From: Incomplete homogenization of 18 S ribosomal DNA coding regions in Arabidopsis thaliana
Polymorphism of Arabidopsis accessions for the presence of the deletion variant of 18S. Genomic DNA from four ecotypes was PCR amplified with primer pairs for the detection of (A) the internal control eIF4A (lanes and templates: M: Marker, 1: water, 2: Columbia, 3: Landsberg erecta, 4: Bay, 5: Shahdara) and (B) the deleted 18 S (lanes and templates: M: ladder, 1: water, 2: full length 18 S plasmid (negative control), 3: deleted 18 S plasmid (positive control) 4: Columbia, 5: Landsberg erecta, 6: Bay, 7: Shahdara). Arrows indicate 500 and 700 bp bands from ladder.
