Special Issue Information

Dear Colleagues,

As sessile organisms, plants must constantly adjust their growth and architecture to their ever-changing environment. In doing so, they need to evolve mechanisms mediated by signaling molecules that ensure the correct integration of environmental stimuli with endogenous developmental programs. Some of the effective chemical messengers are plant hormones, which play an impressive range of roles during normal plant growth and development from embryogenesis to senescence, as well as in various responses to both biotic and abiotic stresses.

This Special Issue focuses on revealing the recent advances in all aspects of phytohormones’ modes of action—from perception and signal transduction to homeostasis and their influence on gene expression. It also covers the mechanisms of phytohormone cross-talk with other molecules involving their synergy and interdependency, whose interactions converge at physiological, biochemical, molecular, and structural levels integrating and coordinating the developmental processes under normal and stressful conditions. Further, our Special Issue concerns the intercellular transport of plant growth regulators and their function in systemic signaling systems by which plants induce and maintain protection against various stressors.

We welcome the submission of original and review papers contributing to a better understanding of plant hormones sensu lato and showing the current state of knowledge and future prospects in this scientific research area.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

The mesocotyl is of great significance in seedling emergence and in responding to biotic and abiotic stress in maize. The NAM, ATAF, and CUC2 (NAC) transcription factor family plays an important role in maize growth and development; however, its function in the elongation of the maize mesocotyl is still unclear. In this study, we found that the mesocotyl length in zmnac17 loss-of-function mutants was lower than that in the B73 wild type. By using transcriptomic sequencing technology, we identified 444 differentially expressed genes (DEGs) between zmnac17-1 and B73, which were mainly enriched in the “tryptophan metabolism” and “antioxidant activity” pathways. Compared with the control, the zmnac17-1 mutants exhibited a decrease in the content of indole acetic acid (IAA) and an increase in the content of reactive oxygen species (ROS). Our results provide preliminary evidence that ZmNAC17 regulates the elongation of the maize mesocotyl. Full article
