تسجيل النوعEquisetum arvense (ذنب الخيل الحقلي) في الفلورا السورية لأول مرة ومقارنته بالنوع Equisetum telmateia (ذنب الخيل المستنقعي أو العملاق) بالاعتماد على سلسلة الجين rps4

Abstract

Equisetum is a well-known medicinal plant, especially in countries that rely on folk medicine treatment for kidney and urinary tract diseases. A molecular taxonomic study was conducted to distinguish between its types. Samples of E. arvense and E. telmateia were collected from different regions of two cities on the Syrian coast: Latakia and Tartous (Ain al-Laban - Qamin - Al-Khawabi River) between March and May 2015, The samples were classified according to the morphological keys, This showed that it is difficult to distinguish between the two species and their similarity to their phenotypic characteristics such as the cone shape and the number of teeth in the nodes in the stem, So we resorted to rps4 sequencing  as one of the reference genes determine species. The sequence result of both samples was compared with the nucleotide sequence of the rps4 gene from the genomic bank, The study concluded that E. arvense was registered in the first time in Syria and confirmed the classification of  E. telmateia as previously recorded in Syrian flora.
