Eutrophication and Harmful Algal Blooms: A Scientific Consensus.
In January 2003, the US Environmental Protection Agency sponsored a "roundtable discussion" to develop a consensus on the relationship between eutrophication and harmful algal blooms (HABs),Expand
A mRNA signal for the type III secretion of Yop proteins by Yersinia enterocolitica.
The signal that leads to the type III secretion of Yop proteins appears to be encoded in their messenger RNA rather than the peptide sequence. Expand
The search for organic substances and inorganic volatile compounds in the surface of Mars
A total of four Martian samples, one surface and one subsurface sample at each of the two Viking landing sites, Chryse Planitia and Utopia Planitia, have been analyzed for organic compounds by a gasExpand
Pseudomonas syringae Hrp type III secretion system and effector proteins.
Pseudomonas syringae secretes HopPsyA and AvrPto in culture in a Hrp-dependent manner at pH and temperature conditions associated with pathogenesis, indicating that a universal targeting signal is recognized by the type III secretion systems of both plant and animal pathogens. Expand
Two independent type III secretion mechanisms for YopE in Yersinia enterocolitica
Two separate secretion signals contained in YopE were identified, each of which were sufficient but not necessary for the secretion of reporter molecules. Expand
Steel-Dickie mutation encodes a c-kit ligand lacking transmembrane and cytoplasmic domains.
These studies provide a molecular basis for explaining the Sld phenotype, a description of a germ-line mutation in the transmembrane and cytoplasmic domains of a membrane- bound growth factor, and in vivo evidence for the importance of membrane-bound forms of growth factors in mammalian development.

Identification and Characterization of Three Differentially Expressed Genes, Encoding S-Adenosylhomocysteine Hydrolase, Methionine Aminopeptidase, and a Histone-Like Protein, in the Toxic
The identification of an additional 21 genes with various cell cycle-related DD patterns provides evidence for the importance of pretranslational or transcriptional regulation in dinoflagellates, contrary to previous reports suggesting the possibility that translational mechanisms are the primary means of circadian regulation in this group of organisms. Expand
Toxin composition variations in one isolate of the dinoflagellate Alexandrium fundyense.
It is demonstrated here that dramatic changes in toxin composition do occur in one isolate of Alexandrium fundyense, and in nitrogen- and phosphorus-limited semi-continuous cultures, toxin composition varied systematically with growth rate. Expand
Levels of β-Mannan in Soybean Meal
Beta-mannan has clearly been shown to be deleterious to poultry and animal performance and a survey of its concentration in SBM confirmed that concentrations are higher in nondehulled samples than in dehulling samples. Expand
The economic effects of harmful algal blooms in the United States: Estimates, assessment issues, and information needs
During the last several decades, harmful algal bloom (HAB) events have been observed in more locations than ever before throughout the United States. Scientists have identified a larger number ofExpand
