一种抗虫蛋白Cry1A.401、其表达载体及应用
摘要：
本发明提供了一种抗虫蛋白Cry1A.401，其特征在于，其具有：1)由SEQ ID No.2所示的氨基酸序列；或2)SEQ ID No.2所示的氨基酸序列经取代、缺失和/或增加一个或多个氨基酸且具有同等功能的氨基酸序列。体外实验证明改造合成的Bt基因产毒蛋白对玉米螟有显著的杀虫效果，本发明的抗虫基因Cry1A.401能够在单子叶植物中稳定高效表达，进而用于生产抗虫转基因植物。
摘要（英）：

The invention provides an anti-insect protein Cry1A.401, which is characterized by comprising: (1) an amino acid sequence shown as SEQ ID No.2, or (2) an amino acid sequence which is obtained by performing substitution, deletion and/or addition of one or more amino acids on the amino acid sequence shown as SEQ ID No.2 and has equal function. As proved by an in-vitro experiment, a modified and synthesized Bt gene toxoggenic protein has a remarkable insecticidal effect on corn borers. The anti-insect protein Cry1A.401 can be stably and efficiently expressed in monocotyledons, and is further applied to production of anti-insect transgenic plants.
