The complete chloroplast genome of a centennial olive tree (Olea europaea, Oleaceae) from the southern Peruvian coast

Abstract

Olive (Olea europaea Linaeus 1753) is one of the valuable fruit trees and very important edible oil plant in the world. The chloroplast (cp) genome of an olive tree (Olea europaea) from the southern Peruvian arid coast was obtained for the first time. Genomic DNA of high quality was used to generate librarieswith Illumina Hiseq paired-end methods. The cp genome is 155,886 pb in length and contains a large single-copy region (LSC) of 86,610 pb and a small single copy region (SSC) of 17,790 pb separated by two inverted repeat (IR) regions (25,741bp). The cp genome of olive contains 124 genes that consists of 80 protein-coding genes, 36 tRNA, eight rRNA. Phylogenetic analysis showed this olive tree is sister to O. europaea subsp. maroccana ( Oleeae tribe). This study presents the first overview of the chloroplast genome organization and phylogenetics of O. europaea, offering valuable insights for genetic and evolutionary research in the genus Olea.
