1Results are based on one Southern experiment - the number of copies is possibly higher.
2Truncated copies assumed after detection of multiple attE signals on HindIII digested DNA.
3Truncated copies assumed after detection of different numbers of nptII and attE signals on XbaI digested DNA.
6Non-transformed ‘Pinova’.
?: Results are ambiguous.
n.a.: not analysed.
