SUMMARY Plant immune receptors and their natural variations play a central role in combating disease‐causing pathogens. These include intracellular nucleotide‐binding leucine‐rich repeat (LRR) (NLRs) cell‐surface pattern recognition (PRRs) that can be further classified as receptor‐like proteins (RLPs) kinases (RLKs). Although the NLRome has been characterized, repertoire extent of diversity PRRome remain undetermined rice. In this study, we examined receptor genes using high‐quality genomes 309 rice accessions from 8 species within genus Oryza . A total 376 310 were identified, including 149 592 NLR‐coding 226 718 PRR coding genes. Shannon entropy analysis revealed set display significant intra‐species inter‐species general, RLPs are more variable than RLKs, while NLRs LRR‐RLPs LRR‐RLKs. Additionally, NLR exhibit contrasting shoot/root expression patterns, with generally skewed towards root expression. Furthermore, found size LRR‐RLK gene families correlates local annual precipitation, suggesting stronger selection pressure on grown under wet conditions dry conditions. sum, pan‐genomic not only reveals extensive repertoires but also provides potential target for improving disease resistance

Ribose 2′-O-methylation (Nm), a key RNA modification, is catalyzed by diverse 2′-O-methyltransferases (2′-O-MTases), yet the evolutionary trajectories of these enzymes remain poorly studied. Here, with comprehensive collection functionally validated 2′-O-MTases, we classified them into 11 families based on distinct methyltransferase (MTase) domains. Homology searches across 198 species identified 6746 proteins, revealing widespread distribution 2′-O-MTases Tree Life. Eight MTase domains (e.g., FtsJ, SpoU-methylase) existed both in eukaryotes and prokaryotes, indicating their ancient origin Last Universal Common Ancestor (LUCA). In contrast, AdoMet-MTase, TRM13, Trm56 are lineage-specific. Copy number expansion most 2′-O-MTase occurred as life evolved from prokaryotes to eukaryotes, where they might engage more complex regulation cell differentiation development. Domain composition, Ka/Ks ratio, domain structural analyses showed that purifying selection conserved catalytic families, despite frequent integration auxiliary Notably, FtsJ family diverged three deeply separated lineages via remodeling pocket, each lineage specializing methylation mRNA caps, rRNA, or tRNA. These findings illuminate trajectory highlighting multiple origins functional diversification.
