“…In maize roots, salt stress induces changes in histone acetylation in the promoter region of cell cycle genes (Zhou et al ., ,b). Elevated acetylation levels in H3K9 and H3K27 sites lead to transcriptional activation of a peroxidase (POX)‐encoding genes in Beta vulgaris and Beta maritima under salt‐stress conditions (Yolcu et al ., ).…”

Salt imposes osmotic, ionic, and secondary stresses on plants. Over the past two decades, many determinants of salt tolerance and their regulatory mechanisms have been identified and characterized using molecular genetics and genomics approaches. This review describes recent progress in deciphering the mechanisms controlling ion homeostasis, cell activity responses, and epigenetic regulation in plants under salt stress. Finally, we highlight research areas that require further research to reveal new determinants of salt tolerance in plants.

“…The fine‐tuning of acetylation by HATs and HDACs is important for plants to adapt to changing environmental conditions. High‐salinity treatments often induce the deposition of active histone marks such as H3K9K14Ac and H3K4me3 and decrease the deposition of repressive marks such as H3K9me2 and H3K27me3 on salt stress‐responsive genes (Sokol et al 2007; Chen et al 2010; Yolcu et al 2016). Luo et al reported that the expression of HD2C was repressed by ABA and NaCI, and hd2c mutant was more sensitive to ABA and NaCI (Luo et al 2012).…”

In eukaryotic cells, gene expression is greatly influenced by the dynamic chromatin environment. Epigenetic mechanisms, including covalent modifications to DNA and histone tails and the accessibility of chromatin, create various chromatin states for stress-responsive gene expression that is important for adaptation to harsh environmental conditions. Recent studies have revealed that many epigenetic factors participate in abiotic stress responses, and various chromatin modifications are changed when plants are exposed to stressful environments. In this review, we summarize recent progress on the cross-talk between abiotic stress response pathways and epigenetic regulatory pathways in plants. Our review focuses on epigenetic regulation of plant responses to extreme temperatures, drought, salinity, the stress hormone abscisic acid, nutrient limitations and ultraviolet stress, and on epigenetic mechanisms of stress memory.

“…Variations in the outside environment could put the plant metabolism out of homeostasis (Foyer & Noctor, 2005), and create necessity for the plant to harbor some advanced genetic and metabolic mechanisms within its cellular system (Apel & Hirt, 2004;Gill & Tuteja, 2010). Plants possess an array of protective mechanisms acquired during the course of evolution to combat adverse environmental situations (Yolcu et al, 2016).…”

Mangaba tree (Hancornia speciosa Gomes) is a tropical fruit species from Brazil and presents socioeconomic potential. The objective of this study was to determine antioxidant activity, rutin content and genetic similarity among in vivo and in vitro matrices and progenies of six accessions from the Mangaba Active Germplasm Bank of the Embrapa Coastal Tablelands, SE, Brazil. Young leaves of adult matrix plants and in vitro callus methanolic extracts obtained from young leaves resulted in differences between the accessions for the rutin content and high antioxidant activity. The Costa Azul accession, from Bahia, Brazil outstood with values above 3,000 g of dry extract/g of DPPH (2.2-diphenyl-1-picrilhydrazyl) in in vitro callus coming from nodal and internodal segments (3,023.73 and 3,136.80 g of dry extract/g of DPPH, respectively). Rutin was not found in extracts resulting from in vitro callus of mangaba tree. The difference among the values obtained for DPPH analysis are superior when compared with in vivo leaf extract, with the in vitro Costa Azul accession (nodal and internodal) outstanding, concluding that in vitro callus induction can interfere with chemical compounds of the plant. The markers detect genetic similarity under in vitro cultivation conditions. The Costa Azul accession group itself in isolation from others and EC 50 concentrations differentiated between leaf and callus are obtained. O EC 50 is superior in extracts deriving from in vitro callus, with the in vitro Costa Azul accession (nodal and internodal).
