Special Issue Information
Dear Colleagues,
Mitochondria and chloroplast are cellular organelles that have been regarded to have originated by endosymbiosis. Due to their long-lasting symbiotic relationship, these organelles are profoundly involved in the genetic and biochemical function of cells. In plants, mitochondria and chloroplast are not only dedicated to their well-known roles, which are respiration and photosynthesis, respectively, but also take part in other important processes in plant development and responses to environmental stimuli. These functions rely on interactions between nuclear and organellar genomes as well as direct actions of genes coded by organellar genomes. Therefore, understanding of organellar genomes and their interaction with nuclear genome is one of the fundamental issues in plant biology.
In comparison to the relationship between phenotypes and nuclear genomes, the phenotypes caused by organellar genomes or their interaction with the nuclear genome have not been analyzed in depth in plants. Extremely limited segregation of polymorphic sequences by crosses and lack of efficient mutagenesis or transformation technologies have been obstacles of functional genomics study in organelles. In addition, the complicated structure of the plant mitochondrial genome has long hampered reliable sequencing analysis and estimation of the genome composition in vivo. However, recent improvements in sequencing technologies, targeted mutagenesis methodologies, and phenotype analysis systems are providing new opportunities to get answers to problems that have not been solved for a long time in the field of organellar functional genomics.
In this Special Issue, we focus on the role of organellar genomes in plant development and responses to environmental stimuli. We also welcome research on methodologies to enhance the efficiency of functional genomics studies for plant organelles, and on the analysis of interactions between nuclear and organellar genomes.

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.
