First Report of <i>Leptographium abietinum</i> Associated with Blue Stain on Declining Western Siberian Larch in Alaska

Fig. 2. Amplification product corresponding to Leptographium abietinum internal ribosomal spacer region. Agarose gel electrophoresis was conducted using a 1.5% agarose gel. Lane 1: molecular weight marker with bands from 12, 10, 8, 6, 4, 3, 2, 1.5, 1.0, and 0.5 kilobase pairs in length (top to bottom, respectively); Lanes 2 to 4: three distinct replicate amplification products of approximately 0.43 kilobase pairs in size derived using specific primers to the L. abietinum internal ribosomal spacer region and genomic DNA as template using polymerase chain reaction.
