“…The region's food and pharmaceutical sectors greatly benefit from this species owing to the rich assortment of bioactive compounds found in its fruits, including vitamin C, amino acids, flavonoids, and terpenoids [1-3]. These compounds exhibit notable pharmacological effects, encompassing antibacterial, anti-aging, anti-apoptotic, antioxidant, and anti-atherosclerotic properties [4][5][6]. With advancing research, the potential health advantages of R. roxburghii have attracted widespread attention.Currently, Guangzhou Pharmaceutical Group Co., Ltd. has successfully developed various products from the fruit of R. roxburghii, including juice, vinegar, jam, and cakes, etc., which generate considerable economic benefits with sales exceeding RMB 100 million [6].…”

Rose roxburghii, a horticulturally significant species within the Rosa genus of the Rosaceae family, is renowned for its abundance of secondary metabolites and ascorbate, earning it the title ‘king of vitamin C’. Despite this recognition, the mechanisms underlying the biosynthesis and regulation of triterpenoid compounds in R. roxburghii remain largely unresolved. In this study, we conducted high-performance liquid chromatography profiling across various organs of R. roxburghii, including fruit, root, stem, and leaves, revealing distinct distributions of triterpenoid compounds among different plant parts. Notably, the fruit exhibited the highest total triterpenoid content, followed by root and stem, with leaf containing the lowest levels, with leaf containing the lowest levels. Transcriptomic analysis unveiled preferential expression of members from the cytochrome P450 (CYP) and glycosyltransferase (UGT) families, likely contributing to the higher accumulation of both ascorbate and triterpenoid compounds in the fruits of R. roxburghii compared to other tissues of R. roxburghii. Transcriptomic analysis unveiled a potential gene network implicated in the biosynthesis of both ascorbate and triterpenoid compounds in R. roxburghii. These findings not only deepen our understanding of the metabolic pathways in this species but also have implications for the design of functional foods enriched with ascorbate and triterpenoids in R. roxburghii.
