Physiological Changes in Plants Species Submitted to High Levels of Micro and Macronutrients

Dear Colleagues,

Plants absorb nutrients through their roots from the soil that are transported through the stem to the different areas of the plant that are above ground level. Macronutrients, as the name suggests, are the nutrients required by plants in large amounts. These include carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, calcium and potassium. Micronutrients are required in small amounts by plants. These include iron, zinc, boron, etc. In addition to these, some elements such as silicon, cobalt, selenium and sodium are present, which are required by higher plants. Managing crop nutrition by applying macro- and micronutrients is important for obtaining high yields and ensuring the quality of the consumed products.

The deficiency of any of these nutrients may lead to defects in plant growth and decreased productivity. There is a lot of research focusing on the role of micro- and macronutrients in plant growth and the consequences of deficiency. However, for some micronutrients, the concentration in the soil can be too high and result in toxicity. Some plants respond to nutrient toxicity by increasing nutrient efflux and activating detoxifying pathways; whereas, others can tolerate high concentrations of certain micronutrients because they have developed systems to store these and utilize them for defensive functions.

This Special Issue of Plants will analyze, from a multidisciplinary approach (ecophysiology, metabolomics, proteomics, transcriptomics, etc.), the impact of a high level of micro- and macronutrients on plant performance and crop quality.

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. Plants is an international peer-reviewed open access semimonthly 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.
