The Expression Of Rhizomes In Lotus Corniculatus L., P R. Beuselinck

IGC Proceedings (1997-2023)

Broadleaf birdsfoot trefoil (Lotus corniculatus L.) is a popular crosspollinated, perennial legume cultivated for pasture, or hay and silage production. It does not cause bloat and can be managed to reseed to maintain stands, but significant losses occur when stands decline from disease. Wild birdsfoot trefoil with underground rhizomes was discovered in Morocco. This paper describes research to: 1) compare the morphology and anatomy of rhizomes with aerial stems, 2) determine if rhizomes could be successfully transferred to domesticated germplasm, and 3) determine the inheritance of rhizomes. Morphological and anatomical differences between rhizomes and aerial shoots of five accessions …

Geographical Distribution, Allele Frequency, And Inheritance Of Cry1a.105 And Cry2ab2 Resistance In Helicoverpa Zea In The Southeastern Region Of The United States, Wenbo Yu

LSU Doctoral Dissertations

The corn earworm, Helicoverpa zea (Boddie), is a target pest of Bacillus thuringiensis (Bt) maize and cotton in the U.S. Previous studies have reported that this pest has developed field resistance to pyramided Cry1A/Cry2A maize and cotton in certain areas of the southern United States. The objectives of this study were to 1) determine the current status and distribution of the resistance to Cry1A.105 and Cry2Ab2 in H. zea in the southeastern United States; 2) estimate the resistance allele frequencies to the two Bt proteins in H. zea field populations in the region, and 3) assess the inheritance of the …

Investigation Of Mitochondrial Inheritance In The Smut Fungus Sporisorium Reilianum., Hector Eduardo Mendoza

Electronic Theses and Dissertations

An important goal in evolutionary biology is to address the origin of Earth’s immense biodiversity through the evolution of complex sexual reproduction mechanisms in eukaryotes. Inheritance of mitochondria during sexual reproduction has received special attention in recent years, as these organelles cannot be synthesized de novo and must be transmitted from parent to offspring. The importance of these organelles far exceeds its common function as the energy-producing “powerhouse” of the cell, as it has been found to also be involved in fundamental processes like apoptosis, aging and metabolic homeostasis. Thus, appropriate inheritance of mitochondria is essential for growth and development …

Insights Into Barriers And Educational Needs For Farm Succession Programming, Heather Schlesser, Sandra Stuttgen, Liz Binversie, Joy Kirkpatrick

The Journal of Extension

Planning for farm succession is vital to the longevity of the farm business. To understand the challenges with succession planning, the University of Wisconsin - Division of Extension facilitated focus group meetings across the state. These authors classified the information from the focus groups into eight codes, and each code was further subdivided into themes. The codes included Financial, Communication, Control, Change, Fair vs. Equal, Delivery, and Support, Strategies, and Educational Needs. University of Wisconsin Division of Extension Agriculture Educators utilized the information obtained from the focus groups to create a workbook that provides practical assistance when working with families …

Long-Term Gene–Culture Coevolution And The Human Evolutionary Transition, Timothy M. Waring, Zachary T. Wood

School of Economics Faculty Scholarship

It has been suggested that the human species may be undergoing an evolutionary transition in individuality (ETI). But there is disagreement about how to apply the ETI framework to our species, and whether culture is implicated as either cause or consequence. Long-term gene–culture coevolution (GCC) is also poorly understood. Some have argued that culture steers human evolution, while others proposed that genes hold culture on a leash. We review the literature and evidence on long-term GCC in humans and find a set of common themes. First, culture appears to hold greater adaptive potential than genetic inheritance and is probably driving …

An Evaluation Of College Preparedness On Natural Selection Principles Following The Completion Of An Entry-Level Biology Course, Amy Bell

Murray State Theses and Dissertations

Abstract

Evolution education in secondary education has long been a topic of research. The level of knowledge and acceptance of students upon entering college has been studied using various methods; however, no study had provided the perception of preparedness from the student perspective nor had analyzed the individual Natural Selection principles. This study analyzed college freshmen (n=162) in an entry-level BIO 101 course. Participants were given the Conceptual Inventory of Natural Selection Instrument (CINSI) and perception survey questions upon completion of the course. The CINSI data was then analyzed for each of the four Natural Selection principles as well as …

Inheritability Of Ciprofloxacin-Induced Mitochondrial Mutations From Parental To Offspring Generation Using Quantitative Polymerase Chain Reaction, Rose Mccoy

Honors Theses

In all eukaryotes, mitochondria are known as the powerhouse of the cell (Siekevitz, 1957). In plants, however, their mitochondrial genome is especially strange. Plant mitochondrial genomes are extremely large and contain both linear and circular subgenomic DNA fragments. Plant mitochondrial genomes undergo a significant amount of mutations in the form of rearrangements. However, it is not known how often these rearrangements are inherited by the next generation. It is thought that plant cells that are still dividing have higher rates of DNA repair, such as double-strand break repair, to ensure the quality of that plant lineage. As follows, it is …

Patterns Of Inheritance Of Acylsugar Acyl Groups In Selected Interspecific Hybrids Of Genus Nicotiana, Antoaneta B. Mihaylova-Kroumova, Ivan Artiouchine, Victor D. Korenkov, George J. Wagner

Kentucky Tobacco Research and Development Center Faculty Publications

Glandular trichomes on the surface of Solanaceae species produce acyl sugars that are species-, and cultivar-specific. Acyl sugars are known to possess insecticidal, antibiotic, and hormone-like properties, and as such have great potential as a class of naturally occurring pesticides and antibiotics. The objective of this work was to analyze the acyl composition of acyl sugars in the leaf trichome exudate from selected Nicotiana species and to follow the inheritance of acyl content in their hybrids. Trichome exudates were collected, and the acyl profiles of acyl sugars were identified via GC–MS. The variations in acyl group inheritance in the hybrids …

Quantifying The Economic Value Of Evidence-Based Animal Selection On The Inner Mongolian Desert Steppe, Taro Takahashi, Zhiguo Li, Zhongwu Wang, Guodong Han, Karl Behrendt, David R. Kemp

IGC Proceedings (1997-2023)

Inner Mongolian desert steppe in northwestern China suffers from significant grassland degradation, causing a decrease in producers' income as well as negative off-site impacts (Kemp et al., 2013). Recent studies attribute this problem to a sudden increase in the stocking rate over the last half century, and thus development of an alternative farming system to reduce the animal number is urgently needed (Wang et al., 2011). Scientific experiments and modelling analyses have shown the potential of innovative systems that could deliver a "win-win" solution to local producers and environment (Li et al., 2015). However, the uptake of …

Even though pomological traits are important in fruit breeding for quality, antioxidant capacity and the total content of phenolic compounds have also gained importance, together with a rising awareness of their health benefits. As a result, this study was conducted to evaluate the variation and heritability levels of antioxidant capacity and total phenolic compounds, as well as pomological traits in 'Hacıhaliloğlu' × 'Stark Early Orange' and 'Çataloğlu' × `Stark Early Orange' apricot crosscombinations based on phenotypic assessments of fruit samples. The results indicated significant differences among F1 progenies in the samples involved in the study. Broad-sense heritability coefficients ranged from …

Inheritance Of Single Copy Nuclear Genes (Scngs) In Artificial Hybrids Of Hesperocyparis Arizonica X H. Macrocarpa: Potential For Utilization In The Detection Of Hybridization In Natural Populations, Robert P. Adams, Sam T. Johnson, Mark Miller, Charles Low, Andrea E. Schwarzbach

Health & Biomedical Sciences Faculty Publications and Presentations

Analyses were performed on 18 artificial hybrids from a cross of Hesperocyparis arizonica (male parent) x H. macrocarpa (female parent) using 9 single copy nuclear genes (SCNGs). Three SCNG were found to be informative: myb, 4CL and CnAIB2. Gene myb contained 5 variable sites, of which site 89 was homozygous (CC, TT) as was site 261 (GG, AA) and useful for the detection of hybridization. All 18 hybrids were heterozygous (CT and GA) at these 2 sites as predicted in hybrids. 4CL contained 8 variable sites, of which 1 site (591) was homozygous (TT, CC) and all 18 hybrids were …

Variability, Inheritance Of Fiber Length In 4-5 Specific And Backcross Hybrids, Tolerance Of Cotton Hybrids To Bollworm In Depending Of The Level Of Gossypol, Sayfulla Boboyev, Fakhriddin Kushanov, Ikrom Amanturdiev, Gulnoza Akhmedjanova

Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences

In this paper presents data of researches about fiber length in the 4-5 species. The largest number of plants with the indicated analyzed trait in hybrid combinations, obtained with the participation of the Omad variety, appeared with a number of variations in fiber length at 35.0-36.0 mm and above. Investigation of 4-species hybrids of F2 and back cross hybridization allowed some improvement in the average value of trait when compared with F1. Despite the emergence of transgressive plants with fiber length 36.1-37.0 mm and above, the average trait of composite 5 species hybrids F2 remained almost at the level of …

Subcontinental Heat Wave Triggers Terrestrial And Marine, Multi-Taxa Responses, Katinka X. Ruthrof, David D. Breshears, Joseph B. Fontaine, Ray H. Froend, George Matusick, Jatin Kala, Ben P. Miller, Patrick J. Mitchell, Shaun K. Wilson, Mike Van Keulen, Neal J. Enright, Darin J. Law, Thomas Wernberg, Giles E. St. J. Hardy

Research outputs 2014 to 2021

Heat waves have profoundly impacted biota globally over the past decade, especially where their ecological impacts are rapid, diverse, and broad-scale. Although usually considered in isolation for either terrestrial or marine ecosystems, heat waves can straddle ecosystems of both types at subcontinental scales, potentially impacting larger areas and taxonomic breadth than previously envisioned. Using climatic and multi-species demographic data collected in Western Australia, we show that a massive heat wave event straddling terrestrial and maritime ecosystems triggered abrupt, synchronous, and multi-trophic ecological disruptions, including mortality, demographic shifts and altered species distributions. Tree die-off and coral bleaching occurred concurrently in response …

Spatial Sequestration And Oligomer Remodeling During De Novo [Psi+] Formation, Douglas Lyke, Anita L. Manogaran

Biological Sciences Faculty Research and Publications

Prions are misfolded, aggregated, infectious proteins found in a range of organisms from mammals to bacteria. In mammals, prion formation is difficult to study because misfolding and aggregation take place prior to symptom presentation. The study of the yeast prion [PSI⁺], which is the misfolded infectious form of Sup35p, provides a tractable system to monitor prion formation in real time. Recently, we showed that the de novo formation of prion aggregates begins with the appearance of highly mobile cytoplasmic foci, called early foci, which assemble into larger ring or dot structures. We also observed SDS-resistant oligomers during …

Inheritance, Differential Expression, And Candidate Gene Analyses For Avr2 In Phytophthora Sojae, Chelsea S. Ishmael

Electronic Thesis and Dissertation Repository

Phytophthora sojae is an oomycete responsible for seed, root and stem rot of soybean plants. Managing this disease relies on growing soybean cultivars with race-specific resistance (Rps) genes that deliver complete host immunity in the presence of corresponding pathogen avirulence (Avr) effector proteins. The aims of this study were to characterize virulence towards Rps2 among different P. sojae strains, track the inheritance of this trait, and attempt to identify an Avr2 gene. Fifteen P. sojae strains were tested for virulence towards Rps2 and crosses were performed between selected virulent and avirulent strains to follow the inheritance of virulence. …

Fuzzy Unheritance: A Novel Form Of Somatic Cell Inheritance That Regulates Cell Population Heterogeneity, Batoul Abdallah

Wayne State University Dissertations

Multi-level heterogeneity is a characteristic feature of cancer cell populations. However, how a cell population regulates and maintains its cell population heterogeneity is not well understood. Based on conventional theories of genetic inheritance, cell division is precise, where a daughter cell inherits an identical karyotype from its mother cell. Therefore, errors that are generated during cell division occur at low frequencies that take prolonged time periods to accumulate. However, the overwhelming heterogeneity found in unstable cancers is largely inconsistent with current models of genetic inheritance. In order to determine the mechanism of how heterogeneity is regulated, the pattern of inherited …

Characterization Of Cry1f Resistance In Fall Armyworm, Spodoptera Frugiperda (J.E. Smith) Obtained From Puerto Rico And Florida, Vikash Dangal

LSU Master's Theses

The fall armyworm (Spodoptera frugiperda (J. E. Smith)) is a major pest targeted by transgenic corn expressing Bacillus thuringiensis (Bt) proteins in both North and South America. The objective of this study was to characterize the inheritance and fitness costs of the Cry1F resistance in two fall armyworm populations collected from Puerto Rico (RR-PR) and Florida (RR-FL). To determine the inheritance of the resistance, besides RR-PR, RR-FL, and a Cry1F-susceptible population (Bt-SS), 14 other populations were developed by reciprocal crosses, F1 by F1 crosses, backcrosses, and crosses between RR-PR and RR-FL. Diet-incorporated bioassays were conducted to determine the Cry1F susceptibility …

Inheritance Of Cry1f Resistance, Crossresistance And Frequency Of Resistant Alleles In Spodoptera Frugiperda (Lepidoptera: Noctuidae), A. M. Vélez, T. A. Spencer, A. P. Alves, D. Moellenbeck, R. L. Meagher, H. Chirakkal, B. D. Siegfried

Department of Entomology: Faculty Publications

Transgenic maize, Zea maize L., expressing the Cry1F protein from Bacillus thuringiensis has been registered for Spodoptera frugiperda ( J. E. Smith) control since 2003. Unexpected damage to Cry1F maize was reported in 2006 in Puerto Rico and Cry1F resistance in S. frugiperda was documented. The inheritance of Cry1F resistance was characterized in a S. frugiperda resistant strain originating from Puerto Rico, which displayed >289-fold resistance to purified Cry1F. Concentration–response bioassays of reciprocal crosses of resistant and susceptible parental populations indicated that resistance is recessive and autosomal. Bioassays of the backcross of the F1 generation crossed with the resistant parental …

A Maternally Inherited Autosomal Point In Human Phospholipase C Zeta Leads To Male Infertility, J. Kashir, M. Konstandtinidis, C. Jones, B. Lemmon, H. Lee Chang, R. Hamer, B. Heindryckx, C.M. Deane, P. Desutter, Rafael Fissore, J. Parrington, D. Wells, K. Coward

Rafael Fissore

BACKGROUND Male factor and idiopathic infertility contribute significantly to global infertility, with abnormal testicular gene expression considered to be a major cause. Certain types of male infertility are caused by failure of the sperm to activate the oocyte, a process normally regulated by calcium oscillations, thought to be induced by a sperm-specific phospholipase C, PLCzeta (PLCζ). Previously, we identified a point mutation in an infertile male resulting in the substitution of histidine for proline at position 398 of the protein sequence (PLCζ(H398P)), leading to abnormal PLCζ function and infertility. METHODS AND RESULTS Here, using a combination of direct-sequencing and mini-sequencing …

On-Plant Survival And Inheritance Of Resistance To Cry1ab Toxin From Bacillus Thuringiensis In A Field-Derived Strain Of European Corn Borer, Ostrinia Nubilalis, Andre L. B. Crespo, Terence A. Spencer, Analiza P. Alves, Richard L. Hellmich, Erin E. Blankenship, Leonardo C. Magalhães, Blair D. Siegfried

Department of Entomology: Faculty Publications

BACKGROUND: The high dose plus refuge is one of the major components of the resistance management plan mandated for transgenic corn expressing Cry toxins from Bacillus thuringiensis Berliner (Bt) that targets the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). This strategy was based on assumptions such as functional recessive inheritance, which has not been previously tested for O. nubilalis. The authors used a field-derived resistant strain of O. nubilalis to define the nature of resistance to Cry1Ab toxin by examining the inheritance and on-plant survival of susceptible and resistant insects and their F1 progeny.

RESULTS: The …

Resistance To Bacillus Thuringiensis In Sugarcane Borer, Diatraea Saccharalis (F.), Xiaoyi Wu

LSU Doctoral Dissertations

The sugarcane borer, Diatraea saccharalis (F.), is a dominant corn stack boring pest and a major target of Bacillus thuringiensis (Bt)-corn in many areas of the mid-southern region of the United States. A Cry1Ab-resistant strain of D. saccharalis, capable of survival on commercial Bt corn plants, was established using an F2 screening procedure. Larval survival of Cry1Ab-resistant, -susceptible, and -heterozygous genotypes was evaluated on five non-Bt and seven Bt field corn hybrids at two plant stages. During the vegetative stages, all seven Bt corn hybrids were highly efficacious against the three genotypes, while 8-18% of the heterozygous genotype survived on …

Department of Entomology: Faculty Publications

Laboratory selection with Cry1Ab, the predominant Bacillus thuringiensis (Bt) toxin in transgenic corn, Zea mays L., produced >1000-fold resistance in two laboratory strains of European corn borer, Ostrinia nubilalis (Hubner). We tested the offspring of various crosses to determine the mode of inheritance of resistance to Cry1Ab. Patterns of inheritance of resistance were similar in the two resistant strains. The progeny of reciprocal F₁ crosses (resistant male x susceptible female and vice versa) responded alike in bioassays, indicating autosomal inheritance. The median lethal concentrations (LC₅₀ values) of F₁ were intermediate between the resistant and susceptible parents, indicating …

Inheritance Of Methyl-Parathion Resistance In Nebraska Western Corn Rootworm Populations (Coleoptera: Chrysomelidae), Srivinas Parimi, Michael E. Scharf, Lance J. Meinke, Laurence D. Chandler, Blair D. Siegfried
