Genetic Effect Of The Dwarfing Genes On Some Culm Characteristics Associatcd With Lodging Resistance In Bread Wheat, Md. Mahbub Hasan
Genetic Effect Of The Dwarfing Genes On Some Culm Characteristics Associatcd With Lodging Resistance In Bread Wheat, Md. Mahbub Hasan
Md. Mahbub Hasan
Due to the challenge of screening traits related to lodging resistance under natural field conditions, selection for lodging resistant varieties in wheat breeding programs is difficult. The identification of easily measurable culm anatomical traits related to lodging resistance would simplify the selection process. The present study was conducted to determine the effect of dwarfing genes on culm anatomical traits related to lodging resistance in our of basal internode 1. Field and laboratory study was conducted in Shahjalal University of Science and Technology, Sylhet, Bangladesh with eight wheat genotypes having Rhr1, Rht2 dwarfing genes in them and a local land race …

Graduate Theses and Dissertations
We used variable number tandem repeats (VNTR) to validate the chicken as a human medical model for Pulmonary Arterial Hypertension. We identified seven regions on four chromosomes and interrogated for VNTR markers that significantly associate with Pulmonary Hypertension Syndrome/ascites. In those regions, we identified 7 candidate genes; AGTR1, ACE, p38MAPK, SST, 5HT2B, NET1, and CALM3 for further analysis as significantly contributing QTL for ascites/PHS. We also used variable number tandem repeats to measure gene flow and gather evidence for multiple paternity in a population of Timber rattlesnakes, Crotalus horridus. We were able to verify 1 VNTR that can be used …

In addition to providing the molecular machinery for transcription and translation, recombinant microbial expression hosts maintain the critical genotype-phenotype link that is essential for high throughput screening and recovery of proteins encoded by plasmid libraries. It is known that Escherichia coli cells can be simultaneously transformed with multiple unique plasmids and thusly complicate recombinant library screening experiments. As a result of their potential to yield misleading results, bacterial multiple vector transformants have been thoroughly characterized in previous model studies. In contrast to bacterial systems, there is little quantitative information available regarding multiple vector transformants in yeast. Saccharomyces cerevisiae is the …

Animal development is remarkably robust; cell fates are specified with spatial and temporal precision despite physiological and environmental contingencies. Favorable conditions cause Caenorhabditis elegans to develop rapidly through four larval stages (L1-L4) to the reproductive adult. In unfavorable conditions, L2 larvae can enter the developmentally quiescent, stress-resistant dauer larva stage, enabling them to survive for prolonged periods before completing development. A specific progression of cell division and differentiation events occurs with fidelity during the larval stages, regardless of whether an animal undergoes continuous or dauer-interrupted development. The temporal patterning of developmental events is controlled by the heterochronic genes, whose products …

A method is proposed that finds enriched pathways relevant to a studied condition using the measured molecular data and also the structural information of the pathway viewed as a network of nodes and edges. Tests are performed using simulated data and genomic data sets and the method is compared to two existing approaches. The analysis provided demonstrates the method proposed is very competitive with the current approaches and also provides biologically relevant results.

Role Of Cyp2a5 In Drug Metabolism, Chemical Toxicity, And Maintenance Of Steroid Hormone Homeostasis : Insights From Studies On A Novel Cyp2a5-Null Mouse Model, Xin Zhou
Legacy Theses & Dissertations (2009 - 2024)
The central hypothesis is that CYP2A5 plays an important role in the metabolism of xenobiotic substrates, and in the toxicity induced by over-exposure to drugs, as well as in the metabolism of endogenous compounds and regulation of steroid hormone homeostasis. The specific aims are: 1) to generate and characterize a Cyp2a5-null mouse; 2) to determine the role of CYP2A5 in the systemic clearance of nicotine and cotinine; and 3) to explore the mechanisms underlying the resistance of the lateral nasal gland (LNG) of male Cyp2g1-null/Cyp2a5-low mouse and Cyp2a5-null mouse to acetaminophen (AP) toxicity.

The receptor protein tyrosine kinases (RPTKs) and the non- receptor protein tyrosine kinases (PTKs) are among the most commonly up-regulated genes found in all types of cancers. Although, a large body of data implicates a majority of tyrosine kinases (TKs) in cancer, few have been extensively evaluated for any potential therapeutic benefit in any of the many subtypes of breast cancer. We have used RNA interference (RNAi) to perform a large-scale loss-of-function analysis to facilitate the identification of individual factors necessary for the survival of an ErbB2 positive breast cancer cell line. We have found that 30% of the TKs …
