Cry29A and Cry30A: Two Novel [delta]-endotoxins Isolated from Bacillus thuringiensis serovar medellin

Two novel crystal protein genes from a highly mosquitocidal Bacillus thuringiensis serovar medellin strain were cloned and sequenced. The corresponding proteins, Cry29A and Cry30A, were nontoxic when tested individually against the mosquito species bioassayed (Aedes aegypti, Culex pipiens and Anophe...

Description
Summary:Two novel crystal protein genes from a highly mosquitocidal Bacillus thuringiensis serovar medellin strain were cloned and sequenced. The corresponding proteins, Cry29A and Cry30A, were nontoxic when tested individually against the mosquito species bioassayed (Aedes aegypti, Culex pipiens and Anopheles stephensi). However, Cry29A synergized the toxicity of Cry11Bb against Aedes aegypti by a four-fold factor.
