Turkish Journal of Botany

The impact of Fe2+ (iron)toxicity on genomic instability, DNA methylation status, and Long Terminal Repeat Retrotransposons (LTR RTs) polymorphisms on Zea mays is unknown. We investigated the toxicity of Fe2+ using Random Amplified Polymorphic DNA (RAPD), Coupled Restriction Enzyme Digestion-Random Amplification (CRED-RA) and Inter Retrotransposon Amplified Polymorphism (IRAP) assays in Zea mays seedlings, respectively. The results indicated that each dose of FeSO4 (50, 100, 200, and 300 mg/L) had a reducing effect on Genomic Template Stability (GTS) and increasing in RAPD pattern changes (DNA damage). The value of DNA methylation rised gradually depending on FeSO4 doses. Moreover, five LTR RTs …

Involvement Of Poly(Adp-Ribose)Ylation (Parylation) In The Regulation Of Antioxidant Defense System In Arabidopsis Thaliana Under Salt Stress, Rengi̇n Özgür Uzi̇lday

Turkish Journal of Botany

Posttranslational modifications (PTM) are one of the first responses of plants to environmental stress and involve changing the location and activity of proteins in the cell. Addition of poly(ADP-ribose) (PAR) to proteins, poly(ADP-ribose)ylation (PARylation), is a posttranslational modification resulting from the binding of ADP-ribose from NAD+ to target proteins by PAR polymerases (PARP). PARylation is involved in many physiological events in plants including abiotic and biotic stress response. The aim of this work was to understand involvement of PARylation in inducing enzymatic antioxidant defence and alternative electron sinks in response to salinity. For this purpose A. thaliana plants were treated …

Healing Sanctuary, Kammy Downs Jan 2022

Healing Sanctuary, Kammy Downs

Master's Theses or Doctor of Nursing Practice

The natural world has hidden wisdom and resources that are disregarded as we misuse our responsibility to care for them. The benefits of being in tune with nature have been traded for a culture that manipulates nature on the altar of expediency, waste, and unquenchable desire. Healing Sanctuary presents a duality. My work speaks about the relationship between the seen and unseen, represented by ten larger-than-life drawings of medicinal herbal plants that have had a profound physical healing effect on me. At the same time, plants, roots, and seeds create visceral metaphors for mental health. Our accomplishments, outlook on life, …

Garlic Curing: Post-Harvest Nutrient Remobilization From Leaves To Cloves, Mary L. Books Jan 2022

Garlic Curing: Post-Harvest Nutrient Remobilization From Leaves To Cloves, Mary L. Books

Graduate Theses/Dissertations

Garlic (Allium sativum L.) is grown on small and large scales worldwide. After harvesting, garlic undergoes a drying process for long-term preservation, called curing. Some producers cure with leaves intact, while others will remove and discard the leaves, curing only the bulbs. Due to the ability of plants to remobilize nutrients from leaves to underground storage organs, such as bulbs, the curing method of garlic may affect clove nutrient content. This study explores nutrient remobilization responses in garlic when cured with leaves intact compared to leaves separated from bulbs. Four cultivars of garlic, German White, Chesnok Red, Romanian Red, and …

Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi Jan 2022

Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi

Electronic Theses and Dissertations

Globally, canola is the second largest oilseed crop after soybean, which is processed for the commercial production of high value oil. The industrial processing steps for canola oil extraction include preprocessing (cleaning, pressing, flaking, and cooking), mechanical pressing, and/or organic solvents. This process results in large quantities of protein-rich (~ 40% dry basis) meal as a co-product. The meal is used partially in animal diet (<30% inclusion) due to high levels of antinutritional factors (ANFs) such as high fibers, phytic acid, and glucosinolates, and low metabolizable energy. Thus, this research was designed to examine various bioprocessing technologies (i.e., traditional sprouting, solid state fermentation, submerged state fermentation, co-culture fermentation, mild pretreatments, and their combinations) for possible advancement in canola use. Canola seed sprouting for 6-day period led to an increase in protein content and a reduction in ANFs and oil content of sprouts compared to ungerminated seed. Subsequent submerged state fermentation of 6- day old sprouts using three different strains (Aureobasidium pullulans, Trichoderma reesei and Neurospora crassa) further increased protein content and lowered ANFs. Solid-state fermentation of 144 h old sprouts using A. pullulans, N. crassa and T. reesei enhanced the protein content and reduced ANFs of sprouts. Sprouting canola seed for three days helped in hull removal, leading to high protein meal accompanied by low fiber and phytic acid level. Three-day seed sprouting had no effect on oil yield, but free fatty acid content was higher compared to seed oil. Co-culture fermentation of HECM under solid state process showed maximum reduction in fiber content with co-culture of A. pullulans and N. crassa while a combination of A. pullulans and T. reesei promoted the highest GLS and phytic acid reductions compared to other combinations, which indicated the advantage of coculture inoculation over monoculture in terms of ANFs reduction. Mild pretreatment of HECM using deionized water resulted in washed HECM (WHECM) with lower soluble sugars and GLS compared to untreated HECM, whereas protein and amino acid were concentrated due to the removal of soluble components. WHECM compared to HECM showed higher protein digestibility when fed to rainbow trout. Subsequent mono- and coculture fermentation of HECM and WHECM under submerged process resulted in higher protein and amino acid content and lower ANFs levels compared to uninoculated controls. The results of cellulase, endoglucanase and β-glucosidase activity indicated the crucial role of used substrates, fungi, fermentation modes (solid state/submerged stated) and inoculation methods (mono-/co-culture) on enzyme activities.
