Breakthroughs in Gene Editing for Peanut Biotechnology

Emerging technologies in gene editing are set to revolutionize the field of peanut biotechnology by enabling precise and multiplex genome editing to improve traits such as disease resistance, allergen reduction, seed quality, and yield. Traditional tissue culture-dependent methods have been hindered by lengthy protocols, genotype dependency, and somaclonal variation. However, CRISPR/Cas technologies have offered a solution by enabling rapid, cost-effective gene transfer, variable transformation efficiencies, and chimerism remain challenges, but new methods such as nanoparticle-based delivery, viral vectors, pollen magnetofection, pollen tube injection, node injection, and vacuum infiltration are being explored.
