Phytohormones in Vegetable Reproductive Development under Abiotic Stress

Dear Colleagues,

Crop growth and productivity are adversely affected by various abiotic stresses. Crop plants are frequently exposed to a plethora of stress, such as low temperature, salt, drought, flooding, heat, oxidative stress, and others. Abiotic stress prevents crops, in general, and vegetable crops, in particular, from reaching their yield potential, becoming the primary threat to agriculture production.

Hormones are signaling molecules that participate in the control of plant growth and development. Recent research demonstrates that female and male flower organs and gametophytes’ developmental processes are under hormonal regulation. Recent work has also shown that plant hormones play a central role in the perception and mitigation of abiotic stress in plants. However, these findings are mainly in the model plant Arabidopsis and other model crops. Over the recent years, our understanding of cellular hormone homeostasis and hormone signaling-related molecular mechanisms has massively improved. However, we are still far from having a comprehensive picture of phytohormones’ complex molecular interactions in the reproductive developmental process of vegetable crops. Furthermore, we still lack an understanding of the role of phytohormones during reproductive development, gametogenesis, and embryogenesis under abiotic stress conditions.

This Special Issue calls for original research articles, reviews, and perspectives that address the progress and current knowledge in the study on the role of phytohormones in the reproductive development of vegetable crops under abiotic stress conditions. The Special Issue will focus on understanding the role of plant hormones in the following reproductive process: stamen and carpel development, gametogenesis (female and male), pollination, pollen pistil interaction, fertilization, embryogenesis, fruit development, and other related processes.

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.
