Dissection Of Stress Response Networks Regulating Multiple Stresses In Rice, Rafi Shaik
Dissection Of Stress Response Networks Regulating Multiple Stresses In Rice, Rafi Shaik
Dissertations, Master's Theses and Master's Reports - Open
Important food crops like rice are constantly exposed to various stresses that can have devastating effect on their survival and productivity. Being sessile, these highly evolved organisms have developed elaborate molecular machineries to sense a mixture of stress signals and elicit a precise response to minimize the damage. However, recent discoveries revealed that the interplay of these stress regulatory and signaling molecules is highly complex and remains largely unknown. In this work, we conducted large scale analysis of differential gene expression using advanced computational methods to dissect regulation of stress response which is at the heart of all molecular changes …
Factors Influencing The Current And Historical Invasion Trends In The Connecticut College Arboretum, Lillian Fayerweather
Factors Influencing The Current And Historical Invasion Trends In The Connecticut College Arboretum, Lillian Fayerweather
Botany Honors Papers
Invasive species present a growing risk to native ecosystems. It would be impossible to eliminate them, but by learning where they are more likely to occur it may be possible to concentrate resources on removal and management in the most at risk areas. A number of site characteristics may influence invasive species presence and invasion trends. In order to determine what factors affect species presence and historical invasion trends, I utilized data from decennial surveys conducted in the Bolleswood Natural Area of the Connecticut College Arboretum in New London, Connecticut. In 1952, 4 transects were established across the area, composed …

Although most pests of soybeans, Gycine max (L.), in the Northern Great Plains are managed using pesticides, farm management practices that encourage biodiversity offer promising long-term, sustainable solutions for controlling insect and weed pests profitably. The recent invasion of the Northern Great Plains by the soybean aphid (Aphis glycinesMatsumura; Hemiptera: Aphididae) has had potentially important implications for insect communities in soybeans of this region, although recent descriptions of this regional community are scarce. We describe how three pest management systems that vary in the intensity with which they rely on herbicides and insecticides (chemically intensive, reduced chemical, and …
Developmental Variation And Distyly In Hedyotis Caerulea (Rubiaceae), Dennis A. Sampson, Robert A. Krebs
Developmental Variation And Distyly In Hedyotis Caerulea (Rubiaceae), Dennis A. Sampson, Robert A. Krebs
Biological, Geological, and Environmental Faculty Publications
The development of distyly is thought to arise from differential growth patterns in the pin and thrum morphs. However, few detailed studies exist on the early floral development of distylous flowers, and fewer still look at variation in these traits among populations. Buds at multiple stages of development were collected from five populations of Hedyotis caerulea to quantify how pins and thrums diverge with respect to the initiation, rate, and termination of growth between the stamens and stigmas. The growth rate of anthers varied little spatially across five populations and temporally in both pins and thrums, although thrum anthers grew …
Toward A Comprehensive Model Of Photosystem Ii Oxygen Evolving Complex Photoassembly, James Scott Board Ii
Toward A Comprehensive Model Of Photosystem Ii Oxygen Evolving Complex Photoassembly, James Scott Board Ii
Theses, Dissertations and Capstones
Elucidating the mechanism of photoassembly of the oxygen-evolving complex (OEC) will lead to a better understanding of how nature catalyzes water oxidation. Although the temperature dependence of oxygen evolution has been described in the literature [1,2], we have performed a comprehensive study that covers Photosystem II (PSII) activity oxygen evolution in the presence and absence of 2,6-dichloro-1,4benzoquinone (DCBQ) from 5–45°C. In addition, we performed similar measurements for OEC photoassembly in the absence of DCBQ. PSIIenriched particles used for our measurements were prepared according to Berthold, Babcock, and Yocum[3], with modifications from Kolling, et al.[4] The oxygen-evolution of intact BBY particles …

Using Stable Isotope Analysis Of Zooplankton To Document Trophic And Biogeochemical Changes In The San Francisco Estuary, Steven C. Westbrook, Julien Moderan
Using Stable Isotope Analysis Of Zooplankton To Document Trophic And Biogeochemical Changes In The San Francisco Estuary, Steven C. Westbrook, Julien Moderan
STAR Program Research Presentations
Zooplankton represent a vital link between phytoplankton and fish, like the endangered Delta Smelt. Human interferences (nitrates from waste water, flow alteration, invasive species introduction…) have altered the structure of the San Francisco Estuary (SFE) ecosystem. We use stable isotope analysis to improve our knowledge of the planktonic food web in the SFE and gain insights into its evolution over the past decades. We use the ratios of certain isotopes (Nitrogen, Carbon, Sulfur, etc.) in different species of zooplankton to tell us what it is feeding on as well as the trophic level it feeds in. My research focused on …
Phylogenetic Analyses Of Tolpis Adans. (Asteraceae) Reveal Patterns Of Adaptive Radiation, Multiple Colonization And Interspecific Hybridization, Michael Gruenstaeudl, Arnoldo Santos-Guerra, Robert K. Jansen
Phylogenetic Analyses Of Tolpis Adans. (Asteraceae) Reveal Patterns Of Adaptive Radiation, Multiple Colonization And Interspecific Hybridization, Michael Gruenstaeudl, Arnoldo Santos-Guerra, Robert K. Jansen
Biological Sciences Faculty Publications
The plant genus Tolpis (Asteraceae) has been the subject of several investigations on the evolution of oceanic island plants. Its insular species were utilized in studies of artificial hybrid fertility, testing the validity of Baker’s law, the application of DNA barcodes, and the phylogenetic utility of inter-simple sequence repeat markers. Despite this considerable interest in Tolpis, little is known about its phylogenetic history. Past investigations were unable to resolve most of the interspecific relationships, especially within the Canary Islands, where the genus is particularly diverse. Incomplete taxon sampling, the use of ambiguous outgroups and the limited utility of slowly evolving …
