Applied genomics toward targeted improvement of soybean
(University of Missouri--Columbia, 2021)The abundance of genomic data produced by the research community in the last decade has offered an unprecedented view into the variation present in the soybean genome and has been exploited to uncover the genetic architecture ... -
Arabidopsis and Xanthomonas campestris pv. campestris two model organisms in plant pathology
(University of Missouri--Columbia, 2022)Causative agent of black rot of crucifers, Xanthomonas campestris pv. campestris (Xcc), is a rod-shaped Gram-negative bacterium that belongs to the [gamma]-subdivision of Proteobacteria. It was first described in 1889 by ... -
An assessment of UAV technology and shattercane population dynamics to improve pest management
(University of Missouri--Columbia, 2023)Unmanned aerial vehicles (UAVs) outfitted for pesticide application have the potential to improve application efficiency under conditions challenging for traditional, ground-based equipment. UAV-applied treatments had 21-32 ... -
Characterization of diverse soybean genotypes for phosphorus uptake and use efficiency
(University of Missouri--Columbia, 2021)Soybean (Glycine max L. Merrill) is one of the most important legume crops grown worldwide. However, without phosphorus (P) fertilization, soybean yields often are limited by phosphorus availability. Phosphorus is an ... -
Computational methods to identify ionomic candidate genes in plants
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 12/1/2024] High throughput phenotyping and quantitative genetics have enabled researchers to identify genetic regions associated with changes in phenotype. However, going from GWAS loci to candidate genes ... -
Conserving monarch butterflies through habitat management and policy
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 8/1/2024] Monarch butterflies (Danaus plexippus) are in decline, with a 91 percent population reduction since 1996. Habitat loss is a major contributor to this decline. The milkweed plant (Asclepias spp.) ... -
The development of the Heterodimeric enhanced Yeast-One Hybrid (HD-eY1H) assay
(University of Missouri--Columbia, 2022)Life can be summarized as a continuous struggle to maintain homeostasis - or balance - despite dynamic changes in environmental conditions. Changes in gene expression is one of the many ways organisms can interact and ... -
Drainage water management practices affect water quality, soil properties, and crop production
(University of Missouri--Columbia, 2023)Several agricultural management practices such as terrace construction, cover crops (CC), drainage water recycling (DWR), free drainage (FD), and 4R nitrogen (N) management can influence water quality, soil properties, and ... -
Effects of stress, genetics, and environment on microbiome composition in western corn rootworm (Diabrotica virgifera virgifera Leconte)
(University of Missouri--Columbia, 2023)Increased study of microbiomes illuminated the diversity of roles microorganism play across ecosystems. For agricultural systems, microbiomes represent a new frontier to potentially improve plant, animal, and human health, ... -
Establishment of native plant species for livestock forage in silvopasture systems
(University of Missouri--Columbia, 2022)Incorporating sustainable agriculture practices and environmental stewardship into existing forage-livestock systems is growing in popularity. This project takes a novel approach incorporating native rather than introduced ... -
Estimation of crop residue cover in high-resolution RGB images using features from a pre-trained convolutional neural network
(University of Missouri--Columbia, 2022)Plant residue on the soil surface increases the sustainability food and fiber production in agricultural systems. Automated assessments of residue cover based on imagery has the potential to reduce labor and human bias ... -
Evaluation of harvest weed seed destruction in U.S. soybean and a survey of waterhemp populations response to dicamba and glufosinate
(University of Missouri--Columbia, 2022)"One impact mill commonly used in commercial production in Australia is known as the Seed Terminator[trademark]. Independent research has shown the Seed Terminator[trademark] to be an effective HWSC tool in Australian grain ... -
Genetic mapping of soybean cyst nematode resistance and evaluation of resistant germplasm in soybean and pennycress
(University of Missouri--Columbia, 2022)A single mode of genetic resistance derived from PI 88788 (rhg1-b) has dominated the $57.5 B US soybean market for almost three decades. The breakdown of resistance and selection of virulent nematode populations poses a ... -
The impact of economically important Grapevine viruses on yield and berry juice quality in the hybrid grape cultivars Norton and Chardonel
(University of Missouri--Columbia, 2022)Three grapevine viruses are considered to pose great threats to grape and wine production in the United States. Those viruses are Grapevine vein clearing virus (GVCV), Grapevine leafroll-associated virus 3 (GLRaV-3) and ... -
Impact of electrocution on weed control and weed seed viability in soybean
(University of Missouri--Columbia, 2022)Field experiments were conducted in 2020 and 2021 to test the effectiveness of electrocution on several weeds commonly encountered in Missouri soybean production using an implement known as The Weed Zapper[trademark]. The ... -
Increasing methionine content of soybean using CRISPR/Cas9 and developing machine learning predictive models
(University of Missouri--Columbia, 2022)Soybean [Glycine max (L.) Merr.] is an important protein source for both humans and animals. Its relatively low cost combined with its excellent nutritive value has enabled soybeans to attain elite stature as the world's ... -
Indirect effects of invasive insect management on forest insect abundance
