Special Issue Information
Dear Colleagues,
During the pandemic caused by the coronavirus, many people believed that pandemics were the most serious problems for humanity. However, what has still not been solved is the issue of food scarcity. Even today, most deaths worldwide are caused by malnutrition, and this cannot be solved with vaccines. Currently, the death rate from malnutrition is estimated to be more than 10 people every minute; therefore, continued fast increases in crop yields are required to feed the growing world population. Although the yields of many crop plants showed increasing trends in recent decades, the yields of the key crops have reached a plateau in recent years. Due to the abiotic stresses on plants (temperature stresses, drought, toxic metals, etc.), a global crop loss of almost 50-70% is expected. It is true that the cultivation area of some crop plants is also shifting towards the previously colder areas; climate change in most places is accompanied by increasing drought periods, an increase in the proportion of areas with high salinity, and the appearance of temperature extremes in an increasingly frequent and severe form. In addition to all this, climate change also increases the spread of pathogens, and pests are also appearing in more and more places. A significant part of the stress symptoms occurring in plants can be attributed to oxidative stress resulting from the excessive production of reactive oxygen species. Defence against them is especially important. However, results from recent years have shown in several cases that the appearance of some reactive oxygen forms in controlled amounts can have a good effect by serving as a signal for the initiation of some defensive processes. The understanding of these complex processes is still incomplete. In order to develop crop plants that cope with stress with lower damage, a better understanding of the molecular biological background of stress tolerance mechanisms is essential. We expect the papers appearing in this Special Issue to present the latest results related to the protective processes against reactive oxygen species and the operation of the related regulatory systems. Molecular techniques, which may help to detect the reactive oxygen species and the components of the antioxidant systems, are also in the scope of the present Special Issue.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
