Special Issue Information

Dear Colleagues,

Medicinal plants play critical roles in human wellbeing as sources of medicines, nutraceuticals, and cosmeceuticals, amongst other things. They also play important roles in ethnoveterinary medicine. They are important raw materials in the production of many health products. The commercialization of medicinal plant products is dependent on the sustainable supply of high-quality medicinal plants as raw materials. Wild harvesting is no longer sustainable for many commercially important species. Thus, medicinal plant cultivation has become an integral part of a sustainable medicinal plant value chain. Large-scale cultivation requires the availability of sufficient propagules. Different factors can influence their seed propagation. In some cases, particularly for medicinal plants where the underground parts are used medicinally, the availability of propagules can present a challenge. This necessitates developing and optimizing their propagation protocols. Several cultivation practices can influence the biomass production, phytochemical content, and biological activity of cultivated plants. This Special Issue of Plants is expected to contribute to the current knowledge on medicinal plant propagation (in vitro and ex vitro) and cultivation. Research and review manuscripts demonstrating or highlighting the influence of factors such as plant growth regulators, media additives, biostimulants, pruning, spacing, and other agronomic factors on propagation (including seed germination), biomass production, bioactive compound profiles, and the safety as well as efficacy of medicinal plants fall within the scope of this Special Issue.

Galanthamine is an immensely valuable alkaloid exhibiting anti-cancer and antiviral activity. The cultivation of plant tissues in in vitro conditions is a good source for the synthesis and enrichment of secondary metabolites of commercial interest. In this study, the Amaryllidaceae alkaloid galanthamine was quantified in three Zephyranthes species, such as Zephyranthes candida, Zephyranthes grandiflora, and Zephyranthes citrina, and the impact of the methyl jasmonate (MJ) signaling molecule on galanthamine accumulation was monitored in in vitro-derived plant tissues. This is the first ever study of the MJ-regulated accumulation of galanthamine in in vitro-grown Zephyranthes tissues. Shoot regeneration was obtained in all three Zephyranthes species on Murashige and Skoog (MS) medium containing 2.0 mgL−1 benzylaminopurine (BAP) + 0.5 mgL−1 naphthalene acetic acid (NAA). The regenerated shoots were rooted on a medium containing 2.0 mgL−1 indole butyric acid (IBA). A GC-MS study of Zephyranthes extracts revealed the presence of 34 phyto-compounds of varied levels with therapeutic activities against diseases. The galanthamine content was quantified in plant parts of the three Zephyranthes species using high-performance thin layer chromatography (HPTLC); the maximum was found in Z. candida bulb (2.41 µg g−1 dry wt.), followed by Z. grandiflora (2.13 µg g−1 dry wt.), and then Z. citrina (2.02 µg g−1 dry wt.). The galanthamine content showed bulb > leaf > root source order. The in vitro-generated plantlets were treated with different MJ concentrations, and the galanthamine yield was measured in bulb, leaf, and root tissues. The highest galanthamine content was recorded in bulbs of Z. candida (3.97 µg g−1 dry wt.) treated with 150 µM MJ, showing an increase of 64.73% compared to the control. This accumulation may be attributed to MJ-induced stress, highlighting the potential commercial synthesis of galanthamine in vitro. Full article
