Growth Potential of Gymnodinium mikimotoi in Gokasho Bay.

Interactions between the red tide dinoflagellates Heterocapsa circularisquama and Gymnodinium mikimotoi in laboratory culture

Interactions between Heterocapsa circularisquama and Gymnodinium mikimotoi, causative red tide dinoflagellates, were investigated using bialgal cultures. G. mikimotoi was killed by H. 21 circularisquama when the initial cell density of each species was set at 200 cells ml . However, cells of H. circularisquama transformed to temporary cysts when the initial cell density of G. 21 mikimotoi was i...

Occurrence of the Parasitic Dinoflagellate Amoebophrya ceratii in Chesapeake Bay Populations of Gymnodinium sanguineum

Chesapeake Bay populations of the red-tide dinoflagellate Gymnodinium sanguineum were regularly infected by the parasitic dinoflagellate Amoebophrya ceratii during the summers of 1988-1991. Infections developed inside the nucleus of G. sanguineum and were always lethal to the host. Parasite generation time was ~ 40 h at 23° C, with the intracellular, trophont phase lasting 39.5 ± 0.3 h, and the...

Bacterial Associates Modify Growth Dynamics of the Dinoflagellate Gymnodinium catenatum

Marine phytoplankton cells grow in close association with a complex microbial associate community known to affect the growth, behavior, and physiology of the algal host. The relative scale and importance these effects compared to other major factors governing algal cell growth remain unclear. Using algal-bacteria co-culture models based on the toxic dinoflagellate Gymnodinium catenatum, we test...

The Potential Mechanism of ZFX Involvement in Cell Growth

Background:The zinc-finger X linked (ZFX) gene encodes a transcription factor that acts as a regulator of self-renewal of stem cells. Due to the role of ZFX in cell growth, understanding ZFX protein-protein interactions helps to clarify its proper biological functions in signaling pathways. The aim of this study is to define ZFX protein-protein interactions and the role of ZFX in cell growth. ...
