Immunolocalization of HgSNARE-like protein-1 (HgSLP-1).

<p>Panels A—D are 40 x light field images matched with corresponding epiflorescent images of sections of SCN in soybean roots stained using HgSLP-1 antibodies. Arrows point to the basal cell of a subventral esophageal gland in A, the median bulb and esophageal lumen in B and the stylet in C. Panel D shows negative control sections lacking HgSLP-1 antibody staining in the nematode. Arrows in D point to the basal cell of an esophageal gland and the stylet. Panel D is a composite of two sequential sections from the same nematode. For all light field images, 20 micron scale bars are shown.</p

SCN genetic linkage groups containing SCN SNPs linked to virulence.

<p>The left column has the map distance in centimorgans and the right column shows the SNP number. The SCN SNPs that show an allelic imbalance when grown on resistant and susceptible soybean plants are shown in red.</p

Large read mapping of TN10 cDNA sequences to the HgSLP-1 genomic sequence.

<p>The Y-axis shows depth of mapped cDNA coverage (99% identical with 99%overlap of each read) and the X-axis indicates the base position along the <i>HgSLP-1</i> gene. The numbers mark the exons of <i>HgSLP-1</i>.</p

Protein gel blot of HgSNARE-like protein (HgSLP-1) and soybean α-SNAP protein expressed in <i>E</i>. <i>coli</i>. Proteins in lanes 1–5 were detected using an antibody that binds to HgSLP-1.

<p>Proteins in lanes 6–9 were detected using an antibody that binds to soybean α-SNAP. Lanes 1 and 6 contain purified protein from <i>E</i>. <i>coli</i> co-expressing full size HgSLP-1 and soybean α-SNAP. Lane 2, 3, 7, and 8 contain independent replicates of proteins purified from <i>E</i>. <i>coli</i> co-expressing HgSLP-1 missing its signal peptide and soybean α-SNAP. Lanes 4 and 9 contain purified protein from <i>E</i>. <i>coli</i> that only expresses full sized HgSLP-1. Lane 5 contains total protein from <i>E</i>. <i>coli</i> that only expresses full sized HgSLP-1. Protein sizes are shown in kDa.</p
