Special Issue Information
Dear Colleagues,
Crop plants are exposed to various biotic and abiotic stresses. Oxidative stress results in damage to cell organelles and the cell membrane, which can ultimately lead to cell death. These processes occur due to the overproduction and accumulation of highly toxic reactive oxygen species (ROS), most often as a result of an imbalance between the production of ROS and the activity of scavengers. Consequently, metabolism is disrupted, leading to a weakening of the plants, consequently affecting their productivity. Nowadays, in plant cultivation, the aim is to reduce the use of chemicals (fertilizers and pesticides) and look for environmentally friendly products to promote their growth and development and increase productivity. One of the solutions aimed at providing plants with the most favorable conditions for growth and development is using biostimulators, which are an alternative to synthetic fertilizers and plant protection products. Biostimulants can be made from seaweeds, humic substances, protein hydrolysates, and microorganisms. In addition, there is an increasing emphasis on producing agents that exhibit low toxicity to humans and animals. Biostimulation has a regulating and modifying effect on the course of physiological processes occurring in plants. They also stimulate their growth and alleviate disorders caused by environmental stresses to which plants are exposed. Biostimulation affects the basic processes and defense mechanisms in plants, enabling them to maintain homeostasis to ensure their adaptation to changing environmental conditions. This makes them safer for the environment and contributes to sustainable crop production. The current Special Issue aims to gather both original and review articles that describe recent advances in the use of biostimulants in crop plants exposed to oxidative stress.
Potential topics include, but are not limited to, the following:
- Negative effects of environmental stresses on crops;
- Mechanism of action of biostimulants in plant cultivation;
- Alleviating the effects of stress.

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. Antioxidants 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 2900 CHF (Swiss Francs).
