Background: The methylotrophic yeast Pichia pastoris is an appealing production host for a variety of recombinant, including biologics. In this sense, various genetic- and non-genetic-based techniques have been implemented to improve the production efficiency of this expression platform. Los1 (loss of supression) encodes a non-essential nuclear tRNA exporter in Saccharomyces cerevisiae, which i...

To study nitrogen contribution to cucumber derived from fixation of Paenibacillus polymyxa WLY78. The nif gene cluster deletion mutant (?nifB-V) WLY78 was constructed by a homologous recombination method. effects plant-growth promotion were investigated greenhouse experiments. estimated 15N isotope dilution method (also being called the natural abundance technique). Deletion P. resulted in comp...

Objective: Identity the genetic aspects and major gene influence on energy balance, milk production, fertility, food safety and consumer are the recent interests of genetic and breeding researchers. Methods: Najdi Cattle is the most prominent breeds in Khuzestan province. To do this plan in Shoushtar Najdi Cattle Station, blood samples were taken from 15 Najdi Cattles. DNA was extracted from wh...

Strawberry crown rot is a serious fungal disease that poses great threat to strawberry production in the growth cycle. The dominant pathogens of were different periods. main pathogen at seedling stage unclear. In this study, 74 Colletotrichum spp. isolated from 100 plants stage. Based on morphological observations and phylogenetic analysis multiple genes (ACT, CAL, CHS, GAPDH, ITS), all tested ...

In Bacillus subtilis, motility genes are expressed in a hierarchical pattern – governed by the σD transcription factor and other proteins such as EpsE molecular clutch SlrA/SlrR regulator proteins. contrast, motile species cereus group seem to express their non-hierarchical pattern, less is known about regulation, also given that no orthologs σD, EpsE, SlrA or SlrR found B. genomes. Here we sho...

pelizaeus­-merzbacher-like disease (pmld) is a hypomyelinating leukoencephalopathy disorder with a genetically heterogeneous pattern. mutations in the gja12/gjc2 gene cause one form of autosomal recessive pelizaeus­-merzbacher-like disease. here, we report a new mutation in a ­10-month-old girl with nystagmus, psychomotor delay, hypotonicity, head nodding and dysmyelination from healthy second ...

chronic granulomatous disease (cgd) is a rare primary immunodeficiency disorder due to a genetic defect in one of the components of nicotinamide adenine dinucleotide phosphate (nadph) oxidase complex. this complex is composed of membrane-bound gp91- phox and p22- phox subunits, and cytosolic subunits consisting of p47- phox , p67- phox , and p40- phox . a mutation in cybb gene encoding gp91- ph...

The advanced cloning-free PCR-based allele replacement strategy (Erdeniz et al., 1997) has been followed in the present study. The principle of this strategy is graphically depicted in Figure 1a. In the gene targeting experiment performed in the present study, the uracil auxotrophy (Ura-) of CEN.PK 113-5D strain has been exploited. Thus, cells where the gene targeting substrate integrated corre...
