Deletion of the first exon of calmodulin-lysine N-methyltransferase (CaM KMT, previously C2orf34) has been reported in two multigene deletion syndromes, but additional studies on the gene have not been reported. Here we show that in the cells from 2p21 deletion patients the loss of CaM KMT expression results in accumulation of hypomethylated calmodulin compared to normal controls, suggesting that CaM KMT is essential for calmodulin methylation and there are no compensatory mechanisms for CaM methylation in humans. We have further studied the expression of this gene at the transcript and protein levels. We have identified 2 additional …

Marketing Contracts, Overconfidence, And Timing In The Canadian Wheat Market, Fabio L. Mattos, Stefanie A. Fryza
Marketing Contracts, Overconfidence, And Timing In The Canadian Wheat Market, Fabio L. Mattos, Stefanie A. Fryza
Department of Agronomy and Horticulture: Faculty Publications
This paper investigates factors that impact marketing performance in the Canadian wheat market. Using data provided by the Canadian Wheat Board (CWB) for six crop years, results indicate that producers were not able to profitably use all marketing contracts offered by the CWB, earlier pricing tended to generate better performance, there was a negative relationship between activeness and performance (suggesting overconfidence in marketing skills), and performance was generally worse in volatile crop years. Further analysis reveals some of these findings differ when outperforming and underperforming producers are investigated separately, particularly with respect to activeness and volatility.

School of Information Faculty Publications
Diaphorina citri (Hemiptera: Psyllidae), the Asian citrus psyllid, is the insect vector of Ca. Liberibacter asiaticus, the causal agent of citrus greening disease. Sequencing of the D. citrimetagenome has been initiated to gain better understanding of the biology of this organism and the potential roles of its bacterial endosymbionts. To corroborate candidate endosymbionts previously identified by rDNA amplification, raw reads from the D. citri metagenome sequence were mapped to reference genome sequences. Results of the read mapping provided the most support for Wolbachia and an enteric bacterium most similar to Salmonella. Wolbachia-derived reads were extracted using …

Lawn Fertilizers For Cool Season Turf, Taun Beddes, Kelly Kopp
All Current Publications
Lawns provide a durable and functional surface for many outdoor activities while adding beauty to the landscape. For these reasons, a healthy, green lawn is the goal of many homeowners and landscape managers. Keeping a lawn healthy and green may require many management practices such as mowing, irrigation and aerification. Often, these practices will include fertilizing with supplemental nutrients at various times during the growing season. This promotes optimum turf color, improves re-growth, and increases tolerance to wear, drought, insects and disease. The broad number of fertilizer options available from retailers can make choosing a fertilizer difficult. However, choosing an …

Aggregation Behavior Of The Southern Chinch Bug (Hemiptera: Blissidae), Karla M. Addesso, Heather J. Mcauslane, Ron Cherry
Aggregation Behavior Of The Southern Chinch Bug (Hemiptera: Blissidae), Karla M. Addesso, Heather J. Mcauslane, Ron Cherry
Agricultural and Environmental Sciences Faculty Research
The southern chinch bug, Blissus insularis Barber, forms dense, multigenerational aggregations in St. Augustinegrass lawns leading to grass death from sap feeding. We conducted laboratory bioassays to better understand the signals responsible for the formation and maintenance of southern chinch bug aggregations. In small arena assays, chinch bugs demonstrated a stronger aggregation response over time and aggregated more often on or beneath St. Augustinegrass leaf blades than on or under artificial leaf-like shelters constructed from white or green paper. In Y-tube olfactometer assays, bugs of different age and sex were attracted to volatiles from mixed-sex chinch bug aggregations and showed …
Is Local Food In Your Future?: An Analysis Of The Viability Of The Local Food Movement, Jennifer A. Sliney
Is Local Food In Your Future?: An Analysis Of The Viability Of The Local Food Movement, Jennifer A. Sliney
Pell Scholars and Senior Theses
The Local Food Movement has arisen in recent decades as a proposed solution to problems in the current food distribution system. Proponents of the movement look to solve problems such as unsustainable farming practices, greenhouse gas emissions, and unhealthy communities. Skeptics raise questions as to whether local food is truly capable of accomplishing any of those. The author proposes that as a solution, aspects of the Local Food Movement such as urban agriculture and attempts at community development should be taken more seriously in order to create a better future for the land and people alike.

Composting Manure And Other Organic Materials, Charles S. Wortmann, Charles A. Shapiro
Department of Agronomy and Horticulture: Faculty Publications
The Composting Process
Composting is the aerobic decomposition of manure or other organic materials in the thermophilic temperature range (104-149oF). Composted material is odorless, fine-textured, and low-moisture. It can be bagged and sold for use in gardens or nurseries, or used as fertilizer on cropland with little odor or fly breeding potential. Composting improves the handling characteristics of any organic residue by reducing its volume and weight. Composting can kill pathogens and weed seeds.
Disadvantages of composting organic residues include loss of nitrogen and other nutrients, time for processing, cost for handling equipment, available land for composting, odors, marketing, diversion …

Arabidopsis thaliana seeds without functional SEED MATURATION PROTEIN1 (SMP1), a boiling soluble protein predicted to be of intrinsic disorder, presumed to be a LATE EMBRYOGENESIS ABUNDANT (LEA) family protein based on sequence homology, do not enter secondary dormancy after 3 days at 40 °C. We hypothesized that SMP1 may protect a heat labile protein involved in the promotion of secondary dormancy. Recombinant SMP1 and GmPM28, its soybean (Glycine max), LEA4 homologue, protected the labile GLUCOSE-6-PHOSPHATE DEHYROGENASE enzyme from heat stress, as did a known protectant, Bovine Serum Albumin, whether the LEA protein was in solution or attached to the bottom …

Escape From Preferential Retention Following Repeated Whole Genome Duplications In Plants, James C. Schnable, Xiaowu Wang, J. Chris Pires, Michael Freeling
Department of Agronomy and Horticulture: Faculty Publications
The well supported gene dosage hypothesis predicts that genes encoding proteins engaged in dose–sensitive interactions cannot be reduced back to single copies once all interacting partners are simultaneously duplicated in a whole genome duplication. The genomes of extant flowering plants are the result of many sequential rounds of whole genome duplication, yet the fraction of genomes devoted to encoding complex molecular machines does not increase as fast as expected through multiple rounds of whole genome duplications. Using parallel interspecies genomic comparisons in the grasses and crucifers, we demonstrate that genes retained as duplicates following a whole genome duplication have only …

Optimizing Greenhouse Corn Production: How Can Two-Spotted Spider Mites Be Controlled?, Robert Eddy, Daniel T. Hahn
Purdue Methods for Corn Growth
This publication describes our experiences controlling mites while conducting experiments to optimize greenhouse corn production. Controlled studies were not conducted, but we recommend cultural practices of water spray-offs of leaf undersides and the stripping lower leaves as the crop ages. Also recommended are applications of beneficial insect Phytoseiulus persimilis at very high rates. The rates are an update of our previous publication. Photos of the pest and cultural practices are provided.

Optimizing Greenhouse Corn Production: What Is The Best Pot Size?, Derek Gambrel, Robert Eddy, Daniel T. Hahn
Purdue Methods for Corn Growth
This publication describes studies conducted to determine best pot size for optimizing greenhouse corn production. We suggest a 2.2-gallon container without large drainage holes extending up the side of the pot. This represents an update of our previous recommendation of a smaller pot, after observing instability in row planting configurations. Photos are included of corn in various size pots.
