Special Issue Information
Dear Colleagues,
Plants perceive and react to abiotic and biotic factors prevailing in their growth environment. In the presence of metal ions, reactive oxygen species (ROS) prompt the peroxidation of membrane lipids, which generate α,β-unsaturated aldehydes. These aldehydes are reactive electrophile species (RES), which then form carbonyl adducts on proteins in a non-enzymatic process termed protein carbonylation. Carbonylated proteins have been found at all stages of plant life cycle, but compared to animal models, little is known about the role of protein carbonylation in plant redox biology, growth, and development. The non-enzymatic feature of the carbonylation reaction has slowed efforts to identify functions regulated by protein carbonylation in plants. Nevertheless, a few studies on seeds have pointed to a role of protein carbonylation in diverse plant physiological processes. Exogenous application of α,β-unsaturated aldehydes was found to trigger the expression of several genes implicated in growth and defense response in humans, animal models, and plants, but the mechanisms of signal transduction by aldehydes in vivo are currently unknown in plants. This Special Issue of Plants will highlight the importance of protein carbonylation in signal transduction by ROS or RES, protein homeostasis, plant physiology, stress response, growth, development, and senescence.

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.
