Special Issue Information

Dear Colleagues,

The journal Plants will be publishing a Special Issue on Plant tissue culture and secondary metabolites production.

Plant cell tissue and organ culture is an irreplaceable fundamental technique, supplementary to conventional plant breeding, for optimized large-scale clonal propagation, germplasm conservation, somatic embryogenesis and plantlets disease elimination. In addition to these applications, in the last few decades this technique has been intensively utilized for plants that are important from a phytochemical point of view for the biotechnological delivery of pharmacologically relevant secondary metabolites. The latter is of exceptional importance for species which are threatened in their indigenous habitats. So, the use of in vitro culture is a sustainable additive approach to traditional methods of propagation. Furthermore, in vitro culture represents a good method to develop the controlled production of valuable natural metabolites in controlled laboratory conditions without affecting plants’ natural habitats.

This Special Issue aims to conjugate the various aspects of plant cell tissue and organ culture with a special emphasis on the production of phytochemical compounds, valuable for their therapeutic properties such as antioxidant, antiviral, antibacterial and anti-inflammatory properties.

Secondary metabolites play a key role in the diverse defense mechanisms of the plant organism in response to environmental stimuli such as climatic fluctuations, pathogenic organisms, predatory herbivores, as well as competing plants. Therefore, by providing the opportunity for controlled modification of environmental conditions, in vitro culture is an easy-to-manage experimental system, able to be utilized as a source of secondary metabolites delivery for industrial application, as well as for food, cosmetic and pharmaceutical purposes.

This Special Issue will highlight the modern use of different plant cell tissue and organ culture approaches for the successful production of plant secondary metabolites, and especially such with high economic added value.

Plant cell culture offers an alternative to whole plants for the production of biologically important specialised metabolites. In cultured plant cells, manipulation by auxin and cytokinin plant growth regulators (PGRs) may lead to in vitro organogenesis and metabolome changes. In this study, six different combination ratios of 2,4-dichlorophenoxyacetic acid (2,4-D) and benzylaminopurine (BAP) were investigated with the aim to induce indirect organogenesis from Bidens pilosa callus and to investigate the associated induced changes in the metabolomes of these calli. Phenotypic appearance of the calli and total phenolic contents of hydromethanolic extracts indicated underlying biochemical differences that were investigated using untargeted metabolomics, based on ultra-high-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UHPLC–qTOF–MS), combined with multivariate data analysis. The concentration and combination ratios of PGRs were shown to induce differential metabolic responses and, thus, distinct metabolomic profiles, dominated by chlorogenic acids consisting of caffeoyl- and feruloyl-derivatives of quinic acid. Although organogenesis was not achieved, the results demonstrate that exogenous application PGRs can be used to manipulate the metabolome of B. pilosa for in vitro production of specialised metabolites with purported pharmacological properties.

Title: Enhanced in Vitro Production of Secondary Metabolites in Shoot Cultures of Gentianella lutescens J. Holub. by Elicitation

Abstract: This study demonstrated, for the first time, establishment of shoot cultures of rare medicinal plant Gentianella lutescens and compared the chemical profiles of plants collected from nature and those cultured in vitro. Shoot cultures were established from epicotyl explants cultured on MS basal medium with 0.2 mg/l 6-benzylaminopurine (BAP). Five shoot lines were obtained from individual seeds and no significant variations in multiplication rate, elongation and secondary metabolites profile were found among them. HPLC analysis of methanol extracts obtained from in vitro shoots and wild growing plants revealed the presence of secoiridoid gentiopicrin and xanthones – mangiferin, bellidifolin, demethylbellidifolin, demethylbellidifolin-8-O-glucoside and bellidifolin-8-O-glucoside. Although a reduced content of secondary metabolites was detected in shoots cultured in vitro compared to wild growing plants, the obtained results facilitate successful conservation of G. lutescens and pave the way for its effective mass propagation. The effects of BAP, sucrose and abiotic elicitors (salicylic acid, jasmonic acid and methyl jasmonate) on the growth parameters and secondary metabolite production in shoots were also studied. The addition of sucrose and elicitors stimulated xanthone accumulation in shoot cultures, in which the content of the main xanthones was 2-3-fold higher than in controls. Rooting of shoots was very difficult because auxin-induced roots (IBA, NAA, IAA) were poorly elongated. The highest rooting rate (33.3%) was reached in shoots treated for 2 days with 5 mg/l indole-3-butyric acid (IBA) followed by cultivation in PGR-free ½ MS liquid medium for 60 days. Survey of literature revealed a general lack of biotechnological studies on Gentianella species, thus making this research an important contribution to the study of endangered yet unexplored Gentianella species.
