| dc.description.abstract | The Hypericum L. taxon, which is the largest genus of the Hypericaceae family, has a very wide distribution and includes approximately 500 species. The species of the genus Hypericum attract great attention all over the world due to their medicinal properties. In vitro culture techniques are one of the most preferred tools for both micropropagation and the study of secondary metabolites of the genus. Plant growth regulators (PGRs) are organic molecules that affect different processes of the plant, such as growth and morphogenesis at low concentrations. Naturally occurring plant growth regulators are called phytohormones. Phytohormones are generally known as auxins, cytokinins, gibberellins, abscisic acid, and ethylene, and auxins and cytokinins are the most important phytohormones for micropropagation. In addition, polyamines, jasmonates, salicylic acid. and brassinosteroids are used in scientific research as PGRs. Various concentrations of auxins and cytokinins are important in determining whether the respective cultures develop shoot formation (high concentration of cytokine and low concentration of auxin), root formation (low concentration of cytokine and high concentration of auxin), or callus formation (different concentrations of both) in ex situ in vitro conservation. The micropropagation technique, one of the biotechnological methods, is accepted as an effective alternative to traditional propagation methods since it allows many plants to be grown in a short time and limited area. The micropropagation technique is very useful in the protection of endemic and/or endangered plants, which have a low propagation rate and are very difficult to reproduce with traditional techniques. The establishment or optimization of effective micropropagation protocols is very important for the execution and maintenance of ex situ in vitro conservation programs. © 2023 Elsevier Inc.
