TLDR
The review outlines the concept of epigenetic control of interconnected regulatory pathways steering stress responses and plant development and summarizes recent findings on global alterations in chromatin structure, histone and DNA modifications, and ATP-dependent chromatin remodelling during plant senescence and linked processes.Abstract:
Senescence processes are part of the plant developmental programme. They involve reprogramming of gene expression and are under the control of a complex regulatory network closely linked to other developmental and stressresponsive pathways. Recent evidence indicates that leaf senescence is regulated via epigenetic mechanisms. In the present review, the epigenetic control of plant senescence is discussed in the broader context of environmentsensitive plant development. The review outlines the concept of epigenetic control of interconnected regulatory pathways steering stress responses and plant development. Besides giving an overview of techniques used in the field, it summarizes recent findings on global alterations in chromatin structure, histone and DNA modifications, and ATPdependent chromatin remodelling during plant senescence and linked processes.read more

Somatic embryogenesis - Stress-induced remodeling of plant cell fate.
TL;DR: The present knowledge on chromatin-based mechanisms potentially involved in the somatic-to-embryogenic developmental transition is summarized, emphasizing the potential role of the chromatin to integrate stress, hormonal, and developmental pathways leading to the activation of the embryogenic program.

Blocking histone deacetylation in Arabidopsis induces pleiotropic effects on plant gene regulation and development. [Erratum: June 19, 2001, v. 98 (13), p. 7647.]
TL;DR: In this article, AtHD1 expression and deacetylation profiles were associated with various developmental abnormalities, including early senescence, ectopic expression of silenced genes, suppression of apical dominance, homeotic changes, heterochronic shift toward juvenility, flower defects, and male and female sterility.

Stress-induced structural changes in plant chromatin
TL;DR: This review highlights some of the most recent findings on nuclear reorganization, histone variants, hist one chaperones, DNA- and histone modifications, and somatic and meiotic heritability in connection with stress.

Integration of multi-omics techniques and physiological phenotyping within a holistic phenomics approach to study senescence in model and crop plants.
TL;DR: This review addresses the need for the integration of multi-omics techniques and physiological phenotyping into holistic phenomics approaches to dissect the complex phenomenon of senescence and to elucidate the underlying molecular processes.
Journal ArticleDOI
Plant organ senescence - regulation by manifold pathways.
TL;DR: A universal nature of senescence is demonstrated, despite this process occurring in organs that have completely different functions, it is very similar; this will provide a powerful tool for plant physiology research.

Plant transposable elements: where genetics meets genomics
TL;DR: The recent availability of large quantities of genomic sequence has led to a shift from the genetic characterization of single elements to genome-wide analysis of enormous transposable-element populations, particularly in plants.

Vernalization requires epigenetic silencing of FLC by histone methylation
Ruth Bastow,Joshua S. Mylne,Clare Lister,Zachary B. Lippman,Robert A. Martienssen,Caroline Dean +5 more
TL;DR: It is shown that vernalization causes changes in histone methylation in discrete domains within the FLC locus, increasing dimethylation of lysines 9 and 27 on histone H3, which identify silenced chromatin states in Drosophila and human cells.

Gardening The Genome: DNA Methylation in Arabidopsis thaliana
TL;DR: Experiments in Arabidopsis thaliana have begun to address crucial questions about how DNA methylation is established and maintained, and one cardinal insight has been the discovery thatDNA methylation can be guided by small RNAs produced through RNA-interference pathways.

TL;DR: An unexpected role for DNA methylation is reported in regulation of the Arabidopsis thaliana immune system and changes within repetitive sequences or transposons can regulate neighboring genes in response to SA stress.
