Cognate avirulence genes: TAL effector genes. Neutralized by interfering TAL effectors, so-called iTALEs or truncTALEs (Ji //et al//., 2016; Read //et al//., 2016). A novel variant of the //Xa1// gene (Os04g53120) from the rice variety SK20-28 (derived from a cross between Giganté and Kogoni 91-1) is characterized by a short deletion in the effector-binding element (EBE) of TAL effector, an extended leucine-rich repeat (LRR) domain and enhanced recognition specifcity toward local //Xanthomonas oryzae// pathotypes in Mali (Tekete //et al.//, 2026).

 The immune receptor XA21 is cleaved by the rhomboid-like protease OsRBL3b, likely within its transmembrane domain, which protects grain set and male fertility in rice. This balance between reproduction and disease resistance through the specific expression of a rhomboid protease may be key to limiting the detrimental effects of an active immune response (Vergish et al., 2025). The immune receptor XA21 is cleaved by the rhomboid-like protease OsRBL3b, likely within its transmembrane domain, which protects grain set and male fertility in rice. This balance between reproduction and disease resistance through the specific expression of a rhomboid protease may be key to limiting the detrimental effects of an active immune response (Vergish et al., 2025).
  
 +The small secreted peptide OsRALF26, previously identified as an //Oryza//-specific ligand for FERONIA-like receptor 1 (OsFLR1), is also directly perceived by XA21. OsRALF26 as a host-derived ligand of XA21 is required for full activation of XA21-mediated immunity in distal tissues, consistent with a role for OsRALF26 in spatial propagation of XA21-dependent defence (Kwon //et al.//, 2026).

 +Member of the nucleotide-binding site and leucine-rich repeat (NLR) receptor family. XA48 perceives the ancient pathogen effector XopG, activating effector-triggered immunity by degrading the negative regulator OsVOZ1/2 (Lin //et al.//, 2026).
