Automated Conserved Non-Coding Sequence (Cns) Discovery Reveals Differences In Gene Content And Promoter Evolution Among Grasses, Gina Marie Turco, James C. Schnable, Brent S. Pedersen, Michael Freeling

Department of Agronomy and Horticulture: Faculty Publications

Conserved non-coding sequences (CNS) are islands of non-coding sequence that, like protein coding exons, show less divergence in sequence between related species than functionless DNA. Several CNSs have been demonstrated experimentally to function as cis-regulatory regions. However, the specific functions of most CNSs remain unknown. Previous searches for CNS in plants have either anchored on exons and only identified nearby sequences or required years of painstaking manual annotation. Here we present an open source tool that can accurately identify CNSs between any two related species with sequenced genomes, including both those immediately adjacent to exons and distal sequences separated by …

Rate Of Shattercane × Sorghum Hybridization In Situ, Jared J. Schmidt, Jeffrey F. Pedersen, Mark L. Bernards, John L. Lindquist

Department of Agronomy and Horticulture: Faculty Publications

Cultivated sorghum [Sorghum bicolor (L.) Moench subsp. bicolor] can interbreed with a feral weedy relative shattercane [S. bicolor nothosubsp. drummondii (Steud.) de Wet ex Davidse]. Traits introduced from cultivated sorghum could contribute to the invasiveness of a shattercane population. An experiment was conducted to determine the potential for pollenmediated gene flow from grain sorghum to shattercane. Shattercane with juicy midrib (dd) was planted in soybean [Glycine max (L.) Merr.] fields during 2 yr in concentric arcs at varying distances from a 0.39 ha sorghum pollen source with dry midrib (DD). The arcs …

Comparative Feedstock Analysis In Setaria Viridis L. As A Model For C4 Bioenergy Grasses And Panicoid Crop Species, Carloalberto Petti, Andrew Shearer, Mizuki Tateno, Mathew J. Ruwaya, Sue E. Nokes, Tom Brutnell, Seth Debolt

Horticulture Faculty Publications

Second generation feedstocks for bioethanol will likely include a sizable proportion of perennial C4 grasses, principally in the Panicoideae clade. The Panicoideae contain agronomically important annual grasses including Zea mays L. (maize), Sorghum bicolor (L.) Moench (sorghum), and Saccharum officinarum L. (sugar cane) as well as promising second generation perennial feedstocks including Miscanthus × giganteus and Panicum virgatum L. (switchgrass). The underlying complexity of these polyploid grass genomes is a major limitation for their direct manipulation and thus driving a need for rapidly cycling comparative model. Setaria viridis (green millet) is a rapid cycling C4 panicoid grass with a relatively …

Preharvest Quarantine Treatments Of Chlorantraniliprole, Clothianidin, And Imidacloprid-Based Insecticides For Control Of Japanese Beetle (Coleoptera: Scarabaeidae) And Other Scarab Larvae In The Root Zone Of Field-Grown Nursery Trees, Jason B. Oliver, Christopher M. Ranger, Michael E. Reding, James J. Moyseenko, Nadeer N. Youssef, Alicia M. Bray

Agricultural and Environmental Sciences Faculty Research

Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), is an important quarantine pest of nurseries. Nursery plant movement from P. japonica-infested regions is regulated by the U.S. Domestic Japanese Beetle Harmonization Plan (DJHP), which classifies states by risk categories. Treatments for category 2 states include preharvest soil surface treatment of nursery plants grown in field soil using Discus SC, Marathon (1G or 60 WP), or Flagship (0.22G or 25 WG). In this study, Discus, Marathon 60 WP, or Flagship 0.22G DJHP standards were compared with labeled rates of non–DJHP-approved insecticides, including neonicotinoids clothianidin (Arena 50WDG), generic imidacloprid (Quali-Pro Imidacloprid 2 F …

Comparing Effects Of Insecticides On Two Green Lacewings Species, Chrysoperla Johnsoni And Chrysoperla Carnea (Neuroptera: Chrysopidae), K. G. Amarasekare, P. W. Shearer

Agricultural and Environmental Sciences Faculty Research

This study compared lethal and sublethal effects of five insecticides, chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin, on adult and second instars of two green lacewing species, Chrysoperla carnea (Stephens) and Chrysoperla johnsoni Henry, Wells and Pupedis (Neuroptera: Chrysopidae) in the laboratory. Formulated pesticides were tested using concentrations equivalent to the high label rate dissolved in 378.5 liters of water. Novaluron and lambda-cyhalothrin were toxic to larvae and no treated larvae survived to the adult stage. Larva to adult survival was reduced in chlorantraniliprole, cyantraniliprole, and spinetoram treatments. Larva to adult developmental time and sex ratio were not different among the …

Groundcover Management System And Nutrient Source Impact Physical Soil Quality Indicators In An Organically Managed Apple Orchard, Neal Mays

Graduate Theses and Dissertations

In March 2006, four groundcover management systems (GMS) and two nutrient sources (NS) were implemented for their ability to alter the soil physical condition of a newly established, organically managed apple (Malus x domestica Borkh.) orchard. Annual applications of municipal green compost (GC), shredded office paper (SP), wood chips (WC), and mow-blow (MB) grass mulch were utilized as GMS, and NS supplied to trees were from composted poultry litter (PL), a commercial organic fertilizer (CF), or an untreated control (NF) in a 4x3 factorial study. An established, conventionally-managed orchard was located adjacent to the organic research orchard on the same …

The Influence Of Organically Managed High Tunnel And Open Field Production Systems On Strawberry (Fragaria X Ananassa) Quality And Yield, Tomato (Solanum Lycopersicum) Yield, And Evaluation Of Plastic Mulch Alternatives, Jeffrey Thomas Martin

Masters Theses

High tunnels extend the production season, and increase fruit quality, yield and crop marketability of high-value crops, but have been underutilized in the Southeast. In this study, organically managed variety trials of two high-value crops, strawberry (Fragaria x ananassa) and tomato (Solanum lycopersicum), were conducted in high tunnel (HT) and open field (OF) production systems to compare yield and quality. Furthermore, specialty crops are commonly grown on black plastic mulch to increase earliness of harvest, fruit quality and yield. However, plastic disposal is time consuming and costly. Degradable mulches reduce removal costs, lessen environmental impacts, and …

Phosphorous And Potassium Fertility Management For Maximizing Tart Cherry Fruit Quality And Productivity On Alkaline Soils, Sean D. Rowley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Suitable orchard land in regions of the Intermountain West is becoming more limited due to urban sprawl. With the loss of suitable farmland, increasing production costs, and the lack of sound fertility information for these regions, fruit growers face challenges to produce high quality fruit for market demand. Current standard management practices are not sufficient to optimize yield and fruit quality in the marginal farm land that is currently be used for fruit production. Fertility management of orchard trees is vital to tree health, yield, and fruit quality.

Three different approaches were used to investigate the effects of Phosphorus (P) …

Physiological Effects Of Low Mowing Heights, Rolling, And Foot Traffic On Creeping Bentgrass Putting Greens, Joseph Ronald Young

Graduate Theses and Dissertations

Golf course superintendents are managing creeping bentgrass (Agrostis stolonifera L.) putting greens throughout the transition zone where temperatures can exceed optimum levels for consecutive days in the summer. The stress of creeping bentgrass associated with these supraoptimal temperatures has been well documented, but the management practices implemented on putting greens to increase green speeds may exacerbate these environmental stresses. To date, the physiological effects of these management practices in combination have not been evaluated for putting green turf. The objective of this dissertation project was to determine the effect of mowing heights, light-weight rolling, and foot traffic on performance and …

Alternative Poa Species As Permanent And Temporary Turfgrasses In The Transition Zone, Samuel Lucas Freshour

Masters Theses

As restrictions on water, fertilizer, and pesticide use increase, along with public pressure, turfgrass practitioners will need ways to meet the challenges of reduced inputs while still maintaining acceptable turf quality. Proper selection of turfgrass species and cultivars that are adapted to the climate, intended use, and level of expectation is the best and first line of defense for reduced input situations. The objective of this study was to evaluate alternative species from the bluegrass (Poa) genus for their performance as both permanent and temporary winter turfgrass species. In 2010 and 2011, 45 different treatments consisting of 37 different bluegrasses …

Histological And Biochemical Changes In Aegle Marmelos Corr. Before And After Acclimatization, Rajesh Pati

Rajesh Pati

Maximum mortality of micropropagated plants occur during acclimatization phase because plantlets undergo rapid and extreme changes in physiological functioning, histological and biochemical changes. In order to investigate the actual reason of this limitation, test samples were collected at different stages of micropropagation of Aegle marmelos Corr. (In vitro stage, acclimation stage). The biochemical result showed that micropropagated plantlets produced significantly low total chlorophyll (0.042 mg/g fresh weight), reducing sugar (3.227%), NR activity (1.353 NO2/h/g fresh weight) and but higher protein (0.048 μg/g) during in vitro phase. The in vitro raised plants showed abnormal histological features like altered leaf mesophyll, absence …

Response Of Nebraska Horseweed (Conyza Canadensis) Populations To Dicamba, Roberto Crespo, Mark L. Bernards, Greg Kruger, Donald Lee, Robert Wilson Jr.

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Dicamba-resistant soybeans are being developed to provide an additional herbicide mechanism-of-action for postemergence weed control in soybean. Numerous broadleaf species, including horseweed, have evolved resistance to glyphosate. It is anticipated that dicamba will be used by farmers as a primary tool to manage these weeds. Studying and understanding variability in horseweed response to dicamba will aid in developing appropriate risk management strategies to extend the utility of the dicamba-resistance technology. Horseweed plants from ten Nebraska populations were treated with one of nine doses of dicamba in greenhouse experiments. At 28 days after treatment (DAT) visual injury estimations were made and …
