Selecting Strawberry Cultivars For Winter Greenhouse Production, Ellen T. Paparozzi, Stacy A. Adams, George E. Meyer, M. Elizabeth Conley, Vicki L. Schlegel, Erin E. Blankenship, Paul E. Read

Department of Agronomy and Horticulture: Faculty Publications

Costs of transportation and food safety concerns have spawned an increase in public support of locally grown vegetables and fruit. With this in mind, a two-phase investigation was planned with the goal of combining low start up costs for sustainable greenhouse production with selection of strawberry cultivars that would provide the greatest number and largest size of berries. Additionally, berries from each cultivar will be analyzed for their beneficial nutraceutical properties to determine if there is a difference among cultivars.

Fine Mapping The Soybean Aphid Resistance Gene Rag1 In Soybean, Ki-Seung Kim, Stephanie Bellendir, Karen A. Hudson, Curtis B. Hill, Glen L. Hartman, D. L. Hyten, Matthew E. Hudson, Brian W. Diers

Department of Agronomy and Horticulture: Faculty Publications

The soybean aphid (Aphis glycines Matsumura) is an important soybean [Glycine max (L.) Merr.] pest in North America. The dominant aphid resistance gene Rag1 was previously mapped from the cultivar ‘Dowling’ to a 12 cM marker interval on soybean chromosome 7 (formerly linkage group M). The development of additional genetic markers mapping closer to Rag1 was needed to accurately position the gene to improve the effectiveness of markerassisted selection (MAS) and to eventually clone it. The objectives of this study were to identify single nucleotide polymorphisms (SNPs) near Rag1 and to position these SNPs relative to Rag1. …

Hyten, Ik-Young Choi, Qijian Song, James E. Specht, Thomas E. Carter Jr., Randy C. Shoemaker, Eun-Young Hwang, Lakshmi K. Matukumalli, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Single nucleotide polymorphisms (SNPs) are the marker of choice for many researchers due to their abundance and the high-throughput methods available for their multiplex analysis. Only recently have SNP markers been available to researchers in soybean [Glycine max (L.) Merr.] with the release of the third version of the consensus genetic linkage map that added 1141 SNP markers to the map. Our objectives were to add 2500 additional SNP markers to the soybean integrated map and select a set of 1536 SNPs to create a universal linkage panel for high-throughput soybean quantitative trait locus (QTL) mapping. The GoldenGate assay …

Efficacy Of Singular And Stacked Brown Midrib 6 And 12 In The Modification Of Lignocellulose And Grain Chemistry, Scott E. Sattler, Deanna L. Funnell-Harris, Jeffrey F. Pedersen 2010 USDA-ARS

Efficacy Of Singular And Stacked Brown Midrib 6 And 12 In The Modification Of Lignocellulose And Grain Chemistry, Scott E. Sattler, Deanna L. Funnell-Harris, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

In sorghum, brown midrib (bmr) 6 and 12 impair the last two steps of monolignol synthesis. bmr genes were introduced into grain sorghum to improve the digestibility of lignocellulosic tissues for grazing or bioenergy uses following grain harvest. Near-isogenic grain sorghum hybrids (AWheatland X RTx430) were developed containing bmr6, bmr12, and the bmr6 bmr12 double mutant (stacked), and their impacts were assessed in a two-year field study. The bmr genes did not significantly impact grain or lignocellulosic tissue yield. Lignocellulosic tissue from bmr6, bmr12, and stacked hybrids had reduced lignin content and increased in …


Heterosis In Sweet Sorghum And Selection Of A New Sweet Sorghum Hybrid For Use In Syrup Production In Appalachia, T. W. Pfeiffer, M. J. Bitzer, J. J. Toy, Jeffrey F. Pedersen 2010 University of Kentucky

Heterosis In Sweet Sorghum And Selection Of A New Sweet Sorghum Hybrid For Use In Syrup Production In Appalachia, T. W. Pfeiffer, M. J. Bitzer, J. J. Toy, Jeffrey F. Pedersen

Department of Agronomy and Horticulture: Faculty Publications

Although heterosis is well established in grain and forage sorghum [Sorghum bicolor (L.) Moench], reports of heterosis in sweet sorghum are limited to results from grain sorghum × sweet sorghum hybrids. Recent development of cytoplasmic male-sterile sweet sorghum lines allows creation of sweet sorghum hybrids for research and industry. Male sterility may also affect allocation of photosynthate to plant parts, creating the potential to increase sugar content in stems by eliminating seed as a sink. The objectives of this study were to compare performance of A3 cytoplasmic male-sterile lines and A3 cytoplasmic male-sterile hybrids to fertile B …


Influences Of Wind And Sandblasting On The Endangered Blowout Penstemon, James Stubbendieck, Cheryl D. Dunn, Heidi L. Hillhouse, L. M. Landholt 2010 University of Nebraska-Lincoln

Influences Of Wind And Sandblasting On The Endangered Blowout Penstemon, James Stubbendieck, Cheryl D. Dunn, Heidi L. Hillhouse, L. M. Landholt

Department of Agronomy and Horticulture: Faculty Publications

Blowout penstemon Penstemon haydenii is a federally endangered species growing only in areas with active wind erosion in sand dunes of the central United States. This early seral species declines as the blowout habitat stabilizes, allowing later seral species to increase. Blowout penstemon populations and plant size declined in the 1990s when precipitation was higher than normal, resulting in reduced sand movement. We conducted a greenhouse experiment to determine whether blowing sand influenced vigor and persistence of blowout penstemon seedlings. Treatments were wind, sandblasting, wind with sandblasting, and a control. The wind treatment was a constant 14 km h–1 …

Fine Mapping Of The Scn Resistance Locus Rhg1-B From Pi 88788, Myungsik Kim, David L. Hyten, Andrew F. Bent, Brian W. Diers

Department of Agronomy and Horticulture: Faculty Publications

Soybean cyst nematode (SCN) (Heterodera glycines Ichinohe) is the most economically damaging soybean [Glycine max (L.) Merr.] pest in the USA and genetic resistance is a key component for its control. Although SCN resistance is quantitative, the rhg1 locus on chromosome 18 (formerly known as Linkage Group G) confers a high level of resistance. The objective of this study was to fi ne-map the rhg1-b allele that is derived from plant introduction (PI) 88788. F2 and F3 plants and F3:4 lines from crosses between SCN resistant and susceptible genotypes were tested with genetic markers to …

High-Throughput Snp Discovery And Assay Development In Common Bean, David L. Hyten, Qijian Song, Edward W. Fickus, Charles V. Quigley, Jong-Sung Lim, Ik-Young Choi, Eun-Young Hwang, Marcial Pastor-Corrales, Perry B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Background: Next generation sequencing has significantly increased the speed at which single nucleotide polymorphisms (SNPs) can be discovered and subsequently used as molecular markers for research. Unfortunately, for species such as common bean (Phaseolus vulgaris L.) which do not have a whole genome sequence available, the use of next generation sequencing for SNP discovery is much more difficult and costly. To this end we developed a method which couples sequences obtained from the Roche 454-FLX system (454) with the Illumina Genome Analyzer (GA) for high-throughput SNP discovery. Results: Using a multi-tier reduced representation library we discovered a total of …

Inoculation With Arbuscular Mycorrhizal Fungi Or Crop Rotation With Mycorrhizal Plants Improves The Growth Of Maize In Limed Acid Sulfate Soil, Hasao Higo, Katsunori Isobe, Dong-Jin Kang, Kazuhiro Ujie, Rhae A. Drijber, Ryuichi Ishii

Department of Agronomy and Horticulture: Faculty Publications

Arbuscular mycorrhizal fungi (AMF) improve the uptake of immobile mineral nutrients such as phosphate, thereby improving plant growth. In acid sulfate soil (ASS), AMF spore density is generally low which impacts root colonization and phosphate uptake. Thus, inoculation may help increase AMF colonization of crops grown in ASS. AMF spore density decreases after cultivation of a non-host crop or bare fallow. In addition, preceding crops affect the growth and yield of subsequent crops. The production of AMF inocula requires AMF-compatible plants. The objective of the present study is to elucidate the effect of preceding crops on the persistence of inoculated …


Fine Mapping Of The Soybean Aphid-Resistance Gene Rag2 In Soybean Pi 200538, Ki-Seung Kim, Curtis B. Hill, Glen L. Hartman, D. L. Hyten, Matthew E. Hudson, Brian W. Diers 2010 University of Illinois

Fine Mapping Of The Soybean Aphid-Resistance Gene Rag2 In Soybean Pi 200538, Ki-Seung Kim, Curtis B. Hill, Glen L. Hartman, D. L. Hyten, Matthew E. Hudson, Brian W. Diers

Department of Agronomy and Horticulture: Faculty Publications

The discovery of biotype diversity of soybean aphid (SA: Aphis glycines Matsumura) in North America emphasizes the necessity to identify new aphid-resistance genes. The soybean [Glycine max (L.) Merr.] plant introduction (PI) 200538 is a promising source of SA resistance because it shows a high level of resistance to a SA biotype that can overcome the SA-resistance gene Rag1 from ‘Dowling’. The SA-resistance gene Rag2 was previously mapped from PI 200538 to a 10-cM marker interval on soybean chromosome 13 [formerly linkage group (LG) F]. The objective of this study was to fine map Rag2. This fine mapping …

2010 Wildflower Of The Year: Wild Ginger, Asarum Canadense, W. John Hayden 2010 University of Richmond

2010 Wildflower Of The Year: Wild Ginger, Asarum Canadense, W. John Hayden

Biology Faculty Publications

Wild ginger is a low herbaceous plant. The stem consists of a branched creeping rhizome at or just below the soil surface. Soft-hairy leaves arise in pairs annually from rhizome branches. Petioles can be up to 20 cm long, elevating the 7—25 mm wide kidney-shaped leaf blades above the forest floor. Small flowers appear in the spring shortly after the leaves have expanded. Typically, one must push the leaves aside in order to glimpse the jug-like flowers. A single flower stalk appears between the paired leaf bases, but it is short and barely lifts the flower above the soil surface. …
