    Notes: 2 /C2H2 ratio for diamond synthesis in oxyacetylene flames can be theoretically predicted. When the substrate temperature is between 1000 K and 1250 K, the corresponding O2/C2H2 ratio range is about between 0.8 and 1.1. The suitable range of substrate temperature is widest for O2/C2H2 ratio close to unity and is narrowed rapidly when the flow ratio deviates from unity.

    Notes: Abstract A size-fractionated TaqI genomic library of seashore paspalum (Paspalum vaginatum Swartz) was screened for the presence of (GA) n and (CA) n simple sequence repeats (SSRs). A total of 54 clones with a positive signal were detected among 13,000 clones screened. Forty-seven clones having repeats of n⩾ 3 were identified, of which 85% were perfect, 13% were imperfect and 2% were compound repeat sequences. Five of ten primer pairs synthesized to amplify selected loci resulted in a product in the expected size range and were subsequently used to examine SSR polymorphisms among 46 ecotypes of P. vaginatum. The number of alleles resolved on agarose or polyacrylamide gels were similar and ranged from 6 to 16 with an average of 14 per locus. Phenetic analysis of SSR polymorphisms revealed genetic relationships among the P. vaginatum ecotypes that were in general agreement with relationships determined previously by RAPD analysis of the same plant materials. Further screening of the genomic library did not identify (AT) n , trimeric or tetrameric repeats. Hybridization of an (ATT)8 oligonucleotide probe to genomic DNA isolated from I. batatas, E. coli, Citrullis lanatus and P. vaginatum suggested that the P. vaginatum genome contained significantly fewer ATT repeats than either the I. batatas or C. lanatus genome.

    Notes: Abstract Simple sequence repeats (SSRs), or microsatellites, are a new class of PCR-based DNA markers for genetic mapping. The objectives of the present study were to develop SSR markers for barley and to integrate them into an existing barley linkage map. DNA sequences containing SSRs were isolated from a barley genomic library and from public databases. It is estimated that the barley genome contains one (GA)n repeat every 330 kb and one (CA)n repeat every 620 kb. A total of 45 SSRs were identified and mapped to seven barley chromosomes using doubled-haploid lines and/or wheat-barley addition-line assays. Segregation analysis for 39 of these SSRs identified 40 loci. These 40 markers were placed on a barley linkage map with respect to 160 restriction fragment length polymorphism (RFLP) and other markers. The results of this study demonstrate the value of SSRs as markers in genetic studies and breeding research in barley.
