Plant Plasticity and Signalling Pathways in Adaptive Responses

Dear Colleagues,

Plants are essential for life on Earth and represent key entities in agriculture as well as in various industrial fields. As sessile organisms, they have had to develop a complex system to dynamically respond to ever-changing environmental conditions. Moreover, they possess a unique feature—the ability to form all organs from a single part of the plant body and adapt the size (and, to a limited extent, also shape) of developing organs. This ability enables adaptation to changing internal or external conditions. The fundamental role in adaptation processes is executed by plant signaling pathways, which sense environmental stimuli, react to them, and subsequently drive morphological and/or physiological changes. Variation in external conditions mainly correspond to abiotic and biotic stresses, while internal changes often reflect an imbalance in cellular homeostasis or developmental programs. Both phytohormone-dependent and independent regulatory pathways mediate plant adaptation. The resulting phenotype changes can be detected by a wide range of approaches, extending from cell biology techniques to field phenotyping. The obtained fundamental knowledge can lead to improvement of important agricultural parameters, such as increase of crop yield or obtaining of more flexible/adaptive crops in environmentally unstable regions.

In this Special Issue, we focus on hormonal and non-hormonal signaling pathways that are responsible for plant adaptive responses and current methods for their characterization.

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 2600 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.
