Economic Contribution Of Agriculture And Food To Arkansas' Gross Domestic Product 1997-2019, Leah English, Jennie Popp, Wayne Miller
Economic Contribution Of Agriculture And Food To Arkansas' Gross Domestic Product 1997-2019, Leah English, Jennie Popp, Wayne Miller
AAES Research Reports and Research Bulletins
Agricultural production, processing, and retail industries are major contributors to Arkansas’ GDP. Agriculture contributes to the state economy through direct agricultural production, value-added processing, and agricultural retail activities. The Agriculture and Food Sector, which is comprised of agricultural production, processing, and retail industries, promotes economic strength through various interactions with other industries. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy and thus plays a vital role in maintaining economic stability throughout the state. This report 1) compares the relative size of the Agriculture and Food Sector in Arkansas with …

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 …

With digitization and data sharing initiatives underway over the last 15 years, an important need has been prioritizing specimens to digitize. Because duplicate specimens are shared among herbaria in exchange and gift programs, we investigated the extent to which unique biogeographic data are held in small herbaria vs. these data being redundant with those held by larger institutions. We evaluated the unique specimen contributions that small herbaria make to biogeographic understanding at county, locality, and temporal scales.

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 …

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 …
Selected Under-Exploited Plant Oils In Nigeria: A Correlative Study Of Their Properties, Ikhazuagbe H. Ifijen, Adachukwu N. Nkwor
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 …

Patterning A Leaf By Establishing Polarities, Darren Manuela, Mingli Xu
Patterning A Leaf By Establishing Polarities, Darren Manuela, Mingli Xu
Faculty Publications
Leaves are the major organ for photosynthesis in most land plants, and leaf structure is optimized for the maximum capture of sunlight and gas exchange. Three polarity axes, the adaxial–abaxial axis, the proximal-distal axis, and the medial-lateral axis are established during leaf development to give rise to a flattened lamina with a large area for photosynthesis and blades that are extended on petioles for maximum sunlight. Adaxial cells are elongated, tightly packed cells with many chloroplasts, and their fate is specified by HD-ZIP III and related factors. Abaxial cells are rounder and loosely packed cells and their fate is established …

Inheritability Of Ciprofloxacin-Induced Mitochondrial Mutations From Parental To Offspring Generation Using Quantitative Polymerase Chain Reaction, Rose Mccoy
Honors Program: Senior Projects (Public)
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 …

Identification Of Planktothrix (Cyanobacteria) Blooms And Effects On The Aquatic Macroinvertebrate Community In The Non-Tidal Potomac River, Usa, Joshua Henesy, Jennifer L. Wolny, John E. Mullican, Detbra S. Rosales, Joseph S. Pitula, Joseph W. Love
Virginia Journal of Science
Using transverse cross-sectional transects, a survey of 31 km of the non-tidal Potomac River was conducted from White’s Ferry, Virginia to Brunswick, Maryland, USA, between June and September in 2013 through 2015 to assess a recurring benthic cyanobacteria bloom. Abundant benthic cyanobacteria blooms were detected during the 2014 and 2015 sampling seasons and the primary taxon was identified morphologically and molecularly as Planktothrix cf. isothrix. When present, P. cf. isothrix blooms were concentrated from river center to the Maryland shoreline. This pattern was correlated with significantly greater benthic chlorophyll-a and phycocyanin concentrations. In an apparent response to …
