Phytochemical characterization of callus cultures from the endangered plant Crocus scepusiensis (Rehm. & Woł.) Borbás ex Kulcz.
Crocus scepusiensis (Rehm. & Woł.) Borbás ex Kulcz., a critically endangered herbaceous plant which serves as a valuable source of bioactive compounds found across Europe and Asia. The aim of this study was to produce a calli from two different plant parts (leaf and shoot tip) for the critically endangered C. scepusiensis through tissue culture techniques, characterize the resulting calli through chemical profiling, with a focus on identifying key phytoconstituents, and lay the groundwork for future research on the biological activities of these calli extracts. Leaf disc and micro shoot tip explants were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations of 6-benzylaminopurine (BA) and α-naphthaleneacetic acid (NAA) to induce organogenic calli. The resulting calli exhibited distinct biochemical profiles. Moreover, a phytochemical analysis was conducted to compare the metabolite composition of callus 1 (derived from leaf discs) and callus 2 (derived from shoot tips). Callus 1 displayed a higher total phenolic content (30.3558 ± 1.3564 mg (GAE)/g) compared to callus 2 (29.1543 ± 0.9754 mg (GAE)/g). Similarly, callus 1 exhibited a greater total flavonoid content (26.0089 ± 1.8029 mg (RE)/g) than callus 2 (18.4464 ± 1.4797 mg (RE)/g). Liquid chromatography-photodiode array-electrospray ionization-tandem mass spectrometry (LC-PDA-ESI-MS/MS) analysis revealed the presence of 26 and 25 constituents in callus 1 and 2, respectively. Fourteen and thirteen of these identified compounds have been previously reported in other Crocus species, with 22 constituents common to both calli. Twelve constituents were reported here in Crocus for the first time as far as we know.
期刊介绍:
This journal highlights the myriad breakthrough technologies and discoveries in plant biology and biotechnology. Plant Cell, Tissue and Organ Culture (PCTOC: Journal of Plant Biotechnology) details high-throughput analysis of gene function and expression, gene silencing and overexpression analyses, RNAi, siRNA, and miRNA studies, and much more. It examines the transcriptional and/or translational events involved in gene regulation as well as those molecular controls involved in morphogenesis of plant cells and tissues.
The journal also covers practical and applied plant biotechnology, including regeneration, organogenesis and somatic embryogenesis, gene transfer, gene flow, secondary metabolites, metabolic engineering, and impact of transgene(s) dissemination into managed and unmanaged plant systems.
