A molluscan class struggle: exploring the surprisingly uneven distribution of chemosymbiosis among two major mollusk groups

چکیده
Many bivalves and gastropods from marine reducing environments such as deep ocean hydrothermal vents seeps host chemosynthetic bacteria in a nutritional symbiosis. Despite their functional similarities, the distribution of chemosymbiosis these two mollusk classes is surprisingly uneven: number bivalve species known to symbionts more than twenty times that gastropods, chemosymbiotic are reported far greater diversity habitats. Here we explore potential drivers for this trend, including but not limited physiological differences, habitat characteristics, sampling bias. Sampling bias likely contributes magnitude observed discrepancy, posit phenomenon itself reveals how intrinsic (e.g. morphology) extrinsic organic matter availability) factors might have shaped extant gastropod associations. These observations also serve an impetus increasing investigation into other mollusks chemically better understand evolution ecology among molluscan hosts.

We have examined TCR V beta expression in a collection of wild mice. Many of the mice were homozygous for a large deletion at the V beta locus, and many animals also suppressed expression of several V betas using self superantigens. Expression of V beta 8.2 was unexpectedly suppressed by a self superantigen in some wild mice, which was due to the presence in these animals of a variant V beta 8....
