4 . effect of resolution vector on the expression of pesticidal crystal protein genes this work successfully introduced pesticidal crystal protein genes into crystal negative strain bmb171 by using resolution shuttle vectors . after resolution , the expression of cry1ac and cry 1c genes have no obvious change , but the expression of cry3a genes has great increase in the same condition 解离反应对杀虫晶体蛋白基因表达的影响成功地利用解离载体将crylac10 , crylc和cry3a基因导入苏云金芽胞杆菌无晶体突变株, crylac和crylc基因解离前后的表达量和杀虫毒力未见明显变化, cry3a基因在相同条件下则表达量有所提高,至于为何只对基因cry3a有作用尚不清楚,国内外也未见有人作相关报道。
