Abstract

In vitro culture technique is an effective method for plant propagation to overcome the limitations of conventional cultivation. This method is used to improve accumulation of plant secondary metabolites. The purpose of this study is to review the development of micropropagation and improving secondary metabolites in Stevia rebaudiana and Curcuma plants through the application of precursors and elicitors. The systematic literature review is used to analyse scientific articles or publications from 2000 to 2025 obtained from various online databases using relevant keywords. The results showed that Stevia was more studied when compared to Curcuma due to its high economic value, with significant impact on the study of improving accumulation of stevioside and rebaudioside production through several elicitor and precursors. In Curcuma, beside in vitro culture for mass propagation, the response to in vitro treatment of elicitor dan precursors were varied, but some precursors such as phenylalanine were shown to improve curcuminoid accumulation. In conclusion, tissue culture techniques and the use of elicitor and precursor for improving secondary metabolites accumulation have the potential impact to support mass propagation, production and sustainable optimization of plant bioactive compounds.

Abstract

Indonesia’s rich plant biodiversity offers a wide array of secondary metabolites, including essential oils, known for their antioxidant, antifungal, and antibacterial properties. This review article examines the secondary metabolite composition of essential oils from various plant species by synthesizing findings from existing literature. The review article highlights the presence of diverse compounds, including terpenes, phenols, and alkaloids, with variations observed between species—for instance, limonin in citrus, linalool in ylang-ylang, and eugenol in cloves. Commonly utilized methodologies, such as steam distillation and GC-MS analysis, discuss their effectiveness in characterizing essential oil components. The findings underscore the extensive potential of crucial oils for applications in health, food, and cosmetic industries, providing a foundation for future research and practical innovations.

Abstract

Plants of the Brassicaceae family display a highly complex and adaptive chemical defense system against biotic stresses, particularly herbivore attack. These defense mechanisms are physiologically based on the biosynthesis and activation of secondary metabolites, mainly glucosinolates, which are converted into toxic compounds such as isothiocyanates by the enzyme myrosinase upon tissue damage. This response is not only local, but also systemic, involving cross-interactions between roots and leaves, and is modulated by the hormones jasmonate (JA), salicylate (SA), and ethylene (ET). These complex interactions form a plant defense system that can be explicitly induced depending on the type and sequence of herbivore attack. In addition, molecular adaptation strategies, such as MYB gene expression, and engineering technologies, such as CRISPR/Cas9, have opened up opportunities to improve plant resistance. This study aims to analyze the physiological dynamics of Brassicaceae defense mechanisms, evaluate the role of hormonal and genetic regulation in enhancing plant resistance, and address the critical challenges posed by specialist herbivore adaptations and the socio-environmental implications of genetic engineering. By synthesizing these elements, this article presents a comprehensive review of the potential of these defense systems in advancing sustainable agriculture and promoting human health.
