Protein-based pesticides could target pests without harming other insects

Crop Improvement
The bees and ladybugs working your garden could survive future pest control efforts if these precision peptides replace the broad-spectrum sprays that kill indiscriminately.
Researchers are studying tiny protein chains called peptides that can kill crop-damaging insects while leaving other creatures alone. Unlike many chemical pesticides that harm bees, worms, and other helpful garden life, these peptides break down naturally and can be designed to target just the pests causing trouble. The team is even using artificial intelligence to help design better versions and package them in tiny delivery capsules so they work longer in the field.
Key Findings
Insecticidal peptides work through multiple mechanisms including pore-forming action, enzyme inhibition, and mimicking insect neuroendocrine hormones
AI-guided engineering is being explored to design more selective and effective peptide structures
Nanodelivery systems are proposed to enable controlled release, improving field performance and reducing environmental persistence
chevron_right Technical Summary
Scientists are engineering peptides, naturally occurring protein fragments, into targeted pest-killers that could replace broad-spectrum chemical pesticides. These peptides can be tuned to attack specific insects while breaking down harmlessly in the environment, potentially protecting crops with less collateral damage to beneficial bugs and ecosystems.

Gene editing removes 97% of celiac-triggering proteins from bread wheat
It could mean that people with celiac disease — roughly 1 in 100 worldwide — may one day safely eat bread made from real wheat, without sacrificing the taste...
Climate adaptation in plants refers to the physiological and evolutionary mechanisms through which plants adjust to changing environmental conditions, including temperature shifts, altered precipitation patterns, and seasonal variations. Understanding these processes is essential for plant science
