Mining novel Bacillus thuringiensis toxins and secondary metabolites for invasive fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae) control

Austral Entomology, Volume 64, Issue 1, February 2025.
Abstract Bacillus thuringiensis (Bt) endotoxins are often considered environmentally friendly pest control tools. However, the development of resistance to Bt toxins and emergence of exotic pests necessitate the characterisation of new Bt isolates. This study aims to identify and characterise novel Bt toxins and bioactive compounds that may be utilised

Early‐season floral bud loss has little impact on the maturity, yield, and lint quality of high‐yielding Bt cotton crops

Crop Science, Volume 65, Issue 1, January/February 2025.
Abstract Protecting floral buds (squares) from insect damage in cotton during early growth is a priority for crop managers despite unclear implications for yield potential and increased system risks from early‐season insecticide use. This study was conducted to determine the compensatory responses of high‐yielding Bacillus thuringiensis (Bt) cotton ...

Comparative Analysis of CrylAc Toxin Oligomerization and Pore Formation Between Bt-Susceptible and Bt-Resistant Helicoverpa armigera Larvae

Journal of Integrative Agriculture, 2012
With the long-term use of Bacillus thuringiensis (Bt) insecticide and expansion of Cry1A-expressing transgenic plants, some insect pests have developed resistance to Bt in open fields, greenhouses, and in the laboratory.

Lack of Cry1Fa binding to the midgut brush border membrane in a resistant colony of Plutella xylostella moths with a mutaton in the ABCC2 locus [PDF]

, 2012
Previous studies reported "mode 1" Bacillus thuringiensis resistance in a colony of diamondback moths (NO-QA), and recently, this resistance has been mapped to an ABC transporter (ABCC2) locus.

Genome mining of Bacillus thuringiensis strain SY49.1 reveals novel candidate pesticidal and bioactive compounds

Pest Management Science, Volume 81, Issue 1, Page 298-307, January 2025.
This study identified novel genes responsible for producing putative pesticidal toxins, antimicrobial compounds, and plant growth‐promoting proteins, shedding light on the potential agricultural applications of the Bt SY49.1 strain. Abstract BACKGROUND Bacillus thuringiensis SY49.1 (Bt SY49.1) strain has promising insecticidal and fungicidal activity ...

Expression profiling of key pathways in rat liver after a one-year feeding trial with transgenic maize MON810 [PDF]

, 2019
In a recent one-year feeding study, we observed no adverse effects on tissue level in organs of rats fed with the genetically-modified maize MON810. Here, we assessed RNA expression levels of 86 key genes of the apoptosis-, NF-кB-, DNA-damage response ...

Application of CRISPR Technology in Plant Improvement: An Update Review

Advances in Agriculture, Volume 2025, Issue 1, 2025.
Clustered regularly interspaced short palindromic repeats/CRISPR‐associated protein 9 (CRISPR/Cas9) stands as a major technique in genetic engineering, offering innumerable applications for enhancing agricultural and horticultural crops. It contributes significantly to improving quality traits, managing biotic and abiotic stresses, and extending shelf ...

Domain III of Cry1Ac Is Critical to Binding and Toxicity against Soybean Looper (Chrysodeixis includens) but Not to Velvetbean Caterpillar (Anticarsia gemmatalis)

Toxins, 2018
Insecticidal proteins Cry1Ac and Cry2Ac7 from the bacterium Bacillus thuringiensis (Bt) belong to the three-domain family of Bt toxins. Commercial transgenic soybean hybrids produce Cry1Ac to control the larvae of the soybean looper (Chrysodeixis ...

Maize yields have stagnated in sub‐Sahara Africa: a possible transgenic solution to weed, pathogen and insect constraints

Pest Management Science, Volume 80, Issue 9, Page 4156-4162, September 2024.
Single locus combinatorial biolistic transgenic engineering of genes encoding resistance to the multiple weed, insect and pathogen constraints bred into high‐yielding germplasm can overcome stagnating African maize yields. Abstract Despite major breeding efforts by various national and international agencies, yields for the ~40 million hectares of ...
