Abstract

Background: Sweet potato (Ipomoea batatas (L.) Lam.) with high yield and diverse nutrients, is the third most important food crop in the world. Manganese (Mn) is an essential cofactor that plays a critical role in the development and maturation of the crop. However, the molecular mechanism underlying the sweet potato response to Mn remains unclear.

Results: In this study, Mn treatment increased the depth of yellow color in sweet potato, augmented sugar and carotenoid accumulation in storage roots, accompanied with a decline in plant hormones. Especially, Mn-treated storage roots displayed more than a 200% increase in β-carotene content compared to the control, while the abscisic acid (ABA) content was reduced by at least 50%. An integrated metabolomic and transcriptomic analysis suggested that Mn application regulated transcriptional and metabolic profiles of carotenoid biosynthesis, soluble sugar, carbon fixation in photosynthetic organisms and biosynthesis of amino acids. Further study revealed that Mn treatment stimulated β-carotene accumulation in storage roots by up-regulation of the transcripts of GGPPS, ZIDS, LCYB and OR, along with down-regulation of CCD1 and CCD4. Moreover, Mn application reduced ABA content through preventing the expression of NCED1.

Conclusion: Our results indicated that Mn, emerging as an agrochemical candidate, will meet agricultural challenges by not only enriching the flesh coloration but also augmenting the nutritional value of sweet potatoes. © 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.
