Ongoing experiments are employing quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR) and mRNA capture to better quantify the changes in host bacteriocyte gene expression between individuals of Ridgeia exhibiting differences in net chemoautotrophy.
We were able to show that chemoautotrophy was occurring in this environment, and we will be examining the potential of heterotrophy in the next field season.
nautilei from the Lau and Fiji Basins (Desbruyeres et al., 1994) and from the Manus Basin (Galchenko et al., 1992), ribulose-1, 5-bisphosphate carboxylase/oxygenase activity provided evidence for the chemoautotrophy of the symbiotic bacteria.
In turn, the animal host provides its symbionts an expanded habitat in which they have access to the substrates of chemoautotrophy ([O.sub.2], C[O.sub.2], and reduced inorganic compounds).
At the other end of the size scale, the studies of the symbiotic bacteria at the base of the food chain in vent environments have highlighted a new kind of thinking about the possible importance of chemoautotrophy in general, and about the significance of similar lithotrophic symbioses in many other environments on the surface of the planet.
