Influence Of P Fertility On Sweetpotato Rooting During Containerized Transplant Production, Lee T. Rouse Jul 2019

Influence Of P Fertility On Sweetpotato Rooting During Containerized Transplant Production, Lee T. Rouse

LSU Master's Theses

A market for edible landscape transplants continues to increase for vegetable production in the home landscape. A method for extending the salability of sweetpotato transplants in retail outlets is needed because containerized transplants can develop spiraling roots and deformed storage roots. Implementing traditional techniques to ameliorate container-bound roots before planting in the landscape is not advisable. Altering P fertility is a non-chemical and non-mechanical method for slowing sweetpotato rooting. Therefore, sweetpotato cuttings were planted in 100% sand-filled containers and fertilized at 0, 5, 10, 15, 20, and 31 mg L-1 using a modified Hoagland solution over a 6-week period. …

Effects Of Silicon And Beneficial Bacteria On Sheath Blight Of Rice And The Microbial Community Of Rice Rhizosphere, Jhonson Leonard Jul 2019

Effects Of Silicon And Beneficial Bacteria On Sheath Blight Of Rice And The Microbial Community Of Rice Rhizosphere, Jhonson Leonard

LSU Master's Theses

Sheath blight (ShB), caused by Rhizoctonia solani Kühn, is an economically important soil-borne disease of rice (Oryza sativa) that can cause up to 50 % yield losses. Application of fungicides is the most effective and commonly used method for managing sheath blight. However, the pathogen can develop new resistant strains upon continuous exposure to a fungicide. Moreover, the use of inorganic fungicides is not eco-friendly. The utilization biological control agents (BCAs) can be a more sustainable and safe means of managing ShB. To develop alternate strategies for ShB management, I am exploring the effect of the silicon (Si) …

Societal Impact Statement: Food and agricultural plants are integral to human well-being. Due to their universal importance, such plants would appear to represent an ideal entryway by which to address plant blindness. However, with limited opportunities for direct contact with agriculture, many people cannot appreciate the flora that feed us every day. We provide examples of informal education initiatives aimed at increasing public awareness and appreciation of food and agricultural plants, made possible through collaborations between botanic gardens, academic institutions, nonprofits, and agricultural research organizations. We hope these examples encourage and inspire organizations to further utilize food and agricultural plants …

Hole Filling In 3d Scans For Digital Anthropometric Applications, Sima Sobhiyeh, Marcelline Dechenaud, Alexander Dunkel, Margarite Laborde, Samantha Kennedy, John Shepherd, Steven Heymsfield, Peter Wolenski

Faculty Publications

Anthropometric measurements have been used to assess an individual's body composition, disease risk, and nutritional status. Three-dimensional (3D) optical devices can rapidly acquire body surface scans in the form of a triangular mesh which can then be used to obtain anthropometric measurements such as body volume, limb lengths, and circumferences; however, the meshes provided by some scanners may include missing data patches known as holes. These need to be repaired in order to obtain correct landmark detection and automatic calculation of anthropometric measurements -especially body volume. In this study, we present ScReAM (Scan Reconstruction for Anthropometric Measurements) which is a …

Effects Of Virus Infection And Volatiles On Aphid Virus Vector Behavior On Sweetpotato, John Lawrence Dryburgh Jul 2019

Effects Of Virus Infection And Volatiles On Aphid Virus Vector Behavior On Sweetpotato, John Lawrence Dryburgh

LSU Doctoral Dissertations

Sweetpotato is affected by a wide variety of viruses worldwide, which can cause yield losses of up to 90%. Many of these viruses are transmitted by aphids in a non-persistent manner. Non-persistent viruses are acquired and transmitted within minutes, and thus conventional control, such as insecticides, are ineffective. Altering aphid movement and feeding behavior may affect the rate of virus transmission. One potential method to alter aphid behavior is volatile organic compounds (VOC), including volatiles emitted by virus infected plants, plant hormones, and commercial control agents. Aphid movement near sweetpotato fields was monitored to determine trends throughout the growing season. …

Maximizing And Modeling Malonyl-Coa Production In Escherichia Coli, Tatiana Thompson Silveira Mello Jun 2019

Maximizing And Modeling Malonyl-Coa Production In Escherichia Coli, Tatiana Thompson Silveira Mello

LSU Master's Theses

In E. coli, fatty acid synthesis is catalyzed by the enzyme acetyl-CoA carboxylase (ACC), which converts acetyl-CoA into malonyl-CoA. Malonyl-CoA is a major building block for numerous of bioproducts. Multiple parameters regulate the homeostatic cellular concentration of malonyl-CoA, keeping it at a very low level. Understanding how these parameters affect the bacterial production of malonyl-CoA is fundamental to maximizing it and its bioproducts. To this end, competing pathways consuming malonyl-CoA can be eliminated, and optimal nutritional and environmental conditions can be provided to the fermentation broth. Most previous studies utilized genetic modifications, expensive consumables, and high-cost quantification methods, making …

The Link Between Purine Metabolism And Production Of Antibiotics In Streptomyces, Smitha Sivapragasam, Anne Grove Jun 2019

The Link Between Purine Metabolism And Production Of Antibiotics In Streptomyces, Smitha Sivapragasam, Anne Grove

Faculty Publications

© 2019 by the authors. Stress and starvation causes bacterial cells to activate the stringent response. This results in down-regulation of energy-requiring processes related to growth, as well as an upregulation of genes associated with survival and stress responses. Guanosine tetra- and pentaphosphates (collectively referred to as (p)ppGpp) are critical for this process. In Gram-positive bacteria, a main function of (p)ppGpp is to limit cellular levels of GTP, one consequence of which is reduced transcription of genes that require GTP as the initiating nucleotide, such as rRNA genes. In Streptomycetes, the stringent response is also linked to complex morphological differentiation …

A Case-Study Approach To Investigate Transmission, Co-Infection, And Clinical Sequelae During Epidemics Of Dengue And Ebola Virus Disease, Jennifer Elizabeth Giovanni May 2019

A Case-Study Approach To Investigate Transmission, Co-Infection, And Clinical Sequelae During Epidemics Of Dengue And Ebola Virus Disease, Jennifer Elizabeth Giovanni

LSU Doctoral Dissertations

From within their ecologic niches, zoonotic viruses emerge from animal reservoirs into the edges and centers of human habitation to exploit opportunities for unabated transmission within immunologically–naïve populations. Our understanding of where, in whom, and how these viruses emerge is under direct challenge, driving the evolution of modern infectious disease epidemiology within a rapidly-connected global community. The studies presented herein are based on analyses of both aggregate and case-level data, which, we argue, provide unique insight into the complexities of transmission, co-infection, and clinical sequelae occurring within, and arising from, epidemics of emerging zoonotic viruses. In Chapter II, we investigate …
