“…Besides, PcG proteins are act as histone modifying enzymes and reported to regulate the embryo and endosperm proliferation and anterio-posterior organization during seed development 80 . The possible role of epigenetic mechanism of these polycomb proteins in plant reproductive development particularly from flower to seed development is well reported earlier 81 . Another unpublished work at ICAR-NRCB, reported failure of certain female fertile accessions to set seeds under a set of environmental condition but the reason behind this behavior remains undiscovered.…”

Banana, one of the most important staple fruit among global consumers is highly sterile owing to natural parthenocarpy. Identification of genetic factors responsible for parthenocarpy would facilitate the conventional breeders to improve the seeded accessions. We have constructed Protein–protein interaction (PPI) network through mining differentially expressed genes and the genes used for transgenic studies with respect to parthenocarpy. Based on the topological and pathway enrichment analysis of proteins in PPI network, 12 candidate genes were shortlisted. By further validating these candidate genes in seeded and seedless accession of Musa spp. we put forward MaAGL8, MaMADS16, MaGH3.8, MaMADS29, MaRGA1, MaEXPA1, MaGID1C, MaHK2 and MaBAM1 as possible target genes in the study of natural parthenocarpy. In contrary, expression profile of MaACLB-2 and MaZEP is anticipated to highlight the difference in artificially induced and natural parthenocarpy. By exploring the PPI of validated genes from the network, we postulated a putative pathway that bring insights into the significance of cytokinin mediated CLAVATA(CLV)–WUSHEL(WUS) signaling pathway in addition to gibberellin mediated auxin signaling in parthenocarpy. Our analysis is the first attempt to identify candidate genes and to hypothesize a putative mechanism that bridges the gaps in understanding natural parthenocarpy through PPI network.

“…Dynamic changes of DNA methylation in response to low temperature represent a potentially mechanism able to regulate gene expression in both annual and perennial plants. DNA methylation changes induced by vernalization promoting flowering have been extensively studied in some overwintering annual plants [19] , [20] , [21] . However, the role of DNA methylation in overwintering perennial plants with different lifestyles is still obscure because of the absence of study, so alternative regulatory mechanisms are expected to occur in perennial plants.…”

“…Especially, we found that DNA methylation levels in the rhizomes of American ginseng during dormant season presented an increasing, unchanging, decreasing patterns. This indicated that cooling in autumn could cause DNA hypermethylation, whereas warming in spring could cause DNA hypomethylation; these might be totally different with that in many annual plant species as many results showed that cold temperature resulted in hypomethylation extensively in many annual plant species [3] , [4] , [5] , [19] , [20] , [21] . We also noticed the DNA methylation dynamics during major developmental transitions of American ginseng that is a decreasing from rhizome to seedling but an increasing from juvenile to adult.…”

Background Ginsenosides accumulation responses to temperature are critical to quality formation in cold-dependent American ginseng. However, the studies on cold requirement mechanism relevant to ginsenosides have been limited in this species. Methods Two experiments were carried out: one was a multivariate linear regression analysis between the ginsenosides accumulation and the environmental conditions of American ginseng from different sites of China and the other was a synchronous determination of ginsenosides accumulation, overall DNA methylation, and relative gene expression in different tissues during different developmental stages of American ginseng after experiencing different cold exposure duration treatments. Results Results showed that the variation of the contents as well as the yields of total and individual ginsenosides Rg1, Re, and Rb1 in the roots were closely associated with environmental temperature conditions which implied that the cold environment plays a decisive role in the ginsenoside accumulation of American ginseng. Further results showed that there is a cyclically reversible dynamism between methylation and demethylation of DNA in the perennial American ginseng in response to temperature seasonality. And sufficient cold exposure duration in winter caused sufficient DNA demethylation in tender leaves in early spring and then accompanied the high expression of flowering gene PqFT in flowering stages and ginsenosides biosynthesis gene PqDDS in green berry stages successively, and finally, maximum ginsenosides accumulation occurred in the roots of American ginseng. Conclusion We, therefore, hypothesized that cold-induced DNA methylation changes might regulate relative gene expression involving both plant development and plant secondary metabolites in such cold-dependent perennial plant species.

“…Key terminologies is presented in Table 1. Gady et al (2017) reviewed four epigenetic-based regulations in each phase of the tomato fruit set, development and ripening. Those regulations were included: (1) modifications in histone proteins, (2) methylation and demethylation of DNA, (3) regulation of significant locus by small RNAs through posttranscriptional processes, and (4) lncRNA (long noncoding RNA)-associated regulatory pathways.…”

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.
