Special Issue Information

Dear Colleagues,

Plant genomics is a branch of biology which aims to explore all the aspects of an entire genome, from genetic composition to structure, from organization to functions, and genetic connections. Currently, the advance of ‘omics’ technologies and bioinformatics tools have largely contributed to dissecting the genetic architecture of plant genomes and also to identifying key genes and their combinatorial interaction in plant growth and development. The recent new approaches on genome editing have further enriched this expanding field. Moreover, in recent years, an enhanced focus has been paid to understanding epigenetics and genome-wide distribution of epigenetic changes, which appears essential for dissecting all aspects of genetic studies.

Epigenetics refers to all molecular pathways which determine changes in genome structure and activity without alteration in the DNA sequence, resulting in stable heritable and nonheritable phenotypes. Overall, these pathways act through chromatin remodeling processes tracing the chromatin/epigenetic landscape of the genome (epigenome). Moreover, they interplay with each other rather than working separately and contribute to the control of several nuclear processes, such as DNA transcription, replication, recombination, and repair.

Typically, epigenetic machinery includes variants and post-translational modifications of histones, covalent modifications of DNA bases, like cytosine methylation, and biogenesis of noncoding RNAs, including long and short noncoding RNAs. However, the epigenomics field is ever-broadening, and new epigenetic/epitranscriptomic changes have been identified in all the kingdoms of living organisms, involving a network of chromatin-modifying enzymes, chromatin remodeling complexes, signaling kinases, and also cellular metabolism.

The currently available literature has evidenced that naturally occurring epigenetic processes are essential for defining cell identities and regulating several functions of living organisms which can be adversely affected when they occur incorrectly. This is particularly documented in animal systems by advanced research carried out in the field of human health. Consistently, in plant the epigenetic processes, in addition to playing a role in heritable genetic diversity and evolution, are essential for growth and development. Moreover, epigenetic changes can also arise under the influence of the environment and be connected to or driven by biotic and abiotic agents, thus contributing to plant growth plasticity and stress response. However, despite all this information, many aspects of the molecular and cellular mechanisms which operate in and are modulated by epigenetic processes in plants need to be clarified.

This Special issue will collect meaningful original research, reviews, and perspectives related to all these aspects of plant epigenetics. Contributions dealing with the potential of epigenetic variations for planning new crop-improvement strategies and plant biotechnologies will also be welcome.

Epigenetic Regulation of Auxin-Induced Somatic Embryogenesis in Plants

Somatic embryogenesis (SE) that is induced in plant explants in response to auxin treatment is closely associated with an extensive genetic reprogramming of the cell transcriptome. The significant modulation of the gene transcription profiles during SE induction results from the epigenetic factors that fine-tune the gene expression towards embryogenic development. Among these factors, microRNA molecules (miRNAs) contribute to the post-transcriptional regulation of gene expression. In the past few years, several miRNAs that regulate the SE-involved transcription factors (TFs) have been identified, and most of them were involved in the auxin-related processes, including auxin metabolism and signaling. In addition to miRNAs, chemical modifications of DNA and chromatin, in particular the methylation of DNA and histones and histone acetylation, have been shown to shape the SE transcriptomes. In response to auxin, these epigenetic modifications regulate the chromatin structure, and hence essentially contribute to the control of gene expression during SE induction. In this paper, we describe the current state of knowledge with regard to the SE epigenome. The complex interactions within and between the epigenetic factors, the key SE TFs that have been revealed, and the relationships between the SE epigenome and auxin-related processes such as auxin perception, metabolism, and signaling are highlighted.
