Scientists Discover One-Step Genome Editing Technique that Accelerates Seed Breeding
A group of researchers have discovered a genome editing technique called
haploid induction editing (HI-EditT) technology, which ultimately reduces
the time it takes to develop commercial crop varieties.
HI-Edit refers to the reproductive process of haploid induction (HI), which
occurs naturally in wheat, corn, barley, and tobacco, combined with a genome
editing technology such as CRISPR-Cas9. Using HI-Edit, breeders can modify
crops at different stages in the seeds research and development process
without the substantial cost and time associated with introgression, which
takes up to seven years to fully complete.
While this research focused on field corn and sweet corn crops, there is
evidence that the technique could also be applied to wheat. The researchers
are also working on similar methods for the genus of plants related to
cabbage, broccoli, cauliflower, and kale that could eventually lead to
breakthroughs in soybeans and tomatoes.
