Dissecting The Regulatory Network Of Sphingolipid Biosynthesis In Plants, Ariadna Gonzalez-Solis
Dissecting The Regulatory Network Of Sphingolipid Biosynthesis In Plants, Ariadna Gonzalez-Solis
Department of Biochemistry: Dissertations, Theses, and Student Research
Sphingolipids are a diverse group of lipids recognized as important components of cellular membranes and regulators of processes during development and in response to environmental stresses. Serine palmitoyltransferase (SPT) catalyzes the first step in sphingolipid biosynthesis and is a primary regulatory point for homeostasis. ORM proteins have been identified as negative regulators of SPT activity, however the mechanistic details of the regulation are only beginning to be understood. In this work, we show that ORM1 and ORM2 are essential for life cycle completion in Arabidopsis thaliana. Furthermore, the study of a structural ORM1 variant provided information about a transmembrane …

Small streams are a high priority for conservation and an important target for biomonitoring. Stream salamanders are a useful indicator for biotic integrity of headwater streams; however, assessing stream salamanders is a challenging endeavor and existing methods can cause habitat disturbance or require expensive equipment. Our goal was to develop an artificial habitat that mimics the natural habitat that salamanders prefer, leading to rapid colonization and that also (1) represents a standardized area and (2) is easy to handle for rapid assessment. After developing a new artificial habitat (the Maloney Salamander Hotel), we tested the device in a variety of …
Critical Period Of Palmer Amaranth Removal And Effects Of Late Season Herbicide Applications On Palmer Amaranth Seed Production, José Henrique Scarparo De Sanctis
Critical Period Of Palmer Amaranth Removal And Effects Of Late Season Herbicide Applications On Palmer Amaranth Seed Production, José Henrique Scarparo De Sanctis
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Palmer amaranth is the most troublesome weed in agronomic crops in United States. Therefore, an integrated weed management approach is necessary to successfully manage this weed. The use of residual pre-emergence (PRE) herbicide applied at planting can delays the is one of the critical time of Palmer amaranth removal (CTPAR) giving farmers more time to prepare the weed control tactics and to preventing an unacceptable yield loss in soybean due to Palmer amaranth competition. Field experiments were conducted in 2018 and 2019 in a grower’s field infested with GR Palmer amaranth near Carleton, Nebraska, to determine the CTPAR in soybean …

Human Immunodeficiency Virus infection and Acquired Immune Deficiency Syndrome (HIV/AIDS) and associated opportunistic infections are still global health concerns. Traditional medicines have been used for managing these infections, with little about their biological activities being known. This study evaluated antimicrobial and anti-HIV-1 Reverse Transcriptase (RT) activities of medicinal plants; Harungana madagascariensis, Sapium ellipticum, Pseudospondias microcarpa, Capparis erythrocarpos, and Plectranthus barbatus; and activities of zinc oxide nanoparticles synthesized from aqueous extracts of H. madagascariensis. Results revealed that aqueous and ethyl acetate extracts of H. madagascariensis, S. ellipticum, P. microcarpa; and ethyl acetate extracts from P. barbatus exhibited minimum inhibitory concentrations ranging …

Tanzania Journal of Science
Leaf parts of vegetable plants grown on irrigated farmlands and are easily accessed by contaminants; pose greater risks of being contaminated with heavy metals. Soil, irrigation water and edible vegetable plants were collected and evaluated for concentrations of heavy metals using Atomic Absorption Spectrophotometry (AAS) and standard laboratory methods. Physicochemical parameters of irrigation water, compared with WHO limits for chloride (326.14 + 7.03 mg/L, 250 mg/L), total hardness (196.0 + 8.72 mg/L, 150 mg/L), chemical oxygen demand (286.4 ±1.35 mg/L; 150 mg/L) and alkalinity (171.0 + 4.36 mg/L, 120 mg/L) were significantly (p ˂ 0.05) higher than the control sites …

Tanzania Journal of Science
This study reports the biogenic synthesis of silver nanoparticles (AgNPs) using aqueous extract obtained from Anacardium occidentale stem bark and evaluation of their antibacterial activities as well as their potential applications as antimicrobial additives for detergent and toothpaste. The biosynthesized AgNPs were analyzed using UV–Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The particles were dark brown in colour with maximum absorbance at wavelength 419 nm. They were mainly spherical in shape with size ranges from 20 to 60 nm. The peaks of FTIR spectrum revealed that their formation was facilitated by protein molecules present in the …

Sensitivity Analysis And Uncertainty Parameter Quantification In A Regression Model: The Case Of Deforestation In Tanzania, Thadei Sagamiko, Nyimvua Shaban, Isambi S. Mbalawata
Tanzania Journal of Science
In this paper a multiple regression model for the economic factors and policy that influence the rate of deforestation in Tanzania is formulated. Sensitivity analysis for parameters of explanatory variables using one-at-a time and direct methods is carried out and the model is fitted by classical least square (LSQ) and Markov Chain Monte Carlo (MCMC) methods. Uncertainty quantification of parameters by adaptive Markov Chain Monte Carlo methods is performed. The coefficient of determination indicates that 87% of deforestation rate is explained by explanatory variables captured in the model. Household poverty rate is found to be the most sensitive factor to …

Selected Under-Exploited Plant Oils In Nigeria: A Correlative Study Of Their Properties, Ikhazuagbe H. Ifijen, Adachukwu N. Nkwor
Tanzania Journal of Science
This study examined the physicochemical properties of seven under-exploited plant oils in Nigeria, namely; Hevea brasiliensis seed oil (HBSO), Prunus dulcis seed oil (PDSO), Afzelia africana aril cap oil (AAACO), Jatropha curcas seed oil (JCSO), Sesamum indicum seed oil (SISO), Canarium schweinfurthii seed oil (CSSO) and Hura crepitans seed oil (HCSO). Characteristics such as colour, percentage yield, specific gravity, freezing/melting point, acid value, free fatty acid, iodine value, and saponification value were investigated. The results showed that they have different colours and are liquid at room temperature. The percentage yield of the extracted oils varied from 34 to 55.39%. The …

Tanzania Journal of Science
This study compared the growth performance of Eucheuma denticulatum, fish abundance and diversity between deep water (using tubular nets) versus shallow water (off-bottom) seaweed farming methods. For each farming method, three plots were set and fish abundance, diversity and seaweed growth rates were measured at intervals of 15 days. Belt transects measuring 10 m x 4 m each, were established on seaweed farms for fish observations. Fish were identified to the lowest possible taxonomic level by underwater census. The results showed that the growth rate of E. denticulatum in deep water farms was slightly higher at an average daily growth …

Small RNAs play a number of vital roles in plants, including viral resistance. A particular class of small RNA that regulates plant defense from pathogens, among other functions, is known as small interfering RNAs (siRNAs). A key player in the biogenesis pathway of siRNAs are RNA-Dependent RNA Polymerases (RDRs). There are six RDR proteins in Arabidopsis thaliana, three of which have well documented roles (RDRs 1, 2 and 6), and three of which have no documented role. Here, we look at the functions of the unstudied RDRs, RDRs 3, 4 and 5, to see whether they affect antiviral resistance.
