Insulation protection related to protein variants of Cry1ca insecticides, polygons encoding these variants, hypoxic cells, plants transformed with this nucleic acid, and pest control methods.
a. Cry1Ca variant protein with insecticidal activity, because all or part of alpha 1, 2a and / or 2B propellants at amino end of wild protein Cry1Ca terminal are separated; polynucleotide separated from coding; microbial cell containing such polynucleotide; plant cell producing such polynucleotide; There are also ways to control lion insectsProteína variante Cry1Ca que tiene actividad insecticida, porque el total o parte de las hélices alfa 1, 2A y/o 2B del extremo amino terminal de una proteína Cry1Ca de tipo salvaje están delecionadas; polinucleótido aislado que la codifica; célula microbiana que comprende dicho polinucleótido; célula de planta que la produce; y método para controlar un insecto lepidóptero.
