strains of trichoderma harzianum s. l. have a great importance because of affecting mankind by being used as biological control agents against plant pathogens. in the present study, we planned to characterize the phylogenetic structure of t. harzianum recovered from different geographical origins and various habitats in some climates of iran (nc, scd, csw). in order to screen 239 collected tric...

Wheat bread-making quality is mainly determined by glutenin proteins in the grain, which exist in a wide range of variable alleles with differential influence on processing attributes. A recently identified allele, Bx7 over-expression (Bx7(oe) ), has been showing highly significant positive effects on wheat dough strength over the normally expressed Bx7 allele. SDS-PAGE and normal RP-HPLC proce...

PCR amplification and detection of GC rich sequences in DNA is a challenge due to formation secondary structures which resist denaturation, thereby stalling Taq polymerases as well affecting primer annealing. Presently, high fidelity polymerase used for amplifying long GC-rich fragments, while dimethyl sulfoxide (DMSO) has also been suggested an additive Polymerase Chain Reaction (PCR) mix avoi...

background: human leukocyte antigen-g (hla-g) is a non-classical class i molecule highly expressed by extravillous cytotrophoblast cells. due to a single base pair deletion, its function can be compensated by other isoforms. investigating the frequency of null allele in recurrent miscarriage (rm) subjects could be useful in understanding the relationship between frequency of this allele and rm ...

Host plant resistance provided by solid stems has been the most effective means for mitigating wheat stem sawfly (WSS) (Cephus cinctus Norton) damage in spring and winter (Triticum aestivum L.). The trait originates from cultivar “Rescue” is associated with a quantitative locus allele Qss.msub-3BL.b that explains majority of variation solidness. Recently, new Qss.msub-3BL allele, designated Qss...

  Background: Cytochrome P450 2C19 (CYP2C19) is important in metabolism of wide range of drugs. CYP2C19*17 is a novel variant allele which increases gene transcription and therefore results in ultra-rapid metabolizer phenotype (URM). Distribution of this variant allele has not been well studied worldwide. The aim of present study was to investigate allele and genotype frequencies of CYP2C19*17 ...

Background: There are contradictions in the role of genetic variations and food group intake on metabolic syndrome (MetS). This study was aimed at examining the interaction between food groups and CCND2 rs11063069, ZNT8 rs13266634 and MC4R rs12970134 polymorphisms, regarding MetS and its components. Methods: In this matched nested case-control study (2006-2014), the data of 1634 (817 pairs) ca...
