In this study, plant samples of Astragalus L. genus were collected from 42 different locations of Erzincan in the vegetation period of 2021. As a result of the plant identification studies, 12 taxa (A. pennatulus, A. compactus, A. aduncus, A. xylobasis, A. angustifolius subsp. angustifolius, A. karamasicus,A. kurdicus, A. cancellatus, A. eriocephalus subsp. Eriocephalus, A. lycius, A. microcephalus, A. lagurus) were determined. 3 of them (Astragalus pennatulus, Astragalus karamasicus, Astragalus lycius) are endemic. The genetic relationship between the identified species was investigated with ISSR (inter-simple sequence repeat) molecular markers. 16 primers (UBC868, UBC817, UBC807, UBC812, UBC816, UBC825, UBC824, UBC830, UBC836, UBC840, UBC848, UBC855, UBS856, UBC841, UBC842, UBC61) were used in the ISSR method. According to the PCR results, the primers studied gave bands of 100-2000 bp in length. Polymorphism was calculated as 90.8% according to ISSR primers. Dendrograms were created using the ISSR data and the UPGMA method. While the highest genetic similarity was observed between A. kurdicus and A. angustifolius supsp angustifolius taxa, the lowest genetic similarity was observed between A. angustifolius subsp angustifolius and A. pennatulus taxa. These studied markers turned out to be suitable for characterizing genetic diversity between Astragalus species.
Bu çalışmada, 2021 yılının vejetasyon döneminde Erzincan’daki 42 farklı lokaliteden Astragalus L. cinsine ait bitki örnekleri toplanmıştır. Yapılan bitki tayini çalışmaları sonucunda 12 takson (A. pennatulus, A. compactus, A. aduncus, A. xylobasis, A. angustifolius subsp. angustifolius, A. karamasicus,A. kurdicus, A. cancellatus, A. eriocephalus subsp. eriocephalus, A. lycius, A. microcephalus, A. lagurus) belirlenmiştir. Bunlardan 3’ü (Astragalus pennatulus, Astragalus karamasicus, Astragalus lycius) endemiktir. Belirlenen türler arasındaki genetik ilişkiler ISSR moleküler markırları ile araştırılmıştır. ISSR (kısa dizi tekrarları arası) yönteminde 16 primer (UBC868, UBC817, UBC807, UBC812, UBC816, UBC825, UBC824, UBC830, UBC836, UBC840, UBC848, UBC855, UBS856, UBC841, UBC842, UBC61) kullanılmıştır. PCR sonuçlarına gore, çalışılan primerler 100-2000 bç uzunluğunda bantlar vermiştir. ISSR primerlerine göre polimorfizm % 90.8 hesaplanmıştır. ISSR verileri ile UPGMA yöntemi kullanılarak dendrogramlar oluşturulmuştur. En yüksek genetik benzerlik A. kurdicus ile A. angustifolius supsp angustifolius taksonları arasında gözlenirken, en düşük genetik benzerlik A. angustifolius subsp angustifolius ile A. pennatulus taksonları arasında gözlenmiştir. Çalışılan bu markerlar Astragalus türleri arasındaki genetik benzerliği karakterize etmede uygun markırlar olduğunu ortaya çıkarmıştır.
