Monoclonal Antibodies Against Methyl Glucuronoxylan Epitopes For Understanding Xylan Structure And Modification, Utku Avci Jan 2023

Monoclonal Antibodies Against Methyl Glucuronoxylan Epitopes For Understanding Xylan Structure And Modification, Utku Avci

Turkish Journal of Botany

Lignocellulosic biomass is an abundant and renewable source that could be utilized for production of many bioproducts. It mainly consists of cellulose, hemicellulose, and lignin, all of which come together to form a recalcitrant wall that impedes production of bioproducts. In order to overcome the recalcitrant nature of the biomass, it is important to fully understand how cell wall components are synthesized and assembled. Xylan is one of the hemicellulosic components of the wall that contributes to recalcitrance. Xylan has substitutions on the backbone that are formed by the orchestration of many enzymes. For example, glucuronoxylan methyltransferases are responsible for …

Competition And Herbivory Influence The Survival, Growth, And Physiology Of Native Tree Seedlings In The Kentucky Inner Bluegrass Savanna-Woodland, James D. Shaffer

Theses and Dissertations--Biology

Terrestrial plant communities are shaped by competition for resources, herbivory, and abiotic processes. Savanna systems represent a dynamic coexistence of contrasting life forms (grasses and trees) shaped by competition and disturbance. The Kentucky Inner Bluegrass Savanna-Woodland (KIBSW) is described as an open woodland of shade intolerant species; however, climatic, and edaphic conditions can support closed-canopy forest. After European pioneer settlement (c1750-1800), over 99% of “savanna-woodlands” have been lost. KIBSW remnants are experiencing a recruitment failure, leading to a dominance shift in tree communities. I researched how tree-grass competition and mammalian herbivory influence KIBSW regeneration and maintenance. The KIBSW does not …

Department of Agronomy and Horticulture: Faculty Publications

Understanding the genetic basis responding to nitrogen (N) fertilization in crop production is a long-standing research topic in plant breeding and genetics. Albeit years of continuous efforts, the genetic architecture parameters, such as heritability, polygenicity, and mode of selection, underlying the N responses in maize remain largely unclear. In this study, about n = 230 maize inbred lines were phenotyped under high N (HN) and low N (LN) conditions for two consecutive years to obtain six yield-related traits. Heritability analyses suggested that traits highly responsive to N treatments were less heritable. Using publicly available SNP genotypes, the genome-wide association study …

Forage Grass Growth Habit And Allelopathy In Birdsfoot Trefoil Germination And Establishment, Nathan El Blake Jan 2023

Forage Grass Growth Habit And Allelopathy In Birdsfoot Trefoil Germination And Establishment, Nathan El Blake

Graduate Theses, Dissertations, and Problem Reports (ETD)

Birdsfoot trefoil (Lotus corniculatus L.) (BFT) is a high quality, tanniniferous forage legume that has been shown to mitigate gastrointestinal nematode (GIN) infection in sheep. Reliable establishment of birdsfoot trefoil in existing pastures is difficult due to BFT’s poor seedling vigor, susceptibility to crown and root rot, and, perhaps chiefly, competition from other pasture plants. Most existing pastures in the Northeastern United States are primarily composed of cool-season grasses, many of which can be highly competitive. A common form of interplant competition is allelopathy, which occurs when secondary metabolites produced by a plant inhibit a necessary growth process of …

Boron Toxicity Induces Sulfate Transporters At Transcriptional Level In Arabidopsis Thaliana, Ceyhun Kayihan, Emre Aksoy, Su Naz Mutlu Jan 2023

Boron Toxicity Induces Sulfate Transporters At Transcriptional Level In Arabidopsis Thaliana, Ceyhun Kayihan, Emre Aksoy, Su Naz Mutlu

Turkish Journal of Botany

Plants activate glutathione (GSH)-dependent detoxification pathways at biochemical and molecular levels under boron (B) toxicity. Sulfate uptake and transport are necessary for GSH biosynthesis in plants. Therefore, the transcriptional regulation of some sulfate transporters was determined in this study to clarify the importance of these transporters in leaf and root tissues of Arabidopsis thaliana under toxic B conditions. The expression level of SULTR1;3 was dramatically increased in leaf and root tissues under moderate and severe toxic B conditions, suggesting source-to-sink sulfate translocation under B toxicity. Stable expression levels of SULTR2;1, SULTR2;2, and low SULTR3;5 expression might restrict the sulfate movement …
