Effects of harmful algal blooms on competitors: Allelopathic mechanisms of the red tide dinoflagellate Karenia brevis
Because competitive interactions may have led to adaptations enabling bloom-forming phytoplankton to dominate pelagic communities, we explored the allelopathic effects of one red tide dinoflagellate, Karenia brevis, on competing phytoplankton species. Exposure to waterborne compounds from natural K. brevis blooms resulted in growth inhibition or death for four of five co-occurring species teste...
متن کاملCharacterization and isolation of a rotifer-deterrent compound in the red tide dinoflagellate Karenia brevis
Spontaneous phytoplankton blooms cause extensive damage to aquatic ecosystems all over the world. Red Tide, a type of bloom, causes extensive damage in the Gulf of Mexico every year. Red tide is caused by Karenia brevis, a type of phytoplankton known to be especially hazardous because of the harmful toxins it secretes into its environment. Although this phytoplankton species, like many others, ...
متن کاملExtraction and analysis of lipophilic brevetoxins from the red tide dinoflagellate Karenia brevis.
Efficient extraction and accurate analysis of lipophilic brevetoxins (PbTxs), produced by the harmful algal bloom (HAB) species Karenia brevis, are essential when assessing the toxicological potential of this dinoflagellate. One of the most commonly used brevetoxin extraction methodologies employs C18 solid-phase extraction (SPE). In this study, C18 SPEC discs were tested for extraction of spik...
متن کاملChimeric plastid proteome in the Florida "red tide" dinoflagellate Karenia brevis.
Current understanding of the plastid proteome comes almost exclusively from studies of plants and red algae. The proteome in these taxa has a relatively simple origin via integration of proteins from a single cyanobacterial primary endosymbiont and the host. However, the most successful algae in marine environments are the chlorophyll c-containing chromalveolates such as diatoms and dinoflagell...
متن کاملCharacterization of an epoxide hydrolase from the Florida red tide dinoflagellate, Karenia brevis.
Epoxide hydrolases (EH, EC 3.3.2.3) have been proposed to be key enzymes in the biosynthesis of polyether (PE) ladder compounds such as the brevetoxins which are produced by the dinoflagellate Karenia brevis. These enzymes have the potential to catalyze kinetically disfavored endo-tet cyclization reactions. Data mining of K. brevis transcriptome libraries revealed two classes of epoxide hydrola...
