* cycling parameters had to be adjusted to the unusual amplicon size.
a) use of these primers resulted in a 380 bp amplicon in control lines, and
an additional 180 bp product in transgenic lines (no intron).
b) This amplicon was the result of the second set of primers in a nested
PCR; the size of the first product was 753 bp.
§ DNA was extracted from the soil (degraded plant material, or
microorganisms).
