The APETALA2/ethylene response factor (AP2/ERF) gene family is known to play a key role in the regulating expression of several genes in response to biotic and abiotic stress, conferring an evolutionary advantage to plants. In zoysiagrass, the genetic information of the ERF transcription factors (TF) is limited, leading to gaps in our understanding of the differential response of the zoysiagrasses to external stimuli. In this study, ERF1/2 genes in Zoysia matrella and Z. pacifica were predicted. We present a comparative study of the ERF1/2 TF among the three Zoysia species, with an overview of their putative gene structures, phylogeny, conserved motifs, and putative protein structure. Our study revealed one ERF1 and ERF2 TF in Z. pacifica, but Z. matrella had two copies of each ERF1 and ERF2 TF genes. All the ERF1 genes had no introns, while the ERF2 genes exhibited one intron. One AP2/ERF domain was predicted in all the ERF TF genes. Within the AP2 conserved domain of the four Zoysia ERF1 genes, a single amino acid substitution (Ala64 → Thr64), as a result of a missense mutation (GCC to ACC) was seen to affect the active ligand- binding site in the GCC-box-domain. The analysis of the upstream regulatory region of the ERF1/2 revealed transcriptional binding motifs linked to regulate the response of ERF genes to abiotic and biotic stresses.
