While highly effective and precise, transgenic approaches face considerable regulatory and public acceptance barriers, particularly in regions with strict GMO legislation. The advent of CRISPR/Cas genome editing has revolutionized plant breeding by enabling precise, efficient, and targeted modification of native genes, significantly accelerating the development of improved crops.
