In the genus Hypericum, cryoconservation offers a strategy for maintenance of remarkable biodiversity, emerging from large inter- and intra-specific variability in morphological and phytochemical characteristics. Long-term cryostorage thus represents a proper tool for preservation of genetic resources of endangered and threatened Hypericum species or new somaclonal variants with unique properti...

The effect of the gene dosage on the expression of rRNAs was studied in Hypericum perforatum. The methylation levels of rDNA were analysed using the isoschizomers MspI and HpaII and eleven additional methylation-sensitive enzymes. No differences in rDNA methylation were observed between diploids and tetraploids at an early ontogenetic stage.
The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of six Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists. Samples collected between June and Aug...
The aim of this study was to evaluate the non-enzymatic and enzymatic antioxidant response fifteen Hypericum perforatum L. dark-grown (HR1 A-HR1 O) photoperiod-exposed (HR2 A-HR2 hairy root clones. Dark-grown HR1 clones were characterized with high biomass accumulation up-regulated phenylpropanoid metabolism through phenylalanine ammonia lyase (PAL)-mediated production flavonoids, flavan-3-ols ...
