Mechanism of Phytohormones Regulating Crop Root Development and Stress Tolerance

Dear Colleagues,

Global climate change is increasing the frequency and severity of stress, thus threatening food production around the world. Plants have evolved to cope with these stresses by triggering growth and development changes, and phytohormones act as all-encompassing regulators in this process. As the belowground organ of the plant, roots are fundamentally important for growth and development as they anchor the plant to its growth substrate, facilitate water and nutrient uptake from the soil, and sense and respond to environmental signals such as biotic and abiotic stresses. Upon exposure to stress, roots change their architecture to help plants survive under stressful conditions. Thus, root plasticity is a good model for studying plant response to stressful environments, and more and more scientists believe that modulating root growth and development provides a potentially useful approach to improve plant stress tolerance without yield penalties. Research on phytohormones in plant root development and stress tolerance has been intensively carried out. This Special Issue of Plants aims to bring together inspiration from multiple research studies and highlight the function of phytohormones in crop root development and stress tolerance.

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 250 words) can be sent to the Editorial Office for assessment.

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.
