A Brief History of Canola Genetic Gains: From Classical Breeding to Genome Editing

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Canola exemplifies the transformation of a crop from industrial use to a globally significant edible oilseed through sustained genetic and biotechnological innovation. Historically, rapeseed was characterized by high erucic acid and glucosinolate contents, restricting its use primarily to industrial applications.

Expression of recombinant and mosaic Cry1Ac receptors from Helicoverpa armigera and their influences on the cytotoxicity of activated Cry1Ac to Spodoptera litura Sl-HP cells [PDF]

Cytotechnology, 2014
Bacillus thuringiensis (Bt) toxin receptors play important roles in the killing of pests, and investigation on characterization of the receptors is essential for utilization of Bt and management of insect resistance. Here, recombinant and mosaic receptors of Bt Cry1Ac toxin from Helicoverpa armigera were expressed in Spodoptera litura Sl-HP cells and ...

Proteolytic stabilization of a spider venom peptide results in an orally active bioinsecticide

Pest Management Science, Volume 81, Issue 10, Page 6404-6415, October 2025.
Selective editing out of an insect gut protease cleavage site renders a spider‐derived insecticidal peptide active by ingestion by insect pests. Abstract BACKGROUND The toxin peptide U1‐AGTX‐Ta1b from the Hobo spider, Eratigena agrestis (Walckenaer, 1802), was studied to determine its potential to serve as a bioinsecticide.

Transgenic insect-resistant Bt cotton expressing Cry1Ac/1Ab does not harm the insect predator Geocoris pallidipennis

Ecotoxicology and Environmental Safety, 2022
The large-scale commercial cultivation of genetically modified (GM) cotton has brought significant economic and environmental benefits. However, GM crops must undergo strict environmental monitoring and long-term observation.

Proteomic Analysis of Bt cry1Ac Transgenic Oilseed Rape (Brassica napus L.)

Plants, 2023
Oilseed rape (Brassica napus L.) is an important cash crop, but transgenic oilseed rape has not been grown on a commercial scale in China. It is necessary to analyze the characteristics of transgenic oilseed rape before commercial cultivation. In our study, differential expression of total protein from the leaves in two transgenic lines of oilseed rape

Assessment of genetically modified soybean MON 94637 (application GMFF‐2023‐21116)

EFSA Journal, Volume 23, Issue 10, October 2025.
Abstract Genetically modified soybean MON 94637 was developed to provide protection against targeted lepidopteran pests. These properties were achieved by introducing the cry1A.2 and cry1B.2 expression cassettes. The molecular characterisation data and bioinformatic analyses do not identify issues requiring food/feed safety assessment.

Inheritance Patterns, Dominance and Cross-Resistance of Cry1Ab- and Cry1Ac-Selected Ostrinia furnacalis (Guenée)

Toxins, 2014
Two colonies of Asian corn borer, Ostrinia furnacalis (Guenée), artificially selected from a Bt-susceptible colony (ACB-BtS) for resistance to Cry1Ab (ACB-AbR) and Cry1Ac (ACB-AcR) toxins, were used to analyze inheritance patterns of resistance to Cry1 ...

Molecular mechanism of ATP‐binding cassette transporter‐mediated insecticide resistance

New Plant Protection, Volume 2, Issue 3, September 2025.
Advances in functional genomics (RNAi and CRISPR/Cas9) and artificial intelligence‐driven structure prediction (e.g., AlphaFold) are elucidating how ATP‐binding cassette transporters mediate insecticide resistance to both synthetic chemicals and Bacillus thuringiensis toxins.
