Baker Ds Cre-lox

Transformed with T-DNA lox-Dslox comprised of: CaMV 35S - lox (pairs of lox sites recombine site-specifically in presence of Cre transposase) - surA,B (chlorsulfuron resistance) interrupted by a Ds element, so that the existing line is chlorsulfuron susceptible. The Ds element contains CaMV 35S - bar (PptR gene, conferring phosphonothricin resistance), a lox site adjacent to a promoterless AAC (encoding gentamycin-3-N-acetyltransferase, conferring gentamycin resistance). The Dslox construct is in R orientation; supF from yeast; Nos-NptII (KanR gene conferring kanamycin resistance). Combined phosphonothricin, chlorsulfuron selection after crosses to Ac line (N8110) confirms transposition events. Gentamycin selection after crosses to Cre line (N8111) confirms lox-lox recombination with potential chromosomal rearrangements.
