This one's about pigs and cattle, not your garden, but the same CRISPR toolkit behind these livestock edits is already being used to engineer disease resistance and better traits into crops you might grow.
This article is about editing the genes of farm animals like pigs, not plants. Scientists use tools such as CRISPR to make precise changes to animal DNA, creating pigs that could one day donate organs to humans or resist diseases, and improving livestock for food production. There's no new plant science here, but it's a useful look at how far gene-editing technology has come across living things in general.
Key Findings
Programmable nucleases (ZFNs, TALENs, CRISPR-Cas) have overcome historic barriers in livestock genetic engineering, including the lack of embryonic stem cells and low efficiency of homologous recombination
Pigs are highlighted as the leading livestock model for xenotransplantation, disease modeling, and agricultural trait improvement
Remaining challenges include mosaicism, off-target effects, difficulty segregating unintended edits, and unresolved ethical/regulatory questions for food and biomedical uses
chevron_right Technical Summary
Scientists now use precision gene-editing tools like CRISPR to engineer pigs and other livestock for disease resistance, organ transplants into humans, and better farm traits, overcoming old breeding limitations that used to take generations to work around.

CRISPR is a gene-editing technology derived from bacterial immune systems that enables scientists to precisely modify DNA sequences in living organisms. In plant research, CRISPR has become transformative for developing crops with enhanced traits including disease resistance, improved yields, and
