 +
 +Genes //MusaPUB22// and //MusaPUB23// were identified through prior comparative transcriptomics analysis, which revealed their upregulation in susceptible versus resistant genotypes during early infection with //Xvm//. Several gene edited lines displayed complete resistance to //Xvm// infection, while others showed partial resistance, in contrast to the full susceptibility of wild-type controls. Resistance correlated with hydrogen peroxide accumulation and activation of key defense-related genes, indicating enhanced immune responses (Tripathi //et al//., 2025).
