Osmoregulation in anthozoan-dinoflagellate symbiosis.
Endosymbiosis creates a unique osmotic circumstance. Hosts are not only responsible for balancing their internal osmolarity with respect to the external environment, but they must also maintain a compatible osmotic environment for their endosymbionts, which may themselves contribute to the net osmolarity of the host cell through molecular fluxes and/or exchange. Cnidarian hosts that harbor intr...
متن کاملDiel expansion and contraction patterns vary among anthozoan
anthozoan species, including reef-building corals (Kawaguti, 1954; Porter, 1974; Lasker, 1979), gorgonians (Wainwright, 1967) and sea anemones (Pearse, 1974; Sebens and Deriemer, 1977). Most reef corals expand their tentacles only at night (Lewis and Price, 1975; Porter, 1974). A few species expand their tentacles during daytime and several species have continuously expanded tentacles (Eguchi, ...
متن کامل13-P034 Notch signaling in the Anthozoan Cnidarian Nematostella vectensis
organization is its bilateral symmetry, most evident at the level of the vertebrae and skeletal muscles. Here, we show that Rere (Atrophin2)-deficient mouse embryos form asymmetrical somites in a temporally defined window. During the time period spanning the formation of somites 7 to 13 in Rere mutants, there is a lack of left–right coordination of the oscillatory behavior of the cyclic genes a...
متن کاملThe Symbiotic Anthozoan: A Physiological Chimera between Alga and Animal.
The symbiotic life style involves mutual ecological, physiological, structural, and molecular adaptations between the partners. In the symbiotic association between anthozoans and photosynthetic dinoflagellates (Symbiodinium spp., also called zooxanthellae), the presence of the endosymbiont in the animal cells has constrained the host in several ways. It adopts behaviors that optimize photosynt...
متن کاملHealing beauty?
Beauty—as the saying goes—is in the eye of the beholder, though this relativistic insight has not stopped humans from spending more than 6,000 years striving to artificially enhance their looks. From ancient Egypt and Sumer until today, the quest for beauty is recorded in our literature, music and art. Even today, many women and men devote considerable amounts of time and money to selecting and...
