Tests of Host, Symbiont
, and Geographical Congruence
Antitumor polyketide biosynthesis by an uncultivated bacterial symbiont
of the marine sponge Theonella swinhoei.
We begin this project by first reviewing the arguments that the individual members of CLOSET can be considered as organisms that are obligate symbionts
with their human hosts.
foili (Acari: Unionicolidae): cryptic species of molluscan symbionts
Despite a reputation as fierce predators on animals captured in their foraging raids, many species of army ants support a rich assemblage of symbionts
that are invertebrates and vertebrates (Holldobler and Wilson, 1990).
The latter role is specific to the symbiotic nature of ECMs, in that the fungi associated with the fine roots can sometimes acquire C from the soil through enzymatic breakdown of organic matter especially during winter months when supplies of photosynthates from host plant are low or unavailable as well as from the tree photosynthates at a rate determined by fungal symbiont
To account for a possible acclimation or adaptation of corals to thermal stress, like shifts to symbiont
algae with a higher thermal tolerance, rather optimistic assumptions have been included in the study.

of Lissoclinum patella.
2003; Huff and Ross, 1975), and chloroplast maturation (Stetler and Laetsch, 1965), and they are involved in a wide range of responses to abiotic and biotic stimuli, including light responses, drought resistance, ion uptake, pathogen defense and symbiont
interaction (Werner and Schmulling, 2009).
Ultra structural aspects of symbiont
relationships in Gentiana lutea L.
We reported some time ago that repair of damage to the photosynthetic apparatus is impaired at elevated temperatures, so preventing photodamage in the symbiont
should confer thermal tolerance to the corals" In the past decade, scientists have identified symbiont
algae in clades from A through H, differing in their genetic and physiological characteristics.
A fungal endophyte may survive in a plant as a symbiont
by providing protective substances (e.
