The low expression level of cry genes seems to be due to the presence in them of sequences not commonly found in plant coding regions. Such as

(1) Localized A+T-rich regions resembling plant intrans 

(2) 18 potential plant polyadenylation signal sequences 

(3) 13 ATTTA sequences, which destabilize mRNA

(4) Codons that are rarely used in plants
