    Agarose gel electrophoresis analysis of 3 combinant expression plasmid. The plasmid was confirmed by PCR and double digestion using <t>NcoI</t> and <t>XhoI.</t> Lane 1 was the fragment of recombinant plasmid DNA pTriEx-1.1 Hygro-β 2 -AR. Lane 2 was the electrophoresis results of digested products containing 2 fragments (6951 bp and 1257 bp). A 3300 bp fragment (lane 3 and lane 4) was amplified by PCR from the recombinant plasmid, which was identical with the sum of the size of target gene and vector sequences between NcoI and XhoI.

    Assessment of def1 Δ in Meiosis and Mitosis (A) Immunocytology of nuclear spreads of SK1 wild-type and def1Δ strains after 8 h of sporulation. The meiosis-specific subunit of cohesin, Rec8, was tagged with multiple Haemagglutinin (HA) epitopes. Using antibodies for HA and Zip1 allowed analysis of sister chormatid cohesion and synaptonemal complex formation, respectively. It can be seen in the wild-type example that all 16 chromosomes have long cohesin axes and close to full chromosome synapsis except for the rDNA region on Chromosome XII. Whereas from the first panel for def1Δ it can be seen that axes are aligned but synapsis is minimal. The second and third panels for def1Δ again show aligned axes, but homologues are only partially synapsed. However, as shown in the final panel, synapsis was observed in some meiotic nuclei of the def1Δ strain. Polycomplexes (PCs) of Zip1 were observed in 20% of the nuclei counted for def1Δ at this time point whereas less than 1% PCs were observed for the wild type. (B) Time course of the meiotic nuclei counted using immunocytology for both wild type and def1Δ during meiosis. The def1Δ mutant synapsis phenotype represented in (A) was counted as “aligned” axes in the Rec8 analysis graph. At least 200 nuclei were counted per time point. (C) Ectopic URA3 - ARG4 interval on Chromosome III described in Figure 3 . <t>XhoI</t> and EcoRI restriction sites are indicated by “X” and “E,” respectively. To detect NCOs, COs, and DSBs, <t>DNA</t> is digested with XhoI and EcoRI then probed with HIS4 sequences (hisU; [ 44 ]). For graphs (D–F), wild-type and def1Δ are represented by blue squares and pink diamonds, respectively. The corresponding XhoI and EcoRI double digest Southern blots, the XhoI single digest Southern blots, together with the molecular analyses, are presented in Figure S5 . (D) Molecular analysis for DSB (DSB2) signal/total lane signal from Southern blots of DNA extracted from synchronized meiotic cultures. (E) Molecular analysis for NCO (NCO1) signal/total lane signal from Southern blots of DNA extracted from synchronized meiotic cultures. (F) Molecular analysis for CO (CO1') signal/total lane signal from Southern blots of DNA extracted from synchronized meiotic cultures. (G) Southern blot of DNA isolated from wild-type and def1Δ SK1 strains containing the ectopic URA3 - ARG4 interval on Chromosome III. DNA was digested with XhoI and EcoRI then probed to detect NCOs, COs, and DSBs; mw represents the 1-kb molecular weight marker (Fermentas).

    Cloning of the Ad12 fiber knob and the extracellular domains of human CAR. (a) The Ad12 knob domain (line) begins at a conserved Thr-Leu-Trp-Thr motif (amino acids 409 to 412) and extends to the fiber protein carboxy terminus (Glu587). A fragment of Ad12 DNA encoding the entire knob domain and several amino acids from the preceding fiber shaft region (striped box) beginning at Ser401 was amplified by PCR using forward primer 1 and reverse primer 2. The resulting PCR product was cloned between the Nde I and Bam HI sites of pET15b. (b) The human CAR protein consists of an amino-terminal signal peptide (open box), two extracellular Ig-related domains <t>(D1</t> and D2), a membrane-spanning region (TM), and a cytoplasmic domain (CYT). cDNA fragments encoding D1 and D1/D2 were amplified by PCR using forward primer 3 and reverse primers 4 and 5. The resulting PCR products were cloned between the Nco I and <t>Xho</t> I sites of pET20b. Similar D1- and D1/D2-encoding cDNA fragments were amplified by PCR using forward primer 6 and reverse primers 7 and 8. The resulting PCR products were cloned between the Nde I and Bam HI sites of pET15b. (c) pET vectors for protein expression in E. coli . The open and filled boxes represent bacterial signal peptides and hexahistidine tags, respectively. The restriction sites used in this study are shown, and the sequence of the pET15b-encoded 22-amino-acid carboxy-terminal extension of sD1 is given in single-letter code.

    Assessment of def1 Δ in Meiosis and Mitosis (A) Immunocytology of nuclear spreads of SK1 wild-type and def1Δ strains after 8 h of sporulation. The meiosis-specific subunit of cohesin, Rec8, was tagged with multiple Haemagglutinin (HA) epitopes. Using antibodies for HA and Zip1 allowed analysis of sister chormatid cohesion and synaptonemal complex formation, respectively. It can be seen in the wild-type example that all 16 chromosomes have long cohesin axes and close to full chromosome synapsis except for the rDNA region on Chromosome XII. Whereas from the first panel for def1Δ it can be seen that axes are aligned but synapsis is minimal. The second and third panels for def1Δ again show aligned axes, but homologues are only partially synapsed. However, as shown in the final panel, synapsis was observed in some meiotic nuclei of the def1Δ strain. Polycomplexes (PCs) of Zip1 were observed in 20% of the nuclei counted for def1Δ at this time point whereas less than 1% PCs were observed for the wild type. (B) Time course of the meiotic nuclei counted using immunocytology for both wild type and def1Δ during meiosis. The def1Δ mutant synapsis phenotype represented in (A) was counted as “aligned” axes in the Rec8 analysis graph. At least 200 nuclei were counted per time point. (C) Ectopic URA3 - ARG4 interval on Chromosome III described in Figure 3 . XhoI and EcoRI restriction sites are indicated by “X” and “E,” respectively. To detect NCOs, COs, and DSBs, DNA is digested with XhoI and EcoRI then probed with HIS4 sequences (hisU; [ 44 ]). For graphs (D–F), wild-type and def1Δ are represented by blue squares and pink diamonds, respectively. The corresponding XhoI and EcoRI double digest Southern blots, the XhoI single digest Southern blots, together with the molecular analyses, are presented in Figure S5 .

(a) The Ad12 knob domain (line) begins at a conserved Thr-Leu-Trp-Thr motif (amino acids 409 to 412) and extends to the fiber protein carboxy terminus (Glu587). A fragment of Ad12 DNA encoding the entire knob domain and several amino acids from the preceding fiber shaft region (striped box) beginning at Ser401 was amplified by PCR using forward primer 1 and reverse primer 2. The resulting PCR product was cloned between the Nde I and Bam HI sites of pET15b. (b) The human CAR protein consists of an amino-terminal signal peptide (open box), two extracellular Ig-related domains (D1 and D2), a membrane-spanning region (TM), and a cytoplasmic domain (CYT). cDNA fragments encoding D1 and D1/D2 were amplified by PCR using forward primer 3 and reverse primers 4 and 5.
