Effects Of Cultivars And Fungicides On Foliar Fungal Diseases And Fusarium Head Blight In Winter Wheat, Mahnoor Asif

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Foliar fungal diseases and Fusarium head blight (FHB) are among the major causes of significant yield losses in wheat production, particularly in Nebraska. Resistant cultivars and fungicide applications are common management strategies, but the overuse of fungicides has raised concerns about resistance in Fusarium graminearum populations in Nebraska. This study evaluated the effects of cultivar resistance, fungicide timing and their economic benefits. It also assessed the sensitivity of Nebraska isolates of F. graminearum and F. boothii to a triazole fungicide. In 2022 and 2024, 14 fungicide treatments and a control were arranged in a split-plot experimental design with …

Waking Up Before We Die: Aging And Spirituality, Marcelline Hutton

Zea E-Books Collection

In retirement, I have more time for prayer and reflection, to rest in the Lord, and hence to have my spirit renewed. We choose how we interpret our situations. Positive, spiritual aging ideas enhance our sense of well-being. Of course, the loss of loved ones decreases our sense of self-worth at times, but the Spirit can renew us. As Genesis reminds us, God was still working in the lives of Sarah and Abraham in old age, and they can serve as models for us. Indeed, Sarah laughed at the angels and shows us how humor exists even as we age. …

Insects All Around Us: A Four-Session Bug Club Lesson Plan For Grades 3-5 Covering The Biology And Importance Of Insects In Nebraska, Carolyn Almonte

Honors Program: Senior Projects (Public)

Insects are often overlooked in science curricula when talking about conservation due to the surrounding fear and disgust regarding insects. This disgust not only permeates the mindsets of students, but also teachers, which leads to a hesitance to incorporate an insect-based curriculum or club into a lesson. In response to this, I have created a four-session club curriculum that can be used across four two hour long sessions spread out across four weeks. The goals of this club are: to explain the key traits of insects and arthropods, differentiating the two groups; to explain and define the basic stages of …

Determination Of A New Spring-Flying Species Of The Pterourus Glaucus Complex (Papilionidae) In Southern New England, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The Pterourus glaucus complex in three southern New England states is analyzed for cryptic speciation. What was historically considered to be one species, P. glaucus (Linnaeus, 1758), was recently split to separate P. canadensis (Rothschild & Jordan, 1906) at species rank (Hagen et al., 1991). Additionally, P. appalachiensis Pavulaan & Wright, 2002, was described as an Appalachian Mountain endemic. The western member of the complex, P. rutulus (Lucas, 1852), has frequently been considered a subspecies of P. glaucus (Scott, 1986; Tyler, Brown & Wilson, 1994), as was P. alexiares (Höpffer, 1866) (Tyler, Brown & …

Twas Facilitates Gene-Scale Trait Genetic Dissection Through Gene Expression, Structural Variations, And Alternative Splicing In Soybean, Delin Li, Qi Wang, Yu Tian, Xiangguang Lyv, Hao Zhang, Huilong Hong, Huawei Gao, Yan-Fei Li, Chaosen Zhao, Jiajun Wang, Ruizhen Wang, Jinliang Yang, Bin Liu, Patrick S. Schnable, James C. Schnable, Ying-Hui Li, Li-Juan Qiu

Department of Agronomy and Horticulture: Faculty Publications

A genome-wide association study (GWAS) identifies trait-associated loci, but identifying the causal genes can be a bottleneck, due in part to slow decay of linkage disequilibrium (LD). A transcriptome-wide association study (TWAS) addresses this issue by identifying gene expression–phenotype associations or integrating gene expression quantitative trait loci with GWAS results. Here, we used self-pollinated soybean (Glycine max [L.] Merr.) as a model to evaluate the application of TWAS to the genetic dissection of traits in plant species with slow LD decay. We generated RNA sequencing data for a soybean diversity panel and identified the genetic expression regulation of 29 …

A Systems Biology Approach To Predict Phenotypes From Genotypes For Plants And Bacteria, Niaz Bahar Chowdhury

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Predicting phenotypes from genotypes is a central challenge in systems biology in understanding how organisms respond to environmental and genetic changes. To address this, genome-scale metabolic models (GSMs) integrated with omics data and machine learning provide a comprehensive framework to connect genotype to phenotype. This dissertation utilizes these approaches in plants and bacterial systems, revealing key metabolic adaptations. In maize, a root-specific GSM reveals metabolic reprogramming under nitrogen stress, offering strategies for improving stress tolerance. Building on this, a multi-organ maize GSM of temperature stress identifies metabolic bottlenecks, providing targets to enhance crop resilience. Similarly, in rice, a grain-specific GSM …
