Detecting Single Seeds of Small Broomrape (<i>Orobanche minor</i>) with a Polymerase Chain Reaction

Fig. 4. Approximate locations on Orobanche minor’s nuclear ribosomal DNA of the universal primers ITS5, ITS4, NS1, and NS2, and of the O. minor-specific primers OM1 and OM2. Nuclear ribosomal genes are in blue and internal transcribed spacer regions in white.
