Investigations of the forage nutritive value of common weeds encountered in Missouri pastures and their relationships with soil fertility
(University of Missouri--Columbia, 2019)
During the 2015, 2016, and 2017 growing seasons, a survey of 63 pastures in Missouri was conducted to determine the effects of selected soil and forage parameters on the density of common annual, biennial, and perennial ...
Molecular characterization of genetic resistance to soybean cyst nematode in soybean line SS97-6946
(University of Missouri--Columbia, 2008)
Soybean Cyst Nematode (SCN) (Heterodera glycine) is the most damaging pest of soybean and estimated annual yield losses are 1.5 billion dollars in USA. Breeding resistant cultivars is the most efficient means to control ...
Identification and characterization of glyphosate-resistant common ragweed
(University of Missouri--Columbia, 2007)
A revolution in production agriculture has occurred over the past decade; the development and use of herbicide-resistant crops. Glyphosate is an effective, broad spectrum and offers flexible application timing with minimal ...
Vegetation management along roadside and railroad right-of-ways
(University of Missouri--Columbia, 2018)
Efficient transportation of freight as well as motorists requires effective control of vegetation on right-of-ways (ROW's). Traditionally on railroad ROW's, residual herbicides are applied early in the growing season with ...
The underlying genetic control of maize root system architecture
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Maize (Zea mays ssp. mays) is one of the most widely cultivated and highest yielding grain crops in the world. The genetic and phenotypic diversity ...
Investigation of rare alleles in maize using the zea synthetic doubled haploid population
(University of Missouri--Columbia, 2019)
have not been extensively studied due to limited resolution and allelic representation issues. Therefore, a new genetic resource, the Zea Synthetic, was created utilizing both teosinte and maize. The Zea Synthetic is a randomly mated synthetic breeding...
Utilizing radiotracer and genetic approaches to determine the regulation of sucrose export in maize leaves
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] To sustain plant growth, development, and ultimately crop yield, carbohydrates must be transported from their site of synthesis in leaves to distant ...
Agronomic and pest interactions in no-till corn and soybean wih fall versus spring herbicide applications
(University of Missouri--Columbia, 2006)
Fall herbicide applications have increased in popularity in recent years. Little is known of how fall herbicide applications impact soil conditions, insect populations, and winter and summer annual weed populations. Few ...
Glyphosate resistance : pollen movement within a common ragweed (Ambrosia artemisiifolia L.) population and herbicide release from common waterhemp (Amaranthus rudis sauer) plants
(University of Missouri--Columbia, 2011)
Common ragweed and Common waterhemp are native, summer annual weeds distributed widely throughout the United States. Both weed species have developed resistance to the broad-spectrum herbicide glyphosate. Research was ...
Molecular genetic analysis of DRO1 genes in soybean

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Under drought conditions, a strong and deep root system provides advantages for exploring and exploiting moisture in deeper soil layers where water is ...
Identification of a novel extracellular adenosine 5'-triphosphate receptor in Arabidopsis thaliana
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In animals, extracellular adenosine 5'-triphosphate (eATP) is a well-studied signaling molecule that is recognized by plasma membrane-localized, P2-type ...
