Field performance of MON 94637 and laboratory evidence supporting a Bt pyramiding strategy against key lepidopteran pests in Brazil

Pest Management Science, EarlyView.
A genetically modified soybean expressing multiple Cry proteins protects against key lepidopteran pests, consistently reducing larval damage and offering an effective resistance management option for soybean production in Brazil. Abstract BACKGROUND Pyramided Bt genes in crops have been widely adopted to delay insect resistance evolution worldwide. The

Adaptation of Bacillus thuringiensis to Plant Colonization Affects Differentiation and Toxicity

mSystems, 2021
The Bacillus cereus group (Bacillus cereus sensu lato) has a diverse ecology, including various species that are vertebrate or invertebrate pathogens. Few isolates from the B. cereus group have however been demonstrated to benefit plant growth. Therefore,

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Diversity of the Microbiomes in the Larval and Adult Stages of the European Cherry Fruit Fly (Rhagoletis cerasi) and Identification of Potential Biocontrol Candidate Taxa

Entomologia Experimentalis et Applicata, EarlyView.
First comprehensive characterization of the R. cerasi microbiome is reported. Stage‐specific variations in microbial composition are documented. Multiple bacterial entomopathogen taxa are identified as potential biocontrol candidates for R. cerasi.

Isolation and characterization of bacteria from two soil samples and their effect on wheat (Triticum aestivum L.) growth promotion

Journal of Advanced Biotechnology and Experimental Therapeutics, 2020
Since ancient times, soil bacteria play an important role on crop growth and yield by genetic transformation naturally. But the continuous use of chemical fertilizers reduces their number and proper environment for multiplication.

Transformation ofBacillus thuringiensisby electroporation [PDF]

FEMS Microbiology Letters, 1989
Plasmids were transformed by electroporation into various strains of Bacillus thuringiensis with frequencies of up to 10(5) transformants/micrograms. pC 194 transformed all strains tested at a high frequency and cells could be stably transformed with pC194 and pUB110 simultaneously by electroporation with a frequency of 10(2) pC194+ pUB110 ...

Exploiting Native Biodiversity for Invasive Species Management: The Case of Exorista larvarum as a Natural Enemy of the Invasive Box Tree Moth Cydalima perspectalis

Entomologia Experimentalis et Applicata, EarlyView.
The investigations evaluated the performance of the native parasitoid Exorista larvarum (L.) on last instar Cydalima perspectalis (Walker) larvae, using the factitious host Galleria mellonella (L.) as a control. Laboratory bioassays were conducted using no‐choice and choice (1:1 and 5:5) experimental designs.

Completed Genomic Sequence of Bacillus thuringiensis HER1410 Reveals a Cry-Containing Chromosome, Two Megaplasmids, and an Integrative Plasmidial Prophage

G3: Genes, Genomes, Genetics, 2020
Bacillus thuringiensis is the most used biopesticide in agriculture. Its entomopathogenic capacity stems from the possession of plasmid-borne insecticidal crystal genes (cry), traditionally used as discriminant taxonomic feature for that species. As such,
