Objective: To study the effect of several factors on the quantity of hypericin in H. perforatum callus.

Method: High efficiency liquid phase chromatography and plant tissue culture were applied.

Result And Conclusion: When the ratio of nitro-nitrogen to amina-nitrogen is 3:1, the callus biomass is 1.6-fold and the synthetic mass of hypericin rises. 0.1-0.20 mg x L(-1) mannose improves the content of total hypericin. The addition of PVP or PVPP can promote improvement of the growth and biosynthesis of callus.

In order to scientifically search for new sources of secondary metabolites with valuable qualities for phytopharmacognosy, tasks requiring a step-by-step solution were set. The primary task is the development of technologies for obtaining in vitro highly productive biomass of cells of relict gymnosperms of the genus , capable of accumulating various classes of secondary metabolites. The study of the accumulation and localization of secondary metabolites allowed us to evaluate the biological activity and cytotoxicity of in vitro cultures.

The objective of present review is to provide a scientific overview of sugarcane as a potential feedstock for biofuel and use of genome editing approach for improvement of industrial and agronomical traits in sugarcane. Sugarcane, a perennial tropical grass with a high biomass index, is a promising feedstock for bioethanol production, and its bagasse, rich in lignocellulosic material, serves as an ideal feedstock for producing second-generation bioethanol. To improve the conversion of sugarcane biomass into biofuels, developing varieties with improved biomass degradability and high biomass and sucrose content is essential.

Background: Spine grape (Vitis davidii) is a promising source of high-quality anthocyanins, with vast potential for application in food, pharmaceutical, and cosmetic industries. However, their availability is limited by resource constraints. Plant cell culture has emerged as a valuable approach for anthocyanin production and serves as an ideal model to investigate the regulation of anthocyanin biosynthesis.

Article Synopsis
  • - The study focuses on improving plantlet regeneration in tissue culture by utilizing iron oxide nanoparticles (FeO-NPs) as a nutrient source in Murashige and Skoog (MS) media to enhance callus formation and control contamination.
  • - The results showed that FeO-NPs significantly increased callus induction and regeneration rates compared to regular MS media, with notable improvements in callus weight, diameter, and root/shoot numbers, indicating a more effective growth environment.
  • - Applying FeO-NPs as a foliar spray led to substantial increases in biomass, height, and chlorophyll content in two rice varieties, while also enhancing enzymatic activities that help plants respond to stress, suggesting that this approach could be beneficial for
