Summary: As a result of the Chornobyl Nuclear Power Plant accident, significant areas were exposed to ionizing radiation, particularly Cs-137, which has long-term impacts on living organisms. This study investigated the effects of increased ionizing radiation on non-enzymatic antioxidants and antioxidant defense enzymes in Helianthus tuberosum L., a plant with high adaptability to abiotic factors. The activity of catalase and peroxidase weakly correlated with radiation exposure, while ascorbate peroxidase activity strongly positively correlated with radiation exposure. Samples from areas with constant low radiation exposure had increased concentrations of ascorbic acid and water-soluble phenolic compounds compared to controls. This study provides insight into the adaptive responses of plants to prolonged exposure to ionizing radiation.

Summary: Salt stress significantly inhibited cell proliferation and decreased relative cellular activity in Jerusalem artichoke suspension cells. Soluble sugar, proline, H2O2, and malondialdehyde content were affected by salt stress. Proteomic analysis revealed a total of 313 upregulated proteins and 365 downregulated proteins after salt stress. These proteins were involved in cell division, water balance reconstruction, ROS scavenging, ribosome and protein biogenesis, and carbohydrate metabolism. Salt stress affects protein synthesis, cell division, and the expression of proteins related to ROS control and metabolic homeostasis in Jerusalem artichoke cell culture.

Summary: This study evaluated the effects of different methods on enzyme inactivation in Jerusalem artichoke pickles, finding that a combination of NaCl and ultrasound showed better results in reducing enzyme activity and maintaining inulin content. Additionally, the dominant microorganisms isolated from the culture were identified as Enterococcus faecalis and the salt-tolerant yeast Meyerozyma guilliermondii.

Summary: This study identified differentially expressed genes in Jerusalem artichoke seedlings under drought stress, analyzed their roles in metabolic pathways, and conducted a transcription factor analysis focusing on NAC, MYB, WRKY, HD-ZIP, and bZIP. The findings suggest that transcription factors may regulate structural genes expression level in metabolic pathways to respond to drought stress and accumulate related metabolites.

Summary: Jerusalem artichokes, a perennial crop with high drought tolerance and value, have been studied for their metabolomic response to drought stress using ultra-performance liquid chromatography and tandem mass spectrometry. The study identified differential metabolites involved in secondary metabolism and amino acid biosynthesis, providing insights for breeding drought-resistant varieties.

Summary: The co-inoculation of arbuscular mycorrhizal fungus (AMF) and phosphate solubilizing bacteria (PSB) was found to promote the growth and production of sunchoke, with PSB positively affecting AMF spore density and colonization rate. The effects varied in different years due to varying environmental conditions.

Summary: The combination of phosphate solubilizing bacteria (PSB) and arbuscular mycorrhizal fungi (AMF) can enhance the growth and yield of sunchoke. Co-inoculated sunchoke plants with AMF and PSB showed the best performance, with increased chlorophyll concentration, root growth, and yield. This study is significant for developing biological inoculants to improve sunchoke growth and production under drought conditions.

Summary: This study analyzed the transcriptome of Jerusalem artichoke under salt stress and found that plant hormone signal transduction plays a crucial role in its response to salt stress. The expression patterns of genes related to abscisic acid, auxin, ethylene, and jasmonic acid underwent significant changes.

Summary: This study compared and evaluated the drought resistance of four Chinese oak species, Q. fabri, Q. serrata, Q. acutissima, and Q. variabilis, at the seedling stage. The results showed that all four oak species exhibited a downward trend in physiological indicators under drought stress, followed by an upward trend after rehydration. The comprehensive evaluation indicated that Q. serrata had the highest drought resistance, while Q. acutissima had the lowest.

Summary: This study investigated the inulinase production capability of Galactomyces geotrichum TS61 using Jerusalem artichoke as a substrate and optimized the fermentation process using Taguchi design. The effects of sucrose on inulinase production were also studied. After optimization, the inulinase activity increased by approximately 8-fold.

Summary: In this study, the usage of dried Jerusalem artichoke tubers powder (DJATP) in cheese manufacturing was evaluated. DJATP exhibited high water holding, oil absorption, and swelling capacities. It supported probiotic bacterial growth and accelerated milk fermentation. The addition of DJATP increased the cheese yield and improved the sensory features and probiotic activity.

Summary: The study found that extracts from Helianthus salicifolius and Helianthus tuberosus aerial parts exhibited antimicrobial activity against bacteria and yeasts, with the tuberosus extract showing higher antioxidant activity. The potential application of these extracts as natural antioxidants with biocidal activity, as well as natural preservatives in cosmetics and food, was suggested based on the obtained data.
