Nanotechnology offers new opportunities for the development of novel materials and strategies that improve technology and industry. This applies especially to agriculture, and our previous field studies have indicated that zinc oxide nanoparticles provide promising nano-fertilizer dispersion in sustainable agriculture. However, little is known about the precise ZnO-NP effects on legumes. Herein, 1 mg·L⁻¹ ZnO-NP spray was dispersed on lentil plants to establish the direct NP effects on lentil production, seed nutritional quality, and stress response under field conditions. Although ZnO-NP exposure positively affected yield, thousand-seed weight and the number of pods per plant, there was no statistically significant …

In chronic lymphocytic leukemia (CLL), the B cell receptor (BCR) plays a critical role in disease development and progression, as indicated by the therapeutic efficacy of drugs blocking BCR signaling. However, the mechanism(s) underlying BCR responsiveness are not completely defined. Selective engagement of membrane IgM or IgD on CLL cells, each coexpressed by more than 90% of cases, leads to distinct signaling events. Since both IgM and IgD carry the same antigen-binding domains, the divergent actions of the receptors are attributed to differences in immunoglobulin (Ig) structure or the outcome of signal transduction. We showed that IgM, not IgD, level …

Collection Priorities Of Pasture Genetic Resources In The Paniceae Native To South Africa, F. L. Müller, M. Trytsman, E. L. Masemola, M. I. Kgonothi, N. R. Mkhize, T. J. Tjelele

IGC Proceedings (1977-2023)

There is an urgent need for the prioritization and ex situ conservation of pasture grass species. Many pasture grasses are still in the process of domestication and grasslands in the tropical, subtropical, semi-arid and arid regions of the world are therefore a major source of genetic material for future forage improvement. Within South Africa, it was found that the Paniceae contains several species with high pasture value and that many populations of these species are found in water-limited environments. Therefore, it was proposed that a strategy be developed for the South African National Forage Genebank to prioritize efforts to collect …

IGC Proceedings (1977-2023)

Several studies have evaluated separately forage production, botanical composition, leaf traits and animal performance. However, few of them have focused on defoliation patterns at the level of functional groups (FGs) under different and variable herbage allowance (HA), especially in natural, diverse grasslands. The objective was to evaluate the relationship between HA and leaf traits on defoliation patterns of mature beef cows in the autumn, winter and spring. We evaluated the grazing probability (GP), intensity of defoliation (ID), and leaf traits on 14 species that represent more than 80% of total dry matter of the pasture. The experiment at which we …

Examining Alternative Water Management Strategies To Support Rio Grande Silvery Minnow Conservation Within And Across Years, Timothy E. Walsworth, Phaedra Budy

Watershed Sciences Faculty Publications

Rio Grande Silvery Minnow (RGSM) are currently constrained to only 5% of their historic range, and their persistence is threatened by highly altered and impaired habitat conditions (Bestgen and Platania 1991). These habitat conditions have resulted from reduced spring and summer flows due to natural variability and anthropogenic water development and extraction, which have resulted in substantial geomorphic changes (Swanson et al. 2011). Successful conservation of this endangered species will require determination of how available flows can be managed to provide conditions supporting growth, reproduction, and survival of RGSM within and across a variety of water years. Previous research has …

Characterizing The Amino Acid Activation Center Of The Naturally Editing-Deficient Aminoacyl-Trna Synthetase Phers In Mycoplasma Mobile, Nien-Ching Han, Arundhati Kavoor, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

To ensure correct amino acids are incorporated during protein synthesis, aminoacyl-tRNA synthetases (aaRSs) employ proofreading mechanisms collectively referred to as editing. Although editing is important for viability, editing-deficient aaRSs have been identified in host-dependent organisms. In Mycoplasma mobile, editing-deficient PheRS and LeuRS have been identified. We characterized the amino acid activation site of MmPheRS and identified a previously unknown hyperaccurate mutation, L287F. Additionally, we report that m-Tyr, an oxidation byproduct of Phe which is toxic to editing-deficient cells, is poorly discriminated by MmPheRS activation and is not subjected to editing. Furthermore, expressing MmPheRS and the hyperaccurate variants renders …

Ultrasound 96 Probe Device Protocol For Cancer Cell Treatment, Aisling Field, Brijesh K. Tiwari, James F. Curtin, Julie R M Mondala, Janith Wanigasekara

Articles

Ultrasound is a sound wave with frequencies ranging between 20 kHz and 20 MHz. Ultrasound is able to temporarily and repeatedly open the BBB safely and enhance chemotherapeutic delivery without adverse effects. This novel technique in drug delivery benefits from the powerful ability of ultrasound to produce cavitation activity. Cavitation is the generation and activity of gas-filled bubbles in a medium exposed to ultrasound. As the pressure wave passes through the media, gas bubbles expand at low pressure and contract at high pressure. This leads to oscillation which produces a circulating fluid flow known as microstreaming around the bubble with …

Can Livestock Alone Be The Main Source Of Income From Rangelands In Poor Countries?, Hossein Arzani, Mohammad Jafari, H. Moradii

IGC Proceedings (1977-2023)

In many countries due to the high population of land holders, there is insufficient range area for each land holder to cover all life expenses. In such places, the income of only livestock in rangelands is not enough to cover living expenses of landholders. The ideas in this paper suggest that researchers should create and explore economic models that incorporate the multiple use concept in rangelands and show how multiple uses are compatible with livestock grazing and to sustain the livelihood of rangeland families.

SDSU Beef Day 2022 Summary Publication

Study Description:

Cattle DMI is an essential component of calculating cattle stocking rates, determining nutrient requirements, and evaluating feed efficiency. Cattle DMI and digestion of forages impact enteric greenhouse gas (GHG) emissions; a major public and environmental concern. Increased GHG levels indicate energy loss during the rumen fermentation process. Obtaining data for rangeland cattle DMI and GHG emissions is needed to understand and enhance individual animal performance and reduce negative environmental impacts. We will develop enteric emissions and DMI relationships by conducting three feeding trials using the GreenFeed and SmartFeed Pro (C-Lock Inc. Rapid City, SD). The GreenFeed will measure …

A Robust Technique For Optimal Fitting Of Roll-Over Shapes Of Human Locomotor Systems, Ganesh M. Bapat, Sara A. Myers

Journal Articles

The roll-over shape (ROS) effectively characterizes the lower limb's ability to roll forward during the single-limb support phase of human walking. ROS is modelled as an optimally fitted circular arc to the center of pressure (CoP) data transformed in the shank/leg-based local coordinate system. The commonly used method for optimal fitting of ROS is complex to implement and eliminates inherent individual variability in the ROS parameters during walking. We propose and validate a novel computerized method for optimal fitting of roll-over shapes of the lower limb during walking. Gait data of a healthy individual from Winter's book was used …

Calmodulin Binding To The Dehydrogenase Domain Of Nadph Oxidase 5 Alters Its Oligomeric State, Dustin Smith, Laura Lloyd, Elaine Wei, Paria Radmanesh, Chin-Chuan Wei

SIUE Faculty Research, Scholarship, and Creative Activity

Superoxide generated by NADPH Oxidase 5 (Nox5) is regulated by Ca2+ through the interaction of its self-contained Ca2+ binding domain and dehydrogenase domain (DH). Recently, calmodulin (CaM) has been reported to enhance the Ca2+ sensitivity of Nox5 by binding to the CaM-binding domain sequence (CMBD), in which the interaction between CaM and Nox5 is largely unclear. Here, we used the CMBD peptide and truncated DH constructs, and separately studied their interaction with CaM by fluorescence, calorimetry, and dynamic light scattering. Our results revealed that each half-domain of CaM binds one CMBD peptide with a binding constant near 106 …

Seed retention, and ultimately seed shatter, are extremely important for the efficacy of harvest weed seed control (HWSC) and are likely influenced by various agroecological and environmental factors. Field studies investigated seed-shattering phenology of 22 weed species across three soybean [Glycine max (L.) Merr.]-producing regions in the United States. We further evaluated the potential drivers of seed shatter in terms of weather conditions, growing degree days, and plant biomass. Based on the results, weather conditions had no consistent impact on weed seed shatter. However, there was a positive correlation between individual weed plant biomass and delayed weed seed-shattering rates during …

Department of Agronomy and Horticulture: Faculty Publications

Accurate nitrogen (N) diagnosis early in the growing season across diverse soil, weather, and management conditions is challenging. Strategies using multi-source data are hypothesized to perform significantly better than approaches using crop sensing information alone. The objective of this study was to evaluate, across diverse environments, the potential for integrating genetic (e.g., comparative relative maturity and growing degree units to key developmental growth stages), environmental (e.g., soil and weather), and management (e.g., seeding rate, irrigation, previous crop, and preplant N rate) information with active canopy sensor data for improved corn N nutrition index (NNI) prediction using machine learning methods. Thirteen …

Impact Of Grazing Management On Productivity Of Tropical Grasslands, Moacyr Corsi, Geraldo B. Martha Jr., Domício Do Nascimento Jr., Marco A. A. Balsalobre

IGC Proceedings (1977-2023)

Beef and dairy cattle enterprises from tropical pasture-based systems are notoriously of low productivity. The low soil fertility, the exploitation of native grasslands, the low genetic potential of the animals and the poor management of soil, pasture and animal components are all arguments used to explain these “low-productivity systems”. In fact, research has consistently indicated up to 50% increase in calving rate when animals grazing unfertilized pastures were supplemented with trace-mineralized salt (Table 1) but unfortunately less than 90% of Brazilian farmers use this management strategy (Tosi, 1997). However, a recent survey conducted by São Paulo State government showed that …

Impact Of Grazing Management On The Productivity Of Cold Temperate Grasslands Of Southern Patagonia - A Critical Assessment, A. F. Cibils, M. B. Coughenour

IGC Proceedings (1977-2023)

The contention that productivity of cold temperate grasslands of southern Patagonia have been greatly affected by domestic herbivore grazing in the past is fairly widespread. The consequences of spatiotemporal interactions between grazing and abiotic factors on the overall productivity of such systems, however, are still poorly understood. Predictions of both short- and long-term impacts of grazing management strategies on grassland productivity require a better understanding of these interactions. In this paper we make a critical assessment of the impact of grazing management on long-term sustainability of the grass steppes of southern Patagonia (Argentina). We discuss this issue in the context …

IGC Proceedings (1977-2023)

A six-year study was conducted in a Mediterranean grassland in north-eastern Israel to investigate the effects of cattle grazing management on a perennial legume, Bitumen Trefoil (Bituminaria bituminosa (L.) Stirton). The relationship between grazing pressure and its relative plant cover was studied in the context of inter-annual variation in rainfall. Treatments included manipulations of stocking rates (moderate, heavy and very heavy) and of grazing regimes (continuous vs. seasonal), in a factorial design. The results showed that inter-seasonal rainfall variation was a dominant factor in the expression of plant cover changes of this species. Grazing showed no significant effect on …
