In the present study, 47 PMEI type 1 genes and 57 PMEI type 2 genes were identified with bioinformatic analysis. The PMEI genes were localized separately on chromosomes 1, 2, 3, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 21 and 22, but mainly at the level of the scaffold. The biological functions of the PMEI type 1 genes were found to be in the areas of biological regulation, metabolism and cellular functions. Their cellular localization appears to be associated with cell parts. For the PMEI type 2 genes, the biological functions were determined as biological regulation, metabolic and cellular functions. A total of 393 Arabidopsis miRNAs targeting 47 olive PMEI type 1 genes were identified. Two specific miRNAs targeting the OePMEI1-07 gene were found (ath-miR8168 and ath-miR774b-5p). For the PMEI type 2 genes, 269 Arabidopsis miRNAs were found, including 14 specific miRNAs targeting OPMEI2-02, OPMEI2-03, OPMEI2-27, OPMEI2-28, OPMEI2-29, OPMEI2-30, OPMEI2-40 and OPMEI2-54. These results suggest that PMEI genes in olives may not only play a role in cell development, germ cell formation and plant growth, but also play an important role in abiotic and biotic stress conditions in the olive.
