Special Issue Information

Dear Colleagues,

Biofortification has become a key strategy for enhancing the nutritional and functional value of horticultural crops, contributing to food security, sustainability, and human health. While agronomic biofortification through the application of mineral fertilizers and biostimulants offers a practical method for improving micronutrient content and crop performance, conventional breeding and genome editing (e.g., CRISPR/Cas) are expanding opportunities to achieve more targeted and durable enhancements.

This Special Issue focuses on biofortification strategies which use either agronomic, genetic, biotechnological tools, or a combination thereof to improve yield, resilience and the accumulation of health-promoting compounds in horticultural crops. We welcome original research and reviews addressing nutrient dynamics, soil–plant interactions, genotype × environment × management (G × E × M) interactions, and innovative fertilization or genome-based techniques. Potential topics may include enhancement of micronutrients and phytochemicals, metabolic and transcriptional responses, improvement of postharvest quality, and contributions to the development of functional foods.

Interdisciplinary contributions that link plant nutrition, physiology, breeding, molecular biology, and food science are of particular interest. By highlighting both scientific advances and practical applications, this Special Issue aims to provide a comprehensive view of current advances in biofortification and foster new insights for the development of nutrient-enriched horticultural crops adapted to future agricultural and nutritional challenges.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Agronomy is an international peer-reviewed open access semimonthly journal published by MDPI.

Calcium (Ca) and selenium (Se) are garnering growing interest because of their capacity to boost crop yields and minimize cadmium (Cd) concentration within edible parts. However, whether Ca and Se can synergistically inhibit Cd accumulation in crops and its mechanism remains poorly understood. A hydroponic experiment was conducted under Cd exposure with the combined supplementation of Ca and Se, specifically focused on Cd accumulation and its mechanism. The results revealed that Ca and Se synergistically enhanced growth and photosynthetic content, whereas they inhibited Cd accumulation in the roots, stems, and leaves of peppers. Ca and Se also synergistically reduced the content of Cd in the cell wall, organelle fraction, and soluble fraction of the roots, as well as in pectin, hemicellulose I, hemicellulose II, and cellulose. Ca and Se supplementation synergistically downregulated the expression levels of CaNramp1, CaNramp5, CaHMA1, and CaHMA2. These results revealed that Ca and Se synergistically reduced Cd accumulation in peppers by modulating targeted gene downregulation involved in Cd absorption and translocation. Full article
