Abstract
This study examined the degree of variations in DNA fingerprints associated with slight altitudinal change of Schinus molle grown in Abha region, Saudi Arabia. Seven populations from Schinus molle plants located at 2193.0, 2246.0, 2197.7, 2441.0, 2372.0, 2250.6 and 2175.0 meters had been investigated. The degree of genetic variability was evaluated using random amplified polymorphic DNA (RAPD), mixed RAPD and intersimple sequence repeat markers (ISSR). The genetic similarity coefficients from RAPD analysis revealed the maximum similarity value (89.9%) was between population at 2250.6 m and population at 2175.0 m. The genetic similarity coefficients from mixed RAPD primers displayed the highest similarity value (87.6%) between population at 2246.0 m and population at 2197.7 m. Similarity coefficients from ISSR analysis revealed the highest similarity value (86.2%) among populations at 2193.0 m, 2246.0 m, 2441.0 m and at 2250.6 m. Super tree analysis (RAPD + mixed RAPD + ISSR) showed the highest similarity value (85.5%) between population at 2441.0 m and population at 2250.6 m. In conclusion, marker systems including RAPD, mixed RAPD and ISSR, alone or combined can be effectively used in determining the genetic relationship among Schinus molle plants even at very close populations.Bangladesh J.

Highlights
Abha region has a specialized environmental condition among all other areas in the Kingdom of Saudi Arabia which have an indirect effect on the weed plants growth
This research article reports the use of the random amplified polymorphic DNA (RAPD), mixed RAPD and intersimple sequence repeat markers (ISSR) makers to the S. molle plant and revealed its efficiency to determinate the DNA fingerprints
It revealed that RAPD, mixed RAPD and ISSR markers could be used alone or in combination to estimate the genetic diversifications of S. molle plants
Summary
Abha region has a specialized environmental condition among all other areas in the Kingdom of Saudi Arabia which have an indirect effect on the weed plants growth. S. molle plants (family, Anacardiaceae) are among the most common weed in Saudi Arabia especially in Tharawat Mountains. S. molle plants usually used for the restoration of degraded areas and showed tolerance to heavy metals (Doganlar et al, 2012; Pereira et al, 2016). Toward this approach examine the genetic diversity of S. molle plant is highly needed as no reports available
