Abstract. Rehman A, Saeed S, Ahmed A. 2021. Genetic diversity and population structure of Seriphidium Sub-genus of Artemisia from different terrains of Balochistan, Pakistan. Biodiversitas 22: 2658-2664. Seriphidium is one of the largest sub-genus of Artemisia growing in different geographical populations and terrains of Balochistan Pakistan. This genus is economically important and used as folk medicine. The genus is highly variable, besides morphological characterization, molecular authentication is also needed for novel drug discovery. Three significant species of the genus viz., S. quettense, S. oliverianum, and S. maritimum were selected for morphological and molecular characterization and phytochemical investigation. Genetic variability assessment was carried out by polymorphic bands analysis by using molecular markers in 18 accessions collected from two sites, namely, Ziarat and Hazarganji-Chiltan National Park, Balochistan, Pakistan. A combined molecular marker system by using 17 Randomly Amplified Polymorphic DNA (RAPD) and 9 Inter-Simple Sequence Repeats (ISSR) amplified 231 loci, of which 111 were polymorphic (48% polymorphism). Phenolic contents and Flavonoids were estimated for phytochemical assessment. Results revealed that the highest phenolic compounds were in S. quettense when compared with other investigated taxa. In conclusion, molecular marker profiling together with phytochemical variation of all three species exhibited genetic diversity and chemical variation. The findings of the current investigation can further be used as a baseline study for the implementation of conservation strategies. In addition, phytochemical assessment can be utilized for modern drug discovery

Abstract.  Gul J, Saeed S, Ahmed A, Leghari SK, Basit A, Rehman A, Khan MZ. 2021. Genetic diversity and morphological variation of Pinus gerardiana along the environmental gradient from Zhob, Balochistan, Pakistan. Nusantara Bioscience 13: 121-128. Pinus gerardiana, an evergreen gymnosperm, is an economically- and ecologically valuable tree found in the Takhte Suleman Mountain Range, Zhob northeastern edge of the Balochistan, Pakistan. The present study is based on the assessment of the impact of environmental gradients with special reference to altitudinal gradient and soil variables on morphological, phytochemicals and genetic variation of P. gerardiana. A total of 27 genotypes of P. gerardiana were collected from the three elevation zones ranging from 2000 - 3500 m above sea level. The genetic diversity was assessed by combined markers, the random amplified polymorphic DNA (RAPD) and the Inter Simple Sequence Repeat (ISSR). Polymorphic bands analyzed the data to generate a dendrogram, based on the unweighted pair group method with arithmetic mean (UPGMA). Morphological characters assessed the morphological characters. Phytochemicals were investigated; the total phenolic content and total flavonoid contents were estimated and compared amongst all accessions. Our results revealed variations along altitudinal gradients and related to soil characteristics. The populations at the Middle altitude zone have greater diversity than populations at lower and higher altitudes. The resulting altitudinal variation can be attributed to various geographical and environmental conditions. These results can help in conservation and cultivation of this economically important tree.
