    An Asian Indian Student\u27s Identity: Living in Two Worlds

    Using narrative inquiry, I tell the story of an Asian Indian student attending a large mid-Atlantic university who approached me in the summer of 2002 for my master\u27s thesis interview. She was an Indian by birth who was adopted by White parents when she was an infant. She had not been to India since. Her story provided me with rich insights into her life including her childhood, identity formation, relationships with her adoptive parents and siblings, and social interactions outside home while attending school. I came to understand issues of meaning-making of her life and sub-culture through her story. I use narrative inquiry as a way to represent her story

    Madhubani Art: A Journey of an Education Researcher Seeking Self-Development Answers through Art and Self-Study

    This study is situated within a self-study research methods course to scaffold doctoral students’ explorations of the intersections of their culture, and research interests using arts as a tool. Embracing the arts as a research method, the first author painted a self-portrait using the vibrant colors of Madhubani art which holds cultural significance to her. She utilized Blumer’s (1986) and Mead’s (1934) theory of symbolic interactionism to explain the process of her self-development as a researcher. Combining her self-portrait with an earlier research study proved valuable as a conduit for understanding and interpreting her work as a research methodologist. This study is valuable to others interested in studying their practice and research identity through an arts-based research metho

    Organophosphorus based pesticides are chemical pesticides which are widely used in India for controlling the pests, insects and plant pathogens. The mode of action of pesticides belonging to this class is on neurotransmitter inhibition as well as muscle suppression by which the target organisms are killed. But since the use of these pesticides is in an uncontrolled and indiscriminate manner in agriculture sector, there is a need to degrade them to protect their harmful effects on environment. Biological degradation of these pesticides areconsidered as better alternatives as this method is both economical as well as eco-friendly. Bioremediation of organophosphorus pesticides inthevicinity of soil has gained much attention recently because the microbes involved in this process are naturally having the potency to degrade the pesticides in their habitat which is called principle of infallibility. This property was explored for the biological degradation of pesticides. The microorganisms have a special gene known as organophosphate hydrolase or ‘oph’ whose enzyme product when come into contact with the organophosphorus compounds readily degrades them. This organophosphate hydrolase enzyme is well known for its broad spectrum of substrates hydrolysis activity. This activity was taken as a tool for screening of potent bacteria from agriculture soils towards organophosphorus degradation in the present study. Serial dilutions of the soil samples collected from three different regions of Telanganastate were donetodecline the microbial loadand thenthrough spread plate and streaking techniques, isolated bacterial colonies were obtained. Screening of these colonies for the presence of OPH enzyme was done by mixing the OPDs onto OP medium. After screening for the potent isolates showing OPH enzyme, it is revealed that the potent isolates which were successful in degradation of organophosphorus pesticideChlorantraniliproleindicatedbybacterialgrowtheveninthepresence of pesticide and also due to the presence of ‘oph’ gene which was produced OPH enzyme

    RNA-Seq reveals a xenobiotic stress response in the soybean aphid, Aphis glycines, when fed aphid-resistant soybean

    Partial funding for Open Access provided by The Ohio State University Open Access Fund.Background: While much recent research has expanded our understanding of the molecular interactions between aphids and their host plants, it is lacking for the soybean aphid, Aphis glycines. Since its North American invasion, A. glycines has become one of the most damaging insect pests on this important crop. Five soybean genes for host plant resistance to A. glycines have been identified, but populations of A. glycines have already adapted to overcome these resistance genes. Understanding the molecular interactions between resistant soybean and A. glycines can provide clues to its adaptation mechanisms. Here, we used RNA-Sequencing to compare and contrast A. glycines gene expression when fed resistant (Rag1) and susceptible soybean. Results: Combining results from a previous A. glycines transcriptome, we generated 64,860 high quality transcripts, totaling 41,151,086 bases. Statistical analysis revealed 914 genes with significant differential expression. Most genes with higher expression in A. glycines on resistant plants (N = 352) were related to stress and detoxification such as cytochrome P450s, glutathione-S-transferases, carboxyesterases, and ABC transporters. A total of 562 genes showed lower transcript abundance in A. glycines on resistant plants. From our extensive transcriptome data, we also identified genes encoding for putative salivary effector proteins (N = 73). Among these, 6 effector genes have lower transcript abundance in A. glycines feeding on resistant soybean. Conclusions: Overall, A. glycines exhibited a pattern typical of xenobiotic challenge, thereby validating antibiosis in Rag1, presumably mediated through toxic secondary metabolites. Additionally, this study identified many A. glycines genes and gene families at the forefront of its molecular interaction with soybean. Further investigation of these genes in other biotypes may reveal adaptation mechanisms to resistant plants
