(University of Missouri--Columbia, 2019)
quality indicators. The four-year experiment consisted of five weed treatments (propane flaming, cultivation, between-row mowing, hot water spraying, and weed control) for two grain crops, soybean (Glycine max L.), and corn (Zea mays L.) grown in rotation...
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 ...
Novel approaches in macroinvertebrate biomonitoring
(University of Missouri--Columbia, 2008)
The increasing popularity of benthic macroinvertebrate use for biological monitoring and assessment of lotic systems calls for new applications for regions with a lesser known fauna and an overall better understanding of ...
Photosynthesis and heat tolerance of soybean
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Photochemical Reflectance Index (PRI) is determined from canopy spectral reflectance measurements and can provide important information about photosynthesis. The PRI can...
Characterization of the insect cuticle sclerotization hormone bursicon and bursicon-regulated genes in the house fly Musca domestica
(University of Missouri--Columbia, 2008)
Bursicon is a neurohormone that regulates the cuticle sclerotization and wing expansion process in insects. Bursicon is a heterodimeric cystine knot protein containing two subunits, burs [alpha] and burs [beta], which are ...
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 ...
Characterization of a diverse USDA collection of wild soybean (glycine soja siebold & zucc.) accessions and subsequent mapping for seed composition and agronomic traits in a RIL population
(University of Missouri--Columbia, 2018)
been undertaken to introduce novel genetic diversity present in wild soybean (Glycine soja Siebold & Zucc.) into new elite cultivars, in both public and private applied soybean breeding programs. The objectives of this research were to evaluate...
Development of high protein soybean experimental lines with enhanced sulfur amino acid content
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Soybean is one of the most important field crops grown in the United States. Commercial soybeans contain about 36 - 40 [percent] protein and 18 - 20 ...
Characterization of resistance to tombusvirus in nicotiana species
(University of Missouri--Columbia, 2009)
Our lab studies resistance to tombusviruses such as Tomato bushy stunt virus (TBSV), Cymbidium ringspot virus (CymRSV), and Cucumber necrosis virus (CNV) in Nicotiana species, according to the ''gene for gene'' model, which ...
Fine mapping and candidate gene identification of a soybean seed protein and oil QTL from a wild soybean accession and linkage analysis for whole plant biomass, carbon, nitrogen, and seed composition using a RIL mapping population
(University of Missouri--Columbia, 2021)
-term improvement of agronomic and seed compositional traits. In both public and private soybean breeding programs, the introgression of wild soybean (Glycine soja Siebold and Zucc.) genes has been utilized to incorporate novel genetic diversity. In our study, 3...
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 ...
