این آزمایش طی سال زراعی1387-1386، به منظور بررسی تطبیقی مراحل رشدی گندم و جودره جهت مدیریت بهتر آنها، در مزرعه تحقیقاتی موسسه تحقیقات گیاهپزشکی در ورامین انجام گرفت. جودره و گندم رقم کویر در مجاورت یکدیگر در قالب طرح بلوک کامل تصادفی با چهار تکرار کاشته شدند. مراحل فنولوژی بر اساس مقیاس زادکس و تجمع واحدهای حرارتی بر حسب درجه روز رشد برای هر مرحله از رشد ثبت گردید. نتایج نشان داد که جودره مراحل...
The conidiation process of Neurospora crassa is characterized by three morphogenetic steps: hyphal adhesion, aerial hyphal formation, and production of conidia. Previous data indicated the occurrence of a hyperoxidant state at the onset of all three morphogenetic steps. Because glutamine synthetase (GS) and the biosynthetic glutamate dehydrogenase [GDH(NADP)] enzymes are susceptible to inactiva...
Amino acid conversion to aroma compounds by Lactococcus lactis is limited by the low production of alpha-ketoglutarate that is necessary for the first step of conversion. Recently, glutamate dehydrogenase (GDH) activity that catalyzes the reversible glutamate deamination to alpha-ketoglutarate was detected in L. lactis strains isolated from a vegetal source, and the gene responsible for the act...
The gynogenetic diploid hybrid clone line (GDH) derived from red crucian carp (♀ RCC) × common carp (♂ CC) possesses the unusual reproductive trait of producing unreduced diploid eggs. To identify the mechanism underlying this phenomenon, we examined the structure, in vivo developmental process and in vitro dynamic development of the GDH gonad. In summary, compared with RCC and CC, GDH showed c...
Glutamate (Glu) dehydrogenase (GDH, EC 1.4.1.2-1.4.1.4) catalyzes in vitro the reversible amination of 2-oxoglutarate to Glu. The in vivo direction(s) of the GDH reaction in higher plants and hence the role(s) of this enzyme is unclear, a situation confounded by the existence of isoenzymes comprised totally of either GDH beta- (isoenzyme 1) or alpha- (isoenzyme 7) subunits, as well as another f...
BACKGROUND Giardia duodenalis is a common intestinal parasite that infects humans and many other mammals, mainly distributing in some areas with poor sanitation. The proportion of the human giardiasis burden attributable to G. duodenalis of animal origin differs in different geographical areas. In Mainland China, genetic data of the gdh and bg genes of G. duodenalis from animals are only limite...
The mechanism of insulin dysregulation in children with hyperinsulinism associated with inactivating mutations of short-chain 3-hydroxyacyl-CoA dehydrogenase (SCHAD) was examined in mice with a knock-out of the hadh gene (hadh(-/-)). The hadh(-/-) mice had reduced levels of plasma glucose and elevated plasma insulin levels, similar to children with SCHAD deficiency. hadh(-/-) mice were hypersen...
The incidence of Clostridium difficile infection (CDI) has risen almost 3-fold in the United States over the past decade, emphasizing the need for rapid and accurate tests for CDI. The Cepheid Xpert C. difficile assay is an integrated, closed, nucleic acid amplification system that automates sample preparation and real-time PCR detection of the toxin B gene (tcdB). A total of 432 stool specimen...
Background: Freshwater turtles, Trachemys scripta elegans, are one of the few vertebrate species capable of surviving prolonged periods without oxygen. Anoxic survival requires numerous physiological and biochemical changes, including a drastic reduction in metabolic rate, a cessation of oxygen-based metabolism, and a suppression of urea-synthesis. Given this state, the purpose of this study wa...
Ion mobility (IM) and tandem mass spectrometry (MS/MS) coupled with native MS are useful for studying noncovalent protein complexes. Collision induced dissociation (CID) is the most common MS/MS dissociation method. However, some protein complexes, including glycogen phosphorylase B kinase (PHB) and L-glutamate dehydrogenase (GDH) examined in this study, are resistant to dissociation by CID at ...
