“…In addition to several studies that have documented the critical role of SDG genes in plant developmental processes, histone methylation and SDG genes have also been shown to play a role in stress responses [ 6 , 7 , 17 – 20 ]. Previous studies have revealed that the histone methyltransferases MEA and SWN play an important role in Arabidopsis seed development, dormancy, and germination [ 21 , 22 ].…”

Background Histone lysine methylation plays an important role in plant development and stress responses by activating or repressing gene expression. Histone lysine methylation is catalyzed by a class of SET-domain group proteins (SDGs). Although an increasing number of studies have shown that SDGs play important regulatory roles in development and stress responses, the functions of SDGs in apple remain unclear. Results A total of 67 SDG members were identified in the Malus×domestica genome. Syntenic analysis revealed that most of the MdSDG duplicated gene pairs were associated with a recent genome-wide duplication event of the apple genome. These 67 MdSDG members were grouped into six classes based on sequence similarity and the findings of previous studies. The domain organization of each MdSDG class was characterized by specific patterns, which was consistent with the classification results. The tissue-specific expression patterns of MdSDGs among the 72 apple tissues in the different apple developmental stages were characterized to provide insight into their potential functions in development. The expression profiles of MdSDGs were also investigated in fruit development, the breaking of bud dormancy, and responses to abiotic and biotic stress; the results indicated that MdSDGs might play a regulatory role in development and stress responses. The subcellular localization and putative interaction network of MdSDG proteins were also analyzed. Conclusions This work presents a fundamental comprehensive analysis of SDG histone methyltransferases in apple and provides a basis for future studies of MdSDGs involved in apple development and stress responses.

“…This defense system has the ability to manage the plant genes in the regulation of all plant processes of growth and development. This regulation is considered stress management (Barozai and Aziz, 2018). The heatstress management could be achieved viaplant conventional breeding and plant engineering using the genetic approaches (Ye et al, 2019), as well as many agronomic practices (Fahad et al, 2017).…”

T HE production of protected cultivation of vegetables could be considered as a sustainable solution in arid and semi-arid regions.These regions already suffer from raising temperature andthe global warmingwill aggravate this, whichrepresents a great challenge facing our universe nowadays. Hence, the production of vegetables and tomato under greenhouse system during the high temperatures may be considered a serious problem should be avoided in these arid zonesin summer due to heat stress.The heat stress may cause a lot of troubles for the tomato seedlings in greenhouses in summer starting with the photosynthetic rate, and the metabolism processes in seedlings and in turn the growth and development of these seedlings. Although studies have recognized heat stress on tomato seedlings, research has yet to systematically investigate the effect of heat stress on tomato seedlings in greenhouse in summer under arid and semi-arid regions particularly in developing countries, which their greenhouses have not any climate controllers. Therefore, the management of tomato seedlings may need to address the production problems caused by heat stress in greenhouse conditions particularly in arid and semi-arid zones

“…Recently, Secco et al (2017) reviewed in detail some of the advancement on involvement of histone modifications, histone variants and DNA methylation in response to nutrient stresses. Epigenetics , regulatory tools of gene expression are also vital for plants survival especially when they are exposed to biotic stresses such as bacteria, viruses, fungi, parasites, insects and weeds (Barozai and Aziz, 2018). Dubey and Jeon (2017) explained in detail the host epigenetic modifications during Magnaporthe oryzae pathogenesis progress and host-pathogen interactions, while suggesting the role of epigenetics in the epidemiology for future research and studies.…”

Traditional Chinese medicine is commonly used in China and so many other Asian and western Countries. Epigenetics relates to heritable alternations in chromatin architecture that do not involve changes in the underlying DNA sequence but profoundly affect gene expression and impact cellular function. Epigenetic regulation is attained by specific mechanisms involving DNA methylation, histone posttranslational modifications and the action of noncoding RNAs. Epigenetic variations also involved in the control of plant developmental processes and contribute in shaping phenotypic plasticity to the environment. Epigenetics has considerable impact on evolution and epigenetic epidemiology which has shown the intricate function between the environment and epigenetics. DNA methylation is an epigenetic mechanism that regulates gene expression and may affect plant growth, development and acclimation. DNA methylation is associated with gene expression and morphological variation. Plants, utilization of the epigenetic approach are used to manage and resist the fungal, bacterial and others biotic stresses; microbes, also employ epigenetic mechanisms to modify growth and pathogenicity, leading to resistance against plant-host immune system. DNA methylation is a chemical modification process where the methyltransderass (DNMTs) are catalyzed by selective addition of methyl groups to form 5-methylcytosine in CpG sequences. A mixture of herbs and fruits used in traditional Chinese medicine maybe use to decline diseases by adding and removing epigenetic marks on DNA. Epigenetics has been introduced to the area of TCM recently, which resulting in the hypothesis of an epigenetic role in the modern pharmacology of TCM prescriptions. Epigenetics is the partial material basis of TCM syndrome diversity, and the microscopic index of epigenetics can be an important supplement to the macroscopic syndrome differentiation of TCM syndromes. The role of epigenetic information is in developmental gene regulation, natural variation of gene expression levels, and response to the environment. The significant attention has started about the potential for epigenetic information to contribute to heritable variation in many species, even traditional Chinese herbs.
