-Extracellular ribonuclease LE-like, encodes for hypersensitive response assisting protein, ribonuclease T2 activity, RNA binding. Role in intensifying the hypersensitive response mediated by harpinPSS (harpin derived from //Pseudomonas syringae// pv.// syringae//) by dissociating multimeric forms of the hairpin into dimers and monomers that trigger stronger hypersensitive cell death necrosis (Tripathi //et al.//, 2014).+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).
