Growth And Productivity Of Irrigated Rice (Oryza Sativa L.) For A Tropical High Altitude Environment In Rwanda, Elie Rene Gasore

Graduate Theses and Dissertations

Yield components, grain yield, biomass and plant N accumulation, and N fertilizer responses of irrigated rice (Oryza sativa, L.) were evaluated for a tropical inland valley environment in the high altitudes in Rwanda. Effects were measured for nitrogen (N) fertilizer rate (0, 60, 90,120,150,180 kg N ha-1), season, growth stage and cultivar of different subspecies and plant types during 2012 dry season (DS) and 2013 wet season (WS) at Cyili Rice Research Farm (1380 m above sea level). Variations in irradiance (17.2± 0.32 MJ m-2 day-1 in DS and 9.4 ± 0.66 MJ m-2 day-1in WS) were linked to seasonal …

Design Of A Nutrient Reclamation System For The Cultivation Of Microalgae For Biofuel Production And Other Industrial Applications, Heather Sandefur

Graduate Theses and Dissertations

Microalgal biomass has been identified as a promising feedstock for a number of industrial applications, including the synthesis of new pharmaceutical and biofuel products. However, there are several economic limitations associated with the scale up of existing algal production processes. Critical economic studies of algae-based industrial processes highlight the high cost of supplying essential nutrients to microalgae cultures. With microalgae cells having relatively high nitrogen contents (4 to 8%), the N fertilizer cost in industrial-scale production is significant. In addition, the disposal of the large volumes of cell residuals that are generated during product extraction stages can pose other economic …

Influence Of Fatty Acids And Their Derivatives On Aphid Resistance In Arabidopsis And Tomato, Jiamei Li

Graduate Theses and Dissertations

Fatty acid desaturases (FADs) are enzymes that act in the chloroplast or the endoplasmic reticulum (ER) to incorporate double bonds into the acyl chains of fatty acids, and recent evidence indicates that at least one of these enzymes, FAD7, also influences plant resistance to aphids. FAD7 is an enzyme in the chloroplast that is found throughout the plant kingdom and that desaturates 16- and 18-carbon fatty acids (FAs) with two double bonds (dienoic acids) to generate FAs with three double bonds (trienoic acids). In tomato (Solanum lycopersicum) and the model plant Arabidopsis thaliana, mutants with impaired FAD7 function are more …

Utilization Of Microsatellite Markers For A Comparative Assessment Of Norton And Cynthiana, And The Linkage Map Construction Of A 'Chambourcin' X 'Cabernet Sauvignon' Population, Mia Elizabeth Mann

Graduate Theses/Dissertations

The first part of this study utilized microsatellites to comparatively assess the cultivars Norton and Cynthiana. Although isozyme and simple sequence repeat (SSR) marker analyses in 1993 and 2009 provided preliminary evidence that Norton and Cynthiana grapes are genetically identical, only five banding patterns and four microsatellite loci were reported. Microsatellites (n=185) spanning 19 linkage groups were used to compare the cultivars for a genome-wide analysis. Capillary electrophoresis results revealed Norton and Cynthiana to be identical at 98.6% of alleles. In the second part of this study, an interspecific hybrid population was generated by crossing V. interspecific hybrid 'Chambourcin' and …

Investigation Of Parasympathetic Effects Of Lavender Essential Oil In Humans, Haakon Robert Nelson, Rachel Ann Burkhart, Daniel Morin, Nicole Grace Weissenfluh, Michael R. Korn

Montview Journal of Research & Scholarship

The purpose of this study will be to investigate the claim that administration of lavender (Lavandula angustifolia) essential oil (topically, orally, and/or respiratorily) produces a relaxative effect in human subjects. This investigation will theoretically be conducted in two stages. Stage one will focus primarily on determining the presence of therapeutic effects and the relative effectiveness of lavender in several application modalities. Stage two will proceed based on findings from stage one. If significant parasympathetic effects are observed in relation to one or more of the lavender oil modalities described above, a more focused investigation will be conducted in stage two …

Unique Nucleic Acid Promoter Formed From Two Or More Promoter Sequences, Indu B. Maiti, Nrisingha Dey

Kentucky Tobacco Research and Development Center Faculty Patents

Non-naturally occurring DNA promoters, include MSGT-PFlt, PFlt-UAS-2X and FSgt-PFlt. The MSGT-PFlt was developed and has expression shown to be equivalent to that of CaMV35S promoter. DNA promoters PFlt-UAS-2X and FSgt-PFlt were developed and tested in transient and transgenic system and found to be stronger than the CaMV35S promoter.

Antifungal Activity Of Essential Oils On Aspergillus Parasiticus Isolated From Peanuts, Mina M. Yooussef, Quyen Pham, Premila Achar, Marikunte Yanjarappa Sreenivasa

Faculty Articles

Aspergillus parasiticus is one of the most common fungi which contaminates peanuts by destroying peanut shells before they are harvested and the fungus produces aflatoxins. The aim of this study was to evaluate the antifungal activities of seventeen essential oils on the growth of the aflatoxigenic form of A. parasiticus in contaminated peanuts from commercial outlets in Georgia. The agar dilution method was used to test the antifungal activity of essential oils against this form of A. parasiticus at various concentrations: 500; 1,000; 1,500; 2,000; 2,500 ppm. Among the seventeen essential oils tested, the antifungal effect of cinnamon, lemongrass, clove …

Aphid Performance Changes With Plant Defense Mediated By Cucumber Mosaic Virus Titer, Xiaobin Shi, Yang Gao, Shuo Yan, Xin Tang, Xuguo Zhou, Deyong Zhang, Yong Liu

Entomology Faculty Publications

Background: Cucumber mosaic virus (CMV) causes appreciable losses in vegetables, ornamentals and agricultural crops. The green peach aphid, Myzus persicae Sulzer (Aphididae) is one of the most efficient vectors for CMV. The transmission ecology of aphid-vectored CMV has been well investigated. However, the detailed description of the dynamic change in the plant-CMV-aphid interaction associated with plant defense and virus epidemics is not well known.

Results: In this report, we investigated the relationship of virus titer with plant defense of salicylic acid (SA) and jasmonic acid (JA) during the different infection time and their interaction with aphids in CMV-infected tobacco plants. …

A Comparative Study Of The Flora And Soils Of Great Duck And Little Duck Islands, Maine, Usa, Luka Negoita, Matthew Dickinson, Glen H. Mittlehauser, N. Rajakaruna

Biological Sciences

Strong environmental gradients and varied land-use practices have generated a mosaic of habitats harboring distinct plant communities on islands on the coast of Maine. Botanical studies of Maine’s islands, however, are generally limited in number and scope. Baseline studies of Maine’s islands are necessary for assessing vegetation dynamics and changes in habitat conditions in relation to environmental impacts imposed by climate change, rising sea levels, invasive species, pests and pathogens, introduced herbivores, and human disturbance. We conducted a survey of the vascular plants and soils of forest, field, and ocean-side communities of Great Duck and Little Duck Islands, ME. These …
