Investigating The Effects Of Disturbance And Competition On Establishment, Growth, And Reproduction Of The Endangered Ripariosida Hermaphrodita, Daniel Engelking
Theses and Dissertations (Comprehensive)
Ripariosida hermaphrodita (Virginia Mallow) is a perennial riparian plant with broad, maple-like leaves. It grows up to three meters high and is often found in large clonal patches, but sexually reproduces readily. While this plant may seem like a redoubtable competitor when growing in large colonies, it is declining across its range in North America. The only known occurrences in Canada are in southern Ontario. Prior to this study, no new populations had been recorded even though one of the known populations produces copious amounts of viable seed with potential to disperse. There are many hypotheses for its rarity, but …

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 …

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 …
Activated Charcoal Alleviates Fluoride Stress By Restricting Fluoride Uptake And Counteracting Oxidative Damages In The Rice Cultivar Mtu1010, Ankur Singh, Swarnavo Chakraborty, Aryadeep Roychoudhury
Turkish Journal of Botany
This work was aimed to explore the efficacy of activated charcoal (5 mg g-1 soil) in abating fluoride (25 mg L-1 NaF) stress in rice seedlings, since the protective role of charcoal is widely reported against other forms of abiotic stress. Application of NaF solution reduced germination rate, dry and fresh weight, and shoot and root length of seedlings. Extensive fluoride accumulation lowered the chlorophyll level along with higher electrolyte leakage and formation of H2 O2 , malondialdehyde, and methylglyoxal. Administration of activated charcoal lowered the extent of oxidative damages by inhibiting the uptake of fluoride ions. Exogenous …

Histochemical And Surface Microstructural Analyses Of Floral Cuticles Provide Evidence For Differential Behaviors In Scent Volatiles Emission In Two Tuberoses (Agave Amica (Medik.) Theide And Govaerts) Cultivars From Asparagaceae, Raktim Bhattacharya, Adinpunya Mitra
Turkish Journal of Botany
Two popular cultivars of tuberose (Agave amica (Medik.) Theide and Govaerts syn. Polianthes tuberosa L.) from the family Asparagaceae, widely cultivated for floricultural purposes are ,'Calcutta Single' (CS) and 'Calcutta Double' (CD). It was evidenced that CS flowers emit intense scent volatiles as compared to CD flowers, while CD flowers retained higher contents of internal pool of scent volatiles than CS flowers. Such contrasting observations between the flowers of two cultivars suggest the role of possible barriers such as cuticles that prevent the emission of scent volatiles. The cuticular structure of both cultivars was studied using different histochemical approaches, …

Csi Botany: Dna Barcode “Fingerprints” Identify Cryptic Urban Flora, Luis R. Vega
Theses and Dissertations
As short genomic markers, DNA barcodes can play a role in conservation by identifying cryptic species and hybrids when morphological approaches fall short. Here we present our application of barcodes to the identities of two wetland taxa as part of an ongoing floristic inventory of Van Cortlandt Park (VCP), Bronx, NY. Previous barcode data by Marriott et al. (2018) identified the VCP lake water lily as the exotic Nymphaea alba, rather than the native N. odorata as historically described. In addition, cattails in the park were historically identified as the native Typha latifolia and the exotic T. angustifolia …

Effect Of Soil Transplantation On Fungal Communities During Restoration, Thomas Luehl
All Master's Theses
Ectomycorrhizal fungi are integral parts of natural ecological systems that provide access to nutrients that would otherwise be unavailable by forming symbiotic relationships with plants. Relationships with ectomycorrhizal fungi are known to improve plant growth rate, increase plant resistance to pathogens, and improve survival. Current revegetation practices often ignore this relationship between fungi and plants. During the revegetation of the Interstate 90 Keechelus Lake wildlife overcrossing (Easton, WA), soil from forest sites adjacent to the restoration area were collected and used to inoculate a set of experimental plots to determine whether ectomycorrhizal fungi would become established in the plots and …
