Relevant studies utilizing various molecular and genomic techniques (RFLP, AFLP, RAPD, SCAR, EST, ISSR, SSR, microsatellites (SSR), SNP and DNA Barcoding) from the Arabian Peninsula were evaluated. The NCBI PubMed was used as a query builder to obtain and filter search results for a decade (2007-2017) which were segregated according to the country and molecular marker. Moreover, our result exhibits extensive use of the DNA barcoding technique than any other molecular and genomic methods in plant biodiversity assessment in method Arabian Peninsula. To provide an evidence on DNA Barcodes generated from Arabian Peninsula in the last ten years, we did a survey on NCBI GenBank and found that the core DNA Barcode marker, “rbcL” was the most sequenced barcode region, followed by matK and ITS2.
