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 ...
A survey of plant and algal genomes and transcriptomes reveals new insights into the evolution and function of the cellulose synthase superfamily
(BioMed Central, 2014-04)
Background Enzymes of the cellulose synthase (CesA) family and CesA-like (Csl) families are responsible for the synthesis of celluloses and hemicelluloses, and thus are of great interest to bioenergy research. We studied ...
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 ...
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) ...
The Cellulose Synthase Superfamily in Fully Sequenced Plants and Algae
(BioMed Central, 2009-07)
Background: The cellulose synthase superfamily has been classified into nine cellulose synthaselike (Csl) families and one cellulose synthase (CesA) family. The Csl families have been proposed to be involved in the ...
Nucleotide Sequence of Four Ribosomal Protein 127 cDNAs from Growing Axillary Buds of Pea
(American Society of Plant Biologists, 1995)
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 ...
Role of Nitric Oxide and Flavohemoglobin Homolog Genes in Aspergillus nidulans Sexual Development and Mycotoxin Production
(American Society for Microbiology, 2011-08)
Flavohemoglobins are widely distributed in both prokaryotes and eukaryotes. These proteins are involved in reducing nitric oxide levels. Deletion of the Aspergillus nidulans flavohemoglobin gene fhbA induced sexual development ...
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 ...
RMeseeartcah Abrtoiclelic Flexibility Revealed in the Genome of the Cyst-forming α-1 Proteobacterium Rhodospirillum Centenum
(BioMed Central, 2010)
Background: Rhodospirillum centenum is a photosynthetic non-sulfur purple bacterium that favors growth in an anoxygenic, photosynthetic N2-fixing environment. It is emerging as a genetically amenable model organism ...
