-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).+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//.

 +Comparative transcriptomic analyses revealed a five-fold upregulation of //MusaVicilin// gene in //M. balbisiana// (BB genome) compared to the BXW- susceptible 'Pisang Awak' at early infection stage with the pathogen. //MusaVicilin// overexpression showed moderate correlation with disease resistance, with transgenic line (S2) demonstrating complete resistance under greenhouse conditions. These results suggest that the overexpression of //MusaVicilin// can confer enhanced resistance to BXW and highlight its potential as a candidate gene for genetic engineering resistance to BXW in susceptible cultivars. responses (Macharia //et al//., 2026).
