Ultrastructural Analysis Of The Digestive Gland Secretory And Absorptive Processes In Nepenthes Glandulifera, Shannon Manuel
Ultrastructural Analysis Of The Digestive Gland Secretory And Absorptive Processes In Nepenthes Glandulifera, Shannon Manuel
Biochemistry, Cellular and Molecular Biology Honors Papers
Nepenthes glandulifera is a carnivorous pitcher plant native to tropical environments, of which the majority live on the islands in the Malay Archipelago where sunlight and water are abundant. The pitcher trap style contains a modified pitfall trap that attracts insects and other small invertebrates through various attractive mechanisms. These plants also contain digestive glands that secrete digestive fluid to break down prey into nutrients for the plant. The digestive fluid, with remarkably unique properties, has been analyzed in relation to multiple areas of study including the development of an enzyme-supplementation strategy for the treatment of celiac disease and the …

Response Surface Analysis Of Genomic Prediction Accuracy Values Using Quality Control Covariates In Soybean, Diego Jarquin, Reka Howard, George L. Graef, Aaron Lorenz
Department of Agronomy and Horticulture: Faculty Publications
An important and broadly used tool for selection purposes and to increase yield and genetic gain in plant breeding programs is genomic prediction (GP). Genomic prediction is a technique where molecular marker information and phenotypic data are used to predict the phenotype (eg, yield) of individuals for which only marker data are available. Higher prediction accuracy can be achieved not only by using efficient models but also by using quality molecular marker and phenotypic data. The steps of a typical quality control (QC) of marker data include the elimination of markers with certain level of minor allele frequency (MAF) and …

Embl2checklists: A Python Package To Facilitate The User-Friendly Submission Of Plant And Fungal Dna Barcoding Sequences To Ena, Michael Gruenstaeudl, Yannick Hartmaring
Biological Sciences Faculty Publications
Background The submission of DNA sequences to public sequence databases is an essential, but insufficiently automated step in the process of generating and disseminating novel DNA sequence data. Despite the centrality of database submissions to biological research, the range of available software tools that facilitate the preparation of sequence data for database submissions is low, especially for sequences generated via plant and fungal DNA barcoding. Current submission procedures can be complex and prohibitively time expensive for any but a small number of input sequences. A user-friendly software tool is needed that streamlines the file preparation for database submissions of DNA …
Remembering Lee W. Lenz (1915–2019)
Remembering Lee W. Lenz (1915–2019)
Aliso: A Journal of Systematic and Floristic Botany
Known primarily for his systematic work on Iris, Dr. Lee Lenz was also known for his taxonomic revision in other monocotyledonous groups such as Yucca, leading to his recognition of Yucca jaegeriana as distinct from the Joshua tree, Y. brevifolia. He was also involved in breeding horticultural forms from California native plants, such as xChiranthofremontia lenzii, and was credited with developing the first red-flowering iris within the Pacific Coast hybrids. Dr. Lenz was Director of Rancho Santa Ana Botanic Garden (now California Botanic Garden) in Claremont, California, from 1960 to 1983. A table lists his …

Closing Yield Gaps For Rice Self-Sufficiency In China, Nanyan Deng, Patricio Grassini, Haishun Yang, Jianliang Huang, Kenneth G. Cassman, Shaobing Peng
Department of Agronomy and Horticulture: Faculty Publications
China produces 28% of global rice supply and is currently self-sufficient despite a massive rural-to-urban demographic transition that drives intense competition for land and water resources. At issue is whether it will remain self-sufficient, which depends on the potential to raise yields on existing rice land. Here we report a detailed spatial analysis of rice production potential in China and evaluate scenarios to 2030. We find that China is likely to remain self-sufficient in rice assuming current yield and consumption trajectories and no reduction in production area. A focus on increasing yields of double-rice systems on general, and in three …

Floristic Quality Assessments Of Remnant Natural Areas In The Greater Grand Rapids, Michigan Region: Evaluating Botanical Change Since The 1890s, Alan W. Stockdale, Garrett Crow, David P. Warners
Floristic Quality Assessments Of Remnant Natural Areas In The Greater Grand Rapids, Michigan Region: Evaluating Botanical Change Since The 1890s, Alan W. Stockdale, Garrett Crow, David P. Warners
Faculty and Professional Research
In 1901, Emma J. Cole, a beloved high school teacher and distinguished botanist, published Grand Rapids Flora. Cole’s floristic inventory remains the most comprehensive botanical study of the greater Grand Rapids, Michigan region, even though this area has experienced significant land- scape alterations since her publication. To address this knowledge gap, in 2014 we embarked on a multiple-year project aimed to discover and reassess the sites Cole described, as well as to catalog other natural remnant locations within the Grand Rapids area. This paper reports botanical invento- ries that were completed at eight sites within Kent County during 2015 and …

Genetic Diversity, Phylogeography And Population Gene Flow Of Tunisian Pistacia Vera L., Sarra Choulak, Zined Marzouk, Khaled Chatti̇, Soumaya Rhouma-Chatti̇, Rim Ouni̇, Noureddine Chatti
Turkish Journal of Botany
The aim of this paper was to determine how the pistachio trees evolve, and the evolving factors that influence pistachio population establishment. For that, we investigated pistachio genetic structure from some regions of Tunisia, by sequencing two noncoding chloroplastic regions (trnL (UAA) and trnL-trnF intergenic spacer). We found strong genetic diversity among groups, with the absence of high differentiation between population pairs. A deep phylogeographical break separated two major clusters: "El-Guetar and "Gafsa/Sidi-Bouzid. This conclusion is proved by the haplotype networks, the phylogenetic trees, and the molecular variance analysis. Different interpretations were proposed to explain this cytoplasm dimorphism, based on …

Quantifying Signpost Usage By Captive Male White-Tailed Deer, Cassie L. Auxt, Eric S. Michel, Jonathan A. Jenks
The Prairie Naturalist
White-tailed deer (Odocoileus virginianus) use rubbing of signpost structures to communicate during the breeding season. Rubbing of signpost structures allows deer to communicate via visual and chemical cues, which allows them to establish dominance hierarchies and maintain hierarchal status throughout the breeding season (Moore and Marchinton 1974, Miller et al. 1981, Hewitt 2011). Once a living tree is rubbed, the exposed light-colored sapwood creates a stark contrast in wooded areas, increasing visibility and further enticing deer to investigate the structure (Oehler et al. 1995). Anatomically, the tubular apocrine sudoriferous glands of white-tailed deer are located at the antler …
The Role Of Continuous Flowering Phenology For In Neotropical Plant-Pollinator Interactions For Use In Conservation, Chelsea Renee Hinton
The Role Of Continuous Flowering Phenology For In Neotropical Plant-Pollinator Interactions For Use In Conservation, Chelsea Renee Hinton
Online Theses and Dissertations
The diversity of mutualistic interactions in the Neotropics exceeds that of all other tropical regions and is posited to result from a unique assemblage of plant species that produce the highest spatio-temporal predictability of food resources. A rare component of the Neotropical flora that contributes largely to the spatio-temporal predictability of food resources is found in understory shrub or tree-let species with a continuous reproductive phenology (i.e. produce fruit and flowers daily during all months of the year). Plant-animal interaction science suggests that plant species with a longer duration of reproductive phenology will accumulate more mutualistic partners over time and …

Soybean [Glycine max (L.) Merr.] seed composition and yield are a function of genetics (G), environment (E), and management (M) practices, but contribution of each factor to seed composition and yield are not well understood. The goal of this synthesis-analysis was to identify the main effects of G, E, and M factors on seed composition (protein and oil concentration) and yield. The entire dataset (13,574 data points) consisted of 21 studies conducted across the United States (US) between 2002 and 2017 with varying treatments and all reporting seed yield and composition. Environment (E), defined as site-year, was the dominant …

Integrated crop–livestock systems have included grazing perennial grasses during the spring and summer and corn (Zea mays L.) residues during the winter. Our objectives were to identify opportunities for expanded corn residue use through grazing and provide an economic assessment for value-added grazing. We estimated the economic value to the crop sector through grazing leased corn residue at over $95 million for Nebraska, South Dakota, Kansas, and North Dakota under current management. Additionally, gross economic value to the livestock sector in these states was estimated at greater than $191 million. Advantages for increased grazing use of corn residue include …

Farming in Nepal mostly represents the hill farming system with the dominance of small-holder farmers. In recent days, farmers in the country are impacted by climate change. Events of surface runoff, landslides, and soil erosions, along with changes in rainfall pattern and intensity have elevated a decline in crop productivity and soil fertility. Considering the situation, a pilot project on Resilient Mountain Village was implemented in Kavrepalanchowk district of Nepal from 2014–2016 with a participatory approach to demonstrate climate-smart practices. These practices include the application of locally prepared bio-fertilizer (named as “jholmal”), green manuring in rice (Oryza sativa L.) …

Department of Agronomy and Horticulture: Faculty Publications
Climate change is a major threat to most of the agricultural crops grown in tropical and sub-tropical areas globally. Drought stress is one of the consequences of climate change that has a negative impact on crop growth and yield. In the past, many simulation models were proposed to predict climate change and drought occurrences, and it is extremely important to improve essential crops to meet the challenges of drought stress which limits crop productivity and production. Wheat and barley are among the most common and widely used crops due to their economic and social values. Many parts of the world …

Obtaining genome-wide genotype information for millions of SNPs in soybean [Glycine max (L.) Merr.] often involves completely resequencing a line at 5X or greater coverage. Currently, hundreds of soybean lines have been resequenced at high depth levels with their data deposited in the NCBI Short Read Archive. This publicly available dataset may be leveraged as an imputation reference panel in combination with skim (low coverage) sequencing of new soybean genotypes to economically obtain high-density SNP information. Ninety-nine soybean lines resequenced at an average of 17.1X were used to generate a reference panel, with over 10 million SNPs called using …

Productivity throughout the North American Great Plains grasslands is generally considered to be water limited, with the strength of this limitation increasing as precipitation decreases. We hypothesize that cumulative actual evapotranspiration water loss (AET) from April to July is the precipitation-related variable most correlated to aboveground net primary production (ANPP) in the U.S. Great Plains (GP). We tested this by evaluating the relationship of ANPP to AET, precipitation, and plant transpiration (Tr). We used multi-year ANPP data from five sites ranging from semiarid grasslands in Colorado and Wyoming to mesic grasslands in Nebraska and Kansas, mean annual NRCS ANPP, and …

Department of Agronomy and Horticulture: Faculty Publications
Fusarium head blight (FHB) is among the most common fungal diseases affecting wheat, resulting in decreased yield, low-density kernels, and production of the mycotoxin deoxynivalenol, a compound toxic to humans and livestock. Human visual analysis of representative wheat samples has been the traditional method for FHB assessment in both official inspection and plant breeding operations. While not requiring specialized equipment, visual analysis is dependent on a trained and consistent workforce, such that in the absence of these aspects, biases may arise among inspectors and evaluation dates. This research was intended to avoid such pitfalls by using longer wavelength radiation than …

Can Ratoon Cropping Improve Resource Use Efficiencies And Profitability Of Rice In Central China?, Shen Yuan, Kenneth G. Cassman, Jianliang Huang, Shaobing Peng, Patricio Grassini
Department of Agronomy and Horticulture: Faculty Publications
Identifying cropping systems with small global warming potential (GWP) per unit of productivity is important to ensure food security while minimizing environmental footprint. During recent decades, double-season rice (DR) systems in central China have progressively shifted into single-crop, middle-season rice (MR) due to high costs and labor requirements of double-season rice. Ratoon rice (RR) has been proposed as an alternative system that reconciliates both high annual productivity and relatively low costs and labor requirements. Here we used onfarm data collected from 240 farmer fields planted with rice in 2016 to evaluate annual energy balance, environmental impact, and net profit of …

Turkish Journal of Botany
Micromorphological characteristics of 13 Trifolium species, which are grown in the province of Bolu, were examined using a scanning electron microscope (SEM). The morphological characteristics determined from the study were subjected to morphometric analyses and their variation spectrums were defined. Tricolporate pollen grains showed two pollen shapes, prolate and subprolate, according to equatorial view. The smallest size of polar axis length (18.00 μm) was found in T. micranthum Viv. from section Chronosemium Ser.; the largest (88.95 μm) was found in T. hirtum All. from section Trifolium L.. Statistically, the smallest seeds were found in T. resupinatum L. from the section …
