Overview of the transgenic plant lines used

In all transformants, the T-DNAs were inserted into one locus. ND, Not determined.

Transformant	T-DNA	No. of T-DNAsa	Configurationsb
PA23	Ksb	2	Read through
PA22	Ksb	4	IRRB, read through
PA25	Ksb	2	IRRB
PA29	Ksb	4–6	At least one IRRB
PA1	Ksb	4–6	At least one IRRB, read through
PA5	Ksb	4–6	IRRB, read through
PA16	Ksb	3–4	Read through
CRE13	Cre	ND	ND
HSC6	Cre	ND	ND

^aT-DNA copy number determined on the basis of the number of T-DNA/plant DNA junction fragments on the DNA gel blots.

^bRead through, vector backbone sequence inserted between two T-DNAs in tandem orientation, presumably because of read through at the LB.
