Abstract Maintaining proper DNA methylation levels in the genome requires active demethylation of DNA. However, removing methyl group from a modified cytosine is chemically difficult and therefore, underlying mechanism had remained unclear for many years. The discovery first eukaryotic demethylase, Arabidopsis thaliana REPRESSOR OF SILENCING 1 (ROS1), led to elucidation 5‐methylcytosine base excision repair demethylation. In 20 years since ROS1 was discovered, our understanding this pathway, as well its regulation biological functions plants, has greatly expanded. These exciting developments have laid groundwork further dissecting regulatory mechanisms demethylation, with potential applications epigenome editing facilitate crop breeding gene therapy.

Nucleosome is the basic subunit of chromatin, consisting approximately 147bp DNA wrapped around a histone octamer, containing two copies H2A, H2B, H3 and H4. A linker H1 can bind nucleosomes through its conserved GH1 domain, which may promote chromatin folding into higher-order structures. Therefore, complexity histones act importantly for specifying gene activities. Histone variants, encoded by separate genes characterized only few amino acids differences, affect nucleosome packaging stability, then modify properties. Serving as carriers pivotal genetic epigenetic information, variants have profound significance in regulating plant growth development, response to both biotic abiotic stresses. At present, biological functions become research hotspot. Here, we summarize recent researches on functions, molecular chaperons regulatory mechanisms plant, propose some novel directions further study field.

Systematic genome-wide analysis of Sorghum bicolor revealed the identification a total 48 homologous genes comprising 21 proline-rich proteins (PRPs) and 27 hybrid (HyPRPs). Comprehensive scrutiny these gene homologs was conducted for structure, phylogenetic investigations, chromosome mapping, subcellular localization proteins. Promoter uncovered regions rich with phosphorous- (BIHD), ammonium-, sulfur-responsive (SURE), iron starvation-responsive (IRO2) along biotic, abiotic, development-specific cis-elements. Further, PRPs exhibit more methylation acetylation sites in comparison HyPRPs. miRNAs have been predicted which might play role cleavage translation inhibition. Several SbPRP were stimulated tissue-specific manner under drought, salt, heat, cold stresses. Additionally, exposure plants to abscisic acid (ABA) zinc (Zn) also triggered PRP tissue-dependent way. Among them, SbPRP17 has found upregulated markedly all tissues irrespective stress imposed. The expressions SbHyPRPs, especially SbHyPRP2, SbHyPRP6, SbHyPRP17 activated stresses three tissues. On other hand, SbHyPRP8 (root only) SbHyPRP12 (all tissues) highly responsive ABA while SbHyPRP26 induced by drought Zn stem. Taken together, this study indicates critical roles that SbPRPs SbHyPRPs during diverse abiotic conditions notably plausible upon zinc, crucial micronutrient plants.
