The Virome Of Peony And The Population Structure Of Its Most Prominent Viruses, Cullen Shaffer
The Virome Of Peony And The Population Structure Of Its Most Prominent Viruses, Cullen Shaffer
Graduate Theses and Dissertations
Peony (Peonia lactiflora, Pall.) is a popular ornamental that has been cultivated for millennia. Due to its popularity, plant material is frequently moved across international borders allowing for the spread of viruses. The virome of several peony plants was investigated and four viruses; namely Amazon lily mild mottle virus (ALiMMV), Cycas necrotic stunt virus (CNSV), Gentian Kobu-sho associated virus (GKaV) and Lychnis mottle virus (LycMoV) were detected for the first time in the Western Hemisphere. Incidence ranged from a few plants for ALiMMV to near universal infection for CNSV. GKaV was found in individuals that were infected with Lemoine’s disease …
Parallel Strategies To Control Bacterial Panicle Blight Of Rice, Laura Ortega
Parallel Strategies To Control Bacterial Panicle Blight Of Rice, Laura Ortega
Graduate Theses and Dissertations
Bacterial Panicle Blight (BPB) of rice is a seed-borne disease caused by the bacterium Burkholderia glumae. This disease has affected rice production worldwide and its effects are likely to become more devastating with the continuous increase in global temperatures especially during the growing season. Field data has shown that the disease has been more prevalent in years when the temperatures have been unusually high especially at night possibly due to the bacterial adaptation to grow at temperatures higher than 40oC. With the continuous rise in global temperatures, it is likely that this disease will be more problematic. The bacterium can …

Taxonomic And Genetic Diversity, And Pathogenicity Of Diaporthe Species Associated With Soybean, Fakhir Eraheem Hameed Al Shuwaili
Taxonomic And Genetic Diversity, And Pathogenicity Of Diaporthe Species Associated With Soybean, Fakhir Eraheem Hameed Al Shuwaili
Graduate Theses and Dissertations
Diaporthe species (anamorph: Phomopsis) are associated with a wide range of plant hosts as plant pathogens, asymptomatic endophytes, and saprobes. One of these hosts is soybean, which is one of the most important crops in U.S. agriculture. Several Diaporthe species cause important diseases on soybean in the U.S., and specifically in Arkansas. The taxonomy, genetic diversity, and pathogenicity of Diaporthe species associated with asymptomatic infection of soybean are rarely studied with accurate molecular tools. Therefore, this dissertation aimed to assess the diversity and boundaries of Diaporthe associated with soybean in Arkansas. Furthermore, pathogenicity and alternative lifestyles were assessed among Diaporthe …
Dissecting The Cellular Control Of Septin Organization In A Global Cereal Killer, Nawaraj Dulal
Dissecting The Cellular Control Of Septin Organization In A Global Cereal Killer, Nawaraj Dulal
Graduate Theses and Dissertations
Rice blast disease, caused by the filamentous fungus Magnaporthe oryzae, destroys sufficient rice each year to feed 60 million people, and is a serious threat to global food security. A wheat-adapted lineage of M. oryzae now poses threat to global wheat production. Rice blast disease is currently controlled using limited fungicides, and the emergence of fungicide resistance within M. oryzae populations is a growing concern. There is a pressing need to identify new classes of fungicides to control the disease, which requires better understanding of the basic biology of the pathogen. To establish disease, M. oryzae forms a specialized dome …
Introducing An Indigenous Non-Toxigenic Aspergillus Flavus Strain Isolated From Iraqi Corn Grains As A Bio-Control Agent To Reduce Aflatoxin Contamination In Corn Grains, Ali Almatakeez
Graduate Theses and Dissertations
Mycotoxin contamination of cereal crops, such as maize and sorghum, is a global concern because of the potential health effects on humans and animals. Although substantial research has been conducting regarding mycotoxin prevention and mitigation, little information is available about the association of mycotoxin-producing fungi with corn and sorghum grain in Iraq. Identifying and refining indigenous atoxigenic strains to reduce mycotoxin contamination of maize and sorghum has the potential to enhance the nutritional value of these grains while reducing economic losses. However, to our knowledge, this tactic has not yet been adopted by agricultural authorities and farmers in Iraq. To …
An Evaluation Of Unmanned Aircraft Systems' Ability To Assess Stripe Rust In Large Wheat Breeding Nursies, Jamison T. Murry
An Evaluation Of Unmanned Aircraft Systems' Ability To Assess Stripe Rust In Large Wheat Breeding Nursies, Jamison T. Murry
Graduate Theses and Dissertations
Stripe Rust (Puccinia striiformis f. sp. tritici) is a foliar disease that significantly impacts global wheat production, and resistant cultivars provide the most efficient method of control. High-throughput phenotyping using unmanned aircraft systems (UAS) offers a potentially more efficient method for field-based phenotyping compared to visual assessment. Here we tested the ability of remote sensing to predict stripe rust severity in a diverse population of 594 soft red winter wheat lines, planted in single-rows, and evaluated them by visually rating stripe rust intensity and remotely using the dark green color index (DGCI), normalized difference vegetation index (NDVI) and blue NDVI. …
An Evaluation Of Biopesticide Combinations On Yield Performance And Disease/Arthropod Control Of Strawberries Grown In High Tunnel Plasticulture Production Systems In Arkansas., Karlee B. Pruitt
Graduate Theses and Dissertations
This two-year study investigated combinations of biopesticides to determine impacts on strawberry fruit marketable fruit yields, and effectiveness in controlling strawberry pests in a high tunnel production system at the University of Arkansas, Division of Agriculture Research and Extension Center in Fayetteville, Arkansas. Two strawberry cultivars Fragaria × ananassa (Duch.), Camino Real and Sweet Sensation were grown in a high tunnel from early-October to mid-May for two consecutive growing seasons, (2017-18 and 2018-19) with six treatment combinations of biopesticides including an untreated (water) control, nutrient spray and selected biological based fungicides and insecticides, arranged into a split-plot randomized block design. …

Mapping Quantitative Trait Loci For Peach (Prunus Persica) Resistance To Xanthomonas Arboricola Pv. Pruni (Xap) And Determining The Diversity And Virulence Of A United States Xap Collection, Maxwell Vonkreuzhof
Graduate Theses and Dissertations
Bacterial spot, caused by the bacterium Xanthomonas arboricola pv. pruni (Xap), is a threat to the peach [Prunus persica (L.) Batsch], Japanese and European plum (P. salicina L. and P. domestica L.), and tart and sweet cherry (P. cerasus L. and P. avium L.) industries. Markers for fruit resistance to bacterial spot have been developed however, markers associated with foliar resistance have yet to be developed. A total of 130 progeny and 13 parents (n=143) were evaluated for foliar and fruit Xap resistance in 2013, 2014, and 2015, and 162 progeny and eight parents (n=170) in 2017 and 2018 as …
