The cryIc gene from Bacillus thuringiensis provides protection against Spodoptera littoralis in young transgenic plants
A 3'-end truncated crystal protein gene derived from #Bacillus thuringiensis# subsp. #aizawai# 7.29, encoding the toxic fragment of the insecticidal CRYIC protein, was placed under the control of the CaMV 35S promoter with a duplicated enhancer. Its expression in tobacco conferred significant insecticidal activity towards the important pest #Spodoptera littoralis#. Expression of the CRYIC toxin is at its maximum level at the early stages of plant development then decreases as the plants become older.
