Abstract Ginseng (Panax ginseng C. A. Mey.) is an important and valuable medicinal plant species used in traditional Chinese medicine, and its metabolite ginsenoside is the primary active ingredient. The FAR1/FHY3 gene family members play critical roles in plant growth and development as well as participate in a variety of physiological processes, including plant development and signaling of hormones. Studies have indicated that methyl jasmonate treatment of ginseng adventitious roots resulted in a significant increase in the content of protopanaxadiol ginsenosides. Therefore, it is highly significant to screen the FAR1/FHY3 gene family members in ginseng and preliminarily investigate their expression patterns in response to methyl jasmonic acid signaling. In this study, we screened and identified the FAR1/FHY3 family genes in the ginseng transcriptome databases. And then, we analyzed their gene structure and phylogeny, chromosomal localization and expression patterns, and promoter cis-acting elements, and made GO functional annotations on the members of this family. After that, we treated the ginseng adventitious roots with 200 mM methyl jasmonate and investigated the trend of the expression of four genes containing the largest number of methyl jasmonate cis-acting elements at different treatment times. All four genes were able to respond to methyl jasmonate, the most significant change was in the PgFAR40 gene. This study provides data support for subsequent studies of this family member in ginseng and provides experimental reference for subsequent validation of the function of this family member under methyl jasmonic acid signaling.

- Abstract
Saponins, the major bioactive components of Panax ginseng C. A. Mey., are gradually emerging as research hotspots owing to the possession of various pharmacological activities. This review updates the ginsenosides list from P. ginseng and the steam-processed ginseng (red ginseng and black ginseng) up to 271 by June of 2024, encompassing 243 saponins from different parts of P. ginseng (roots, stems, leaves, flowers, berries, and seeds), 103 from red ginseng, and 65 from black ginseng, respectively. Among 271 saponins, there are a total of 249 ( 1 - 249 ) dammarane type (with a - z subtypes) tetracyclic triterpene saponins reported from each part of P. ginseng and steam-processed ginseng, two ( 250 - 251 ) lanostane type tetracyclic triterpene saponins identified from red ginseng, 18 ( 252 - 269 ) oleanane type pentacyclic triterpenoid saponins discovered from each part of P. ginseng and steam-processed ginseng, and two ( 270 - 271 ) ursane type pentacyclic triterpenoid saponins reported from red ginseng. Overall, this review expounds on the chemical diversity of ginsenosides in various aspects, such as chemical structure, spatial distribution and subtype comparison, processed products, and transformation. This facilitates more in-depth research on ginsenosides and contributes to the future development of ginseng., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 Tianjin Press of Chinese Herbal Medicines.

Panax ginseng C. A. Mey., a perennial herb belonging to the family Araliaceae, is a valuable medicinal plant with distinctive biological characteristics. However, comprehensive analyses of the mitochondrial genome (mitogenome) are lacking. In this study, we sequenced the complete mitogenome of ginseng based on long-read data from the Nanopore sequencing platform. The mitogenome was assembled into a “master circle” form of 464,705 bp and contained 72 unique genes. The genome had three large repeat regions, and 10.42% of the sequences were mitogenome sequences of plastid origin (MTPTs). In total, 278 variants (213 SNPs and 65 InDels) were discovered, most of which were identified in intergenic regions. The MTPT regions were mutational hotspots, harboring 74.5% of the variants. The ginseng mitogenome showed a higher mutation rate than that of the chloroplast genome, and this pattern is uncommon in plants. In addition, 10 Kompetitive allele-specific PCR (KASP) markers were developed from 10 SNPs, excluding those in MTPT regions. These markers accurately identified the genotypes of 59 Korean ginseng accessions and elucidated mitogenome diversity. These results provide insight into organellar genomes and genetic diversity in ginseng. Moreover, the complete mitogenome sequence and 10 KASP markers will be useful for ginseng research and breeding.
