Investigating The Effect Of Stratospheric Radiation On Seed Germination And Growth, B. N. Fong, K. V. Newhouse, M. J. Huss, E. Roberts, J. T. Kennon, H. Ali

Journal of the Arkansas Academy of Science

Three seed types: bean (Phaseolus vulgaris), corn (Zea mays) and radish (Raphanus sativus) were flown in a high altitude weather balloon into the mid-stratosphere to investigate the effects of high altitude radiation on germination success and seedling growth. After recovering and planting the seeds, the bean seeds showed lower germination success with exposure to high altitude radiation, and consequently stunted seedling growth. Cord and radish seeds experienced a statistically significant positive effect on germination success form radiation exposure compared to control seeds, but negative effect on seedling growth. Overall, the field experiments presented here support laboratory studies that show radiation …

Arkansas Endemic Flora And Fauna An Update With 13 Additional Species, H. W. Robison, C. T. Mcallister

Journal of the Arkansas Academy of Science

Arkansas supports a diverse variety of endemic biota with most found in the Interior Highlands (Ozarks and Ouachitas) of the state. Since 1988, several compilations have updated the number of endemics known while some former endemic species have been found in other states and subsequently removed from the state list. Here, update to the list by adding 13 taxa, several of which are fish parasites, making a grand total of 139 current endemic species in Arkansas.

Latitudinal Gradient Facilitates Adaptive Population Differentiation Of Campanulastrum Americanum (American Bellflower), Marisa L. Naciuk

Theses and Dissertations

Local adaptation is characterized by higher reproductive fitness by individuals present in their native habitats relative to nonlocals. This study utilized Campanulastrum americanum as a model for assessing whether an environmental gradient can facilitate local adaptation. In particular, I determined if a latitudinal gradient across eastern United States has influenced the phenology and reproductive fitness of five northern and four southern C, americanum populations. These populations were reciprocally transplanted into two common garden sites positioned in the most northern and southern extent of the species distribution: Hastings, MI and Columbus, GA. I observed adaptive population differentiation of northern and southern …

Little Things Reveal The Big Picture, W. John Hayden

Biology Faculty Publications

As enthusiasts who enjoy native plants in natural habitats, we tend to focus on gross morphology— aspects of plant form that can be readily observed with the naked eye or with a hand lens. And there is plenty to see at the gross level. The Flora of Virginia contains 1,269 pages of keys and descriptions devoted to gross morphology of the commonwealth’s botanical treasures. Morphological diversity, however, does not stop at the magnifi cation limit of a hand lens. Light and electron microscopes open up whole new worlds of intricate structure for appreciation and study. And tiny structural details can …

Classifying And Mapping Native Grasslands Of South Dakota's Northern Prairie Coteau And Characterizing Habitat For Dakota Skipper Conservation, Diane M. Narem

Electronic Theses and Dissertations

Native tallgrass prairie is becoming increasingly rare due to conversion and degradation, putting pressure on endemic prairie species such as the federally threatened Dakota skipper butterfly (Hesperia dacotae). To develop a conservation plan for the butterfly in South Dakota, accurate vegetation classification, mapping, and characterization are critical. The objectives of this study were to 1) rank prairie condition, 2) classify and map upland prairie, 3) characterize and compare vegetation at Dakota skipper inhabited and formerly inhabited sites, and 4) identify potential Dakota skipper habitat within a 225 mi2 (58,275 hectares) study area of the SD Prairie Coteau. Condition metrics were …

Plant Functional Traits Of Dominant Native And Invasive Species In Mediterranean-Climate Ecosystems, Jennifer L. Funk, Rachel J. Standish, William D. Stock, Fernando Valladares

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The idea that dominant invasive plant species outperform neighboring native species through higher rates of carbon assimilation and growth is supported by several analyses of global datasets. However, theory suggests that native and invasive species occurring in low-resource environments will be functionally similar, as environmental factors restrict the range of observed physiological and morphological trait values. We measured resource-use traits in native and invasive plant species across eight diverse vegetation communities distributed throughout the five Mediterranean-climate regions, which are drought-prone and increasingly threatened by human activities including the introduction of exotic species. Traits differed strongly across the five regions. In …

Transgenic Wheat Expressing A Barley Udp-Glucosyltransferase Detoxifies Deoxynivalenol And Provides High Levels Of Resistance To Fusarium Graminearum, Xi Li, Sanghyun Shin, Shane Heinen, Ruth Dill-Macky, Franz Berthiller, Natalya Nersesian, Thomas Clemente, Susan Mccormick, Gary J. Muehbauer

Department of Agronomy and Horticulture: Faculty Publications

Fusarium head blight (FHB), mainly caused by Fusarium graminearum, is a devastating disease of wheat that results in economic losses worldwide. During infection, F. graminearum produces trichothecene mycotoxins, including deoxynivalenol (DON), that increase fungal virulence and reduce grain quality. Transgenic wheat expressing a barley UDP-glucosyltransferase (HvUGT13248) were developed and evaluated for FHB resistance, DON accumulation, and the ability to metabolize DON to the less toxic DON-3-O-glucoside (D3G). Pointinoculation tests in the greenhouse showed that transgenic wheat carrying HvUGT13248 exhibited significantly higher resistance to disease spread in the spike (type II resistance) compared with nontransformed controls. Two transgenic …

Utilization of diverse germplasm is required to enhance the genetic variability of cultivars. Opportunity to generate favorable gene combinations can be provided by genetically diverse lines; thus, the probability of creating unique cultivars increases. Genetic diversity analysis of chickpea can give important indications for understanding species relationships and may help in developing and planning breeding programs. Thus, the present investigation was performed to assess the genetic diversity in 125 cultivars of chickpea of Indian origin, among which 42 are resistant and 13 are susceptible to Fusarium wilt and Ascochyta blight. Out of 40 ISSR primers, 26 primers generated 213 polymorphic …

Pollen Morphology Of The Genus Alchemilla L. (Rosaceae) In Iran, Marzieh Beygom Faghir, Farideh Attar, Robabeh Shahi Shavvon, Atefeh Mehrmanesh

Turkish Journal of Botany

This paper reports the morphological characters of 18 Iranian species of the genus Alchemilla using light and scanning electron microscopy. The pollen grains are monad, radially symmetrical, isopolar, or subisopolar; small to medium in size; tri- and tetracolporate; rectangular to cylindrical (from equatorial view) and triangular to circular (from polar view) in outline; and prolate-spheroidal to subprolate and prolate in shape. The exine ornamentation is psilate and microechinate. Based on the exine sculpturing and microechinate distribution pattern, three main types, four subtypes, and two categories of pollen grains were recognized. We used cluster analysis and principal component analysis to determine …

Seed Micromorphology In Dactylorhiza Necker Ex Nevski (Orchidaceae) And Allied Genera, Roberto Gamarra, Pablo Galan, Henrik Aerenlund Pedersen, Emma Ortunez, Ernesto Sanz

Turkish Journal of Botany

Seeds of 21 taxa of the genera Dactylorhiza (incl. Coeloglossum), Gymnadenia (incl. Nigritella) and Pseudorchis were examined by light microscope and SEM. Qualitative and quantitative characters were analyzed. In Dactylorhiza, the seeds are fusiform, but some populations of D. viridis show clavate seeds. According to the ornamentation of the periclinal walls, 3 types of seeds are recognized in this genus. The considerable variation in the seed coat ornamentation pattern in the taxa belonging to majalis, maculata, and praetermissa groups of the genus Dactylorhiza is congruent with the genetic processes that occurred during the history of this genus. Gymnadenia shows clavate …
