Special Issue Information

Dear Colleagues,

Metalloids are trace elements possessing shared properties between metals and non-metals. Metalloids include boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te). Members of metalloids are essential and beneficial, as well as highly toxic to several species. Boron is an essential element for the normal growth of most living organisms, such as microbes, plants, and animals. In this regard, considerable efforts have been made to elucidate the role of B in the biological systems as compared to any other metalloids. Similarly, Si is the second most abundant element on the earth's crust, and has been proven to have beneficial effects for plants as well as animals. In plants, Si has been proposed as a fertilizer, considering its prophylactic effects, particularly observed under stress conditions. More than thousands of reports showed improved resilience in plants with Si supplementation under stress conditions. Meanwhile, in animals, Si is being used to prevent bone diseases. Silicon supplementation has been found to be helpful to maintain bone health and recommended as a tonic to avoid bone fractures in elderly people. Besides having plenty of reports, very little is known about the precise role of Si in cellular processes. In plants, Si and As share a common path to be taken up by the roots, which imposes a significant risk to the entire food chain. This is because As is highly toxic and carcinogenic. The area affected by As contamination is continuously growing in different parts of the world. Equally, the rest of the metalloids have also had a significant role in biological systems. These metalloids form several different metallo-organic compounds with distinct properties and functions. In this regard, it is a prerequisite to understand the detailed role of different metalloids, their transport, sequestration, deposition, and speciation in the living systems. This Special Issue of Biomolecules will highlight the present understanding and knowledge gaps in the role of metalloids and metallo-organic compounds in the biological systems.

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. Biomolecules 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 2700 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.

Silicon (Si), despite being abundant in nature, is still not considered a necessary element for plants. Si supplementation in plants has been extensively studied over the last two decades, and the role of Si in alleviating biotic and abiotic stress has been well documented. Owing to the noncorrosive nature and sustainability of elemental Si, Si fertilization in agricultural practices has gained more attention. In this review, we provide an overview of different smart fertilizer types, application of Si fertilizers in agriculture, availability of Si fertilizers, and experiments conducted in greenhouses, growth chambers, and open fields. We also discuss the prospects of promoting Si as a smart fertilizer among farmers and the research community for sustainable agriculture and yield improvement. Literature review and empirical studies have suggested that the application of Si-based fertilizers is expected to increase in the future. With the potential of nanotechnology, new nanoSi (NSi) fertilizer applications may further increase the use and efficiency of Si fertilizers. However, the general awareness and scientific investigation of NSi need to be thoughtfully considered. Thus, we believe this review can provide insight for further research into Si fertilizers as well as promote Si as a smart fertilizer for sustainability and crop improvement. Full article
