• Bacillus thuringiensis toxins: an overview of their biocidal activity 

      Palma Dovis, Leopoldo Upna; Muñoz, Delia Upna; Berry, Colin; Murillo Martínez, Jesús Upna; Caballero Murillo, Primitivo Upna (MDPI, 2014)   Artículo / Artikulua  OpenAccess
      Bacillus thuringiensis (Bt) is a Gram positive, spore-forming bacterium that synthesizes parasporal crystalline inclusions containing Cry and Cyt proteins, some of which are toxic against a wide range of insect orders, ...
    • Draft genome sequences of two bacillus thuringiensis strains and characterization of a putative 41.9-kDa insecticidal toxin 

      Palma Dovis, Leopoldo Upna; Muñoz, Delia Upna; Berry, Colin; Murillo Martínez, Jesús Upna; Caballero Murillo, Primitivo Upna (MDPI, 2014)   Artículo / Artikulua  OpenAccess
      In this work, we report the genome sequencing of two Bacillus thuringiensis strains using Illumina next-generation sequencing technology (NGS). Strain Hu4-2, toxic to many lepidopteran pest species and to some mosquitoes, ...
    • Molecular and insecticidal characterization of a novel cry-related protein from bacillus thuringiensis toxic against Myzus persicae 

      Palma Dovis, Leopoldo Upna; Muñoz Labiano, Delia; Berry, Colin; Murillo Martínez, Jesús Upna; Escudero, Iñigo de; Caballero Murillo, Primitivo Upna (MDPI, 2014)   Artículo / Artikulua  OpenAccess
      This study describes the insecticidal activity of a novel Bacillus thuringiensis Cry-related protein with a deduced 799 amino acid sequence (~89 kDa) and ~19% pairwise identity to the 95-kDa-aphidicidal protein (sequence ...
    • The Vip3Ag4 insecticidal protoxin from bacillus thuringiensis adopts a tetrameric configuration that is maintained on proteolysis 

      Palma Dovis, Leopoldo Upna; Scott, David J.; Harris, Gemma; Din, Salah-Ud; Williams, Thomas L.; Roberts, Oliver J.; Young, Mark T.; Caballero Murillo, Primitivo Upna; Berry, Colin (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      The Vip3 proteins produced during vegetative growth by strains of the bacterium Bacillus thuringiensis show insecticidal activity against lepidopteran insects with a mechanism of action that may involve pore formation and ...
    • Vip3C, a novel class of vegetative insecticidal proteins from Bacillus thuringiensis 

      Palma Dovis, Leopoldo Upna; Hernández Rodríguez, Carmen Sara; Maeztu Martínez, Mireya; Hernández Martínez, Patricia; Ruiz de Escudero Fuentemilla, Íñigo; Escriche, Baltasar; Muñoz, Delia Upna; Rie, Jeroen van; Ferré, Juan; Caballero Murillo, Primitivo Upna (American Society for Microbiology, 2012)   Artículo / Artikulua  OpenAccess
      Three vip3 genes were identified in two Bacillus thuringiensis Spanish collections. Sequence analysis revealed a novel Vip3 protein class (Vip3C). Preliminary bioassays of larvae from 10 different lepidopteran species ...
