A Comparison Study of Chloroplast Genomes: Ficus Species Versus İts Close Relatives
Ficus genus, mostly known as fig trees, contains about 850 species in the Moraceae family. This genus is vital due to its agronomical properties that the “fig” fruits are essential sources of flavonoids, sugars, vitamins A and C, acids and enzymes. Ficus genus is also an important part of the biodiversity of the rainforest ecosystem. Also, the previous studies showed that Ficus racemosa was found as one of the important medicinal plants for various diseases including diabetes, respiratory and urinary problems. In our study, we decided to analyze a chloroplast genome from an important Ficus species: Ficus racemosa. We re-assembled the chloroplast genome of Ficus racemosa which results of 160,383 bp with a typical circular structure, and we found that the chloroplast genome contains total of 82 protein-coding genes, 56 tRNAs, and seven rRNA genes. Additionally, we also analyzed the chloroplast genomes of Ficus carica, Ricinus communis, Vitis vinifera and Ziziphus jujuba for the further comparative studies. Repeat elements, Simple Sequence Repeats (SSRs), and phylogenetic tree analyses were conducted on the chloroplast genomes of all organisms and the results were compared. These findings presented in this study shows the level of chloroplast genome conservation, and the results will be discussed to provide clues for the understanding of the evolution of organellar genomes in tree species.
