Identification and characterization of hydrolytic enzymes from the midgut of Sunn Pest of wheat (Eurygaster integriceps)
Ogur, E.; YÜCEL, MUSTAFA; Öktem, Hüseyin Avni (Informa UK Limited, 2009-01-01)
To help in the development of Sunn Pest-resistant transgenic plants employing protease or alpha-amylase inhibitors, midgut hydrolytic enzymes of Sunn Pest (Eurygaster integriceps, Put.) (Heteroptera: Scutelleridae) were identified and characterized biochemically. We observed levels of very low proteolytic activity of trypsin (3 nmoles/min/mg), elastase (0.66 nmoles/min/mg) and leucine aminopeptidase-like (14.4 nmoles/min/mg) proteases, but no chymotrypsin and papain-like activity. Proteolytic activities wer...
Identification and characterization of hydrolytic enzymes of sunn pest (eurygaster integriceps) and cotton bollworm (helicoverpa armigera)
Özgür, Ebru; Öktem, Hüseyin Avni; Department of Biochemistry (2006)
In this study, hydrolytic enzymes from sunn pest (Eurygaster integriceps) and cotton bollworm (Helicoverpa armigera) midguts were identified and characterized in terms of their optimum pH, Km and Vmax values. Hydrolytic activities were also tested for inhibition by several protease and alpha-amylase inhibitors which can be used for the development of insect resistant plants through transgenic technologies. For sunn pest midgut, a low proteolytic activity, belonging mostly to trypsin-like and leucine aminope...
Identification of Free Conducting Particles in Transformer Oils using PD Signals
Anşin, Berfin; Vakilian, Mehdi (2015-01-01)
Transformers are known as one of the most important equipment in power system transmission and distribution network. Safety of transformer insulation is determined mainly by its insulating oil dielectric strength. A major concern which threaten the withstand strength of a liquid insulation is the presence of particle contamination. One of the best methods to detect any abnormality and insulation weakness inside the transformer insulation is based on partial discharge (PD) measurement. Here, to identify the ...
Identification of abiotic stress related MiRNAs in Thellungiella halophila ecotypes
Aysin, Ferhunde; Erson Bensan, Ayşe Elif; Öktem, Hüseyin Avni; Department of Biology (2015)
Environmental stress with climate change currently contributes to approximately 50% of crop loss occurring world-wide. Thellungiella halophila is a plant that is native to highly saline and semiarid environments and exhibits an exceptional ability to tolerate abiotic stress. Primarily, the determination of relatively high GSH/GSSG ratios (glutathione assay), elevated proline accumulation, less MDA (lipid peroxidation) production and increased anthocyanin levels and less reduced RWC of the T. halophila (Shan...
Identification of proteins interacting with tagged-pathogen effector protein in agro-delivered planta
Dagvadorj, Bayantes; Akkaya, Mahinur S.; Günel, Aslıhan; Department of Biotechnology (2012)
Wheat is one of the most essential food sources in the world. However, there has been serious yield loss of wheat production due to stripe rust disease caused by the fungal pathogen Puccinia striiformis f. sp. tritici. The cost-effective and long-lasting defense to the disease can be achieved by generating genetically resistant crops against the disease forming pathogens. To accomplish this, first step is to acquire knowledge in the plant pathogen interactions of the crop and the pathogen of interests at th...
