Special Issue Information

Dear Colleagues,

Plants have evolved highly effective uptake and transport systems with which to ensure the acquisition and allocation of optimal levels of essential mineral nutrients for growth and development. Meanwhile, plants inevitably take up and accumulate nonessential toxic trace elements in eatable parts which may enter food chains and eventually treaten human health. This Special Issue, entitled “Novel Studies on the Uptake, Transport and Accumulation of Mineral Nutrients and Trace Elements in Crops”, aims to offer an insight into the physological and molecular mechanisms underlying the uptake, transport, and accumulation of mineral nutrients and trace elements in crops. These include, but are not limited to, the following: (i) uptake and transport of various macroelements and their use efficiencies; (ii) accumulation and detoxification of microelements, particular those nonessential toxic trace elements; (iii) accumulation and biofortification of essential mineral nutrients in crops; and (iv) novel technologies in quantifying and visualizing various elements. We welcome the submission of original research articles as well as reviews on the above topics. Contributions on the genetic and molecular mechanisms of the uptake, transport, and accumulation of mineral nutrients and trace elements in crops are particularly encouraged.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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 monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Calcium (Ca) and Boron (B) are structural components of the cell wall with limited phloem mobility. The absorption, movement, and distribution of these two nutrients have a greater effect on leaves than on fruits since their transport is dependent on transpiration flow. This research aimed to study the absorption and movement of 45Ca applied to the soil and the fruit of sweet cherry trees under B-deficient and B-adequate soil conditions. In the first experiment, 45Ca was applied to the soil surface before the occurrence of leaf senescence. Soil and tree components were sampled and analyzed 6 months after 45Ca application. The second experiment involved a 45Ca application to the surface of small fruits with 5 mm diameters, which were analyzed after 45 days. The tree Ca allocation in the B-deficient soil condition was significantly fewer in shoots and higher in roots, contrary to the B-adequate soil. On the other hand, the fruit evidenced significant differences in Ca levels in the edible portion of the fruit (i.e., the flesh and peel), which was higher in the B-adequate soil condition. Therefore, under B-deficient soil, Ca was ‘retained’ in the root system and in the fruit pit, suggesting a synergistic mechanism between Ca and B. This mechanism might indicate a survival ecological function where B triggers biological signals to restore Ca homeostasis. Full article

Iodine is a critical trace element necessary for human and animal health owing to its role in thyroid hormone synthesis. Despite its importance, iodine deficiency remains a global health concern. Traditional methods to address this issue, such as salt iodization, face challenges like iodine loss during storage and cooking. The biofortification of plants, particularly carrots, offers a promising alternative. This study investigates iodine accumulation and distribution in carrots biofortified with potassium iodide (KI) and potassium iodate (KIO3) using single extraction at elevated temperatures with tetramethylammonium hydroxide followed by iodine determination by ICP-MS. Results show that iodine biofortification significantly increases the iodine content of various parts of the carrot, especially the leaves and the root peels. Carrots treated with iodate accumulate 2.7 times more iodine than those treated with iodide. The leaves exhibit the highest iodine content, particularly in iodate-treated plants, where levels can be over 24 times higher than those of control carrots. Root peel and roots also accumulate substantial amounts of iodine, with the iodate treatment resulting in 5.42 mg·kg−1 and 3.75 mg·kg−1 dry weight, respectively. The potential application of biofortified carrots can help meet human dietary iodine requirements; additionally, iodine-rich carrot leaves as livestock feed offer a sustainable approach to increasing the iodine intake in animals.
