Recent progress on the regulation and alteration of histone modification in response to the abiotic stresses, drought, high-salinity, heat, and cold in plants is summarized.
Abstract
Chromatin regulation is essential to regulate genes and genome activities. In plants, the alteration of histone modification and DNA methylation are coordinated with changes in the expression of stress-responsive genes to adapt to environmental changes. Several chromatin regulators have been shown to be involved in the regulation of stress-responsive gene networks under abiotic stress conditions. Specific histone modification sites and the histone modifiers that regulate key stress-responsive genes have been identified by genetic and biochemical approaches, revealing the importance of chromatin regulation in plant stress responses. Recent studies have also suggested that histone modification plays an important role in plant stress memory. In this review, we summarize recent progress on the regulation and alteration of histone modification (acetylation, methylation, phosphorylation, and SUMOylation) in response to the abiotic stresses, drought, high-salinity, heat, and cold in plants.

A hit-and-run heat shock factor governs sustained histone methylation and transcriptional stress memory.

TL;DR: It is shown that transcriptional memory after HS is associated with sustained H3K4 hyper‐methylation and depends on a hit‐and‐run transcription factor, thus providing a molecular framework for HS memory.

Multiplex Genome Engineering Using CRISPR/Cas Systems

TL;DR: The type II prokaryotic CRISPR (clustered regularly interspaced short palindromic repeats)/Cas adaptive immune system has been shown to facilitate RNA-guided site-specific DNA cleavage as discussed by the authors.

Multiplex Genome Engineering Using CRISPR/Cas Systems

TL;DR: Two different type II CRISPR/Cas systems are engineered and it is demonstrated that Cas9 nucleases can be directed by short RNAs to induce precise cleavage at endogenous genomic loci in human and mouse cells, demonstrating easy programmability and wide applicability of the RNA-guided nuclease technology.

Role of Histone H3 Lysine 27 Methylation in Polycomb-Group Silencing

TL;DR: The purification and characterization of an EED-EZH2 complex, the human counterpart of the Drosophila ESC-E(Z) complex, is reported, and it is demonstrated that the complex specifically methylates nucleosomal histone H3 at lysine 27 (H3-K27).
