A peptide-based photoaffinity label for the catalytic subunit of the cAMP-dependent protein kinase was prepared from the amino acid p-benzoyl-L-phenylalanine [L-Phe(pBz)]. By using solid-phase peptide synthesis methodology, DL-Phe(pBz) was incorporated into the cAMP-dependent protein kinase substrate Leu-Arg-Arg-Ala-Ser-Leu-Gly in place of the phosphorylatable serine. The diastereomeric peptide...

Probenazole (3-allyloxy-1,2-benzothiazole 1,1-dioxide, PBZ) is a bactericide and fungicide that acts by inducing plant defense systems. It has been shown to induce the expression of NBS-LRR genes like RPR1 (rice probenazole-response gene) in rice (Oryza sativa L.) and systemic acquired resistance (SAR)-like disease resistance. Two maize (Zea mays L.) genes Zmnbslrr1 (a NBS-LRR gene, cloned from...

The purpose of this study was to determine how two types of sampling data could be used for an exposure assessment in a beryllium shop at the Department of Energy's Rocky Flats Plant. Beryllium exposure was assessed via fixed airhead (FAH) sampling, in which the filter cassette was affixed to the machine, generally within a few feet of the worker's breathing zone. Approximately 500,000 FAH samp...

Cerebral Metabolic Changes During Treatment of Subacute Cerebral Infarction by Alpha and Beta A drenergic Blockade With Phenoxybenzamine and Propranolol • Cerebral hemispheric blood flow (HBF) and metabolism were measured in 30 patients with acute and subacute cerebral infarction before and after intracarotid infusion of the alpha adrenergic blocking agent phenoxybenzamine (PBZ) or the beta adr...

Tef [Eragrostis tef (Zucc.) Trotter] and finger millet [Eleusine coracana Gaertn] are staple cereal crops in Africa and Asia with several desirable agronomic and nutritional properties. Tef is becoming a life-style crop as it is gluten-free while finger millet has a low glycemic index which makes it an ideal food for diabetic patients. However, both tef and finger millet have extremely low grai...

Freezing injury is an important limiting factor in the production of pomegranate in Iran.The aim of the present study was to evaluate the effect of paclobutrazol (PBZ) on cold hardiness of pomegranate (Punica granatum L.) cv. ‘Malas Saveh’. Different concentrations of PBZ including 0 (control), 31, 62, 125 or 250 mg L–1 were sprayed on one-year-old plants in August and the electrolyte leakage o...

The excess of nitrogen (N) causes the overgrowth sweet potato foliage, increasing self-shading and reducing root yield. Therefore, a combined N paclobutrazol (PBZ) application can reduce vegetative benefit purpose this study was to evaluate plant growth, yield, uptake removal by plants fertilized with treated PBZ during two planting seasons. treatments consisted four rates (0, 50, 100 200 kg·ha...
