杀虫基因及其用途
摘要：
本发明涉及一种杀虫基因及其用途，所述杀虫基因的核苷酸序列包括：（a）具有SEQ ID NO:3所示的核苷酸序列；或（b）与（a）的核苷酸序列同类编码，且不为SEQ ID NO:22；或（c）在严格条件下与（a）或（b）限定的核苷酸序列杂交且编码具有杀虫活性的蛋白质的核苷酸序列。本发明杀虫基因特别适合在单子叶植物中表达，显著提高了Vip3Aa-01杀虫蛋白的表达量、稳定性和毒力；同时本发明通过植物体内产生能够杀死大螟的Vip3A蛋白来控制大螟害虫，对植物进行全生育期、全植株的保护以防治大螟害虫的侵害，且无污染、无残留，效果稳定、彻底，简单、方便、经济。
摘要（英）：

Involved is pesticidal gene and use thereof, the nucleotide sequence of the pesticidal gene comprises: (a) a nucleotide sequence as shown in SEQ ID NO: 3; or (b) a nucleotide sequence as shown in SEQ ID NO: 4; or (c) an isocoding sequence of (a) or (b) which is not the nucleotide sequence as shown in SEQ ID: 22 or SEQ ID NO: 26; or (d) a nucleotide sequence which hybridizes with the nucleotide sequence as shown in (a), (b) or (c) under stringency conditions and encodes a protein having pesticidal activity. The pesticidal gene of present application is particularly suitable for expression in monocotyledonae and notably increases the expression level, stability and virulence of pesticidal protein Vip3A. At the same time, in present application, Sesamia inferens is controlled by the Vip3A protein having pesticidal activity against Sesamia inferens, which is produced in the plants.
