Review Of Molecular Biology Of Fungal Development, Mycology Series, Volume 15, Marty Dickman

Department of Plant Pathology: Faculty Publications

Numerous publications, books, and textbooks are available that treat the subject of developmental biology. Far less is available detailing the fungi, an important group of organisms that have implications in a broad variety of contexts from medical to agricultural to food, and of course as model systems for “higher” eukaryotes. This nicely edited book by Osiewacz is an attempt to fill that gap. He has compiled an impressive list of authors, who represent leaders in their respective fields. This gives readers a detailed and current view of a broad array of fungal processes and lifestyles, ranging from saprophytes to pathogens …

We investigated the effects of removing near-stream Rhododendron and of the natural blowdown of canopy trees on nutrient export to streams in the southern Appalachians. Transects were instrumented on adjacent hillslopes in a first-order watershed at the Coweeta Hydrologic Laboratory (35°03′N, 83°25′W). Dissolved organic carbon (DOC), K+, Na+, Ca2+, Mg2+, NO3-- -N, NH4+ -N, PO43---P, and SO42- were measured for 2 years prior to disturbance. In August 1995, riparian Rhododendron on one hillslope was cut, removing 30% of total woody biomass. In October …

The B-Subunit Of The Arabidopsis G Protein Negatively Regulates Auxin-Induced Cell Division And Affects Multiple Developmental Processes, Hemayet Ullah Feb 2003

The B-Subunit Of The Arabidopsis G Protein Negatively Regulates Auxin-Induced Cell Division And Affects Multiple Developmental Processes, Hemayet Ullah

Department of Biology Faculty Publications

Plant cells respond to low concentrations of auxin by cell expansion, and at a slightly higher concentration, these cells divide. Previous work revealed that null mutants of the alpha-subunit of a putative heterotrimeric G protein (GPA1) have reduced cell division. Here, we show that this prototypical G protein complex acts mechanistically by controlling auxin sensitivity toward cell division. Loss-of-function G protein mutants have altered auxin-mediated cell division throughout development, especially during the auxin-induced formation of lateral and adventitious root primordia. Ectopic expression of the wild-type Galpha-subunit phenocopies the Gbeta mutants (auxin hypersensitivity), probably by sequestering the Gbetagamma-subunits, whereas overexpression of …

Rna Interference: Traveling In The Cell And Gaining Functions?, Heriberto D. Cerutti Jan 2003

Rna Interference: Traveling In The Cell And Gaining Functions?, Heriberto D. Cerutti

Center for Plant Science Innovation: Faculty Publications

Double-stranded RNA can induce the degradation of homologous RNAs in organisms as diverse as protozoa, animals, plants and fungi, resulting in post-transcriptional gene silencing. But in some species, RNA-mediated processes can also lead to translational repression, DNA methylation, heterochromatin formation or DNA elimination. In some situations, amplification of the “trigger” double-stranded RNA seems to be required for efficient silencing. These findings imply that RNA-mediated mechanisms can control gene expression at both the transcriptional and the post-transcriptional level, and that they can operate in the nuclear and the cytoplasmic compartments.

Unusual Life Style Of Giant Chlorella Viruses, James L. Van Etten Jan 2003

Unusual Life Style Of Giant Chlorella Viruses, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Paramecium bursaria chlorella virus (PBCV-1) is the prototype of a family of large, icosahedral, plaque-forming, dsDNA viruses that replicate in certain unicellular, eukaryotic chlorella-like green algae. Its 330-kb genome contains ~373 protein-encoding genes and 11 tRNA genes. The predicted gene products of ~50% of these genes resemble proteins of known function, including many that are unexpected for a virus, e.g., ornithine decarboxylase, hyaluronan synthase, GDP-D-mannose 4,6 dehydratase, and a potassium ion channel protein. In addition to their large genome size, the chlorella viruses have other features that distinguish them from most viruses. These features include: (a) The viruses encode multiple …

A Watershed Analysis Of Threemile Pond: Implications For Water Quality And Land Use Management, Colby Environmental Assessment Team, Colby College, Problems In Environmental Science Course (Biology 493), Colby College

Colby College Watershed Study: Threemile Pond (2003)

The 2003 Colby Environmental Assessment Team chose to study the Threemile Pond watershed. The Threemile Pond watershed is located in Vassalboro, China., Windsor, and Augusta, Maine. Threemile Pond is a popular site for recreation and is home to a wide range of flora and fauna. Like all other lakes in Maine, it is a young lake. However, intensive human activity in the watershed contributes a substantial amount of nutrients and the lake has algal blooms annually in the summer months. The purpose of this study was to assess the impact of land use and development on the water quality of …


A Protein Kinase From Colletotrichum Trifolii Is Induced By Plant Cutin And Is Required For Appressorium Formation, M. B. Dickman, Y.-S. Ha, Z. Yang, B. J. Adams, C. Huang Jan 2003

A Protein Kinase From Colletotrichum Trifolii Is Induced By Plant Cutin And Is Required For Appressorium Formation, M. B. Dickman, Y.-S. Ha, Z. Yang, B. J. Adams, C. Huang

Department of Plant Pathology: Faculty Publications

When certain phytopathogenic fungi contact plant surfaces, specialized infection structures (appressoria) are produced that facilitate penetration of the plant external barrier; the cuticle. Recognition of this hydrophobic host surface must be sensed by the fungus, initiating the appropriate signaling pathway or pathways for pathogenic development. Using polymerase chain reaction and primers designed from mammalian protein kinase C sequences (PKC), we have isolated, cloned, and characterized a protein kinase from Colletotrichum trifolii, causal agent of alfalfa anthracnose. Though sequence analysis indicated conserved sequences in mammalian PKC genes, we were unable to induce activity of the fungal protein using known activators …

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Broad-scale information in concert with conservation of individual species must be used to develop conservation priorities and a more integrated ecosystem protection strategy. In 1999 the United States Forest Service initiated an approach for the 1.2 x 106 ha of national grasslands in the Northern Great Plains to fulfill the requirement to maintain viable populations of all native and desirable introduced vertebrate and plant species. The challenge was threefold: 1) develop basic building blocks in the conservation planning approach, 2) apply the approach to national grasslands, and 3) overcome differences that may exist in agency-specific legal and policy requirements. Key …


Agricultural Biotechnology In China: An Unreachable Goal?, Stanley P. Kowalski Jan 2003

Agricultural Biotechnology In China: An Unreachable Goal?, Stanley P. Kowalski

Law Faculty Scholarship

Recently there has been much discussion about the People’s Republic of China’s (PR) investment in and commitment to agricultural biotechnology (agri-biotech). Rapid economic expansion, population growth and technological development are changing the PRC; accompanying these changes is increased demand for high-quality food and fibre. Agri-biotech is optimistically viewed as an important way to meet these demands. Whereas Chinese technological capacity in agri-biotech has advanced significantly over the past decade, it may be unable to meet these challenges. Even when this capacity is combined with good intentions, enlightened policy and large capital outlays, accelerated development of agri-biotech may nevertheless be precluded. …

On The Relationship Between Stomatal Characters And Atmospheric Co2, C. D. Reid, H. Maherali, H. B. Johnson, S. D. Smith, S. D. Wullschleger, R. B. Jackson

Life Sciences Faculty Research

Leaf stomatal characters influence the response of terrestrial evapotranspiration to climate change and are used as proxies for the reconstruction of past atmospheric [CO2]. We examined the phenotypic response of stomatal index (SI), density (SD) and aperture (AP) to rising atmospheric CO2 in 15 species after four years exposure to a field CO2 gradient (200 to 550 μmol mol−1 atmospheric [CO2]) or at three Free Air CO2 Enrichment (FACE) sites. Along the CO2 gradient, SI and SD showed no evidence of a decline to increasing [CO2], while AP decreased slightly. There was no significant change in SI, SD or AP …

The Pseudomonas Syringae Type Iii-Secreted Protein Hopptod2 Possesses Protein Tyrosine Phosphatase Activity And Suppresses Programmed Cell Death In Plants, Avelina Espinosa, Ming Guo, Vincent C. Tam, Zheng Qing Fu, James R. Alfano Jan 2003

The Pseudomonas Syringae Type Iii-Secreted Protein Hopptod2 Possesses Protein Tyrosine Phosphatase Activity And Suppresses Programmed Cell Death In Plants, Avelina Espinosa, Ming Guo, Vincent C. Tam, Zheng Qing Fu, James R. Alfano

Center for Plant Science Innovation: Faculty Publications

The bacterial plant pathogen Pseudomonas syringae possesses a type III protein secretion system that delivers many virulence proteins into plant cells. A subset of these proteins (called Avr proteins) is recognized by the plant’s innate immune system and triggers defences. One defence-associated response is the hypersensitive response (HR), a programmed cell death (PCD) of plant tissue. We have previously identified HopPtoD2 as a type III secreted protein from P. s. pv. tomato DC3000. Sequence analysis revealed that an N-terminal domain shared homology with Avr- PphD and a C-terminal domain was similar to protein tyrosine phosphatases (PTPs). We demonstrated that purified …


Characterization Of Wound-Inducible Genes Encoding Enzymes For Terpenoid Biosynthesis In Medicago Truncatula, Mandy M. Cox Jan 2003

Characterization Of Wound-Inducible Genes Encoding Enzymes For Terpenoid Biosynthesis In Medicago Truncatula, Mandy M. Cox

Inquiry: The University of Arkansas Undergraduate Research Journal

In addition to having numerous applications and pharmaceuticals, terpenoids are an important class of defensive compounds that can accumulate in plants after pathogen infection or injury by insects. Sequences of DNA encoding putative terpene synthases and an oxidosqualene synthase, isolated from insect-damaged Medicago truncatula leaves, were selected from an expressed sequence tag (EST) data base. The cDNA clones were used as radio-labeled probes to analyze gene expression in leaves treated with factors known to trigger a defense response in plants. Transcript levels for all of the genes examined increased in response to artificial wounding, insect herbivory, and methyl jasmonate (meJA) …


Chitosanase May Enhance Anti-Fungal Defense Responses In Transgenic Tobacco, Bill L. Hendrix Jan 2003

Chitosanase May Enhance Anti-Fungal Defense Responses In Transgenic Tobacco, Bill L. Hendrix

Inquiry: The University of Arkansas Undergraduate Research Journal

Fungicides are expensive, dangerous, and can be harmful to the environment, but they are often necessary for profitable farming operations. New technologies may soon allow farmers to replace these chemicals with genetically engineered plants producing antifungal enzymes that degrade fungal cell walls. To explore this option, a Paenbacillus chitosanase gene was cloned, sequenced, and modified for plant expression. The modified gene was delivered to tobacco (Nicotiana tabacum L cv. Xanthine) leaf disks via Agrobacterium tumenfaciens-mediated transformation. The putative GMOs were tested for transgene integration, transcription, and translation. Confirmed transformants were then screened for enhanced responses to a Rhizoctonia solani cell …

Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick Jan 2003

Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick

Theses, Dissertations and Capstones

Soil processes often exhibit spatial heterogeneity within ecosystems and this heterogeneity may influence community structure. This study was conducted to determine spatial patterns and variability of soil nutrients and plant communities within different vegetation types in a stream floodplain in southwestern West Virginia. One 5-m × 5-m site was established in each of three vegetation/drainage types: pasture (PA), old field (OF), and wetland scar (SC). Pasture and SC sites were located ~25 m apart on flat bottomland; the OF site was located on a moderate slope 6.3 m above bottomland, ~200 m from PA and SC. A 10-m × 1-m …
