Structural Rearrangements, Intracellular DNA Transfer and Functional Aspects of Plant and Green Algae Genomes in Multi-Omics Era

Dear Colleagues,

Earth is a plant-oriented planet, and plants have particular importance. Plants add value to Earth's diversity and are fundamental to all life. Molecular diversity in plant groups enables study by researchers. Plant organelles such as chloroplast, mitochondria, and the nucleus have enigmatic cellular compartments where complex biochemical and molecular processes are essential for the plant. According to the endosymbiotic theory, chloroplast and mitochondria organelles were obtained from their ancestral bacteria billions of years ago. With the development of next-generation sequencing approaches, thousands of organellar genomes have been characterized. This analysis provides an understanding of the plant genome complexity, structural variations, and evolutionary forces that adapt to environmental factors. In addition, the characterization of green algae helps us to understand the evolutionary patterns of both vascular and non-vascular plants. Therefore, studying organellar genomes offers an excellent opportunity to understand the molecular mechanism of plant organelles. Moreover, how do structural changes in the organellar genomes conflate with the nuclear genome? Modern high-throughput sequencing technologies as well as multi-omics approaches could be useful tools to seek the answer.

This Special Issue focuses on the perspective of plant nucleus, chloroplast, and mitochondrial genome complexity, including extensive genome rearrangement, intracellular gene transfer, mutation, and evolution, and not limited to the algal genomes. This issue also covers understanding functional aspects such as the diversity of essential compounds synthesized in the plant organelles that are of biological, medical, and industrial importance by multi-omics approaches. This research topic includes an excellent combination of reviews and original research articles focused on comparative and evolutionary studies, variations within and among populations, functional aspects studies, phylogenomic and other related topics of the nuclear and organellar genomes of plants and green algae, and all are welcomed. The general characteristics of the genome or the lack of novelty in genomic or phylogenomic studies will not be considered for this Special Issue.

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.
