Comparison Of Instrumental Methods For Measuring Seed Hardness Of Food-Grade Soybean, Mioko Tamura, Bo Zhang, Joyce Berger-Doyle, Pengyin Chen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Seed hardness is an important factor in determining soybean suitability for natto production. There is no established methodology for testing seed texture of soybeans. The objective of this study was to develop an efficient method by examining different instruments and seed parameters that could be potentially used for testing soybean seed hardness. Five food-grade soybean genotypes with different seed sizes were used to determine seed hardness and water-absorption capacity. Water absorption capacity was expressed by swell ratios for seed weight, seed dimension, and volume of water changes before and after soaking. Seed hardness test was conducted by a one-bite method …

Evaluation Of Three Tractor-Guidance Methods For Parallel Swathing At Two Field Speeds, Garris Hudson, Robby Shofner, George Wardlow, Donald Johnson

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

This study compared the accuracy (mean error and rms error) and precision (standard deviation of error) of three tractor-guidance methods (foam-marker, light-bar, and assisted-steering systems) at two field speeds (5.6 – and 11.5 km/h) for parallel swathing operations. Eighty-four replications of each combination of guidance method and field speed were conducted between 15 October and 22 December 2006 (504 total field passes). The foam-marker system was found to be significantly less accurate [larger mean error (p < .0001) and had a larger rms error (p < .0001)] than either the light-bar or the assisted-steering system. There was no significant difference in mean error (p = .6718) or rms error (p = .8841) by field speed. There was a significant interaction between guidance method and field speed for both mean error (p = .0009) and rms error (p = .003). Mean and rms errors for the foam-marker and the assisted-steering systems increased at higher field speed, while the mean and rms errors for the light-bar system decreased at higher speed. The assisted-steering system had a significantly lower (p = .0164) standard deviation of error (higher precision) than the foam-marker or the light-bar systems. There was no significant difference in the standard deviation of error by field speed (p = .6258) or by the interaction of guidance method and field speed (p = .2748).

Publishing Ltd Whole-Plant Mineral Partitioning Throughout The Life Cycle In Arabidopsis Thaliana Ecotypes Columbia, Landsberg Erecta, Cape Verde Islands, And The Mutant Line Ysl1ysl3, Brian M. Waters, Michael A. Grusak

Department of Agronomy and Horticulture: Faculty Publications

• Minimal information exists on whole-plant dynamics of mineral flow through Arabidopsis thaliana or on the source tissues responsible for mineral export to developing seeds. Understanding these phenomena in a model plant could help in the development of nutritionally enhanced crop cultivars. • A whole-plant partitioning study, using sequential harvests, was conducted to characterize growth and mineral concentrations and contents of rosettes, cauline leaves, stems, immature fruit, mature fruit hulls, and seeds of three WT lines (Col-0, Ler, and Cvi) and one mutant line (Col-0::ysl1ysl3). • Shoot mineral content increased throughout the life cycle for all minerals, although tissue-specific mineral …

A Soybean Transcript Map: Gene Distribution, Haplotype And Single-Nucleotide Polymorphism Analysis, Ik-Young Choi, D. L. Hyten, Lakshmi K. Matukumalli, Qijian Song, Julian M. Chaky, Charles V. Quigley, Kevin Chase, K. Gordon Lark, Robert S. Reiter, Mun-Sup Yoon, Eun-Young Hwang, Seung-In Yi, Nevin D. Young, Randy C. Shoemaker, Curtis P. Van Tassell, James E. Specht, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

The first genetic transcript map of the soybean genome was created by mapping one SNP in each of 1141 genes in one or more of three recombinant inbred line mapping populations, thus providing a picture of the distribution of genic sequences across the mapped portion of the genome. Singlenucleotide polymorphisms (SNPs) were discovered via the resequencing of sequence-tagged sites (STSs) developed from expressed sequence tag (EST) sequence. From an initial set of 9459 polymerase chain reaction primer sets designed to a diverse set of genes, 4240 STSs were amplified and sequenced in each of six diverse soybean genotypes. In the …

Cell Wall Proteome In The Maize Primary Root Elongation Zone. Ii. Region-Specific Changes In Water Soluble And Lightly Ionically Bound Proteins Under Water Deficit1[W][Oa], Jinming Zhu, Sophie Alvarez, Ellen L. Marsh, Mary E. Lenoble, In-Jeong Cho, Mayandi Sivaguru, Sixue Chen, Henry T. Nguyen, Yajun Wu, Daniel P. Schachtman, Robert E. Sharp

Department of Agronomy and Horticulture: Faculty Publications

Previous work on the adaptation of maize (Zea mays) primary roots to water deficit showed that cell elongation is maintained preferentially toward the apex, and that this response involves modification of cell wall extension properties. To gain a comprehensive understanding of how cell wall protein (CWP) composition changes in association with the differential growth responses to water deficit in different regions of the elongation zone, a proteomics approach was used to examine water soluble and loosely ionically bound CWPs. The results revealed major and predominantly region-specific changes in protein profiles between well-watered and water-stressed roots. In total, 152 …

Map Location Of The Rpp1 Locus That Confers Resistance To Soybean Rust In Soybean, D. L. Hyten, G. L. Hartman, R. L. Nelson, R. D. Frederick, V. C. Concibido, J. M. Narvel, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

Soybean rust (SBR), caused by Phakopsora pachyrhizi, was first discovered in North America in 2004 and has the potential to become a major soybean [Glycine max (L.) Merr.] disease in the USA. Currently, four SBR resistance genes have been identifi ed but not mapped on the soybean genetic linkage map. One of these resistance genes is the Rpp1 gene, which is present in the soybean accession PI 200492. The availability of molecular markers associated with Rpp1 will permit marker-assisted selection and expedite the incorporation of this gene into U.S. cultivars. We compared simple sequence repeat (SSR) markers between …

Barcsoysnp23: A Panel Of 23 Selected Snps For Soybean Cultivar Identification, M. S. Yoon, Q.J. Song, I. Y. Choi, James E. Specht, D. L. Hyten, P. B. Cregan

Department of Agronomy and Horticulture: Faculty Publications

This report describes a set of 23 informative SNPs (BARCSoySNP23) distributed on 19 of the 20 soybean linkage groups that can be used for soybean cultivar identification. Selection of the SNPs to include in this set was made based upon the information provided by each SNP for distinguishing a diverse set of soybean genotypes as well as the linkage map position of each SNP. The genotypes included the ancestors of North American cultivars, modern North American cultivars and a group of Korean cultivars. The procedure used to identify this subset of highly informative SNP markers resulted in a significant increase …

Ethylene Involvement In The Regulation Of The H+-Atpase Csha1 Gene And Of The New Isolated Ferric Reductase Csfro1 And Iron Transporter Csirt1 Genes In Cucumber Plants, Brian M. Waters, Carlos Lucena, Francisco J. Romera, Gena G. Jester, April N. Wynn, Carmen L. Rojas, Esteban Alcántara, Rafael Pérez-Vicente

Department of Agronomy and Horticulture: Faculty Publications

In previous works using ethylene inhibitors and precursors, it has been shown that ethylene participates in the regulation of several Fe-deficiency stress responses by Strategy I plants, such as enhanced ferric reductase activity, rhizosphere acidification, and subapical root hair development. Furthermore, recent evidence suggests that ethylene could regulate the expression of both the ferric reductase and the iron transporter genes of Strategy I plants by affecting the FER (or FER-like) transcription factor. Recently, two H⁺-ATPase genes have been isolated from cucumber roots, CsHA1 and CsHA2. CsHA1 is up-regulated under Fe deficiency while CsHA2 is constitutively expressed. In …

Fertility Restoration Of The Sorghum A3 Male-Sterile Cytoplasm Through A Sporophytic Mechanism Derived From Sudangrass, Hoang V. Tang, Jeffrey F. Pedersen, Christine D. Chase, Daryl R. Pring

Department of Agronomy and Horticulture: Faculty Publications

Fertility restoration of sorghum [Sorghum bicolor (L.) Moench] lines carrying the IS1112C (A3 group) male-sterile cytoplasm has been documented as a two-gene gametophytic mechanism involving complementary action of restoring alleles designated Rf3 and Rf4, as derived from IS1112C. Fertility restoration capability has also been reported from sudangrass (S. bicolor subsp. drummondii) populations. We describe characteristics of a fertility restoration system derived from sudangrass, in which male-sterile individuals were observed at high frequency in backcross and F2-F3 segregating populations. Segregation analyses were consistent with a sporophytic restoration system involving two complementary genes. Pollen iodine staining in fertile …

Array-Based Genotyping And Expression Analysis Of Barley Cv. Maythorpe And Golden Promise, Harkamal Walia, Clyde Wilson, Pascal Condamine, Abdelbagi M. Ismail, Jin Xu, Xinping Cui, Timothy J. Close

Department of Agronomy and Horticulture: Faculty Publications

Background: Golden Promise is a salt-tolerant spring barley closely related to Maythorpe. Salt tolerance in Golden Promise has been attributed to a single mutation at the Ari-e locus (on 5H) resulting from irradiation of Maythorpe. Golden Promise accumulates lower shoot Na⁺ compared to Maythorpe when growing under saline conditions. This study focused on elucidating the genetic basis and mechanisms involved in this difference. Results: The level of polymorphism between the two genotypes was explored using the Barley1 GeneChip for single feature polymorphisms (SFPs) and an oligonucleotide pool assay for single nucleotide polymorphisms (SNPs). Polymorphism analyses revealed three haplotype blocks …

Nutrient Use Efficiency: Measurement And Management, Achim Dobermann

Department of Agronomy and Horticulture: Faculty Publications

Mineral fertilizers have sustained world agriculture and thus global population and wealth growth for more than 100 years (Smil, 2001; Stewart et al., 2005). Their contribution to increasing crop yields has spared millions of hectares of natural ecosystems that otherwise would have been converted to agriculture (Balmford et al., 2005). However, lacking, imbalanced, inappropriate or excessive use of nutrients in agricultural systems remains a concern. Nutrient mining is a major cause for low crop yields in parts of the developing world, particularly Africa. In other situations, nutrients such as nitrogen (N) and phosphorus (P) often move beyond the bounds of …

Long-Term Evaluation Of Liquid Vs. Granular Nitrogen Fertilization On Creeping Bentgrass [Agrostis Stoloniferous L. Var. Palustris Huds.] And Hybrid Bermudagrass [Cynodon Dactylon (L.) Pers. X C. Transvaalensis Burtt-Davy] Performance, Frederick Totten

All Dissertations

Limited turfgrass research comparing the efficiency of foliar to granular fertilizers exists. To expand upon previous research and to determine advantages and disadvantages between dry and liquid fertilizers applied to turf, research was conducted at Clemson University to compare the efficiency of three nitrogen (N) carriers (100% granular, 100% liquid, and 50% granular + 50% liquid) using N rates ranging from 98 to 390 kg ha-1 on growth and performance of creeping bentgrass and ultra-dwarf bermudagrass.

Studies were conducted in 2003 and 2004 to evaluate liquid and/or granular N fertilization on turfgrass quality, clipping yield, and root biomass of `L-93` …

'Adagio': A Slow-Bolting Arugula, Mario R. Morales, Elizabeth Maynard, Jules -- Janick

Department of Horticulture & Landscape Architecture Faculty Publications

Arugula (Eruca sativa Mill., Brassicaceae) is a fast-growing, cool-season crop that flowers under long days and high temperature. Arugula, also known as rocket (English), roquette (French), rucola (Italian), or rughetta (Italian), is a low-growing annual with dull-green, deeply cut leaves. It contains glucosinolates, such as allyl sulfonocyanate, which give this vegetable a distinct spicy, pungent flavor. During the vegetative stage, the leaves of arugula are large and arranged in a rosette. When the plant bolts, it produces a primary stem, which then branches out into secondary and tertiary stems. Stems eventually end up on raceme-type influorescences with small, creamy white …

Frozen Beetle Treats Are Environmentally Friendly, W. John Hayden

Biology Faculty Publications

At my rural household, the most vexatious insect pest has got to be the ubiquitous Japanese beetle. Native to Japan, these pests have infested most of eastern North America, with isolated infestations appearing in some western states. One reason that Japanese beetles are so bad is that they deliver a double-whammy: the larvae (grubs) consume roots and are particularly destructive of turf and pasture grasses while the adults consume leaves and flowers of a wide variety of plants, leaving behind skeletonized versions of the plant parts consumed.

Growing Chinese Cabbage In Western Australia, John Burt, Dennis Phillips, David Gatter

Bulletins 4000 -

Chinese cabbage is a member of the Brassiceae family, which may be called brassicas, crucifers or cole crops. This includes various crops such as broccoli, Brussels sprouts, cauliflower, cabbage, radish, turnips, swedes and weeds such as wild radish.

In general trade, the term Chinese cabbage can loosely be given to both the heading types (Brasssica rapa L. subsp. pekinensis) and to non heading types such as pak-choi (Brassica rapa L. subsp. chinensis). This Bulletin deals with the heading type of Chinese cabbage. The Chinese name is Wong Bok, and this name is often used in Australia.
