Epigenetic control of plant senescence and linked processes

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.

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.

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.

Genome-wide analysis of histone modifications by ChIP-on-chip

TL;DR: ChIP-on-chip methods for analyzing histone modification patterns at genome-scale in mammalian cells have been proposed in this paper, which combines the specificity of chromatin immunoprecipitation with the unbiased, high-throughput capabilities of microarrays.

Don't kill the messenger: Long-distance trafficking of mRNA molecules

TL;DR: The identity and potential function of phloem-sap mRNA molecules, the factors facilitating RNA transport, and the rationale for their action as long-distance signaling agents in the control of developmental processes are discussed.

EDS1 contributes to nonhost resistance of Arabidopsis thaliana against Erwinia amylovora.

TL;DR: It is shown that EDS1 is a positive regulator of nonhost resistance against E. amylovora in A. thaliana and hypothesize that it controls the production of several effective defenses against the bacterium through the action of WRKY46 and WRKY54, while WRKY70 acts as a negative regulator.

Abiotic Stress and Induced DNA Hypomethylation Cause Interphase Chromatin Structural Changes in Rice rDNA Loci

TL;DR: A role for chromatin plasticity in a world of climate changes is suggested after 5-Azacytidine (5-AC), a DNA hypomethylating drug, greatly increased 45S rDNA chromatin decondensation and interestingly was able to induce polarization of centromeres in rice interphase nuclei.
