Special Issue Information

Dear Colleagues,

Drought is viewed as the most common environmental stress, negatively impacting the normal physiology and growth of plants, and it will be a major challenge for agriculture due to global climate change.

Drought results in limited plant growth and development, due to reduced photosynthetic efficiency and then C assimilation, but also due to increased generation of reactive oxygen species (ROS).

However, drought can strongly affect plant nutrient relations. It has been demonstrated that drought can decrease the concentration of most nutrients in plant tissues (including in seeds), both by altering the rate of ecosystem nutrient cycles, thus causing the reduction of nutrient supply through mineralization, and by reducing nutrient diffusion and mass flow in the soil. Moreover, drought stress results in reduced nutrient uptake from the soil. The mechanisms that plants have evolved for nutrient uptake, translocation and assimilation may not optimally function under drought conditions.

On the other hand, nutrients are also helpful to alleviate drought stress. Among adaptive mechanisms developed by plants to cope with drought stress condition, the improvement of the mineral-nutrient status seems to play a critical role. Under drought, plants increase the allocation of resources to roots and the release of root exudates, to favour the uptake of nutrients.

Given the above implications and considering that most vegetable and seed crops are cultivated in semiarid areas and in regions suffering from temporary drought, it is of primary importance to understand how water stress affects the nutrient uptake and assimilation capability of plants, in order to optimize the crop efficiency and sustainability of soil nutrients, to improve the competitiveness and sustainability of agriculture whilst minimizing environmental impacts.

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.
