    Notes: Abstract. Microsatellite length variation was investigated at a highly variable microsatellite locus in four species of Apodemus. Information obtained from microsatellite allele sequences was contrasted with allele sizes, which included 18 electromorphs. Additional analysis of a 400-bp unique sequence in the flanking region identified 26 different haplotype sequences or ``true'' alleles in the sample. Three molecular mechanisms, namely, (1) addition/deletion of repeats, (2) substitutions and indels in the flanking region, and (3) mutations interrupting the repeat, contributed to the generation of allelic variation. Size homoplasy can be inferred for alleles within populations, from different populations of the same species, and from different species. We propose that microsatellite flanking sequences may be informative markers for investigating mutation processes in microsatellite repeats as well as phylogenetic relationships among alleles, populations, and species.

    Notes: Abstract This report has been prepared in response to a request from the U.S. Department of Energy's (DOE) Office of Fusion Energy Sciences to consider possible alternatives on reduced cost options for “next-step” devices. A central focus of next-step devices is the study of “burning” plasmas, which explore the impact of substantial fusion energy production via the deuterium-tritium reaction. An important part of the U.S. Fusion Energy Sciences Program is its participation in the International Thermonuclear Experimental Reactor (ITER) program. Taking into account the international situation and U.S. domestic issues, the ITER process is exploring reduced-cost options to the present ITER device. A Special Working Group, reporting to the ITER Council, has been formed to explore these issues on behalf of the ITER Parties, i.e., the European Union, Russian Federation, Japan, and the United States. This report and its related activities will aid the United States in the international process. This report is the result of a broad-based U.S. community effort to discuss, debate, and work together on the crucial issues involved in considering next-step options. The main content of this report is based on three potential pathways identified at a broadly attended community Forum for Next-Step Fusion Experiments (University of Wisconsin, Madison, April 1998) organized principally by the University Fusion Association and by the work of the ITER Steering Committee—US (ISCUS) on reduced cost ITER options. The Madison Workshop was followed by a smaller Workshop on Next-Step Options (University of California, San Diego, June 1998) to focus on preparing this report. A broadly-announced Website was established to facilitate access to documents related to this process.
