Chromosome Counts of Some Doronicum (Asteraceae: Senecioneae) Taxa from Turkey

Abstract

In the present study, mitotic chromosome numbers of seven taxa of Doronicum (Asteraceae) from the northeast Anatolia, two of which are endemic to Turkey, were counted. The chromosome counts of D. haussknechtii, D. dolichotrichum, D. maximum and D. reticulatum were reported in this research for the first time. Somatic chromosome numbers were counted using squash preparations obtained from active root tips. All the investigated taxa have been proven to be diploid (2n=60). This research, consistent with the previously reported chromosome counts of the members of Doronicum, has contributed to chromosome number data of the genus.

Taxonomy, Traditional Use and Therapeutic Importance of Genus Doronicum: A Review

“…Bazı taksonlarda ise her iki ploidi seviyesi de görülmektedir ki bu cinste poliploidinin yaygın olduğunu gösterir. Bu taksonlar, D. carpetanum 2n=60, 120 [24,68]; D. clusii 2n=60, 120 [69][70][71]; D. altaicum 2n=30, 60 [72][73][74][75]; D. macrophyllum 2n=30, 60 [67,72,76]; D. oblongifolium 2n=40, 60 [67,72,77]. Gürcistan'dan D. oblongifolium kromozom sayısı 2n=40 olarak bildirilmiştir [77], ancak bu veri x=30 ile tutarsız olan tek çalışmadır ve yeniden sayılması gereklidir [13].…”

Seçilen Anadolu Bitki Türlerinin Antioksidan ve Anti-Büyüme Özellikleri: Heracleum humile, Doronicum reticulatum, Centaurea drabifolia ve Senecio olympicus'un Potansiyelini Keşfetme

“…reticulatum is indigenous to Turkey, Iraq, and Iran (POWO, 2023). The Doronicum genus has been reevaluated to include 30 taxa, 10 of which are distributed in Anatolia with a 30% endemism rate (Güven et al, 2020). Previous research investigated the antioxidant and anti-inflammatory properties of Doronicum austriacum root extract and several fractions of Doronicum pardalianches methanol extract for their efficacy against Alzheimer's disease (Marzocco et al, 2017;Manayi et al, 2021).…”
