Introduction

Hypericum is one of nine genera and represents approximately 80%of the diversity of the family Hypericaceae Juss. This genus is originated from Eurasia and widely distributed in tropical and subtropical regions. Species of this genus grow on damp soils, meadows, and swamps.

Morphologically Hypericum genus are characterized by the presence of different kinds of secretory glands and channels, including transparent, dark glands. The secretory structures are the

accumulation of biologically active substances, and their various configurations are important in the classification of the genus.

Species of this genus are annual and perennial herbaceous, semi-shrubs, and shrubs. The leaves are opposite, rarely whorled, whole-edged, sessile, or with short petioles on the surface and at the edges often with transparent, sometimes with black point glands. Flowers are collected in the corymbose inflorescence.

Plant material and DNA extraction Fieldwork was conducted during the expeditions (2015-2018) between May September, at different stages of plant development (Table 1). Dried herbarium specimens deposited in the Herbarium fond of the Institute of Botany ANAS (BAK) and were examined according to standard procedures.

Also, the Herbarium specimens stored in the Herbarium fond of the Institute of Botany Azerbaijan NAS were used in this study. Classic comparative morphological and results of the molecular-phylogenetic analysis were used for the identification of species. From each sample of 100-200 mg of young leave plants put in 2 ml tubes. Leaf material was obtained from three individual plants per accession, flash-frozen in liquid nitrogen, and stored at -200 °C.

The buffer is added to the dried DNA and stored in the refrigerator for 1 night. Amplification reactions were shown in Table 2.

Amplifications were performed as follows: first denaturation (3 min at 94 °C), 35 cycles of denaturation (15 s at 94 °C), elongation (at 72 °C), and final extension of (5 min at 72 °C). The amplified products were precipitated with ice-cold ethanol, washedwith70% ethanol, and dissolved in water. PCR products were verified byelectrophoresison1.5% agarose gels containing ethidium bromide in this-acetate EDTA (TAE) buffer and detected under UV light (Table 2).

The restriction fragments with 100 bladders (Gene Ruler TM 100 bp ladder, Fermentas) as a size marker were separated on 1% agarose gels in Tris-acetate EDTA (TAE) buffer (Figure 1).

Checking the amount and purity of DNA The amount of DNA is determined by a spectrophotometer (260 and 280 nm) (Nano Drop 200 °C UV-VisSpectrophotometer-Thermo Scientific). The mixture was used to determine the amount of 20 |l extracted DNA and 1980 |l of DD H2O. The density of theDNAsolutioniscalculated as follows: DNA density (NG/|l) = (0S260H100 (dilution factor) x 50 ng/ml) / 1000. The optical densityratiobetween260and280 nm (OS26 0/0S280) shows the purity of sound acids. The optimum cleaning speed for the PCR is 8-2.0. After determining the amount of DNA, from each sample, are prepared 50 ng / [j.1 of DNA for each PCR reaction.

PCR reaction with its primers The total volume of reactionfor1sampleis20 |il (2 |il of DNA sample + 18 |il of the reaction mixture). The whole reaction should be arried outside the ice and the unit needs to be centrifuged. The tags added to theology measure action mixture, stirring, and the total reaction mix tourist thoroughly vortex. The amount of DNA is pre-placed in a tube or RDA (plate) and then stop resonance. Then, 18 |il is poured from the reaction mixture onto each sample and swirled again. After the reaction tube is placed in the apparatus PCR (Gene Amp System 2720, Applied Biosystems Foster City, CA and BigDyeTerminator v3.1 Cycle) and the programs are compiled in the following sequence.
