“…However, the later increase (24 h after salt induction) of H3K4me3 on the locus H3K4me3 might be, in this case, to label the active state of OsMYB91. The precocious decrease of H3K27me3 suggested that the removal of H3K27me3 might play an important role in the induction process, supporting previous results showing that active demethyaltion of H3K27me3 is required for inducible gene activation[48]. These observations showed that dynamic chromatin modification might be an early step for salt stress-induced expression of OsMYB91.The salt-stress responsiveness of OsMYB91, the enhanced salt-stress tolerance and the restrained growth of the over-expression plants, and reduced stress tolerance of the RNAi plants suggested that OsMYB91 was a transcription regulator that might activate gene expression program to coordinate salt-stress tolerance and growth retrains.…”

“…In plants, H3K27me3 marked genes have very low expression levels and a high degree of tissue specificity, consistent with the function of H3K27me3 in maintaining gene repression during growth (Lafos et al, ; Turck et al, ; Wang et al, ; Zhang et al, ). Despite the fact that many genes dynamically regulated in response to environmental cues are marked by H3K27me3 (Charron, He, Elling, & Deng, ; Li et al, ), H3K27me3 itself does not interfere with or inhibits their transcriptional activation (Kwon, Lee, Choi, & Chung, ; Liu, Ding, Fromm, & Avramova, ; Liu, Fromm, & Avramova, ).…”

During their lifespan, plants respond to a multitude of stressful factors. Dynamic changes in chromatin and concomitant transcriptional variations control stress response and adaptation, with epigenetic memory mechanisms integrating environmental conditions and appropriate developmental programs over the time. Here we analyzed transcriptome and genome‐wide histone modifications of maize plants subjected to a mild and prolonged drought stress just before the flowering transition. Stress was followed by a complete recovery period to evaluate drought memory mechanisms. Three categories of stress‐memory genes were identified: i) “transcriptional memory” genes, with stable transcriptional changes persisting after the recovery; ii) “epigenetic memory candidate” genes in which stress‐induced chromatin changes persist longer than the stimulus, in absence of transcriptional changes; iii) “delayed memory” genes, not immediately affected by the stress, but perceiving and storing stress signal for a delayed response. This last memory mechanism is described for the first time in drought response. In addition, applied drought stress altered floral patterning, possibly by affecting expression and chromatin of flowering regulatory genes. Altogether, we provided a genome‐wide map of the coordination between genes and chromatin marks utilized by plants to adapt to a stressful environment, describing how this serves as a backbone for setting stress memory.

“…In Medicago truncatula, MtJMJC5 (Medtr4g066020), an ortholog of AtJMJ30/JMJD5 , may play a role in epigenetic regulation of the link between the circadian clock and cold signaling (Shen et al, 2016). In rice, OsJMJ705 is a biotic stress-responsive H3K27me2/3 demethylase that may remove H3K27me3 from marked defense-related genes and increase their basal and induced expression during pathogen infection (Li et al, 2013). OsJMJ706 , encodes a heterochromatin-associated H3K9 demethylase, is reported to involve in the regulation of flower development in rice (Sun and Zhou, 2008).…”

Histone modifications, such as methylation and demethylation, play an important role in regulating chromatin structure and gene expression. The JmjC domain-containing proteins, an important family of histone lysine demethylases (KDMs), play a key role in maintaining homeostasis of histone methylation in vivo. In this study, we performed a comprehensive analysis of the jumonji C (JmjC) gene family in the soybean genome and identified 48 JmjC genes (GmJMJs) distributed unevenly across 18 chromosomes. Phylogenetic analysis showed that these JmjC domain-containing genes can be divided into eight groups. GmJMJs within the same phylogenetic group share similar exon/intron organization and domain composition. In addition, 16 duplicated gene pairs were formed by a Glycine-specific whole-genome duplication (WGD) event approximately 13 million years ago (Mya). By investigating the expression profiles of these gene pairs in various tissues, we showed that the expression pattern is conserved in the polyploidy-derived JmjC duplicates, demonstrating that the majority of GmJMJs were preferentially retained after the most recent WGD event and suggesting important roles for demethylase duplications in soybean evolution. These results shed light on the evolutionary history of this family in soybean and provide insights into the JmjCs which will be helpful to reveal their functions in controlling soybean development.
