Genetic diversity of Amsonia orientalis

Abstract

Amsonia orientalis Decne. (Apocynaceae), is a rare and threatened plant species which is located only in a constricted area in northeast of Greece and northwest of Turkey in the world. Although phylogenetic analysis depending on nucleotide sequences of genes from different sources (nucleus, mitochondria and chloroplast) became a major tool for classification of plant species, there is still a big lack of information about A. orientalis in the international molecular data bases such as NCBI. In the current study, we phylogenetically analyzed three commonly used molecular markers (18S rDNA, 18S-28S rDNA-ITS region and trnL-F intergenic spacer) from A. orientalis samples collected from Turkey to determine the genetic diversity and also to question the systematic position of A. orientalis. As a result, A. orientalis samples clearly showed close relation with Alyxieae tribe rather than Vinceae. And this result brings the necessity to reconsider the morphological characters that have used to delimit the tribes of Rauvolfioideae.

Effects of zinc and molybdenum on European Bluestar (Amsonia orientalis): An in vitro study

“…The number of these individuals was increased through an in vitro propagation study (1). To determine the genetic consistency among these populations in Balıkesir province, Gürkanlı et al (14) conducted a detailed genetic study, and genetic variation was found between the four different populations. Therefore, only individuals from the Gaziosmanpaşa population were propagated and employed in this study to ensure genetic stability and homogeneity among plantlets.…”
