ demand. When compared with chemical method, physical technology has more obvious advantage. This article introduces...

Studies on bioactive peptide from Chinese soft-shelled turtle (Pelodiscus sinensis) with functionalities of ACE inhibition and antioxidation
This paper dealt with a novel anti-hypertensive collagen peptide from Chinese soft-shelled turtle (Pelodiscus sinensis), which was an efficient inhibitor of angiotensin converting enzyme (ACE, EC 3.4.15.1). ACE plays an important physiological role in the regulation of blood pressure by virtue of the rennin angiotensin system. In traditional Chinese medicine, Chinese soft-shelled turtle possesses...

Production of bioethanol through enzymatic hydrolysis of potato
Due to gradual decrease in petroleum resources and impacts of these wastes on the environment, there is a need to utilize the wastes of potatoes to get wealth out of wastes and clean the environment. In this study, potato wastes were investigated as source of bioethanol. 100 g potato powder was mixed with 1 L distilled water in two separate beakers to form potato slurry. Bioethanol production was...

Amplification of real-time high resolution melting analysis PCR method for polycystic kidney disease (PKD) gene mutations in autosomal dominant polycystic kidney disease patients
PKD1 and PKD2 are the two genes responsible for the development of autosomal dominant polycystic kidney disease (ADPKD). PKD1 gene mutations accounts for ≈85% of all ADPKD cases, while the remaining ≈15% of cases is caused by mutations in the PKD2 gene. Genotyping for PKD1 and PKD2 mutations was usually identified using conventional polymerase...
