Genome-wide identification and characterization of Ethylene-Insensitive 3 (EIN3/EIL) gene family in Camellia oleifera.

ABSTRACT: Camellia oleifera, a vital woody oil crop in China, suffers substantial yield losses due to frequent physiological fruit abscission during cultivation. Ethylene signaling, mediated by Ethylene-Insensitive3/Ethylene-Insensitive 3-like (EIN3/EIL) transcription factors encoded by a multigene family, plays a pivotal role in plant organ abscission. However, the EIN3/EIL family remains understudied in C. oleifera. Here, genome-wide analysis identified four CoEIL genes encoding proteins with conserved EIN3 domains. Phylogenetic classification grouped these proteins into Group A and Group B, revealing evolutionary proximity between C. oleifera and tea (Camellia sinensis). Cis-acting regulatory element analysis implicated CoEIL genes in hormone responsiveness and stress adaptation. Quantitative rea
