A summary of amplified fragment length polymorphism (AFLP) data from experiments described in Table I. Photographs show rive recipient ramets after transplantation. The areas sampled for DNA extraction and AFLP analysis are delineated and numbered. Asterisks indicate the sites to which the donor zooids were originally transplanted: boxed numbers indicate a sample that contained vascular tissue only. Because of the independent sensitivity of each polymorphic donor locus (illustrated in Fig. 2C). not all of the polymorphic donor loci were seen in each of the transplanted recipient samples. Samples were scored as ( + + ) if they contained over 50% of the polymorphic donor loci, ( + ) it under 50%, and (-) if none were seen, "; indicates that the sample was not determined. Discussion This study produces two interesting results. First, zooid transplantation between noncompatihle Fu/HC B. schlos- seri genotypes does not result in the typical formation of visible PORs (reviewed in Weissman et ai, 1990). Rather, transplantation is followed by a morphological resorption similar to the allogeneic resorption that takes place after fusion between Fu/HC-compatible colonies (Rinkevich and Weissman, 1987). Second, the Fu/HC-noncompatible genotypes continue to thrive within the host, even away from the transplantation zone; this phenomenon had pre- viously been recorded only from Fu/HC-compatible en- counters (Sabbadin and Zaniolo, 1979; Pancer ft <//.. 1995: Stoner and Weissman. 1996). Circumvention of the natural contact areas in B. schlosseri demonstrates that once cells have crossed the allogeneic barriers at the am- pullae, they are no longer subject to elimination from an.
