Abstract

Background: Jujube (Zizyphus jujuba), belonging to the Rhamnaceae, contains various bioactive components including flavonoids and polysaccharides. In our previous study, jujube quality was improved by application of nano-selenium (Nano-Se) and melatonin; however, little research has been conducted on the induced molecular mechanisms. Zizyphus jujuba cv. Huizao was used as experimental materials to compare and analyze the transcriptomics and metabolomics mechanisms.

Results: Compared with the control, 305, 422, and 240 metabolites and 24, 281, and 44 genes were significantly changed at the metabolic and transcriptional levels in Nano-Se, melatonin, and Nano-Se with melatonin treatments, respectively. The metabolomics indicated that the differentially expressed metabolites were involved in phenylpropanoid biosynthesis, fructose, and mannose metabolic pathways. The Nano-Se with melatonin treatment group increased the contents of glucose and total Se by 1.8 and 5.4 times, respectively. Transcriptomics showed that differentially expressed genes of Nano-Se and melatonin treatment were mainly enriched in phenylpropanoid biosynthesis, pentose, and glucuronate interconversions pathways. In addition, several transcription factors from the NAC, WRKY, MYB, and WRKY families were identified in melatonin versus control and melatonin versus Nano-Se. Furthermore, combined transcriptomic and metabolomic analysis showed that phenylpropanoid biosynthesis, starch and sucrose metabolism, the mutual conversion pathway of pentose, and glucuronate interconversions were the vital pathways in response to Nano-Se and melatonin treatment.

Conclusion: Overall, these results provide new insights into jujube response to Nano-Se and melatonin, and improve our understanding of the jujube molecular mechanisms induced by Nano-Se and melatonin. © 2025 Society of Chemical Industry.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
