Interaction of Bacillus thuringiensis Cry1 and Vip3A proteins with Spodoptera frugiperda midgut binding sites
(2009-04-01)
Vip3Aa, Vip3Af, Cry1Ab, and Cry1Fa were tested for their toxicities and binding interactions. Vip3A proteins were more toxic than Cry1 proteins. Binding assays showed independent specific binding sites for Cry1 and Vip3A ...

Synergism of the Bacillus thuringiensis Cry1, Cry2, and Vip3 Proteins in Spodoptera frugiperda Control
(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) ...
Proteínas Cry1 e Vip3A de Bacillus thuringiensis: sinergismo e efeito sub-letal no controle de Heliothis virescens
(Universidade Estadual Paulista (Unesp), 2012-02-17)
A bactéria Bacillus thuringiensis (Bt) possui a capacidade de produzir inclusões protéicas (proteína Cry) e proteínas vegetativas (Vip). Estas proteínas podem ser tóxicas para insetos e por meio de transgenia, a expressão ...
Synergism and Antagonism between Bacillus thuringiensis Vip3A and Cry1 Proteins in Heliothis virescens, Diatraea saccharalis and Spodoptera frugiperda
(Public Library Science, 2014-10-02)
Second generation Bt crops (insect resistant crops carrying Bacillus thuringiensis genes) combine more than one gene that codes for insecticidal proteins in the same plant to provide better control of agricultural pests. ...
Cry1Ac and Vip3Aa proteins from Bacillus thuringiensis targeting Cry toxin resistance in Diatraea flavipennella and Elasmopalpus lignosellus from sugarcane
(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 ...
Interação de proteínas Vip3A e Cry1la10 de Bacillus thuringiensis com atividade inseticida a lepidópteros-praga
(Universidade Estadual Paulista (Unesp), 2015-02-06)
Vip3Aa and Cry1Ia proteins have potential in control of Lepidopteran pest and emerge as a promising alternative in the pest resistance management the Cry1A proteins, which has been highly used in the formulation of commercial ...
Seleção e caracterização de novos genes vip3A: genes inseticidas de segunda geração de Bacillus thuringiensis
(Universidade Estadual Paulista (Unesp), 2010-12-03)
Como uma alternativa para diminuir as agressões constantes que o ecossistema vem sofrendo, devido à grande quantidade de produtos químicos utilizados no controle de pragas, pesquisas envolvendo microrganismos capazes de ...
