Chloroplast GFP expression in tobacco plants agroinfiltrated with tobacco mosaic virus based vectors
(University of Missouri--Columbia, 2009)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Viruses are submicroscopic infectious particles comprising of nucleic acid and protein which can replicate only within living host cells. TMV is a ... -
Co-ordinated expression of CRTB, At-VTE3, and VTE4 to enhance pro-vitamin A and vitamin E in transgenic soybean
(University of Missouri--Columbia, 2013)Although soybean is an excellent general nutritional source, it is not very rich in particular vitamins. The main goal of this study is to enhance both pro-vitamin A (carotenoids) and vitamin E (tocopherols) content in ... -
Comparative analysis of aquatic insect, amphipod, and isopod community composition along environmental gradients in rheocrene spring systems of Missouri
(University of Missouri--Columbia, 2010)Spring systems in Missouri harbor a unique biota and provide critical initial discharge from subterranean aquifers to streams. However, little research has been conducted on the crenobiology or ecology in these systems. ... -
Comparative analysis of the role of cytokinin in feeding site formation induced by cyst and root-knot nematodes
(University of Missouri--Columbia, 2017)Cyst and root-knot nematodes are obligate plant parasites of global economic importance with a remarkable ability to reprogram root cells into unique feeding sites. Previous studies have suggested a role for cytokinin in ... -
Comparing mosquito communities of various patch-matrix landscape combinations in central Missouri, with implications for developing models to forecast abundances of important mosquito taxa
(University of Missouri--Columbia, 2010)Disease vector population densities, combined with their relationship to landscape characters, will clearly affect the proliferation of arboviruses to humans present in these landscapes. Advanced mapping techniques (e.g., ... -
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)Subterranean termite species in the genus Reticulitermes are ecologically and economically important in the United States. At least six species of the genus Reticulitermes are native from North American forests where they ... -
Comparison of co-granulated fertilziers to equivalent blends of phosphorus, sulfur, and zinc in a corn-soybean rotation
(University of Missouri--ColumbiaUniversity of Missouri--Columbia, 2015)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] High yielding corn and soybean production systems in Missouri have renewed an interest in micronutrient management such as sulfur (S) which is essential ... -
Comparison of mosquito communities collected from differing livestock locations and an examination of phenotypic traits exhibited by four latitudinally separated populations of Aedes albopictus (Skuse)
(University of Missouri--Columbia, 2013)Mosquito presence and fitness play key roles in the spread of zoonotic pathogens affecting human as well as livestock and wild populations of vertebrates. This study examined the (1) differences between mosquito communities ... -
Comparison of three tall fescue-based stocker systems
(University of Missouri--Columbia, 2009)A two-year study was conducted on tall fescue-based pastures to evaluate three approaches to rotationally stocking stocker calves. Within each year, two sets (a spring set and a fall set) of crossbred steers were stratified ... -
Competition and management of volunteer corn (Zea Mays L.) in corn
(University of Missouri--Columbia, 2011)Volunteer corn (Zea mays L.) is the result of corn kernels remaining in the field following harvest and is a competitive weed in a number of subsequent crops. With widespread adoption of glyphosate-resistant (Gly-R) corn, ... -
A comprehensive, systems-biology analysis of the response of soybean root hairs and stripped roots to heat stress
(University of Missouri--Columbia, 2015)Heat stress is likely to be a key factor in the negative impact of climate change on crop production. Heat stress significantly influences the functions of roots, which provide support, water and nutrients to other plant ... -
Conditions modifying the effect of deleterious agents upon the fungi
(University of Missouri--Columbia, 1905)Nageli, Dandeno and True and Oglevee have drawn the conclusion that the presence of insoluble substances in toxic solutions reduces the toxicity of such solutions. Since in the work already done along this line, phanerogams ... -
Consequences of plant water limitation for aphids, their natural enemies, and insect communities
(University of Missouri--Columbia, 2020)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Climate change is causing an increase in drought events around the world. Water limitation affects the quality and quantity of plant resources for ... -
Conservation and divergence of reproductive phasiRNAs in flowering plants
(University of Missouri--Columbia, 2021)Plant small RNAs (sRNAs) are important regulatory elements that fine-tune gene expression and maintain genome integrity by silencing transposons. They have critical roles in most pathways involved in plant growth and ... -
Control of amaranthus species using dicamba as a pre- and post-herbicide in Missouri
(University of Missouri--Columbia, 2013)The auxinic herbicide dicamba has been used traditionally as a selective post emergent (POST) herbicide for control of broadleaf weeds in monocot cropping systems. Dicamba resistance is an emerging technology that will ... -
Control of Bermudagrass (Cynodon dactylon) in Zoysiagrass (Zoysia japonica) turf by using post-emergence herbicides
(University of Missouri--Columbia, 2012)Bermudagrass and zoysiagrass are two commonly used turfgrass on golf course fairways in the southern and transition zone of the United States. Due to its excellent turf performance and superior cold tolerance compared to ... -
Coordinating the overall stomatal response of plants : rapid leaf-to-leaf communication during light stress
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Plants, being sessile organisms, have evolved unique mechanisms enabling them to rapidly react to ever-changing environmental conditions. In nature, ... -
Corn physiology and yield response to hybrid and seeding rate on claypan soils
(University of Missouri--Columbia, 2015)Yield improvements over the past few decades have been attributed to increasing optimum plant population and not the increase of grain produced per plant. A goal in precision agriculture is to identify seeding rates that ... -
Corn tissue nutrient response related to soil health and fertility
(University of Missouri--Columbia, 2021)Nutrient uptake in corn (Zea mays L.) is influenced by many different factors which include properties of soil health. The push for increasing soil health has raised the question of how soil health and fertility measurements ... -
