The first complete chloroplast genome sequences of Pistacia eurycarpa Yalt, a horticultural important rootstock and industrial tree

Abstract

AbstractPistacia genus is botanically classified in the Sapindales order and the Anacardiaceae family, and the member of this genus P. eurycarpa is used as a rootstock for pistachio. Due to its rich oil content, various soaps are produced from the green peels of P. eurycarpa nuts and are used in the cosmetic industry as soap. In the current study, we aimed to release the complete chloroplast genome of P. eurycarpa to detect the relationship of the members of the Sapindales and also Pistacia genus. The length of the chloroplast genome of P. eurycarpa was identified 160,693 (bp) and consisted of the distinct parts of the genomic fragments such as LSC, SSC, and IR regions. The length of the LSC was 88,410 (bp), and SSC genomic range represented a total of 19,087 (bp). Inverted regions length was 26,598 (bp). A total of 125 genes were determined within the whole chloroplast genome of P. eurycarpa. The number of simple sequence repeats (SSRs) in the chloroplast genome was computed as 74. Three main clusters defined the dendrogram of all accessions. The closest pairs of species were identified among the P. eurycarpa and P. vera species. The farthest genetic relationship was calculated among the members of the Sapindales species Mangifera indica and the Fagales species Castanea mollissima. The sequences of the chloroplast genome of P. eurycarpa species can be evaluated for the construction of the basis of the complete evolution of the order, genera, and the development of the SSRs for species-specific markers for revealing the evolution of Pistacia species for future breeding research.
