Plant disease resistance remains a cornerstone of global food security and sustainable agriculture. With the continuous emergence of new pathogen strains, integrating traditional breeding with molecular biology tools has opened novel avenues for enhancing crop resilience. This short communication highlights recent progress in understanding plant immune mechanisms and the translational potential of emerging biotechnologies, including CRISPR-Cas9 and RNA interference, in engineering durable resistance.
