The liver fluke, Fasciola hepatica, is considered as the most common cause of fasciolosis in both domestic livestock and human. This study was carried out to detect the prevalence of the larval stages of F. hepatica in the snails Galba truncatula and Lymnaea stagnalis in West Azarbaijan, Iran. Snail collection was performed through searching 28 freshwater habitats from May to December 2010. Fol...
Antimicrobial activity of certain species Lactobacillus bacteria were known to produce a type bacteriocin called Plantaricin (Pln). In this study, the PlnF (plnF) gene (666 bp) encoding plantaricin was synthetically constructed based on sequence predefined and valuable amino acid compositions subcloned into pET-28 (+) expression vector. Thereafter transformation recombinant vector BL21 (DE3) co...
Background and aim: Newcastle disease (ND) is one of the most serious diseases among many species of birds and causes devastating effects on the poultry industry. This disease is endemic in Iran and ND outbreaks occur unexpectedly and with high mortality and severe clinical signs. The sequence of the F protein cleavage site is that the major virulence determinant of Newcastle disease virus (NDV...
Background and aim: Induction of fetal hemoglobin (Hb-F) can improve the patients’ symptoms of haemoglobinopathies. Several factors can induce gamma globin gene expression and increased Hb-F levels in patients. In this study, the expression of genes is involved in regulation of gamma globin synthesis such as PIPKII-alpha BCL11a, and miR-30a during CD34+ hematopoietic stem cell differentiation i...
Nowadays, genetic engineering methods are able to reduce the time of breeding programs for improvement of fruit trees, as well as offering a focused breeding system. The purpose of the present investigation was to study the factors that affect Agrobacterium tumefacience mediated transformation of two pear cultivars: Bartlett and Harrow Delight. Two explants (leaves and axillary shoot meristems)...
Newcastle disease (ND) is one of the contagious viral diseases in avian species. Recently, several ND outbreaks in pigeon caused by pigeon paramyxovirus serotype-1 (PPMV-1) have been reported in limited numbers from Iran and phylogenetic studies have been conducted on partial sequence of NDV fusion (F) gene. In the present study, ten PPMV-1, named Pigeon_paramyxovirus1_isolate_pigeon/Iran/UT_EG...
Loss of Chloroplast trnLUAA Intron in Two Species of Hedysarum (Fabaceae): Evolutionary Implications
Previous studies have indicated that in all land plants examined to date, the chloroplast gene trnLUAA isinterrupted by a single group I intron ranging from 250 to over 1400 bp. The parasitic Epifagus virginiana haslost, however, the entire gene. We report that the intron is missing from the chloroplast genome of twoarctic species of the legume genus Hedysarum (H. alpinum, H. ...
HIGHLIGHTS • Molecular analysis of aurofusarin biosynthesis in F. culmorum. Mycelial pigmentation depending on gene expression and accumulation. Pigmentation variations growth phase.
Background and Objective: Secretory extracellular Phospholipases are generally involved in hydrolysis of extracellular phospholipids and thus providing nutritive source of carbon, nitrogen, and phosphate. However, intracellular phospholipases perform metabolic functions and adjust biologic activities. Synthesis of phospholipases in different pathogenic microorganisms and their mode of action in...
