The nuclear-localized ethylene-insensitive3/ethylene-insensitive3-like (EIN3/EIL) proteins regulate the ethylene signaling pathway for growth and stress responses. This study presents a genome-wide analysis of nine Oryza sativa EIN3/EIL genes, exhibiting three clads in an ML phylogenetic tree. These are conserved both exon-intron organization motif architecture aligned with their clustering. harbor EIN3, EIN3 superfamily, RDV-p3 domains. OsEIN3/EIL expression profiling revealed consistently high transcript levels LOC_Os03g20790 LOC_Os02g36510 leaf blades across vegetative reproductive stages endosperm, indicating potential role yield enhancement. Additionally, LOC_Os03g20790, LOC_Os02g36510, LOC_Os07g48630, LOC_Os09g31400 highly expressed at later root development, showing nutrient seed-filling. Moreover, elevated LOC_Os04g38400, LOC_Os09g31400, LOC_Os08g39830, LOC_Os07g48630 were detected under mannitol treatment, while LOC_Os04g38400 LOC_Os08g39830 upregulated tissues drought exposure. genes also intricately interacted MPK1, MPK5, MYC underscoring involvement tolerance. Altogether, our findings lay foundation improved rice
