A Novel Cyclophilin B Gene in the Red Tide Dinoflagellate Cochlodinium polykrikoides: Molecular Characterizations and Transcriptional Responses to Environmental Stresses
The marine dinoflagellate Cochlodinium polykrikoides is one of the most common ichthyotoxic species that causes harmful algal blooms (HABs), which leads to ecological damage and huge economic loss in aquaculture industries. Cyclophilins (CYPs) belong to the immunophilin superfamily, and they may play a role in the survival mechanisms of the dinoflagellate in stress environments. In the present ...
متن کاملSurvival and growth of Cochlodinium polykrikoides red tide after addition of yellow loess.
We examined the survival rate of Cochlodinium polykrikoides after yellow loess addition and conducted culture experiments to investigate the possibility that red tides maybe caused by C. polykrikoides individuals that are precipitated when loess is added. At least 15% of the C. polykrikoides cells that precipitated to the bottom layer either by the addition of loess or no addition survived for ...
متن کاملEffect of Higher Plant Essential Oils for the Control of Red Tide Algae Cochlodinium polykrikoides under Laboratory Conditions
Antialgal activity of Zataria multiflora, Satureja khuzistanica and S. rechingeri were evaluated. These plant species are easily cultivable and their algicidal activity make them suitable candidate as biocontrol. This study aimed to identify effective algicidal compounds, practically new algicidal agents from essential oils of plants that could inhibit the growth of red tide microalgae. Prepare...
متن کاملReal time detecting of harmful dinoflagellate Cochlodinium polykrikoides using unmanned surface vehicle in dynamic environments.
Since the first occurrence in 1982, red tides have been observed annually in Korean coastal waters in the form of harmful dinoflagellate Cochlodinium polykrikoides blooms. The distinction in the proposed method for red tide monitoring is the focus on the narrow stripe red tide at an early stage to allow for advanced actions. The distance graph between Head of Narrow Red tide (HNR) and location ...
متن کاملBiochemical responses of fish exposed to a harmful dinoflagellate Cochlodinium polykrikoides.
To elucidate the ichthyotoxic mechanisms of a harmful dinoflagellate Cochlodinium polykrikoides, biochemical responses of fish exposed to blooms were investigated. Particularly, based on our finding that oxidative damages of gill were associated with fish mortality (J. Plankton Res. 21 (1999) 2105-2115), dysfunction of ion-transporting enzymes and secretion of gill mucus of fish exposed to this...
