Summary: Ginsenosides have been widely studied for their medicinal benefits and their role in ginseng plant biology. They play a crucial role in ginseng's defense against biotic stresses, providing antimicrobial, antifeedant, and allelopathic activities. Ginsenosides also have roles in ginseng development and abiotic stress tolerance.

Summary: Plants have the ability to regenerate from various types of cells, but somatic cell totipotency can be compromised by somaclonal variation, particularly karyotype alteration, during tissue culture. Chinese ginseng exhibits little decline in totipotency and remarkable chromosomal stability even after prolonged tissue cultures. However, it is uncertain whether chromosomal stability at the molecular level necessarily correlates with genetic stability at the nucleotide sequence level.

Summary: This study analysed the diversity and abundance of endophytic microbes in different organs of Panax ginseng using high-throughput sequencing. The results showed that the composition of endophytic microbes varied among the roots, stems, and leaves, with different dominant bacterial and fungal genera. The roots had the highest diversity of endophytic bacteria, while the stems had a higher abundance of Ochrobactrum bacteria and Coniothyrium and Cladosporium fungi. The study provides important insights into the endophytic microorganisms in ginseng.

The total estimated extant fungal diversity is 6.28 million taxa, with Ascomycota and Basidiomycota dominating. Soil and litter have the highest alpha diversity of fungi, while lichens and plant tissues have the highest proportion of unknown species.

Summary: The evolution of sequencing technology and multiplexing has expanded our ability to characterize fungal diversity. However, obtaining an unbiased assessment of the fungal community remains challenging. This study found that shorter amplicons had higher sequencing depths and overall diversity, with no significant bias in phylogenetic composition. Despite the increased resolution of longer amplicons, the shorter amplicons provided clearer resolution of the fungal community. The choice of ribosomal amplicons should be carefully evaluated and adjusted according to specific goals.

Summary: This text discusses the inherent limitations of using the rDNA Internal Transcribed Spacer (ITS) region as a DNA barcode marker in fungal ecology studies. It highlights the challenges in species delimitation, the lack of significant interspecific divergence, and the uncertainty in species-level taxonomy. It also emphasizes the complexity and variation introduced by PCR and sequencing errors in DNA metabarcoding data. The importance of the ITS region as a general DNA (meta)barcoding marker for fungi is acknowledged but caution against naïve or simplistic use is stressed.

Summary: The endosphere of ginseng contains a variety of fungal, bacterial, archaeal and viral endophytes. Bacterial endophytes are primarily members of the Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes, and fungal endophytes are primarily members of the Ascomycota, Zygomycota and Basidiomycota. Little is known about archaea and viruses in ginseng plants. Root tissues have been found to have the highest abundance and diversity of bacterial and fungal endophytes, and their abundance often increases with root age. The metabolization of ginsenosides by endophytes suggests an adaptation of these microbes to the unique secondary metabolites found in ginseng tissues. Research on the benefits provided by endophytes has mainly focused on plant nutrition, growth promotion and disease resistance, with little emphasis on their ability to increase abiotic stress resistance. More studies are needed in the field, including trials with endophyte-treated plants, genomic/metagenomic analysis of endophytes, and investigations into the effects of endophytes on disease resistance and abiotic stress tolerance.

Summary: This study addresses the taxonomic delimitation issue in the Monostroma and Gayralia genera of monostromatic green algae using morphology and DNA analysis. The findings suggest that the genetic distance between Monostroma and Gayralia is smaller than the genetic distance within the Monostroma genus. The specimens share similar morphology but differ in thallus thickness and size.

Summary: The study found that radish mosaic virus isolates from different regions in Korea have distinct sequences and pathogenicity, causing different symptoms in tobacco and radish plants. The accumulation of RNA2 is correlated with the necrosis-inducing ability of the virus, and its level mostly depends on the origin of RNA1. Recombination and reassortment events have played important roles in the evolution of the virus isolates. Additionally, the Korean isolates were found to also infect Chinese cabbage, posing a threat to the crop and causing potential economic losses.

Summary: By studying the infectivity of turnip mosaic virus in different cultivars of Chinese cabbage, it was found that the C-terminal portion of the polyprotein determines the systemic infection of Chinese cabbage. Additionally, the study also revealed that effective R genes against the virus may exist in certain cultivars, and at least one amino acid substitution in the VPg and CP is essential for the infection on Chinese cabbage.

Summary: To address the issue of melamine and cyanuric acid added to pet food, a nondestructive sensing technique using Fourier transform infrared (FT-IR) spectroscopy and machine learning was developed. The 1D CNN model applied to FT-IR spectra achieved superior performance compared to PLSR and PCR models in predicting melamine and cyanuric acid concentrations. Hence, FT-IR spectroscopy with a 1D CNN model serves as a potentially rapid and nondestructive method for identifying toxic chemicals in pet food.

Summary: In this study, a simple birefringence measurement system for Hg2Br2 crystal at the millimeter scale was developed based on Brewster's angle. The system can measure the reflected light intensity of the crystal and calculate the ordinary and extraordinary refractive indices and birefringence. The calculated birefringence of the Hg2Br2 crystal showed a 0.64% error compared to the literature value, indicating the potential for evaluating the quality of birefringent single crystals.

Summary: Chlorophyll fluorescence imaging (CFI) is the latest method used to measure the efficiency of photosynthesis in strawberry plants, providing non-destructive spatiotemporal data. A CFI system was developed in this study to measure the maximum quantum efficiency of photochemistry (Fv/Fm), using a dark adaptation chamber, blue LED light sources, and a monochrome camera with a lens filter. The Fv/Fm values obtained from different treatment groups showed a correlation with a chlorophyll meter, indicating the accuracy of the developed CFI system in capturing the response of strawberry plants to abiotic stresses.

Summary: Foreign materials in fresh-cut vegetables are a major concern for the industry, and effective detection methods are urgently needed. This study investigated three hyperspectral imaging techniques to distinguish foreign materials in fresh-cut vegetables, and a discriminant analysis model was developed. The SWIR hyperspectral imaging system provided the best detection accuracy, followed by VNIR and fluorescence. The results suggested that the SWIR hyperspectral imaging techniques with the SPA-PLS-DA model could be efficiently used in industrial applications for rapid and nondestructive foreign materials detection in fresh-cut vegetables.

Summary: Conventional spectroscopic methods such as IR and Raman lack effectiveness in detecting low levels of pesticides or harmful chemicals in food. This study presents a highly sensitive and uniform wafer-scale Au nanogap SERS substrate for quantitative analysis of carbaryl pesticide levels in different food samples. The substrate was able to detect carbaryl up to 3 ppb in concentration with low LOD values. The combination of VIP method and PLSR achieved high predictive accuracy and differentiation ability for different concentrations and adulteration of carbaryl in food samples.
