“…Arabidopsis and rice genomes encode 49 and 34 SET domain-containing proteins, respectively1123. In Vitis vinifera , 33 genes belonging to this family of chromatin remodelling factors were identified by Aquea et al 25. This number is also similar to that found in other organisms including zebrafish, human, and fruit fly which have 58, 47 and 29 SET domain-containing proteins, respectively26.…”

SET domain-containing genes catalyse histone lysine methylation, which alters chromatin structure and regulates the transcription of genes that are involved in various developmental and physiological processes. The present study identified 53 SET domain-containing genes in C4 panicoid model, foxtail millet (Setaria italica) and the genes were physically mapped onto nine chromosomes. Phylogenetic and structural analyses classified SiSET proteins into five classes (I–V). RNA-seq derived expression profiling showed that SiSET genes were differentially expressed in four tissues namely, leaf, root, stem and spica. Expression analyses using qRT-PCR was performed for 21 SiSET genes under different abiotic stress and hormonal treatments, which showed differential expression of these genes during late phase of stress and hormonal treatments. Significant upregulation of SiSET gene was observed during cold stress, which has been confirmed by over-expressing a candidate gene, SiSET14 in yeast. Interestingly, hypermethylation was observed in gene body of highly differentially expressed genes, whereas methylation event was completely absent in their transcription start sites. This suggested the occurrence of demethylation events during various abiotic stresses, which enhance the gene expression. Altogether, the present study would serve as a base for further functional characterization of SiSET genes towards understanding their molecular roles in conferring stress tolerance.

“…The expression profile of enzymes responsible for PTMs has been determined in many fruit species, suggesting their potential role in specific moments of growth, in both early and late fruit development (described below; Janssen et al, 2008; Aquea et al, 2010; Cigliano et al, 2013). Functional analyses that have contributed to attribute a function to histone modifiers in fruits were performed mainly in tomato model: for example the PRC2 Polycomb repressive complex is composed by different subunits with specific functions among which the deposition of H3K27me3 mark, with a fundamental role in fruits shape, flower formation, cutin accumulation, and fruit shelf life in tomato (How-Kit et al, 2010; Liu D. D. et al, 2012; Boureau et al, 2016; Liu et al, 2016).…”

Rosaceae is a family with an extraordinary spectrum of fruit types, including fleshy peach, apple, and strawberry that provide unique contributions to a healthy diet for consumers, and represent an excellent model for studying fruit patterning and development. In recent years, many efforts have been made to unravel regulatory mechanism underlying the hormonal, transcriptomic, proteomic and metabolomic changes occurring during Rosaceae fruit development. More recently, several studies on fleshy (tomato) and dry (Arabidopsis) fruit model have contributed to a better understanding of epigenetic mechanisms underlying important heritable crop traits, such as ripening and stress response. In this context and summing up the results obtained so far, this review aims to collect the available information on epigenetic mechanisms that may provide an additional level in gene transcription regulation, thus influencing and driving the entire Rosaceae fruit developmental process. The whole body of information suggests that Rosaceae fruit could become also a model for studying the epigenetic basis of economically important phenotypes, allowing for their more efficient exploitation in plant breeding.

“…Probably, the photosynthetically active cells, i.e., leaf cells, contain many chloroplasts, which to function properly require a high level of sirtuins encoded by VvSRT2 genes, which in turn stabilize the chromatin structure and/or regulate the transcription of other chloroplast genes. These scientists supported their hypothesis by the research of Aquea et al (2010), who observed VvSRT2 expression in the leaves, flowers and fruits. It was not detected only in the roots, which might indicate that a high level of the VvSRT2 gene expression was correlated with the activity of the photosynthetic cells.…”

Sirtuins are proteins belonging to the group of NADH-dependent deacetylase and mono-ADP-ribosyltransferase enzymes. Sirtuins have been discovered for the first time in yeasts, subsequent studies have shown their presence in bacteria, plants and animals. These enzymes are frequently called longevity enzymes due to the fact that they are part of genetic apparatus involved in aging control. In animals, sirtuins are key regulators of cell defense in response to stress caused by many metabolic processes; they are also involved in the regulation of cell division, metabolism, gene silencing and genetic material repair as well as apoptosis. Thus far, only several well-known research teams have been studying plant proteins resembling animal sirtuins. Considering the fact how essential functions sirtuins play in other organisms, it is extremely interesting to understand their role in plants, especially that the knowledge about them is still limited. It is believed that the function of sirtuins in Arabidopsis thaliana is associated with mitochondrial energy metabolism. Possibly they may also control the synthesis of auxins or proteins involved in their transport, or they may be responsible for regulating cellular response to auxin action. In rice, sirtuins are necessary for the protection against genomic instability and cell damage that guarantee their growth. They also take part in a defensive response against Pseudomonas syringae. They may also be involved in the ripening of fruits.Moreover, their functions are associated with photosynthetic activity and aging of leaves.
