Utilizing Legumes To Improve Production And Nutritive Value Of Intermountain West Pastures, Jacob T. Briscoe 2018 Utah State University

Utilizing Legumes To Improve Production And Nutritive Value Of Intermountain West Pastures, Jacob T. Briscoe

All Graduate Theses and Dissertations

Pastures in the Intermountain Western United States mainly consist of cool-season grasses which lack production without supplemental nitrogen. Legumes provide nitrogen at reduced cost compared to nitrogen fertilizer. There is a need for proven methods of inter-seeding legumes into existing cool-season grass pastures as well as knowledge of how animals prefer legumes to grasses and how the nutritive value of forages change throughout the growing season. This research provides a resource for effective integration of legumes into pastures of the Intermountain West. Alfalfa, birdsfoot trefoil, and cicer milkvetch were inter-seeded into existing cool-season grass pastures following pretreatments of light tillage ...

The Effect Of Kalanchoe Pinnata On The Cell Migration Of Astrocytomas, Jorge Rosa 2018 University High School

The Effect Of Kalanchoe Pinnata On The Cell Migration Of Astrocytomas, Jorge Rosa

The International Student Science Fair 2018

Astrocytomas, from cell line 1321N1,are cancerous astrocytes. These are a type of glial cell in the brain which is responsible for maintaining synaptic contact and the signaling capacities among neurons. They also represent a fundamental element in controlling blood flow and defining brain micro structure. Due to the fact that this variant is cancerous, a condition commonly described as an abnormal cell cycle and uncontrolled reproduction of cells, they have the ability to metastasize.

In the metastatic process of cancer cells the initial phase is know as tumor invasion. This stage consists mainly of the cells migrating away from ...


How Do Different Levels Of Ph Affect The Growth Of Heritage And Regular Radish Plants?, Kathleen Bradie 2018 Fort Richmond Collegiate

How Do Different Levels Of Ph Affect The Growth Of Heritage And Regular Radish Plants?, Kathleen Bradie

The International Student Science Fair 2018

The purpose of this experiment was to discover how the pH levels in water affect heritage and regular radish mass. I predicted that if the pH levels are near neutral the plants mass will increase. PH solutions of 3, 5, 7, 9, and 11 were added to my regular and heritage plants over the course of several weeks. After using the pH solutions the radishes were pulled and massed to reveal the results. The results showed that the heritage pH 5 and regular pH 7 radishes grew best.


Lipid Transport Required To Make Lipids Of Photosynthetic Membranes, Evan LaBrant, Allison C. Barnes, Rebecca Roston 2018 University of Nebraska–Lincoln

Lipid Transport Required To Make Lipids Of Photosynthetic Membranes, Evan Labrant, Allison C. Barnes, Rebecca Roston

Biochemistry -- Faculty Publications

Photosynthetic membranes provide much of the usable energy for life on earth. To produce photosynthetic membrane lipids, multiple transport steps are required, including fatty acid export from the chloroplast stroma to the endoplasmic reticulum, and lipid transport from the endoplasmic reticulum to the chloroplast envelope membranes. Transport of hydrophobic molecules through aqueous space is energetically unfavorable and must be catalyzed by dedicated enzymes, frequently on specialized membrane structures. Here, we review photosynthetic membrane lipid transport to the chloroplast in the context of photosynthetic membrane lipid synthesis. We independently consider the identity of transported lipids, the proteinaceous transport components, and membrane ...


Designations For Individual Genomes And Chromosomes In Gossypium, Kunbo Wang, Jonathan F. Wendel, Jinping Hua 2018 Chinese Academy of Agricultural Sciences

Designations For Individual Genomes And Chromosomes In Gossypium, Kunbo Wang, Jonathan F. Wendel, Jinping Hua

Ecology, Evolution and Organismal Biology Publications

Gossypium, as the one of the biggest genera, the most diversity, and the highest economic value in field crops, is assuming an increasingly important role in studies on plant taxonomy, polyploidization, phylogeny, cytogenetics, and genomics. Here we update and provide a brief summary of the emerging picture of species relationships and diversification, and a set of the designations for individual genomes and chromosomes in Gossypium. This cytogenetic and genomic nomenclature will facilitate comparative studies worldwide, which range from basic taxonomic exploration to breeding and germplasm introgression.

Field Pea Response To Seeding Rate, Depth, And Inoculant In West-Central Nebraska, Strahinja V. Stepanovic, Charles Burr, Julie A. Peterson, Daran Rudnick, Cody F Creech, Rodrigo Werle

West Central Research and Extension Center, North Platte

Increased market demand and larger adoption of field pea (Pisum sativum L.) in semiarid west-central Nebraska has provided opportunities to replace summer fallow and diversify crop rotations. As a relatively new crop, its response to different seeding practices has not been evaluated in this eco-region. Field pea grain yield response to seeding depth (25, 50, and 75 mm), inoculation with Rhizobium leguminosarum bv. viciae (yes and no rhizobia inoculant), and seeding rates (35, 50, 65, 75, 90, 105, and 120 plants m–2) was investigated in 2015 and 2016 at five sites in Perkins County, NE. There were no differences ...


High Dispersal Ability Is Related To Fast Life-History Strategies, Noelle G. Beckman, James M. Bullock, Roberto Salguero-Gomez 2018 Utah State University

High Dispersal Ability Is Related To Fast Life-History Strategies, Noelle G. Beckman, James M. Bullock, Roberto Salguero-Gomez

Ecology Center Publications

1. Seed dispersal is an essential, yet often overlooked process in plant ecology and evolution, affecting adaptation capacity, population persistence and invasiveness. A species’ ability to disperse is expected to covary with other life-history traits to form dispersal syndromes. Dispersal might be linked to the rate of life history, fecundity or generation time, depending on the relative selection pressures of bethedging, kin competition or maintaining gene flow. However, the linkage between dispersal and plant life-history strategies remains unknown because it is difficult to observe, quantify and manipulate the influence of dispersal over large spatiotemporal scales.

2. We integrate datasets describing ...

A Deep Learning Framework To Discern And Count Microscopic Nematode Eggs, Adedotun Akintayo, Gregory L. Tylka, Asheesh K. Singh, Baskar Ganapathysubramanian, Arti Singh, Soumik Sarkar

Plant Pathology and Microbiology Publications

In order to identify and control the menace of destructive pests via microscopic image-based identification state-of-the art deep learning architecture is demonstrated on the parasitic worm, the soybean cyst nematode (SCN), Heterodera glycines. Soybean yield loss is negatively correlated with the density of SCN eggs that are present in the soil. While there has been progress in automating extraction of egg-filled cysts and eggs from soil samples counting SCN eggs obtained from soil samples using computer vision techniques has proven to be an extremely difficult challenge. Here we show that a deep learning architecture developed for rare object identification in ...

Enhancing the nutritional quality and disease resistance of crops without sacrificing productivity is a key issue for developing varieties that are valuable to farmers and for simultaneously improving food security and sustainability. Expression of the Arabidopsis thaliana species‐specific AtQQS (Qua‐Quine Starch) orphan gene or its interactor, NF‐YC4 (Nuclear Factor Y, subunit C4), has been shown to increase levels of leaf/seed protein without affecting the growth and yield of agronomic species. Here, we demonstrate that overexpression of AtQQS and NF‐YC4 in Arabidopsis and soybean enhances resistance/reduces susceptibility to viruses, bacteria, fungi, aphids, and soybean cyst ...


Nonpolar Residues In The Presumptive Pore‐Lining Helix Of Mechanosensitive Channel Msl10 Influence Channel Behavior And Establish A Nonconducting Function, Grigory Maksaev, Jennette K. Shoots, Simran Ohri, Elizabeth S. Haswell 2018 Washington University in St Louis

Nonpolar Residues In The Presumptive Pore‐Lining Helix Of Mechanosensitive Channel Msl10 Influence Channel Behavior And Establish A Nonconducting Function, Grigory Maksaev, Jennette K. Shoots, Simran Ohri, Elizabeth S. Haswell

Biology Faculty Publications & Presentations

Mechanosensitive (MS) ion channels provide a universal mechanism for sensing and responding to increased membrane tension. MscS‐like (MSL) 10 is a relatively well‐studied MS ion channel from Arabidopsis thaliana that is implicated in cell death signaling. The relationship between the amino acid sequence of MSL10 and its conductance, gating tension, and opening and closing kinetics remains unstudied. Here, we identify several nonpolar residues in the presumptive pore‐lining transmembrane helix of MSL10 (TM6) that contribute to these basic channel properties. F553 and I554 are essential for wild type channel conductance and the stability of the open state. G556 ...

Arabidopsis Thaliana Ei-5: Minor Vein Architecture Adjustment Compensates For Low Vein Density In Support Of Photosynthesis, Jared J. Stewart, Stephanie K. Polutchko, Barbara Demmig-Adams, William W. Adams III 2018 University of Colorado Boulder

Arabidopsis Thaliana Ei-5: Minor Vein Architecture Adjustment Compensates For Low Vein Density In Support Of Photosynthesis, Jared J. Stewart, Stephanie K. Polutchko, Barbara Demmig-Adams, William W. Adams Iii

University Libraries Open Access Fund Supported Publications

An Arabidopsis thaliana accession with naturally low vein density, Eifel-5 (Ei-5), was compared to Columbia-0 (Col-0) with respect to rosette growth, foliar vein architecture, photosynthesis, and transpiration. In addition to having to a lower vein density, Ei-5 grew more slowly, with significantly lower rates of rosette expansion, but had similar capacities for photosynthetic oxygen evolution on a leaf area basis compared to Col-0. The individual foliar minor veins were larger in Ei-5, with a greater number of vascular cells per vein, compared to Col-0. This compensation for low vein density resulted in similar values for the product of vein density ...
