Genetic Engineering of Insect Resistance

Insect pests threaten global food security, causing substantial yield losses and economic burdens. Traditional pest control methods, such as chemical insecticides, often come with adverse environmental consequences and limitations. However, genetic engineering offers a promising alternative by allowing scientists to introduce specific genes into crop plants, enabling them to repel or resist insect pests.

Lifeasible offers promising solutions to agricultural pest challenges by genetically engineering insect-resistant plants that are non-toxic to mammals and some beneficial insects and do not cause environmental pollution.

Two main types of genes have been discovered and applied to improve insect resistance in plants

• Insect resistance genes isolated from bacteria, such as Bacillus thuringiensis toxin gene (Bt) and isopentenyl transferases gene (ipt).
• Insect resistance genes isolated from plants, such as proteinase inhibitor (PI) genes, amylase inhibitor genes, exogenous lectin genes, etc.

Application of genetic engineering of insect resistance

Plants can create harmful or repulsive proteins to specific pests by integrating genes from naturally insect-resistant species, such as bacteria. The introduction of Bacillus thuringiensis (Bt) genes into crops is one well-known example. Bt proteins have been effectively incorporated into various crops, including corn, cotton, and soybeans. They are quite efficient against insect pests.

Importance of genetic engineering of insect resistance

By reducing the side effects caused by broad-spectrum conventional pesticides, genetic engineering of insect resistance offers a focused pest management method. This accuracy fosters ecosystem stability by lowering environmental pollution and preserving beneficial insect populations. Additionally, using genetically modified (GM) crops with insect resistance minimizes agricultural losses brought on by pests, increasing food production and enhancing farmer livelihoods.

What do we offer?

Genetic engineering of insect resistance employs several techniques to introduce insecticidal genes into crop plants. The primary method involves recombinant DNA technology, where specific insecticidal genes, such as those from Bt bacteria, are isolated and inserted into the plant genome. This process involves identifying and characterizing the target gene, cloning it into a suitable vector, and transferring it into plant cells using various transformation methods. These include Agrobacterium-mediated transformation and biolistic particle bombardment. Once integrated into the plant's DNA, the foreign gene is expressed, producing insecticidal proteins that confer resistance to targeted pests.

Besides, we are committed to exploring novel strategies, such as RNA interference (RNAi), to target specific insect genes and disrupt their vital functions. Additionally, advancements in genome editing technologies, such as CRISPR-Cas9, offer guidance for precise and site-specific modifications, enabling more tailored insect resistance traits.
