Effect of Nutrient Deficiencies on Stress Tolerance of Plants and Its Mechanism

Dear Colleagues,

To cope with nutrient scarcity, plants generally follow two main complementary strategies. On the one hand, they can slow down growth, mainly shoot growth, to diminish the demand of nutrients. It is known that the TOR (Target Of Rapamycin) system is a central regulator of growth in response to nutrients in eukaryotic cells. On the other hand, plants can develop different physiological and morphological responses, mainly in their roots, aimed to facilitate the acquisition of nutrients. It is known that the plant hormone ethylene participates in the activation of many nutrient deficiency responses.
Both strategies are compatible and can function simultaneously, but the interconnection between them is not yet well known.
Papers submitted to this Special Issue must report new results and the latest findings related to the interconnection between both strategies. We particularly welcome manuscripts dealing with the following topics:

• New advances and methods for the determination of both the “stop growing” and “searching for nutrients” strategies aimed at achieving greater stress tolerance of plants.
• New research shedding light on the relationship of ethylene with the TOR system related to the control of plant growth and development of nutrient deficiency responses.

All forms of submissions (i.e., original research papers, mini reviews, methods, perspectives, hypotheses and theories, and opinion articles) are welcome.

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-anonymized 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 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 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.
