Turkish Journal of Botany
Flowers of safflower (Carthamus tinctorius L.) have been widely used in traditional Chinese medicine because of their ability to improve cerebral blood flow. The major active ingredients in safflower are flavonoids. To date, few flavonoid biosynthesis genes have been cloned from this species. In our previous research, four isoform chalcone isomerase genes were screened. In this study, a new chalcone isomerase gene (designated as CtCHI-N) was cloned from a safflower cDNA library. A 696-bp cDNA for CtCHI-N was cloned, and its sequence was subsequently analyzed. The recombinant protein was successfully expressed in a prokaryotic expression system, and the expression of …

Seed Germination Requirements Of Relictic And Broadly-Distributed Populations Of Chaerophyllum Aureum (Apiaceae): Connecting Ecophysiology And Genetic Identity, Alejandro Santiago, Oussama Ahrazem, Lourdes Gómez-Gómez, Miguel Ángel Copete, Raquel Herranz, Pablo Ferrandis
Turkish Journal of Botany
The main goal of this work was to relate the germinative ecology and genetic variability of Chaerolhyllum aureum L., an Apiaceae plant with dormant, underdeveloped embryos at the time of seed dispersal. We compared the seed germination physiology traits between a relictic geographically isolated Mediterranean population (Iberian System; central Spain) and a population located in the main, colder Atlantic Alpine core (Pyrenees; northern Spain). We analyzed both populations? genetic identity in parallel on the basis of ISSR?PCR analyses. Stratification, gibberellin treatment, and seed storage tests showed that C. aureum seeds have deep complex morphophysiological dormancy. The Iberian System population seeds …

Fire And Road Disturbance Impacts On Forest Plant Species And Seed Rain In Table Mountain Fire Arai, Kittitas County, Washington, Jonathan A. Betz
All Master's Theses
Forest communities are in a constant state of change. Disturbance events can alter the physical landscape and create conditions favorable to some species while negatively impacting others. Fire has been a natural, reoccurring source of disturbance in Pacific Northwest forests. Over the past centuries the fire paradigm has changed in favor of fire suppression. Forest roads permit access provide greater access but further fracture forest community’s continuity. The 2012 Table Mountain Fire and road influence have altered the plant community’s seed rain and vegetation. This study measured dispersed seeds and understory vegetation cover as functions of roads and fire intensity. …

Wrinkled Surface On Helical Cell Wall Thickening Of Vessel Elements In Flower Style, Ming Xing, Jian You, Xia Chen
Turkish Journal of Botany
In the present study, wrinkled surfaces were discovered on the cell wall thickenings of helical vessels in the lilac style for the first time. The structure of the wrinkles was formed by cellulose microfibrils, with convex ridges composed of crystalline cellulose and concave grooves composed of amorphous cellulose. The cellulose microfibrils were oriented with the helical cell wall thickenings. The wrinkle morphology was due to the aligned crystalline region of the microfibrils. The wrinkle structure in the flower style might be related to the faster growth rate of style tissues during helix cell wall thickening development. Discovery of the wrinkled …

Application Of Short Tandem Target Mimic (Sttm) Technique For Functional Analysis Of Micro-Rna396 In Transgenic Poplar Trees, Surattana Boonsai
Dissertations, Master's Theses and Master's Reports
Short Tandem Target Mimic (STTM) is a commonly technique used for functional studies of a number of genes in several plant model systems. However, very little is known about application of STTM technique in tree species. In this study, STTM was applied to knock down microRNA396 (miR396) in transgenic poplar trees for the first time. STTM396 expression resulted in dramatic decrease in miR396 expression levels leading to taller plants with larger leaves and larger leaf cell size. Additionally, an expression analysis of growth regulating factor genes (GRFs) that are members of miR396 target gene family showed up-regulation of GRF07 gene …

Broomcorn millet (Panicum miliaceum L.) is the most water-efficient cereal and one of the earliest domesticated plants. Here we report its high-quality, chromosome-scale genome assembly using a combination of short-read sequencing, single-molecule real-time sequencing, Hi-C, and a high-density genetic map. Phylogenetic analyses reveal two sets of homologous chromosomes that may have merged ~5.6 million years ago, both of which exhibit strong synteny with other grass species. Broomcorn millet contains 55,930 proteincoding genes and 339 microRNA genes. We find Paniceae-specific expansion in several subfamilies of the BTB (broad complex/tramtrack/bric-a-brac) subunit of ubiquitin E3 ligases, suggesting enhanced regulation of protein dynamics …

Identification of the nitrate sources that adversely impact groundwater quality is a necessary first step in the control of this major worldwide pollutant. The impact of nitrate leachate from urea-ammonium nitrate (UAN) (50% urea-N, 25% ammonium-N, 25% nitrate-N) fertilizer, whose use has increased dramatically in the last three decades largely because it can be applied through sprinkler irrigation systems to corn in all growth stages, is investigated. The dual isotopes δ15NNO3 and δ18ONO3 were measured in groundwater samples from 39 irrigation wells in two intensively sprinkler-irrigated, corn-growing areas of Nebraska with nitrate-contaminated (N …

Restoring Fire-Grazer Interactions To Pursue Heterogeneity In Sandhills Prairie, Jack R. Arterburn, Dirac L. Twidwell Jr, Carissa L. Wonkka, Walter H. Schacht, David A. Wedin
Department of Agronomy and Horticulture: Faculty Publications
Heterogeneity has emerged as a fundamental principle for grassland management and the importance of environmental heterogeneity for biological diversity has raised questions about the appropriateness of grassland practices that seek to promote uniform grassland structure and composition. Principles of uniformity in grassland management reflect a utilitarian target of “managing for the middle” by minimizing both overgrazing and underutilization while avoiding or preventing fire and other disturbances that consume aboveground biomass. We evaluated pioneering efforts to restore fire-grazer interactions via patch burning in an effort to increase spatial heterogeneity at the patch scale in the Nebraska Sandhills, a sandy soil, mixed-grass …

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 …
Estimation Of Genomic Instability And Dna Methylation Due To Aluminum (Al) Stress In Wheat (Triticum Aestivum L.) Using Ipbs And Cred-Ipbs Analyses, Arash Hossein Pour, Güller Özkan, Özge Nalci, Kami̇l Hali̇loğlu
Turkish Journal of Botany
Aluminum (Al) toxicity is a serious factor restricting crop productivity in acid soil, and Al is the major cause of phytotoxicity. However, the role of Al toxicity in interprimer binding site (iPBS) polymorphism, genomic instability, and DNA methylation has not been fully investigated. In the current study, the effects of different Al concentrations on iPBS polymorphism, genomic instability, and DNA methylation were investigated in seedlings of three wheat cultivars: Haymana 79, Kılçıksız, and Bezostaja 1. A higher aluminum concentration increased the polymorphism rate of the iPBS profile, but decreased genomic template stability in all cultivars . A higher Al concentration …

Competitiveness Of Generalist Plant Populations At A Mine Site, Justin S.H. Wan, Fati̇h Fazlioğlu, Stephen P. Bonser
Turkish Journal of Botany
Plants inhabiting extremely stressful mine site environments tend to be specialized and localized, where they express lower performance than nonmine site plants from adjacent areas. However, such a cost may be concealed. In a previous study at a mine site, we found mine and adjacent nonmine plants of multiple species expressed similar performances in the absence of competition. However, a lower competitive ability may be a concealed driver. We aim to test whether costs under competition could explain specialization. In a glasshouse experiment, we measured the performance (i.e. vegetative and reproductive growth) of mine and nonmine potted plants under competition. …
