ADNA synthetic sequence having enhanced insecticidal activity in maize.

NAKED DNA SEQUENCES ARE optimized for expression in plants. THE STRINGS PREFERABLY DNA encoding the polypeptides Insecticide, PARTICULARLY insecticidal proteins from Bacillus thuringiensis. ALSO they ARE PROVIDED plant promoters, INCLUDING KNITTING AND PROMOTERS OF SPECIFIC TISSUE REFERRALS. IN ADDITION they are discovered transformation vectors comprising said DNA sequences. TRANSFORMATION VECTORS DEMONSTRATE INSECTICIDA high activity levels when transformed into maize.
