Summary: An efficient shoot regeneration protocol was developed for Thottea siliquosa via indirect shoot regeneration from root explants. The best callus induction and shoot induction responses were obtained with specific combinations of plant growth regulators. The field established in vitro propagated plants showed higher phytochemical content and antioxidant activity compared to the mother plants and root derived callus.

Summary: Plant cell culture can be manipulated using plant growth regulators to induce metabolic changes for the production of specialized metabolites. This study investigated different combination ratios of PGRs to induce metabolic changes in Bidens pilosa callus, revealing distinct metabolomic profiles dominated by chlorogenic acids. While organogenesis was not achieved, the results demonstrate the potential of using exogenous PGRs to manipulate plant metabolism for in vitro production of specialized metabolites.

Summary: The sweet chestnut fruit is of great importance in southern European countries due to its economic, environmental, and health benefits. This study investigated the antioxidant activity and chemical composition of different varieties of chestnuts grown in various regions of northwest Spain, and found that climate and geographic factors significantly affect the quality and potential of chestnuts.

Summary: This study investigated the effects of different light qualities on the growth of red callus, accumulation of phenolic compounds, and total antioxidant capacity in spine grape. Blue and purple light increased red coloration in the callus, while yellow light promoted the greatest callus proliferation. White, blue, and purple light induced increased anthocyanin accumulation. Mixed-wavelength light was beneficial for flavonoid accumulation. Blue and purple light facilitated the accumulation of proanthocyanidins. The total antioxidant capacity of the callus cultures varied significantly depending on the light quality. These findings provide evidence for using abiotic elicitors to stimulate callus growth and enhance the accumulation of phenolic compounds in the red callus of spine grape.

Summary: The effects of jasmonic acid (JA) and salicylic acid (SA) elicitation on the accumulation of total phenolics and flavonoids and the regulation of antioxidant metabolism in callus cultures of G. moluccana L. were determined in this study. JA treatment resulted in higher levels of total phenolics and flavonoids compared to SA treatment and control. Real-time PCR analysis revealed a correlation between transcriptional and enzyme activity regulation in response to both treatments.

Summary: Echinacea purpurea, a medicinal plant, was treated with fungal elicitors to increase biomass and the levels of phenolics and flavonoids. Different elicitors showed varying effects on callus production and antioxidant activity, with Fusarium oxysporum being the most effective in enhancing the productivity of phenolics and flavonoids. This study highlights the potential of using callus cultures and biotic elicitation for the production of antioxidant compounds from E. purpurea.

Summary: The population of Magnolia lanuginosa, a rare tree species in northeastern India, has significantly declined due to habitat destruction, low natural regeneration, and over-harvesting. This study investigated the dormancy type and the effect of storage on the viability and germination behavior of M. lanuginosa seeds under various physical and chemical treatments. The results provide valuable insights for devising seed germination protocols and reintroducing the species into the wild.

Summary: The study revealed high genetic diversity in Illicium griffithii, with various molecular markers showing high levels of polymorphism. There is a low level of genetic differentiation among populations, with some gene flow observed. Clustering and PCA analysis indicated that genetic material can only mix between populations that are geographically close. The results contribute to the conservation of the population structure and genetic diversity of I. griffithii for effective conservation strategies.
