New Approaches To Clover Breeding, M. T. Abberton, T. A. Williams, T. P. T. Michaelson-Yeates, A. H. Marshall, C. Jones, E. Sizer-Coverdale, R. P. Collins

IGC Proceedings (1977-2023)

White clover (Trifolium repens L.) and red clover (T. pratense) are the major forage legumes of temperate pastures. Breeding efforts have focused on overcoming the constraints to productivity and reliability in this species and thereby optimising their contribution to mixed swards. In recent years there has been an increased emphasis on livestock production and the efficient utilisation of forage material in the rumen. In this paper we report on a shift in the aims of forage legume breeding at IGER, building on a strong agronomic platform but giving greater consideration to the environmental footprint of our varieties …

Breeding White Clover With Improved Tolerance Of Nitrogen Fertiliser, T. A. Williams, M. T. Abberton, P. Olyott

IGC Proceedings (1977-2023)

White clover (Trifolium repens L.) is often considered a forage legume with a primary use in 'low input/ low output' systems. One facet of this is the perception that the persistency of this species is poor when Nitrogen (N) fertiliser is applied. However, new varieties of white clover are able to play a significant role in highly productive systems (Williams et al., 2000) and show consistent yields over ten years at a range of applied N levels (Williams et al., 2003). Germplasm improvement for nitrogen tolerance has been carried out with the aim of not only allowing white …

Evaluation Of Lucerne Cultivars For Dry Matter And Seed Production In Latvia, S. Rancane, M. Sparnina

IGC Proceedings (1977-2023)

Lucerne is highly productivity and has a high quality. Nevertheless, lucerne growing in Latvia is limited, because of a large area of acid soils (pH_KCl<5.8) as well as low and unstable seed yields (Berzins, 2002). In recent years lucerne has taken a more important place in forage production in Latvia, because it is a fast growing crop and in good years gives 3-4 harvests per season. It is important to determine which cultivars of lucerne are more productive and give good seed yields every year in Latvia (Luksa, 2002).

Genetic Variability In Different Lucerne (Medicago Sativa) Genotypes, V. Mikić, J. Radović, Z. Lugić, D. Lazarević

IGC Proceedings (1977-2023)

One of the basic goals of modern lucerne breeding programmes is creation of new cultivars with a great potential for high quality and stable yields of both forage and hay (Riday & Brummer, 2002). Such cultivars meet increased needs of animal husbandry and must contribute to diverse farming systems (Luki , 2000). Our trial was aimed at determining genetic variability of yield components in 7 lucerne genotypes, as well as at evaluation of their breeding potential as gene donors to new lucerne cultivars

The Genetic Charactaristic Of Salt Tolerance At The Stage Of Seed Germination In Lucerne, H. Zhou, Q. Yang

IGC Proceedings (1977-2023)

Superweak luminescence exists in all animal and plants; it shows important genetic information. We report the relationship between superweak luminescence and genetic characteristics to salt resistant in lucerne (Medicago sativa). The method can quickly and exactly evaluate the salt-resistance of plants.

Molecular Clone Of The Na+/H+ Antiporter Gene Atnhx1 And Study Of Transgenic Salt Tolerant Lucerne, Q. Yang, H. Zhou, Y. N. Tongquan

IGC Proceedings (1977-2023)

Lucerne (Medicago sativa) with its good quality and ease of cultivation occupies an important position in animal feeding. Salinity is a major constraint of crop productivity, because it reduces yield and limits expansion of agriculture. Na⁺ /H⁺ antiporter catalyses the counter transport of Na⁺ and H⁺ across membranes. Vacuolar Na⁺ /H⁺ antiporter plays an important role in developing salt-tolerance of plants. Therefore, we could use the gene involved in this mechanism to modify salt tolerance of lucerne.

Leaves Of High Yielding Perennial Ryegrass Contain Less Aggregated Rubisco Than S23, A. Kingston-Smith, P. W. Wilkins

IGC Proceedings (1977-2023)

Breeding diploid perennial ryegrass for improved dry matter yield under nitrogen-limiting conditions has reduced the nitrogen (N) concentration of the herbage (Wilkins et al., 2003). Reduced N concentration in the ruminant diet is one potential way to reduce losses of N to the environment by reducing the amount of N that animals excrete. The underlying physiological basis of this increased N-use efficiency in ryegrass was investigated.

Genetic Variability Between Adapted Populations Of Annual Ryegrass (Lolium Multiflorum Lam) In Argentina, A. Andrés, B. S. Rosso, J. De Battista, M. Acuña

IGC Proceedings (1977-2023)

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important annual grasses used in Argentina because it adapts better to the intensive animal system of the Humid Pampas than other annual forage grass. Although much research has been done to study its productive potential and management technologies, little work has focused on breeding and selection. There is ample evidence that genetic variability occurs within grass species (Snaydon, 1987; Andrés and Barufaldi, 1997) both in morphology and physiology. As a result the variation of attributes related with yield potential, quality and adaptation to different management systems, is often used …

Molecular Studies To Evaluate Variegation Of Philodendron Var. Birkin - Are Genetic Mutations Responsible For Variegation In Philodendron Birkin?, Muira C. Arndt, Isabelle R. Gile, Shekinah J. Beerman

Research & Creative Achievement Day

Plant tissue culture and molecular genetic techniques were used to analyze the instability of the genome in philodendron var. 'Birkin'. This plant has variegated, white, green, and greenish-red leaves (that have lost their variegation) on the same plant. Did genetic mutations occur in meristematic sectors of variegated leaves that have reverted to green coloration, or is it an epigenetic change?  PCR and sets of RAPD plastid primers were used to determine if the presence or absence of a PCR product correlated with differences in leaf color and variegation (white, green-white, variegated, reddish green or green leaves). A DNA isolation procedure …

Using Natural Condiments To To Manage Diabetes Mellitus, Vignesh Tiruvannamalai '24

IMSAloquium Student Investigation Showcase

Diabetes mellitus is a predominantly chronic disease that results from blood glucose levels that exceed healthy limits. Diabetes is on the rise in modern times, and an estimated 366.000,000 people are expected to have this disease by 2030. The primary way to treat diabetes and prevent complications is to have proper dietary habits and eat nutritious foods. Some condiments are even known to help reduce blood glucose concentrations. Therefore, these condiments (turmeric, psyllium, barnyard millet, cinnamon, fenugreek, and bitter melon) were added to simulated blood at scaled amounts of 50%, 75%, and 100% of their daily recommended maximum intakes. The …

Minimising Bloat Through Development Of White Clover (T. Repens) With High Levels Of Condensed Tannins, M. T. O’Donoghue, C. Spillane, E. Guiney

IGC Proceedings (1977-2023)

White clover constitutes a low percentage of the overall sward content in Irish pastureland despite EU directives limiting the use of nitrogenous fertilizers. This is mainly due to the tendency of large amounts of white clover to cause bloat. Bloat is a potentially fatal build up of proteinaceous foam in the guts of ruminants. Some lesser cultivated legumes such as Lotus species contain condensed tannins (CT) that decrease the incidence of bloated animals. The project’s objective is to reduce the risk of bloat by generating white clover cultivars with high CT content. We are investigating whether expression of the ANTHOCYANIN …

Polyphenolic Phenomena: Transgenic Analysis Of Some Of The Factors That Regulate The Cell-Specific Accumulation Of Condensed Tannins (Proanthocyanidins) In Forage Crops, Mark P. Robbins, G. Allison, D. Bryant, P. Morris

IGC Proceedings (1977-2023)

Condensed tannins biosynthesised within crops are a well-established mechanism for protecting plant protein in the rumen of grazing livestock. Protein protection mediated by these polymeric flavonoid molecules has been characterised in Lotus spp. and offers an interesting contrast to the polyphenol oxidase (PPO) system that confers protein protection in red clover.

Changes In Gene Expression During Acclimation To Cold Temperatures In White Clover (Trifolium Repens L.), M. Lowe, R. P. Collins, M. T. Abberton

IGC Proceedings (1977-2023)

White clover is an important component of many temperate pastures and improved winter hardiness is a major objective of breeding programmes in many countries. Exposure to cold and fluctuations in temperature are components of winter stress and although some studies have investigated the agronomic and physiological mechanisms of cold tolerance, little research has been carried out to identify the genes involved. We are complementing mapping of quantitative trait loci (QTL) responsible for cold tolerance with studies of variation in gene expression between plants growing at different temperatures. In particular we are initially focusing on the process of acclimation by analysing …

Investigations Of The Effects Of Mutations In Inscuteable Mediated Pins-Mud Complex And Par Complex Functions In Drosophila Neuroblast, Ryan Liu

Research & Creative Achievement Day

Drosophila melanogaster central brain neuroblasts asymmetrically segregate proteins along the cell's apical-basal axil. Divisions along abnormal orientations or the complete failure to divide asymmetrically may result in overgrowth phenotypes. Neuroblastoma, one of the deadliest solid tumor diseases with extremely poor survival rate for late stages, is an example of this dysregulation. The protein Inscuteable (Insc) was previously found to bind with the protein Partner of Inscuteable (Pins; mPins or LGN in mammals), a receptor-independent G-protein activator, which is a subunit of the Pins-Gαi complex. The combined complex recruits Dlg to ensure correct spindle attachment on the cortex of the cell, …

Research & Creative Achievement Day

Ducks (Anatidae) can be found across much of the United States and are hosts to a variety of parasites such as nematodes, trematodes or cestodes. This study focused on identifying the species of the parasites found within ducks based on their morphological features. The morphological structures consisted of body shape, internal organs, mouthparts, and length. The ducks used in this study were legally harvested and donated by hunters from areas across the Mississippi River in Buffalo County and Trempealeau County Wisconsin. A total of 108 ducks have been analyzed for parasites. It is important to identify the types of parasites …

2. A primary future challenge is the conversion of this information into useful functional knowledge for the development of molecular breeding technologies and products that address a range of high impact outcome scenarios in forage and turf.
3. High-throughput approaches for spatial and temporal analysis, from genome to phenome, and the respective data integration in a systems biology context will be critical for …

Crown Rust Resistance In Transgenic Italian Ryegrass (L. Multiflorum) Expressing A Rice Chitinase Gene And Crosses With Cytoplasmic Male Sterile Hybrid Ryegrass, W. Takahashi, M. Fujimori, Y. Miura, T. Komatsu, S. Sugita, A. Arakawa, Y. Nishizawa, H. Sato, Y. Mano, T. Hibi, T. Takamizo

IGC Proceedings (1977-2023)

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grasses in the temperate region. In ryegrasses, crown rust (Puccinia coronata) is the most serious foliar fungal disease and brings about a reduction of herbage yield and loss of palatability to grass-eating domestic animals. In this study, we tried to increase tolerance to the pathogen by introducing a rice chitinase gene using particle bombardment.

Genetic And Molecular Characterization Of Temperate And Tropical Forage Maize Inbred Lines, B. Alarcón-Zúñiga, E. Valadez-Moctezuma, T. Cervantes-Martinez, T. Cervantes-Santana, M. Mendoza‐Rodriguez

IGC Proceedings (1977-2023)

Livestock feeding in the Central highland of Mexico is based on harvest, grazing and annual forage conservation, with forage maize being the most important silage crop (Alarcón, 1995). Even though forage maize is extensively bred in Europe, USA and Asia since the 1900’s, this started in Mexico only in the 1960’s, and little is known about genetic diversity in both agronomic and nutritive value traits. Our breeding program goals are to analyze combining ability of biomass and quality predictors and to study the genetic relationship of inbred lines between lowland tropical and temperate races from Mesa Central, by genetic and …

Intercultural Film Literacy Education Against Cultural Mis-Representation: Finnish Visual Art Teachers’ Perspectives, Sergei Glotov

Journal of Media Literacy Education

Cultural misrepresentation simplifies cultures and their minorities, promotes racism, nationalism and eventually weakens democracies by spreading false information through audio-visual media. Intercultural film literacy education combines intercultural education and film literacy and uses a film as a starting point to discuss the cultural context, to analyse cultural representation and to evaluate how the culture is portrayed from a stylistic and formal point of view. The current study builds upon the previous research that linked intercultural education and film literacy to discuss how visual art teachers understand and practice intercultural film literacy education towards critical analyses of cultural representation in audio-visual …

Cautividad: Deconstructing Notions Of Race And Nation In Argentina 1776–1840, Whitney Rue Wagner

Latin American Studies ETDs

This project is an exploration of the construction and contestation of whiteness in Argentina through the lens of women’s captivity in the middle period. This research explores how representations of captive women were used to construct a national identity via gender, race, and ethnicity, exploring some of the foundational work that would lead to the myth of Argentina as a white nation. By focusing on the various roles these captive women played and centering the complex liminal spaces they negotiated this work seeks to challenge elite historical representations of captive women by highlighting their nuanced socio-political role amongst Indigenous, specifically …

No. 08: Young People’S Mobilities, Farming Aspirations And Engagements In Northern Ghana, Siera Vercillo, Bruce Frayne

Migration and Food Security (MiFOOD) Network

Development policies targeting young people and African agriculture tend to focus on their abandonment of the sector and the need to attract new generations to agricultural activities through its commercialization. This paper points to potential gaps in such interventions by investigating the diverse mobilities, aspirations, and engagements of young people in farming, through a qualitative case study in rural northern Ghana. Our study also challenges the prevalent assumption of African farmers’ movements from rural to rural areas, from rural to urban areas, and out of farming altogether, as we found evidence of young people migrating from urban to rural areas. …

Nviz: Unraveling Neural Networks Through Visualization, Kevin Hoffman

Mathematics, Computer Science & Statistics Presentations

The growing utility of artificial intelligence (AI) is attributed to the development of neural networks. These networks are a class of models that make predictions based on previously observed data. While the inferential power of neural networks is great, the ability to explain their results is difficult because the underlying model is automatically generated. The AI community commonly refers to neural networks as black boxes because the patterns they learn from the data are not easily understood. This project aims to improve the visibility of patterns that neural networks identify in data. Through an interactive web application, NVIZ affords the …
