The results indicated that the c-terminal fragment of Arabidopsis CRY1 gene was successfully integrated into the rape genome, mainly in the form of tabling, with a few in the form of single copy. The transformed gene could be stablytransmitted in the progeny, with a transmitted line rate of 62.5%. The genetic pattern of the transformed gene in the T_2 generation was mostly non-Mendelian. The transgene was expressed in some of the transgenic plants, but kept silent, in other plants.
