Special Issue "The Role of Growth Regulators in Crop under Abiotic Stress"
Deadline for manuscript submissions: closed (30 September 2020) | Viewed by 9094
In addition to developmental processes, endogenous plant hormones play crucial roles in the response to biotic and abiotic stresses. Phytohormones (auxins, brassinosteroids, cytokinins, ethylene, gibberellins, jasmonates, abscisic, and salicylic acids) are the key mediators of plant responses to various abiotic stress. However, these hormones usually engage in crosstalk with each other to increase the survival of plants. It has been shown that the direct application of such hormones to plant roots, shoots, leaves, buds and flowers increases resistance to abiotic and biotic stress. Phytohormones can improve drought tolerance and water use efficiency, improve temperature tolerance, improve nitrogen use efficiency, promote shoot elongation and generation, stimulate root growth and lateral root development, and promote photosynthesis. The use of phytohormones or their synthetic derivatives on crops can improve yields in fields affected by global climate change. Recently, great efforts have been devoted to understanding the phytohormone regulatory mechanisms in plant response to various stresses; however, many questions still remain unanswered. This Special Issue is focused on introducing the latest interesting findings on the roles of phytohormones and their crosstalk in the abiotic stress adaptation of major crops. We therefore invite submissions on topics including, but not limited to, the following: (1) the effect of plant hormones on the growth and development of crops; (2) the use of plant hormone derivatives as biostimulants to increase yields; (3) phytohormonal profiling during stress conditions; (4) phytohormonal crosstalk as a response to abiotic stresses.

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. Agronomy 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 2000 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.
