    Article Snippet: Restriction analysis of the amplified 16S-rDNA fragment was done with the restriction enzymes Mse I and Bfa I (New England Biolabs) for 2 h at 37°C.

    Techniques:

    Agarose gel electrophoresis profiles of NtMLO alleles detected using the cleaved amplified polymorphic sequence (CAPS) method. Amplified DNA fragments were digested by Bci T130I or Bfa I for NtMLO1 , and Bse RI for NtMLO2 . Bci T130I and Bfa I digests the wild-type (susceptible) and mutant (resistant) NtMLO1 fragments, respectively, and Bse RI digests mutant (resistant) NtMLO2 fragments. In the heterozygotes, three (digested and undigested) DNA fragments are generated by the restriction enzyme treatment. 1: ‘Tsukuba 1’ (resistant); 2: ‘K326’ (susceptible); 3: F 1 hybrid of ‘Tsukuba 1’ × ‘K326’ (susceptible); 4: ‘Kokubu’ (resistant); 5: ‘Ibusuki’ (susceptible); 6: F 1 hybrid of ‘Kokubu’ × ‘Ibusuki’ (susceptible).

    Article Snippet: The following enzymes were selected for the digestion of the DNA: Bfa I (New England Biolabs) or Bci T130I (Takara) for NtMLO1 fragment digestion; Bse RI (New England Biolabs) for NtMLO2 fragment digestion.

    Alignment of NtMLO genomic DNA sequences and restriction enzyme recognition sites used in the cleaved amplified polymorphic sequence (CAPS) method. The NtMLO1 gene of powdery mildew-resistant cultivars harbors two-base transitions (AG to TA) at the 3ʹ end of intron 7. In the NtMLO2 gene, the fourth and fifth nucleotide (AG) of intron 6 are deleted in powdery mildew-resistant cultivars. The CAPS method detects these polymorphisms by restriction enzyme digestion patterns. Bci T130I and Bfa I recognize and digest the wild-type (powdery mildew-susceptible) and mutant (powdery mildew-resistant) NtMLO1 genomic DNA sequence, respectively. Bse RI recognizes and digests the mutant (powdery mildew-resistant) NtMLO2 genomic DNA sequence. Intron sequences are shown in bold letters. Arrow heads indicate the digestion site of each enzyme.

    Mutation analysis in two families with hereditary lymphedema. Mutations in the FOXC2 gene were detected by direct sequencing of the PCR-amplified coding region of the gene. Results were confirmed by sequencing the reverse strand and by restriction-enzyme analysis. a, Sequencing revealed a TAC→TAG nonsense mutation (C297G) ( arrow, left panel ) in the proband (II-7) in family 1, creating a novel Bfa I restriction site. The right panel shows the cosegregation of the novel restriction site with the LD phenotype. Fetus II-6 was also shown to have the mutation, by restriction digest analysis (not shown). A 439-bp region of the FOXC2 gene was PCR amplified and digested with Bfa I. Products from normal alleles are not cut and remain 439 bp, whereas the mutant allele is cut into 383- and 53-bp fragments (not retained on gel). b, Sequence analysis revealing a 4-bp insertion in the proband (IV-2) in family 2. The GGCC insertion creates a shifted sequence beginning at the arrow ( left panel ). A novel Nae I restriction site is created by the insertion. The right panel shows the cosegregation of the Nae I fragments with the LD phenotype in family 2. PCR was used to amplify a 125-bp region of the FOXC2 gene (129 bp for the mutant allele). Nae I digestion of the PCR products results in 35- and 90-bp fragments for normal alleles, because of the presence of a naturally occurring Nae I site in the product. In alleles with the insertion, the 129-bp product is cut twice, generating two 35-bp fragments and a 59-bp fragment. Bands labeled “HD” show uncut heteroduplexes.

    Article Snippet: Then, 200 ng (2 µL) of annealed ssODNs was digested with either Bfa I or PvuII-HF (1 U, New England Biolabs) in CutSmart buffer (1×) in a total volume of 10 µL and incubated at 37 °C for 1 h. Immediately after digestion, reactions were separated on an agarose gel (1.5%) stained with SYBR Safe (1×), imaged (UVP BioDoc-It) and analysed semi-quantitatively by gel densitometry using ImageJ (Supplementary Data ).
