Nucleic acid molecules encodng a cathepsin L-like cysteine protease
摘要：
Compositions and methods for protecting a plant from an insect pest are provided. In particular, nucleic acid sequences encoding insect protoxins modified to comprise at least one proteolytic activation site that is sensitive to a plant protease or an insect gut protease are provided. Cleavage of the modified protoxin at the proteolytic activation site by a protease produces an active insect toxin. Methods of using the modified insect protoxin nucleic acid sequences and the polypeptides they encode to protect a plant from an insect pest are provided. Particular embodiments of the invention further provide modified insect protoxin compositions and formulations, expression cassettes, and transformed plants, plant cells, and seeds.
摘要（中）：

提供了保护植物免受害虫害虫的组合物和方法。 特别地，提供了编码昆虫原毒素的核酸序列，其被修饰为包含对植物蛋白酶或昆虫肠道蛋白酶敏感的至少一个蛋白水解活化位点。 通过蛋白酶在蛋白水解活化位点切割修饰的原毒素会产生活性昆虫毒素。 提供了使用修饰的昆虫原毒素核酸序列及其编码的多肽保护植物免受害虫的方法。 本发明的具体实施方案还提供了改良的昆虫原毒素组合物和制剂，表达盒，以及转化的植物，植物细胞和种子。
