A First Insight Into Population Structure And Linkage Disequilibrium In The U.S. Peanut Minicore Collection, Vikas Belamkar, Michael Gomez Selvaraj, Jamie L. Ayers, Paxton R. Payton, Naveen Puppala, Mark D. Burow

Department of Agronomy and Horticulture: Faculty Publications

Knowledge of genetic diversity, population structure, and degree of linkage disequilibrium (LD) in target association mapping populations is of great importance and is a prerequisite for LD-based mapping. In the present study, 96 genotypes comprising 92 accessions of the US peanut minicore collection, a component line of the tetraploid variety Florunner, diploid progenitors A. duranensis (AA) and A. ipaënsis (BB), and synthetic amphidiploid accession TxAG-6 were investigated with 392 simple sequence repeat (SSR) marker bands amplified using 32 highly-polymorphic SSR primer pairs. Both distance- and model-based (Bayesian) cluster analysis revealed the presence of structured diversity. In general, the wild-species accessions …

Effects Of Cerium Oxide Nanoparticles On Glycine Max Grown In Hydroponics, Alyssa De La Rosa^, Jose Peralta, Jeff Terry, Jorge Gardea-Torresdey*

COURI Symposium Abstracts, Spring 2011

Cerium oxide nanoparticles (NPs) or nanoceria have a high level of UV absorption and antioxidant behavior, making them great candidates for sun screens, beauty products, and in treating cancer and glaucoma. The increased use of these NPs underscores the importance of understanding their environmental fate and toxicity. So far, information about nanoceria toxicity to plants is scarce. The objectives of this study are to determine the effect of CeO2 NPs on soybean (Glycine max) plant growth and monitor their uptake, deposition, and biotransformation. Soybean plants were treated for 14 days in a modified Hoagland solution containing varying concentrations …

Leaf Number Indicates Salt Tolerance Of Young Seedling Families Of European Aspen (Populus Tremula L.) Growing In Different Soils, Lu-Min Vaario, Kim Yrjälä, Matti Rousi, Timo Sipila, Pertti Pulkkinen

Aspen Bibliography

Soil salinity limits plant productivity and quality. We evaluated the response of 12 aspen (Populus tremula) families to salt stress in two different soils irrigated for 4-weeks with 0, 80 or 160 mM saline solution. Easily measurable characteristics such as shoot height, leaf number, dry mass as well as the distribution of sodium (Na+) ions were measured in 5-month-old aspen seedlings raised in controlled greenhouse conditions on two different soils. Growth among families varied significantly, and the interaction between family and soil type was significant. From 2–5 months, leaf number correlated with that of the first month and salin-ity tolerance. …

Genes Identified By Visible Mutant Phenotypes Show Increased Bias Toward One Of Two Subgenomes Of Maize, James C. Schnable, Michael Freeling

Department of Agronomy and Horticulture: Faculty Publications

Not all genes are created equal. Despite being supported by sequence conservation and expression data, knockout homozygotes of many genes show no visible effects, at least under laboratory conditions. We have identified a set of maize (Zea mays L.) genes which have been the subject of a disproportionate share of publications recorded at MaizeGDB. We manually anchored these ‘‘classical’’ maize genes to gene models in the B73 reference genome, and identified syntenic orthologs in other grass genomes. In addition to proofing the most recent version 2 maize gene models, we show that a subset of these genes, those that …

Dose–Sensitivity, Conserved Non-Coding Sequences, And Duplicate Gene Retention Through Multiple Tetraploidies In The Grasses, James C. Schnable, Brent S. Pedersen, Sabarinath Subramaniam, Michael Freeling

Department of Agronomy and Horticulture: Faculty Publications

Whole genome duplications, or tetraploidies, are an important source of increased gene content. Following whole genome duplication, duplicate copies of many genes are lost from the genome. This loss of genes is biased both in the classes of genes deleted and the subgenome from which they are lost. Many or all classes are genes preferentially retained as duplicate copies are engaged in dose sensitive protein–protein interactions, such that deletion of any one duplicate upsets the status quo of subunit concentrations, and presumably lowers fitness as a result. Transcription factors are also preferentially retained following every whole genome duplications studied. This …

Resource management technical reports

This report provides the underpinning information to help improve the long term profitability of wheat cropping. It documents the realistic potential yield of the 18 million hectares of agricultural land in the South West of Western Australia and the gap between this potential and the actual yields, based on shire averages. This report also summarises major land management constraints that limit the yield potential. This information can be used to aid strategic planning at different levels, for example state, shire and, with care, as a starting point for farm planning.

Assessment Of Pathways For The Introduction And Spread Of Mycobacterium Bovis In The United States, Katie Portacci, Jason Lombard, Lauren Abrahamsen, Eric Bush, Charles Fossler, Robert Harris, Kamina Johnson, Ryan S. Miller, Dianna Mitchell, Randy Pritchard, Steven Sweeney, Todd Weaver

Zoonotics and Wildlife Disease: Publications

Bovine tuberculosis (TB) was responsible for more losses among U.S. farm animals in the early 20th century than all other infectious diseases combined. The Cooperative State-Federal Tuberculosis Eradication Program (established in 1917 and administered by APHIS, State animal health agencies, and U.S. livestock producers) has nearly eradicated bovine TB from the nation’s livestock population. However, despite the many accomplishments of the program, bovine TB remains a serious and costly disease of livestock in the United States. In 1992, VS conducted an assessment to identify pathways for the introduction and spread of bovine TB, in order to develop the most effective …

Effects Of Pruning Level And Canopy Management Practices On Berry Maturation Rate And Harvest Parameters Of Syrah Wine Grapes, Jeffery S. Landolt

Master's Theses

Syrah is an important wine grape in California but is potentially difficult to manage in the vineyard due to its excessive vigor.  Vigorous grapevines require more labor for canopy management and tend to create excess shade, decreasing fruit quality.  Winter pruning level, shoot thinning and leaf removal influence the overall density of the canopy and the subsequent degree of shade in the fruit zone.  An experiment was conducted to assess the effects of two pruning levels with three degrees of labor-intensive canopy management techniques on berry maturation rate and harvest berry parameters for two growing seasons.  In 2008, repeated measures …

Invasive Plant Species As Potential Bioenergy Producers And Carbon Contributors, Stephen L. Young, Gayathri Gopalakrishnan, Deepak R. Keshwani

West Central Research and Extension Center, North Platte

Among recent advances in developing cellulosic and noncellulosic biofuel sources, corn, switchgrass, and others (for example, camelina and canola) have risen to the top. In surveying the landscape, a potentially promising new area of bioenergy production exists—invasive plant species. The addition of invasive plant species as a bioenergy source will help to diversify the nation’s energy dependence and help in the reduction of the negative environmental and social impacts from energy crop production. In addition, belowground carbon stores may provide an opportunity to reduce the impacts associated with global climate change.

Sorghum Clear Beer Value Chain, Bernadette C. Chimai

INTSORMIL Presentations

The markets and industrial utilization of agricultural commodities have undergone considerable change in the last few decades.

In Zambia, sorghum was considered a traditional crop with limited industrial uses.

Research and transformations in consumer tastes and preferences have led to the development of new uses for sorghum.

Potential markets for industrial utilization of sorghum have been identified as food processing, beer brewing, feed concentrates and energy production.

One of the success stories in industrial utilization of sorghum has been Eagle, a sorghum based clear beer produced by Zambian breweries.

The study reported in this paper aims to examine the main …

Mapping Acid Groundwater In Western Australia’S Wheatbelt, Karen Holmes, Adam Lillicrap

Resource management technical reports

The extent of the area affected by deep drains in Western Australia (more than 11 000 km of drains installed as of 2002: Australian Bureau of Statistics 2002) and their continuing installation by land managers make understanding the distribution of naturally occurring acid groundwater a priority for land managers working toward sustainable agricultural production in the wheatbelt. This report describes development of a map of the likelihood of acid groundwater occurrence. It is meant to guide state agencies, natural resource management groups, landholders, and community stakeholders on where acid groundwater may occur.

Soil Nitrogen Transformations Under Elevated Atmospheric Co2 And O3 During The Soybean Growing Season, Engil Isadora Pujol Pereira, Haegeun Chung, Kate Scow, Michael J. Sadowsky, Chris Van Kessel

School of Earth, Environmental, & Marine Sciences Faculty Publications

We investigated the influence of elevated CO2 and O3 on soil N cycling within the soybean growing season and across soil environments (i.e., rhizosphere and bulk soil) at the Soybean Free Air Concentration Enrichment (SoyFACE) experiment in Illinois, USA. Elevated O3 decreased soil mineral N likely through a reduction in plant material input and increased denitrification, which was evidenced by the greater abundance of the denitrifier gene nosZ. Elevated CO2 did not alter the parameters evaluated and both elevated CO2 and O3 showed no interactive effects on nitrifier and denitrifier abundance, nor on total and mineral N concentrations. These results …
