The semiaquatic heteroptera (Gerromorpha) of Thailand : faunistics, biogeography and phylogeography
(University of Missouri--Columbia, 2008)
Semiaquatic heteropterans (Gerromorpha) were collected from mountain streams and waterfalls and lowland ponds adjacent to the mountains were collected from 2002 to 2006. One hundred fifty-eight species representing 31 ...
Soybean emergence, growth, and development following corn stover removal
(University of Missouri--Columbia, 2012)
The Energy Independence and Security Act of 2007 mandates the use of 21 billion gallons of biofuel from cellulose or other advanced forms by the year 2022. Corn stover is an attractive choice for cellulosic ethanol production ...
Viability, vigor, and field performance of a low phytic acid, high phytase activity soybean line, CAPPA
(University of Missouri--Columbia, 2009)
Plants store inorganic phosphate (Pi) in seeds as phytic acid (PA). Phytic acid chelates essential macro and micronutrients in developing seeds forming phytate, which is nutritionally unavailable to monogastric livestock. ...
Soybean seed components as affected by nodal position, environmental conditions, and irrigation
(University of Missouri--Columbia, 2005)
Soybeans (Glycine max [L.] Merr.) are a major source of vegetable protein and edible oil. The nutritional quality of these seed components depends upon the relative abundance of specific proteins and fatty acids. Additionally, ...
Herbicide resistant weeds in Missouri : sources and solutions
(University of Missouri--Columbia, 2019)
Herbicide resistant weeds continue to invade new territories each year. Two studies were designed to identify both the spread and the current status of herbicide resistant weeds in Missouri. In 2016 and 2017, 98 separate ...
Modification of fatty acid composition in soybean seeds to improve soybean oil quality and functionality
(University of Missouri--Columbia, 2011)
The purpose of this project is to modify the fatty acid composition in soybean seeds to improve soybean oil quality and functionality. By sequencing the FAD2-1A and FAD2-1B genes in 24 plant introductions, we identified ...
A digestive phospholipase a2 in Midguts of worker honey bees, Apis mellifera : significance in lipid nutrition and health
(University of Missouri--Columbia, 2018)
functions, such as digestion, immune signaling, development and reproduction. However, other than the venom PLA2s, characterization of their physiological functions has not been reported in Hymenoptera, particularly in honey bees (Apis mellifera). Among many...
Function of abscisic acid in maintenance of maize primary root growth under water deficit
(University of Missouri--Columbia, 2006)
Previous studies suggested that ABA accumulation is required to maintain maize primary root elongation under water deficit and that one of the functions of ABA is to restrict ethylene evolution. These studies were conducted ...
Innate immunity in Arabidopsis : molecular mechanisms of HOPA1 and AVRRS4 - specific disease resistance signaling pathways
(University of Missouri--Columbia, 2009)
Plants have evolved several layers of predetermined defenses, collectively called the innate immune system. Because of its effectiveness effector-triggered immunity (ETI) is a highly valuable agronomic trait. However, ETI ...
Switchgrass responses to manganese availability
(University of Missouri--Columbia, 2019)
Manganese (Mn) is an essential micronutrient and has a broad range of functions for all plant growth and reproduction. It plays a crucial role in NAD-ME C4 photosynthesis, including as a constituent of the water splitting ...
Influence of herbicides application on weed and tall fescue management and grazing distribution in Missouri pastures
(University of Missouri--Columbia, 2012)
One weed that is of concern in Missouri pastures that can be detrimental is Northern dewberry (Rubus flagellaris Willd.). This weed can be detrimental due its production of spines which can injure grazing animals and also ...
Interactions between cover crops, herbicides and weeds in soybean production systems
(University of Missouri--Columbia, 2018)
The use of cover crops in soybean production systems has increased in recent decades. There are many questions surrounding cover crops, specifically their benefits to crop production and how to best manage them. One ...
Nested association mapping and accuracy of predicting genomic breeding value for agronomic and seed composition traits in three interspecific soybean populations
(University of Missouri--Columbia, 2019)
Given the narrow genetic base of soybean, discovering useful traits in exotic germplasm could increase the diversity in the current elite gene pool. However, it is essential to characterize beneficial alleles from the wild ...
Examination of host genetic determinants of the hypersensitive response in Nicotiana edwardsonii to CaMV and TMV
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The hypersensitive response (HR) is an indicator of genetic resistance when screening for disease resistance to viral pathogens. Genetic resistance ...
Predator diversity impacts herbivore abundance and behavior with cascading effects on the prevalence of a vector-borne plant pathogen
(University of Missouri--Columbia, 2013)
There is growing concern about the loss of biodiversity; particularly of organisms at higher trophic levels, such as predators, which face a disproportionately higher risk of extinction. As predator diversity declines there ...
Molecular characterization of soybean squalene synthases (GmSQSs) and genetic engineering for enhanced phytosterols in Arabidopsis seeds
(University of Missouri--Columbia, 2009)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Squalene synthase (SQS), which converts fanesyl diphosphate (FPP) to squalene, represents a crucial branch point of the isoprenoid pathway and is ...
Efficacy of oriental mustard (Brassica juncea L. Czern.) seed meal for weed and disease control in turf
(University of Missouri--Columbia, 2009)
Pest management in turf involves the use of fumigants such as methyl bromide, as well as selective pesticides. However, the loss of methyl bromide and development of disease resistance to fungicides suggests that more ...
Environmental and human impacts on off-target movement of dicamba
(University of Missouri--Columbia, 2020)
Widespread use of dicamba on tolerant soybeans (Glycine max L.) since 2017 has resulted in reports of off-target movement. Although symptomology is quite striking, the relationship of sensitive soybean damage to crop yield is unclear. Field studies...
Characterizing hormesis and the in vitro effects of sub-lethal fungicide exposure in sclerotinia homoeocarpa
(University of Missouri--Columbia, 2018)
Dollar spot, caused by Sclerotinia homoeocarpa F.T. Bennett, is the most economically important disease of turfgrass. Dollar spot reduces aesthetics and playability of turfgrass, and when left uncontrolled can result in ...
