Molecular Identification of Morus ssp. in Duhok Using Nuclear ITS Region and Chloroplast Matk Gene

Since Mulberries (Morus)is a tree species with a considerable plant variety. Molecular techniques are methods used to distinguish between species accurately, easily and quickly. This study examines a Molecular method for distinguishing different Morus species in the Duhok - Kurdistan region/ Iraq. The method is based on the use of four techniques: matK gene, the ITS region, PCR-RFLP, and SRAP markers. Twelve Morus species have been selected for this study from different region of Duhok. The ITS region's PCR result was 700 bp, but the matK gene's PCR produce was 900 bp. The same restriction site was found for all utilized cultivars when the 700bp of ITS fragment was used for PCR-RFLP with two restriction enzymes, RsaI GT/AC and HaeIII GG/CC. This study also used six combinations of SRAP markers to aid in grouping and identifying genetic similarities. The results of PCR-RFLP demonstrated an insufficient link between Morus physical appearance and genetic traits, but differences across studied cultivars could be identified using SRAP markers. Furthermore, this study demonstrated the possibility of DNA barcoding Morus cultivars, as well as additional sequence analysis and the identification of probable SNP between cultivars.
