Endoplasmic Reticulum Stress Response in Plants under Changeable Environment

Dear Colleagues,

Higher plants are sessile in their habitats; they adapt their growth and development according to the changing environment. In elucidating various stress responses at the molecular level, the organellar homeostasis is revealed to be essential for organismic survival under adverse conditions. Among these organelles, endoplasmic reticulum (ER) plays a crucial role in regulating secretory protein synthesis and maturation, while accumulating un-/mis-folded proteins overwhelm the ER folding capacity and therefore cause cellular dysfunction and death.

Previous studies on protein quality control in plant ER reveals a systemized transcriptional program to reduce translating mRNA and increase the protein folding capacity in model plants. Recently, the field of stress biology of plant ER has shifted its focus on to how does ER stress response function under non-stress conditions to support plant growth and how ER stress response restores ER homeostasis under ambient environments.

This Special Issue on the endoplasmic reticulum stress response of plants in changing environments aims to gather recent advances in the understanding of molecular mechanisms to cope with the accumulation of unfolded/misfolded proteins inside of ER in plant cells as they encounter various environmental stimuli. We welcome all types of research articles focused on (but not limited to): different stages of endoplasmic reticulum quality control for protein folding processes such as unfolded protein response (UPR), endoplasmic-reticulum-associated degradation (ERAD) or ER stress-induced autophagy of a model or non-model plant in response to fluctuated external conditions such as ion concentration, temperature, water and nutrient availability or light intensity.

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.
