In plants, nitric oxide synthase (NOS)-like or nitrate reductase (NR) produces nitric oxide (NO), which is involved in releasing seed dormancy. However, its mechanism of effect in potato remains unclear. In this study, spraying 40 μM sodium nitroprusside (SNP), an exogenous NO donor, quickly broke
The IPO (ipomoelin) gene was isolated from sweet potato (Ipomoea batatas cv Tainung 57) and used as a molecular probe to investigate its regulation by hydrogen peroxide (H(2)O(2)) and nitric oxide (NO) after sweet potato was wounded. The expression of the IPO gene was stimulated by H(2)O(2) whether
Several vegetative tissues of potato plants were screened for proteinase activity. Both endopeptidase and exopeptidase activities were investigated using gelatin and L-amino acid-4-nitroanilides (benzoyl-L-arginine-4-nitroanilide/BAPA, glutaryl-L-phenyl-alanine-4-nitroanilide/GLUPHEPA,
Gateways to Clinical Trials is a guide to the most recent clinical trials in current literature and congresses. The data in the following tables have been retrieved from the Clinical Trials Knowledge Area of Prous Science Integrity, the drug discovery and development portal,
The production of biodegradable polymers in transgenic plants in order to replace petrochemical compounds is an important challenge for plant biotechnology. Polyaspartate, a biodegradable substitute for polycarboxylates, is the backbone of the cyanobacterial storage material cyanophycin.
During the spring of 2004 and 2005, angular leaf spot was observed on cucumber (Cucumis sativus L.) in some areas of Kurdistan Province in Iran for the first time. Disease incidence in affected fields was approximately 100%. Symptoms were initially small, round or irregular, water-soaked spots on
Given the importance of the complement anaphylatoxins in cellular recruitment during infection, the ability of secreted products from larval stages of Brugia malayi and Trichinella spiralis to influence C5a-mediated chemotaxis of human peripheral blood granulocytes in vitro was examined. Secreted
Endogenous methylarginines, N(G),N(G)-dimethyl-L-arginine (asymmetric dimethylarginine, ADMA), N(G)-N('G)-dimethyl-L-arginine (symmetric dimethylarginine; SDMA), and N(G)-monomethyl-L-arginine (monomethylarginine; NMMA) are supposed to be produced in human body through the methylation of protein
In this study, the vasodilatory actions of nine edible tropical plant extracts were investigated. Ipomoea batatas (sweet potato leaf), Piper betle (betel leaf), Anacardium occidentale (cashew leaf), Gynandropsis gynandra (maman leaf), Carica papaya (papaya leaf), and Mentha arvensis (mint leaf)
The ability of proteinases in gut extracts of the Indianmeal moth, Plodia interpunctella, to hydrolyze Bacillus thuringiensis (Bt) protoxin, casein, and rho-nitroanilide substrates was investigated. A polyclonal antiserum to protoxin CryIA(c) was used in Western blots to demonstrate slower protoxin
Trypsin PC from the hepatopancreas of the king crab Paralithodes camtschatica was isolated and purified to apparent homogeneity by ion-exchange chromatography on Aminosilochrom and DEAE-Sephadex and affinity chromatography on arginine-agarose. The yield of the enzyme was 37.7%, and the purification
Bacillus subtilis (SH-6) Egyptian strain, isolated from hides, gave the highest protease activity. Luxurious growth and protease production were obtained by the use of a medium containing 8% of potato starch, 0,1 M of ammonium phosphate as carbon and nitrogen sources. Results indicate that borate
