Dear Colleagues,

This Special Issue is the continuation of our previous special issue "Plant Mitochondria".

The primary function of mitochondria is respiration, where catabolism of the substrates is coupled to ATP synthesis via oxidative phosphorylation. In plants, mitochondrial composition is relatively complex and flexible and has specific pathways to support photosynthetic processes in illuminated leaves. Plant mitochondria also play important roles in a variety of cellular processes associated with carbon, nitrogen, phosphorus and sulphur metabolism. Research on plant mitochondria has rapidly developed in the last few decades with the availability of the genome sequences for a wide range of model and crop plants. Recent prominent themes in plant mitochondrial research include linking mitochondrial composition to environmental stress responses, and how this oxidative stress impacts on the plant mitochondrial function. Similarly, interest in the signalling capacity of mitochondria, the role of reactive oxygen species, and retrograde and anterograde signalling has revealed the transcriptional changes to stress-responsive genes as a framework to define specific signals emanating to and from the mitochondrion. There has also been considerable interest in the unique RNA metabolic processes in plant mitochondria including RNA transcription, RNA editing, the splicing of group I and group II introns and RNA degradation and translation.

Following on from the success of the first Special Issue focused on “Plant Mitochondria” in the International Journal of Molecular Sciences, we are happy to announce a second Special Issue “Plant Mitochondria 2.0”. This first Special Issue attracted a total of 19 accepted articles, with 15 original research articles and 4 review articles broadly covering the field of plant mitochondrial research. The first issue followed the International Conference of Plant Mitochondrial Biology in Hangzhou, China, in 2017, which brought together the plant mitochondria research community. “Plant Mitochondria 2.0” will follow this year’s meeting in Ein Gedi, Israel (www.icpmb2019.com) and will cover a selection of recent research topics and timely review articles in the field of plant mitochondria research. Experimental papers, up-to-date review articles, and commentaries are all welcome.

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.
