“…miR1863 is required for silencing heterochromatin by methylation in rice (Wu et al , 2010). Recent studies show the involvement of the DNA methylation process in high temperature response in plants (Sanchez and Paszkowski, 2014; Naydenov et al , 2015). Imprinting of genes may help in recovery of stressed plants after a heat stress episode.…”

Heat stress can induce the cultured microspores into embryogenesis. In this study, whole genome bisulphite sequencing was employed to study global DNA methylation variations after short-term heat shock (STHS) treatments in cultured microspores of Brassica napus cv. Topas. Our results indicated that treatment on cultured Topas microspores at 32 °C for 6 h triggered DNA hypomethylation, particularly in the CG and CHG contexts. And the total number of T32 (Topas 32 °C for 6 h) vs. T0 (Topas 0 h) differentially methylated region-related genes (DRGs) was approximately two-fold higher than that of T18 (Topas 18 °C for 6 h) vs. T0 DRGs, which suggested that 32 °C might be a more intense external stimulus than 18 °C resulting in more changes in the DNA methylation status of cultured microspores. Additionally, 32 °C treatment for 6 h led to increased CHG differential methylations of transposons (DMTs), which were mainly constituted by overlaps between the hypomethylated differentially methylated regions (hypo-DMRs) and transposon elements (TEs). Further analysis demonstrated that the DRGs and their paralogs exhibited differential methylated/demethylated patterns. To summarize, the present study is the first methylome analysis of cultured microspores in response to STHS and may provide valuable information on the roles of DNA methylation in heat response.

“…Class I: non-methylated fragments, Class II: hemi-methylated fragments; Classes III and IV: fully methylated fragments R. glutinosa to lead to a pronounced decline in the yield of tuberous roots , an effect which was reproduced in the present experiment. The replanting disease syndrome is thought to reflect the modulation of gene expression (Richards 1997;Ding et al, 2014;Yang et al, 2015;Naydenov et al, 2015), most likely arising from epigenetic mechanisms (Fan et al, 2012;Ding et al, 2014). The present MSAP profiling showed that the global level of methylation level was somewhat (about 6.58%) higher in the R2 than in the R1 material.…”

“…There are many documented effects of DNA methylation on plant phenotype, which has an impact on the response to various biotic and abiotic stresses (Li et al, 2012a;Liang et al, 2014;Naydenov et al, 2015). Certain stresses which disturb plant growth and development have been shown to induce alterations in the pattern of methylation of genomic DNA (Ding et al, 2014;Zhong et al, 2015).…”

Abstract"Replanting disease" is a serious constraint to root growth in the medicinal species Rehmannia glutinosa (Gaertn.) Libosch. ex Fisch. and C.A. Mey. The syndrome involves an array of morphological, physiological and biochemical changes to the plant, which culminates in a major loss in tuberous root growth. Here, the tendency of replanting disease to induce differential cytosine methylation in the root DNA was explored via the methylation-sensitive amplified polymorphism (MSAP) method. Exposure to the disease measurably altered the global methylation level. Of the 231 differentially methylated MSAP fragments identified, 136 involved replanting disease-induced methylation and 95 demethylation. A set of 31 differentially methylated fragments was isolated and sequenced. The sequences were used to analyze the function of the genes involved and to investigate whether any were differentially transcribed as a result of exposure to replanting disease. Of the eight genes subjected to transcription profiling, the three which were demethylated in the diseased roots were transcribed more abundantly in these roots, and the five which were methylated were down-regulated by a real-time quantitative PCR (qPCR) method. Our study gives an insight into the DNA methylation of R. glutinosa subjected to replanting disease and provides valuable information for further exploring epigenetic regulation of responses to the disease in the species and other plants.
