Seed Source May Determine Field-Specific Germination And Emergence: The Source By Planting Environment Interaction, Erin K. Espeland, Lora B. Perkins, Matthew E. Horning, Richard C. Johnson

Natural Resource Management Faculty Publications

Farm environmental conditions and management practices can result in within-cultivar differences in seed quality and lead to transgenerational plasticity (farm-specific effects on offspring, or TGP) that affect germination and emergence in transplant fields. We used three perennial bunchgrasses, [green needlegrass (Nassella viridula) ‘Lodorm’, slender wheatgrass (Elymus trachycaulus) ‘Pryor’, and bluebunch wheatgrass (Pseudoregneria spicata) prevariety registered germplasm P-7] to determine if seeds exhibited TGP. We also determined if TGP was affected by the interaction between production farms and planting environments (farm × environment interaction, or context-dependent TGP), using four laboratory temperature regimes to test germination response and four field environments to …

Evaluating The Impact Of Policies On Production Efficiency Of Nigeria's Rice Economy, Samuel Chukwueyem Rapu Jan 2016

Evaluating The Impact Of Policies On Production Efficiency Of Nigeria's Rice Economy, Samuel Chukwueyem Rapu

Walden Dissertations and Doctoral Studies

Nigeria, like all other rice consuming nations, has experienced a surge in domestic demand for rice since 1970. However, local rice production has not been sufficient to meet local demand, leading to this demand continually being filled by imports. The Federal Government of Nigeria has initiated subsidies programs intended to improve Nigerian rice farmers' technical and cost efficiency levels. This quantitative study evaluated the impact of these policies on the technical and cost efficiency levels of paddy rice farm households in Nigeria. Farrell's (1957) efficiency theory and production theory served as the theoretical frameworks. Data were collected from a cross-section …

Potential Impacts Of The Tpp On Agricultural Trade In The Asia-Pacific Region Utilizing A Gravity Model Framework, Chloe Michelle Worley Jan 2016

Potential Impacts Of The Tpp On Agricultural Trade In The Asia-Pacific Region Utilizing A Gravity Model Framework, Chloe Michelle Worley

LSU Master's Theses

This study examines the impacts RTAs have had in the Asia-Pacific region regarding agricultural trade flows in order to make a prediction on how the proposed TPP agreement will affect the region. The estimation was carried out using a Gravity Model framework to observe the trade creation and trade diversion effects of five existing RTAs in the Asia-Pacific region. These agreements include NAFTA, AFTA, MERCOSUR, APEC, and CER. It is expected that RTAs were to have a positive effect for trade creation and a negative trade diversion effect. The gravity model included export flows of agricultural commodities (defined as food …

A Mycobacterium Avium Subsp. Paratuberculosis Predicted Serine Protease Is Associated With Acid Stress And Intraphagosomal Survival, Abirami Kugadas, Elise A. Lamont, John Bannantine, Fernanda Miyagaki Shoyama, Evan Brenner, Harish K. Janagama, Srinand Sreevatsan Jan 2016

A Mycobacterium Avium Subsp. Paratuberculosis Predicted Serine Protease Is Associated With Acid Stress And Intraphagosomal Survival, Abirami Kugadas, Elise A. Lamont, John Bannantine, Fernanda Miyagaki Shoyama, Evan Brenner, Harish K. Janagama, Srinand Sreevatsan

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The ability to maintain intra-cellular pH is crucial for bacteria and other microbes to survive in diverse environments, particularly those that undergo fluctuations in pH. Mechanisms of acid resistance remain poorly understood in mycobacteria. Although, studies investigating acid stress in M. tuberculosis are gaining traction, few center on Mycobacterium avium subsp. paratuberculosis (MAP), the etiological agent of chronic enteritis in ruminants. We identified a MAP acid stress response network involved in macrophage infection. The central node of this network was MAP0403, a predicted serine protease that shared an 86% amino acid identity with MarP in M. tuberculosis. Previous studies confirmed …

Nlpc/P60 Domain-Containing Proteins Of Mycobacterium Avium Subspecies Paratuberculosis That Differentially Bind And Hydrolyze Peptidoglycan, J. P. Bannantine, Cari K. Lingle, Philip R. Adam, Kasra X. Ramyar, William J. Mcwhorter, William D. Picking, Brian V. Geisbrecht Jan 2016

Nlpc/P60 Domain-Containing Proteins Of Mycobacterium Avium Subspecies Paratuberculosis That Differentially Bind And Hydrolyze Peptidoglycan, J. P. Bannantine, Cari K. Lingle, Philip R. Adam, Kasra X. Ramyar, William J. Mcwhorter, William D. Picking, Brian V. Geisbrecht

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

A subset of proteins containing NlpC/P60 domains are bacterial peptidoglycan hydrolases that cleave noncanonical peptide linkages and contribute to cell wall remodeling as well as cell separation during late stages of division. Some of these proteins have been shown to cleave peptidoglycan in Mycobacterium tuberculosis and play a role in Mycobacterium marinum virulence of zebra fish; however, there are still significant knowledge gaps concerning the molecular function of these proteins in Mycobacterium avium subspecies paratuberculosis (MAP). The MAP genome sequence encodes five NlpC/P60 domain-containing proteins. We describe atomic resolution crystal structures of two such MAP proteins, MAP_1272c and MAP_1204. These …
