The full length cDNA encoding CHS isolated from a torenia cv. ‘sum-merwave’ and fused with E12Vpromoter in
sense (pBETC6) or antisense (pBETC7) orienta-tion, was inserted into a binary vector plasmid
pBinl9 . A fragment of cDNA en-coding DFR (about 1.1 kb; lacking 5% side of the
coding region, AB012924), isolated from the ‘sum-merwave’ and fused with E12Vpromoter in sense
(pBETD10) or antisense (pBETD11) orientation,
was also inserted into binary vector plasmid
pBinl9
