Are Annulate Lamellae in the Drosophila Embryo the Result of Overproduction of Nuclear Pore Components?
(Rockefeller University Press, 1984-02)Annulate lamellae are cytoplasmic organelles composed of stacked sheets of membrane containing pores that are structurally indistinguishable from nuclear pores. The functions of annulate lamellae are not well understood ... -
The Role of Carbohydrate in Maintaining Extensin in an Extended Conformation
(American Society of Plant Biologists, 1986)Monomers of the plant cell wall glycoprotein extensin are secreted into the wall where they become cross-linked to each other to form a rigid matrix. Expression of the extensin matrix is correlated with the inhibition ... -
Cross-Linking Patterns in Salt-Extractable Extensin from Carrot Cell Walls
(American Society of Plant Biologists, 1986)Extensins are hydroxyproline-rich glycoproteins (HRGPs) found in the primary cell walls of dicots. Extensin monomers are secreted into the wall and covalently bound to each other, presumably by isodityrosine (IDT) ... -
A Second Extensin-Like Hydroxyproline-Rich Glycoprotein from Carrot Cell Walls'
(American Society of Plant Biologists, 1987)The insoluble extensin matrix of dicot cell wails has been studied most fruitfully by examining the salt-extractable precursors to this matrix. Multiple extensin-like hydroxyproline-rich glycoproteins (HRGPs) have been ... -
Soybean Leaves Contain Multiple Lipoxygenases
(American Society of Plant Biologists, 1991)Chromatofocusing of soybean (Glycine max L.) leaf lipoxygenases revealed three distinct peaks of activity. Based on their isoelectric points (pis), pH optima, and mutant analysis it appears that the leaf isozymes are ... -
Expression of a Ribosomal Protein Gene in Axillary Buds of Pea Seedlings
(American Society of Plant Biologists, 1992)Axillary buds of intact pea seedlings (Pisum sativum L. cv Alaska) do not grow and are said to be dormant. Decapitation of the terminal bud promotes the growth of these axillary buds, which then develop in the same ... -
Nucleotide Sequence of Four Ribosomal Protein 127 cDNAs from Growing Axillary Buds of Pea
(American Society of Plant Biologists, 1995) -
Microevolution in Island Water Snakes
(American Institute of Biological Sciences, 1997-05)Examples presented demonstrate that evolutionary outcomes depend not only on those processes that operate within populations(e,g.,selection) but also on interactions (via gene flow) among populations. Factors ... -
Characterization of the recD gene of Neisseria gonorrhoeae MS11 and the Effect of recD Inactivation on Pilin Variation and DNA Transformation
(Society for General Microbiology, 1999-02)Pilin antigenic variation in Neisseria gonorrhoeae may result following intrachromosomal recombination between homologous pi/ genes. Despite extensive study, recA is the only previously characterized gene known to ... -
Phylogenetics of Paniceae (Poaceae)
(Botanical Society of America, 2001-11)Paniceae demonstrate unique variability of photosynthetic physiology and anatomy, including both non-Kranz and Kranz species and all subtypes of the latter. This variability suggests hypotheses of independent origin or ... -
Forensic Entomology for the Laboratory-Based Biology Classroom
(University of California Press, 2002-02)Article describes the use forensic entomology in a laboratory-based biology classroom, where it can help students to explore many of the physiological processes that occur in all living organisms, as well as basic principles ... -
Complex Transitions Between C3 and C4 Photosynthesis During the Evolution of Paniceae: A Phylogenetic Case Study Emphasizing the Position of Steinchisma Hians (Poaceae), A C3-C4 Intermediate
(University of Chicago Press, 2003)A two-tiered, nested molecular phylogenetic study of panicoid grasses to explore character state transitions between the C3 and C4 adaptive syndromes is presented. A broad survey of 92 panicoid species was sampled for ... -
TCA Microsatellite Repeats in the 5’UTR of the Sat5 Gene of Wild and Cultivated Accessions of Pisum and of Four Closely Related Genera
(University of Chicago Press, 2004)PsSat5, a cDNA clone from Pisum sativum cv. Alaska, contained a microsatellite consisting of 15 TCA repeats within the 59UTR. This SSR microsatellite was immediately upstream of the presumptive ATG start codon. PCR ... -
Characterization of the Aspergillus parasiticus delta12-desaturase Gene: A Role for Lipid Metabolism in the Aspergillus/plant Interaction
(Society for General Microbiology, 2004-09)In the mycotoxigenic oilseed pathogens Aspergillus flavus and Aspergillus parasiticus and the model filamentous fungus Aspergillus nidulans, unsaturated fatty acids and their derivatives act as important developmental ... -
The Mitochondrial Genome of the Peronosporomycete Saprolegnia Ferax: Organization, Gene Content, and Nucleotide Sequence
(Mycological Society of America, 2004-09)The mitochondrial genome of the peronosporomycete water mold Saprolegnia ferax has been characterized as a 46 930 bp circle containing an 8618 bp large inverted repeat (LIR). Eighteen reading frames encode identified ... -
Redox Signaling in Colonial Hydroids: Many Pathways for Peroxide
(The Company of Biologists, 2005-01)Studies of mitochondrial redox signaling predict that the colonial hydroids Eirene viridula and Podocoryna carnea should respond to manipulations of reactive oxygen species (ROS). Both species encrust surfaces with ... -
The Temporal and Spatial Scale of Microevolution: Fine-scale Color Pattern Variation in the Lake Erie Watersnake
(Evolutionary Ecology, Ltd., 2006)Question: What is the temporal and spatial scale of microevolution? Hypotheses: The combined effects of natural selection and gene flow result in variation in heritable traits on fine spatial and geographic scales. Organism: ... -
Preserving Madagascar’s Natural Heritage: The Importance of Keeping the Islands’s Fossils in the Public Domain
(Madagascar Wildlife Conservation, 2006)Article argues for the development of adequate repositories and support infrastructure in Madagascar to safeguard and display the country’s vertebrate fossil collections; doing so would ensure the preservation and appreciation ... -
On the Origin of Microbial ORFans: Quantifying the Strength of the Evidence for Viral Lateral Transfer
(BioMed Central, 2006-08)Background:The origin of microbial ORFans, ORFs having no detectable homology to other ORFs in the databases, is one of the unexplained puzzles of the post-genomic era. Several hypothesis on the origin of ORFans have ... -
Multicellular Redox Regulation in an Early-Evolving Animal Treated with Glutathione
(University of Chicago Press, 2007-05)Redox signaling has emerged as a unifying theme in many seemingly disparate disciplines. Such signaling has been widely studied in bacteria and eukaryotic organelles and is often mediated by reactive oxygen species (ROS). ...
