Objective(s):[p1]  This study highlights xylanase overproduction from Bacillus mojavensis via UV mutagenesis and optimization of the production process. Materials and Methods:Bacillus mojavenis PTCC 1723 underwent UV radiation. Mutants’ primary screening was based on the enhanced Hollow Zone Diameter/ Colony Diameter Ration (H/C ratios) of the colonies in comparison with the wild strain on Xyla...

In order to investigate the effect of saline irrigation water and potassium spraying treatments on the yield and photosynthetic assimilate partitioning coefficient, a study was conducted in 2014 in the form of split factorial experiment in a randomized complete block design with four replications at Rudasht Salinity and Drainage Research station in Isfahan, central Iran. Irrigation water treatm...

A Sigma factor gene which is important in the global regulation of heat shock responses in prokaryotes, rpoH, was isolated from Flexibacter chinesis by PCR, sequenced and compared to the rpoH genes of a variety of other organisms. The rpoH gene was 98% similar to other previously characterized genes. A mutant of rpoH was produced (JR102) which had a reduced growth rate at both low and high temp...

genetic diversity amongst 21 induced mutant clones tolerant to salinity along with one non-irradiated sensitive clone of banana (musa acuminata cv. dwarf cavendish (aaa)) were studied using morphological and random amplified polymorphic dna (rapd) markers. out of the 30 phenotypic indices screened, 23 were polymorph and two traits, leaf habit and blotches color, were differentiated by non-irrad...

Background: Recombination Activating Genes (RAG) mutated embryonic stem cells are (ES) cells which are unable to perform V (D) J recombination. These cells can be used for generation of immunodeficient mouse. Creating biallelic mutations by CRISPR/Cas9 genome editing has emerged as a powerful technique to generate site-specific mutations in different sequences. Ob...
