UNASSIGNED: Elaeagnaceae, which harbor @entity1568 -fixing actinomycetes, is a plant family of the Rosales and sister to Rhamnaceae, Barbeyaceae and Dirachmaceae. The results of previous molecular studies have not strongly supported the families of Elaeagnaceae, Rhamnaceae, Barbeyaceae and Dirachmaceae. However, chloroplast genome studies provide valuable phylogenetic information; therefore, we determined the chloroplast genome of Elaeaganus macrophylla and compared it to that of Rosales such as IR junction and @entity13089 gene. The chloroplast genome of Elaeagnus macrophylla is 152,224 bp in length and the @entity13089 gene of E. macrophylla was psuedogenation. Phylogenetic analyses based on 79 genes in 30 species revealed that Elaeagnus was closely related to Morus. Comparison of the IR junction in six other rosids revealed that the @entity68448 gene contained the LSC region, whereas E. macrophylla contained a @entity68448 gene duplication in the IR region. Comparison of the LSC/IRb (JLB) and the IRa/LSC (JLA) regions of Elaeagnaceae (Elaeagnus and Shephedia) and Rhamnaceae (Rhamnus) showed that @entity68448 gene duplication only occurred in the Elaeagnaceae. The complete chloroplast genome of Elaeagnus macrophylla provides unique characteristics in rosids. The @entity13089 gene has been lost or transferred to the nucleus in rosids, while E. macrophylla lost the @entity13089 gene. Evaluation of the chloroplast genome of Elaeagnus revealed @entity68448 gene duplication for the first time in rosids. The availability of Elaeagnus cp genomes provides valuable information describing the relationship of Elaeagnaceae, Barbeyaceae and Dirachmaceae, IR junction that will be valuable to future systematics studies.
