Heading date in wheat (Triticum aestivum L.) and other small grain cereals is affected by the vernalization and photoperiod pathways. The reduced-height loci also have an effect on growth and development. Heading date, which occurs just prior to anthesis, was evaluated in a population of 299 hard winter wheat entries representative of the U.S. Great Plains region, grown in nine environments dur...
بهاره سازی و فتوپریود نقش قابل توجهی در سازگاری جغرافیایی و عملکرد زراعی بالا و عملکرد بالقوه در غلات دارند. بنابراین اطلاع از وضعیت توزیع ژن های ورنالیزاسیون و فتوپریود برای درک بهتر سازگاری ژنوتیپ های مختلف گندم به محیط های گوناگون خیلی مهم است. اطلاع از تنوع اللی این ژن ¬ها به اصلاح گران نبات کمک می¬کند تا با بینش بهتری با استفاده از نشانگرهای مولکولی در برنامه های اصلاحی برای به حداکثر رسان...
The observation that receptors which mediate their signals through heterotrimeric guanosine triphosphate (GTP)-binding proteins (Gproteins) share a considerable amount of sequence similarity has resulted in the rapid molecular characterization of this receptor superfamily. Moreover, it became clear that several receptor families consisted of more receptor subtypes than originally anticipated fr...
Dopamine, one of main modulatory neurotransmitters of the nervous system acts on target cells through two classes of G protein-coupled receptors, D1 and D2. The two dopamine receptor classes display different structures, interact with different regulatory partners (including heterotrimeric G proteins) and, accordingly, have independent evolutionary origins. In vertebrates, each of these recepto...
Cytokinin oxidase (CKX) plays a crucial role in plant growth and development by reversibly inactivating cytokinin (CTK). Twenty-four primer pairs, designed from ESTs of the TaCKX genes family of common wheat, were used to identify their allelic variations associated with grain size, weight, and filling rate in 169 recombinant inbred lines (RIL) derived from Jing 411 × Hongmangchun 21. TaCKX6a02...
Background: Varnish, when brushed onto the teeth, provides a highly concentrated dose of fluoride and maintains prolonged contact with enamel to inhibit caries. Objective: Our study aims to evaluate the effect of mineralizing fluorine varnish on the progression of initial caries of enamel in temporary dentition by laser fluorescence. Material and Methods: Object of observation. 1 group 100 chil...
The Green Revolution (GR) of the 1960s saw spectacular increases in cereal crop yields, enabled by widespread adoption high-yielding semi-dwarf varieties and increased fertilizer use. Semi-dwarfism is caused mutant wheat Reduced height-1 (Rht-1) rice semi-dwarf1 (sd1) alleles, respectively, which confer harvest index (grain to straw ratio) reduced yield loss from “lodging” (flattening crops win...
L’objectif de cette étude était caractériser la diversité génétique des porcs hybrides (Large White × Landrace) Maxgro en Ukraine. Présentation résultats du typage ADN LLC SPE « Globinsky pig complex ». En utilisant l’analyse PCR-RFLP polymorphisme boucle-D l’ADN mitochondrial, 7 haplotypes mitochondriaux ont été identifiés – C, D, E, G, K, N, O. Dans un échantillon (n=37), concentration déterm...
The in vitro binding properties of enterotoxins of Vibrio cholerae and Escherichia coli to different pure gangliosides and related neutral glycosphin-golipids were analyzed with a sorbent assay utilizing plastic tubes to which the glycolipid substances had been coupled. It was found that the cholera toxin bound to G(M1) ganglioside better than to the other tested substances G(M3), G(M3)-NGN, G(...
Many reports have cited coexpression of platelet-derived growth factor (PDGF) and its receptors by tumor cells or cells supporting tumor growth, suggesting both autocrine and paracrine mechanisms for PDGF-mediated tumor growth. We found that a small organic molecule, N-[4-(trifluoromethyl)phenyl] 5-methylisoxazole-4-carboxamide (SU101, leflunomide), inhibited PDGF-mediated signaling events, inc...
