    <p>Identification of the four proteins indicated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152273#pone.0152273.g001" target="_blank">Fig 1</a> from the conidia of Foc.</p

    <p>A: Foc-ΔSIX1 mutants were complemented by transformation with approximately 3.0 kb of <i>Foc-SIX1</i> spanning from -1838 bp (promoter relative to start codon) to 1132 bp (ORF and 3’ UTR). B: The <i>SIX1</i> gene, <i>hph</i> gene and <i>Neo</i> gene fragments were amplified by PCR to confirm the correct complementation mutants. C: Disease symptoms of cabbage seedlings inoculated with wild type isolate Foc, deletion mutants Foc-ΔSIX1, and complementation mutants Foc-ΔSIX1::Foc-SIX1 were shown at 14 dpi. Similar results were obtained in three independent biological replicates.</p

    Construction and verification of deletion mutants Foc-ΔSIX1.

    <p>A: <i>Foc-SIX1</i> gene deletion and replacement with an intact selectable marker gene (<i>hph</i>) by homologous recombination. B: Confirmation of the correct deletion by PCR. Numbers 1, 2, 3 and 4 represent the four primer pairs that specify the <i>SIX1</i> gene, <i>hph</i> gene, and the correct upstream and downstream homologous recombination, respectively. C: Southern hybridization analysis of wild type isolate and mutants Foc-ΔSIX1. The genomic DNAs from the wild type Foc isolate and deletion mutants Foc-ΔSIX1 were digested with <i>Sal</i> I. A fragment amplified from upstream of the target gene was used as probe.</p

    <p>Proteins were separated by using 24 cm, pH 4–7 IPG strips for IEF and followed by 12.5% SDS-PAGE. The gels were stained by GAP method, which used CBB-G250, ammonium sulfate, and phosphoric acid. A: Gel of conidia proteins from Foc grown in PDB. B: The four proteins (spots 1, 2, 3 and 4), named Foc-SIX1 with high abundance in Foc, were indicated by arrows and numbers and listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0152273#pone.0152273.t001" target="_blank">Table 1</a>; Figure B is the partial enlarged details of the rectangular box in Figure A.</p
