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
