Hormonal Regulation of Plant Development and Stress Tolerance

Dear Colleagues,

Hormonal regulation plays a critical role in the complex processes of plant development and stress tolerance. Plants rely on a sophisticated network of hormones that coordinate growth, flowering, fruiting, and their responses to various environmental stresses. These hormones, including auxins, gibberellins, cytokinins, abscisic acid, and ethylene, act as chemical messengers, transmitting signals throughout the plant's tissues and organs. Each hormone has specific functions and influences different aspects of plant development, such as cell division, elongation, differentiation, and senescence. Moreover, these hormones are intricately involved in the plant's ability to cope with abiotic and biotic stresses, such as drought, salinity, pathogens, and temperature fluctuations. By modulating hormone levels and signaling pathways, plants can adapt and respond to stressful conditions. Understanding the intricate hormonal regulation of plant development and stress tolerance is not only vital for advancing our awareness of plant biology, but also holds significant potential for improving crop productivity and resilience in the face of environmental challenges. The topics of the papers can cover, but are not limited to, the following:

• The hormonal regulation of plant development at various stages of growth (such seed germination, flowering, fruit development and ripening, leaf senescence, and others);
• The impact of hormones on abiotic and biotic stress tolerance;
• Hormone signaling and biosynthesis in plants;
• The genetic modification of plants to alter their hormonal responses.

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. 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.
