Odorant Receptor Gene in Codling Moth Also Affects Egg Production

A funny thing happened on the way to testing the CpomOR1 odorant receptor. Researchers at the USDA-Agricultural Research Service conducted an experiment on codling moth (Cydia pomonella) using the CRISPR/Cas9 gene-editing method to study the role played by a specific gene known as CpomOR1. The gene is highly expressed, or “switched on,” in the antennae […]

Mutational Chain Reaction Can Spread Throughout Insect Populations

By David O’Brochta A report recently published in Science describes a system by which one can introduce mutations into insect genomes and have those mutations quickly spread to all of the mutant’s progeny, and to all of their progeny’s progeny, and so on.The new system does not follow the standard rules of chromosome and gene […]
