Bacillus thuringiensis Cry1Ab Domain III β-16 Is Involved in Binding to Prohibitin, Which Correlates with Toxicity against Helicoverpa armigera (Lepidoptera: Noctuidae)

Universidade Estadual Paulista (Unesp); Universidad Nacional Autónoma de Mexico; Chinese Academy of Agricultural Sciences (2021-01-04)

Helicoverpa armigera is a major insect pest of several crops worldwide. This insect is susceptible to some Bacillus thuringiensis (Bt) Cry insecticidal proteins expressed in transgenic crops or used in biopesticides. ...

Cry1Ac and Vip3Aa proteins from Bacillus thuringiensis targeting Cry toxin resistance in Diatraea flavipennella and Elasmopalpus lignosellus from sugarcane

Universidade Estadual Paulista (Unesp); Universidade Federal Rural de Pernambuco (2017-01-01)

The biological potential of Vip and Cry proteins from Bacillus is well known and widely established. Thus, it is important to look for new genes showing different modes of action, selecting those with differentiated ...

Universidade Estadual Paulista (Unesp) (2019-07-15)

The polyphagous caterpillar, Spodoptera frugiperda, has been controlled with either chemical insecticides or transgenic plants such as Bt maize that expresses the cry and/or vip genes of the Bacillus thuringiensis (Bt) ...

Diversity and distribution of lepidoptera-specific toxin genes in Bacillus thuringiensis strains from Argentina

Sauka, Diego Hernan; Benintende, Graciela Beatriz (2017-05)

A total of 268 Bacillus thuringiensis strains obtained from different sources of Argentina were analyzed to determine the diversity and distribution of the cry1, cry2, cry8, cry9 and vip3A genes encoding for lepidopteran-specific ...
